A budget communicator from the Middle Kingdom that could be a hit

The current hero of the review has long attracted the attention of the public with its characteristics and price. It became one of the first, if not the first, communicators that made it possible to fulfill the dream of many buyers: to buy a smartphone with a dual-core processor, a large display with a resolution of 720 × 1280 pixels and support for two SIM-cards - for symbolic money for a device with such characteristics.

A "squiggle" happened in the chain of events, and Jiayu G3, namely, he was talking about, ended up in the editorial office after his somewhat alter ego - iconBIT NetTAB Mercury X, a communicator of a domestic company, but with a distinct Chinese ancestry, having a twin brother as UMI X1. But it's okay: the more interesting it will be to compare both devices, because the price tag on them differs almost twice.

Before proceeding with the description of the impressions of the new product, it is necessary to make a reservation that the Jiayu G3 can currently be purchased only in China, it is not officially supplied to Russia.

Scope of delivery and characteristics

Jiayu G3 has perhaps one of the most unusual packaging, at least among those that we have come across: a thin white cardboard cover is put on a transparent plastic box, most of all resembling a food container, which, in turn, contains a smartphone and accessories. It should be noted the strength of this structure, which is undoubtedly important when sending a purchase by mail. At the same time, in order to open this plastic "ark", you need to work hard and suffer a little, especially if you do it for the first time.

No particular useful information there is no communicator on the packaging, for a compatriot only the name of the device, the name of the manufacturer and the address of its website will be clear. The rest of the scant information is presented exclusively in hieroglyphs.

The Jiayu G3 accessories set is standard: rechargeable battery, charger, Micro-USB cable, wired stereo headset and documentation. As a nice bonus, there is protective film for the communicator screen. All accompanying documentation available contains text exclusively in Chinese.

The characteristics of the Jiayu G3 communicator are as follows:

• MediaTek MTK6577 processor (two ARM Cortex-A9 cores, 1 GHz frequency) with PowerVR SGX 531 video core;
• Operating Android system 4.0.4 (Ice Cream Sandwich);
• IPS display, diagonal 4.5 ″, 720 × 1280 pixels, capacitive, with multitouch;
• RAM 1 GB, main flash memory 4 GB (2.5 GB available);
• Support for microSDHC memory cards with a capacity of up to 64 GB;
• Support for two SIM-cards;
• GSM EDGE / GPRS communication (850/900/1800/1900 MHz) for both SIM cards;
• Communication 3G HSPA (2100 MHz) for one SIM-card;
• Bluetooth 2.0 + EDR;
• Wi-Fi 802.11b / g;
• FM radio;
• GPS + A-GPS;
• Position sensor in space, accelerometer, magnetometer;
• Camera with CMOS sensor with a resolution of 8 megapixels, autofocus, LED flash, an additional camera with a resolution of 2 megapixels;
• Lithium-ion battery, capacity 2750 mAh;
• Dimensions 135 x 65 x 10.8 mm;
• Weight 131 g.

The Jiayu G3 and iconBIT NetTAB Mercury X specifications are the same on almost every point. Of course, the two communicators differ in size and weight, but this is largely due to the difference in size and battery capacity of these two devices. In general, the parameters of the Jiayu G3's hardware seem to be very tempting considering the price of the communicator. The main positive point is a capacious battery, negative and mysterious - somewhat outdated Bluetooth and Wi-Fi modules.

It should be noted right away that the described capabilities of Jiayu G3 are characteristic of the firmware with which the device went on sale, and screenshots were taken with it. It is, in particular, based on Android 4.0.4. Meanwhile, at the time of the announcement of the article, a new firmware based on Android 4.1.2 was already available, and at one point, which we will discuss later, the functionality of the device may change significantly relative to the "out of the box" version.

Design and appearance

In the era of struggle for the title of "thinnest smartphone" Jiayu G3 looks very extraordinary - a kind of weighty and thick black plastic "brick". Inadvertently, there is a feeling that it can be used not only for its intended purpose, but also, for example, for hammering nails or as a weapon of self-defense.

Despite the classic body shape and light weight for its dimensions, Jiayu G3 is definitely a man's smartphone. It is in a man's hand that this "bar" looks the most organic and impressive. It is difficult to imagine that the hero of the review will be of interest to the fair sex and, moreover, will fit in a woman's hand.

The thick side edges allow you to confidently hold the communicator with one hand despite the overall slippery plastic of the case. But, unfortunately, the size of the smartphone also limits its ability to fit in various pockets. A comfortable grip, in addition, does not mean that the communicator can be easily operated with the fingers of one hand: in order to reach all corners of the display, which is elongated in length, the body of the smartphone must be intercepted in the middle, sacrificing the reliability of the grip.

Outwardly, the hero of the review resembles several families of devices at once: there is something from Sony smartphones in which the lower part of the case is highlighted, there is something elusive from the iPhone 4 (probably the design of the upper part of the bezel and a cutout for the telephone speaker), but most of all in it from the appearance of the good old communicators with the now deceased Windows Mobile - for example, the E-ten models, which differed most of all in the thickness of the case, Chinese plastic and, in general, "uncomplicated" design. The main impression from the design of the communicator is that this is how a smartphone with Windows Mobile would look like in 2006, if someone in the Middle Kingdom at that time decided to release a communicator without hardware keys, with only one touchscreen display on the front panel.

The Jiayu G3 case is made of plastic and metal, the first of two types: matte black - for most of the case, glossy black - for the front panel and ends. The metal is presented exclusively in the form of two inserts on both sides of the protective glass of the display. They do not look very organic, it seems that the developers tried to use them to make the communicator more "representative", but achieved only the opposite effect. All panels - both plastic and metal - are excellent at collecting fingerprints.

In general, the build quality and design of the communicator are satisfactory. There are no creaks and backlashes between the parts, nothing rings or dangles. The battery cover is held by several latches and detaches with some effort and diligence. The few keys are embossed and have a distinct stroke.

On the front panel of Jiayu G3, in addition to the display, there are three touch keys (all with backlight), a telephone speaker, an additional camera lens, two sensors and a communicator status LED. For the presence of the latest smartphone developers should be praised separately. The entire front panel, with the exception of metal inserts, is covered with protective glass, similar in properties to the well-known Gorilla Glass.

The name of the manufacturer and its logo are applied only to the battery cover, which is the back panel of the smartphone. There are holes for the main speaker, camera lens and LED flash. After detaching the cover, a view of the huge battery, slots for SIM-cards and memory cards opens up (you cannot replace them without removing the battery).

You can remove the rear plastic panel only by picking it up with your fingernail in the lower right corner of the communicator's case - this is where a special recess is located. On the right side of the smartphone there is a double key for controlling the volume of the device's sound system. The left side of Jiayu G3 is empty.

Below the hero of the review there is a microphone and a Micro-USB-compatible connector. Above is the power key and 3.5mm headphone jack.

The layout of all controls in Jiayu G3 is standard, but, however, there are several questions about the layout and design of the communicator. Firstly, it is surprising that there is a large amount of free area on the front panel, which is not occupied by anything - the smartphone could simply be made smaller. Secondly, the bottom of the bezel feels completely redundant, as does the plastic rim around the display. Thirdly, instead of touch-sensitive keys, mechanical ones would be painlessly placed, but the developers followed the lead of fashion. Of course, all this can be considered nit-picking; the communicator turned out the way it is. Moreover, the dimensions of the case may have been dictated by the size of the large battery, which needed to fit inside. As a result, the answer to the question whether the device likes it is different for everyone, but for me personally it is negative - I really want to quickly hide the Jiayu G3 in some kind of cover. It remains only to note that there are also gray and silver versions of the smartphone on sale.

Software

The communicator runs on the Android 4.0.4 operating system (firmware for 4.1.2 has recently appeared). The system is presented almost in its original form, there are no additional shells. Initially, the system is set to Chinese as the main language, so to switch the interface to Russian you will have to work a little and wander around the settings menu.

From the system lock screen, you can access the camera control program or the main screen. There are no custom icons or widgets on its five tabs.

However, there are several additional applications in the Jiayu G3 firmware. They can be divided into two categories: useful programs and not really - at least for Russian-speaking users. The first group includes Flashlight, File manager and Manager of running applications - all of them do not need special presentation and explanation of their work.

The principle of operation of the program for managing two channels of cellular communication is the same for all communicators based on the MediaTek platform that have been tested. The owner of the smartphone has the opportunity to choose which of the two GSM channels will be used in different situations: when making calls, sending SMS and MMS messages, for data transfer. One of the two SIM-cards can be designated as the preferred one, and it will be it that will be used to perform the mentioned operations. Or, you can opt out of this setting and make a choice whenever the need arises.

Display and sound

Like a couple of iconBIT NetTAB Mercury X / UIM X1, the hero of the review attracts the attention of the public with its display: for a budget smartphone, its characteristics cannot be called anything other than wonderful. The diagonal of the IPS-matrix is ​​4.5 ″, the resolution is 720 × 1280 pixels, and as a result, the density of dots per inch (one of the most popular parameters for comparing smartphones in recent years) is 326 ppi. It will not be superfluous to point out again that the pixel density of such a display is higher than that of a screen. Samsung Galaxy S 3 is smaller than the display on the iPhone 4 and exactly matches the pixel density of the Retina matrix in the iPhone 5.

The screen is covered with a protective glass, up to 7 simultaneous touches are recognized, the viewing angles are very comfortable, the backlight brightness is adjusted automatically, but in the bright sun the picture on the display becomes difficult to see.

Alexey Kudryavtsev, editor of the Monitors and Projectors and TV sections, will tell you more about the Jiayu G3 screen.

The front surface of the screen is covered with a glass plate with a mirror-smooth surface that is resistant to scratches. Based on the reflection of bright light sources, there is a very effective antiglare filter to reduce the brightness of reflected objects. There is a special oleophobic (grease-repellent) coating on the outer surface of the screen, so fingerprints do not appear as quickly as in the case of ordinary glass, but are removed more easily. Note that the effectiveness of the oleophobic coating of this screen is quite high.

With manual brightness control, its maximum value was 350 cd / m², and the minimum was 22 cd / m². The maximum value is not outstanding, but in principle sufficient - even in bright daylight, you can see something on the screen. In complete darkness, the brightness can be lowered to a comfortable level. There is an automatic brightness control by a light sensor, which in complete darkness and in an office illuminated with artificial light reduces the brightness to about 50 cd / m² (acceptable), and in a very bright environment, the brightness rises to the maximum. At low brightness, there is no backlight modulation at all, so there is no backlight flickering.

The Jiayu G3 uses an IPS-type matrix, so the screen has very good viewing angles without inverting shades and without significant color shift, even with large gaze deviations from the perpendicular to the screen. True, the black field when deflected diagonally becomes lighter and, depending on the direction of deflection, acquires a red-violet or greenish-gray tint. However, at this smartphone this increase in the brightness of the black field is very weak. When viewed from a perpendicular view, the uniformity of the black and white fields is good. The response time for the transition black-white-black is 23 ms (11 ms on + 12 ms off), the transition between the mid-tones of 25% and 75% (by the numerical value of the color) and back takes a total of 27 ms. There is a certain brightness correction depending on the overall lightness of the image (the brightness decreases for light images and increases for dark ones), but it works only when displaying grayscale images, and when displaying a black or white field (or primary colors) in the entire screen, there is no adjustment. Why such a function is needed remains a mystery, but in the end, although the gamma curve built on 32 points did not reveal a blockage either in highlights or shadows, it had a very strange shape, not in the least resembling a standard power function with an exponent of 2.2:

The contrast is high - 960: 1. The color gamut is very close to sRGB:

The spectra show that the matrix filters moderately mix the components together:

The color temperature is slightly higher than the standard 6500 K, and the ΔE index is quite high, about 12. However, both parameters change little over the entire gray scale that matters, so there are no special complaints about the color rendition subjectively. (The dark areas of the gray scale can be ignored, since there the color balance does not have of great importance, and the error in measuring color characteristics at low brightness is large.)

As a result, in terms of the totality of characteristics, the screen of this smartphone reasonably deserves a high assessment.

Both speakers of the Jiayu G3 are, frankly, unimportant. First of all, this refers to the sound quality: if the phone speaker adds a "cold effect" to the voices of all interlocutors (during a conversation, one gets the feeling that they have a stuffy nose), then the main speaker simply starts to emit a rattle and creak along with low frequencies at full power. Speaking of sound power, both speakers have average. The interlocutors also complained about not very high-quality voice transmission by the built-in microphone. Thus, the conclusion is the following: the quality of the sound subsystem significantly spoils the impression of the hero of the review.

The sound quality of the complete stereo headset, on the contrary, turned out to be at a good level, and its white color and comfortable ear pads caused only positive emotions. However, in any barrel of honey there is also a significant fly in the ointment, in this case it turned out to be a large resistance of the headset speakers. As a result, even at maximum power, the sound from them is not as loud as we would like - for most cases, sufficient, but those who like to listen to music in transport will have to purchase other headphones.

The headset control unit with a microphone and a call answering key is not detachable; a clip is provided for attaching it to clothing.

The communicator is equipped with an FM radio that works only when headphones are connected. The signal reception quality is average, the control program has the functions of automatic search for stations, making a list of channels, recording audio and recognizing RDS signals.

Wireless interfaces and communication

Jiayu G3 is equipped with all the necessary wireless modules for modern life. It can be noted right away that there were no serious problems with their work during the testing of the communicator.

Specifications Bluetooth modules and Wi-Fi look somewhat strange for a 2012 smartphone on the MediaTek platform: for example, only the outdated version of the Bluetooth 2.0 stack is supported, and the Wi-Fi module, judging by its description, is not capable of working in 802.11n networks - only in "slow" 802.11b / g networks. Most likely, this is a limitation of the firmware of this particular smartphone model, since the same iconBIT NetTAB Mercury X, built on an absolutely identical platform, has both Bluetooth 4.0 and Wi-Fi 802.11b / g / n.

Since the hero of the review has one communication module, it is possible to simultaneously make calls or transmit data over two networks (or one, but in dual channel mode) is impossible, despite the fact that there are two slots for SIM-cards.

Unfortunately, nothing positive can be said about the work of the GPS receiver in the Jiayu G3 - they simply did not manage to use it properly. For almost 10 minutes, the satellite navigation receiver was unable to pick up a single signal from the satellites! And this is with the included A-GPS and EPO - technologies that can significantly speed up the process of determining the coordinates. As a result, the communicator was only able to approximately determine its location based on data from base stations. cellular network and Wi-Fi hotspots. The problematic GPS receiver has significantly tarnished the reputation of the Jiayu G3. It is possible to restore its operability, at least there is a description of the necessary actions on the network, but this requires root access and a certain level of skills from the owner of the smartphone. Fortunately, there is information that the new official firmware, which we did not have time to check, the problem with the GPS operation has already been fixed - well, or it has become less pronounced.

Cameras

The cameras in Jiayu G3 and iconBIT NetTAB Mercury X are exactly the same. The matrix of the main one has a resolution of 8 megapixels, it is complemented by an autofocus system and an LED flash. The additional camera on the front side of the smartphone has a light sensor with a resolution of 2 megapixels.

The shooting control program is built into the operating system, so we are already familiar with its interface. In general, it is convenient, but in order to get to the desired setting, you often have to aim at small icons and wade through long menus.

The camera has a great variety of settings, there is no point in describing all of them here. It is worth mentioning, however, that the list of camera modes contains 4 items: photography, video recording, panoramic shooting and panoramic macro photography.

The speed of the camera and the launch of the application itself is high, but the principle of the autofocus system in the hero of the review, as well as in the iconBIT NetTAB Mercury X, takes some getting used to and does not seem very convenient. Instead of setting focus every time you shoot, the system continuously calculates it, constantly focusing on one or another object in the frame. And in the end, the picture may not turn out the way it was intended: either the system will focus in the wrong place, or the communicator itself will move, and the settings will "go down". Of course, the focus area can be specified manually by simply touching the screen in the right place, but, firstly, it is not always convenient, especially when shooting with one hand, and secondly, this operation negates all the advantages in shooting speed, for the sake of which, judging in all, the developers of the program and the autofocus system have established such a strange algorithm for their work.

Be that as it may, Jiayu G3 knows how to shoot the surrounding reality, and it does it quite well for such an inexpensive communicator (although, by and large, the quality of the images, of course, does not stand up to any criticism). The resolution of images can be up to 3264 × 2448 pixels. Video recording is carried out with 720p resolution and 30 frames per second, recording format - MPEG-4, H.263 / AAC-LC. Only the amount of free memory on the card limits the maximum movie length.

Autonomous work

The capacity of the regular Jiayu G3 battery is an impressive 2750 mAh. Frankly speaking, few smartphones on the market can boast of such a "thrifty" battery.

The presence of a capacious battery, coupled with a very economical platform, should, in theory, ensure a very long-term operation of a Chinese smartphone in offline... Only a large and bright display can spoil the statistics here, but whether this is so - only tests will show.

So, in reading mode e-book with automatic brightness control of the backlight, the communicator worked for 17 hours. Listening to music with the screen turned off discharged the battery by 20% in 15 hours: unfortunately, we did not have enough time for a longer test, but even by this indicator one can judge that in this mode the smartphone can work for several days. The last test is 1080p video playback, its result is 4.5 hours of continuous operation of the Jiayu G3.

The conclusions are unambiguous: a capacious battery and the MediaTek platform allowed Jiayu G3 to become one of the "longest-lived" devices of this class on the market. He lost only a little to the record holder - communicator Philips Xenium W732.

Performance and speed

The capabilities of the MediaTek MTK6577 processor are already well known to us; together with their younger "brother" - MTK6575 - they have firmly established themselves in the SoC segment for budget smartphones, which began to appear in large quantities on the market, and some of them managed to visit our editorial office. We examined the combination of MTK6577 chip, 1 GB of RAM and a display with a resolution of 720 × 1280 pixels in terms of performance in the iconBIT NetTAB Mercury X review, so there is no reason to expect any revelations in this regard from the Jiayu G3, and its capabilities are easy to predict ... However, you can and should check the smartphone in performance tests from our traditional set in order to be sure of the forecasts.

Quadrant Standard:

The assumptions turned out to be correct, the results of the iconBIT NetTAB Mercury X and Jiayu G3 tests are on the same level. Both communicators demonstrated good performance for budget devices, at the level of top-end smartphones two years ago. Of course, they cannot compete with the flagships of the past, 2012, but, given the HD-resolution of the display, one can only be glad that inexpensive communicators are able to satisfy the needs of most users in most tasks. The sluggishness of the operating system interface is still encountered in some places and sometimes, but in general there are no annoying moments, and the rare "brakes" are easily explained by the peculiarities of the Android OS itself.

It remains to look at the results of two more benchmarks and test the HD video playback capabilities.

Support for hardware HD video playback, as such, in the Jiayu G3, as well as in the iconBIT NetTAB Mercury X, is missing. The capabilities of a single processor are not enough for smooth playback of "massive" videos.

Along with the update of the operating system to Android 4.1, iconBIT NetTAB Mercury X now has support for hardware video decoding in H.264 format. With a high degree of probability, this happened in new firmware Jiayu G3. How smooth and high-quality playback hardware decoding can provide can now be seen if you follow the links in the table presented earlier. All videos were opened with a standard player.

conclusions

Regretfully, but I have to admit: Jiayu G3 disappointed. Initial positive impressions gradually changed to negative ones. The desire that once arose to purchase a communicator with similar characteristics finally disappeared after a problem with the GPS receiver was discovered. But even before that, the opinion of the communicator was spoiled by average-quality speakers and a microphone, as well as a lurid design.

The probability that the mentioned problems are peculiarities of a particular instance, of course, exists, but playing the lottery when ordering a smartphone from China seems excessive. Especially if you consider the presence on the Russian market of an almost complete clone of the review's hero - iconBIT NetTAB Mercury X, in case of purchase of which at least there is someone to make a claim and return the purchase.

By and large, the Jiayu G3 has only one advantage over the iconBIT NetTAB Mercury X and its Chinese twin UMI X1 - a 2750 mAh battery and, as a result, longer battery life.

The appearance of the communicator is a matter of taste, but subjectively, the combination of different body materials and the abundance of empty, unoccupied space do not paint the smartphone. A small plus sign is the presence of an LED indicator.

When asked what will outweigh: the disadvantages of a smartphone, albeit potential, or its attractive price, opportunities and an abundance of various "bonuses" from Chinese sellers (a cover, a bumper and a second battery can be obtained for free) - everyone can give an answer on their own. In the end, you can order the same UMI X1 if you really want to save some money.

Good day to all! I've been sitting on Muska for three months now, so it's time for me to write my first review. Just the reason - the arrival of a brand new Jiayu G3S.

The phone was bought for a special offer, plus an additional battery was ordered for $ 5, so here's the total price of $ 180.99. An interesting confusion with add. battery - a little later :)

This is not my first purchase on Aliexpress. Prior to that, the Jiayu G3 and the cover for it were purchased. I already sold the G3 and did not think about the review, but I also use the cover with the current phone, I will review it a little later.

The first step is tracking. 23 days from the date of receipt of the correct track (25 from the date of receipt of the wrong one). Well, against the background of 36 days of anxious waiting for the first G3 - a pretty good result. There were also problems with the receipt - the stubborn "workers" of the Russian Post, in a rather rude and mocking manner, announced to me that they would not look for anything without notification. I had no time to wait for a notification, so after the threat of writing a complaint about them, they immediately had a desire to find me a package.

Now I suggest that you look at the characteristics of the phone indicated at the time of purchase (now they are selling G3T in full and have changed the characteristics to new ones).

Now let's start the review directly. Package. It is a phone box wrapped in one layer of bubble wrap.

Now the box itself. It is made of thick cardboard, it looks quite presentable, but the edges are jammed - i.e. for a gift will no longer fit. Though…

We take out the very bed of the phone and accessories from the cardboard box. What do we see there?

In bags.

Without them.

Here we have:
-telephone;
-battery Li-Ion 2750mAh;
-battery Li-Pol 3000mAh;
-USB-cable for charging and connecting to other devices (by the way, there is no OTG support, I said before I forgot);
-Z / U and an adapter for a euro socket;
-headphones;
- a list of stickers with information about the device;
-protective film on the screen.

What surprised me was the absence of any hints of instructions. Later I realized why - they sewed an electronic instruction in Chinese directly into the phone. The move is quite controversial. I apologize, I don't have screenshots (whoever has - share, add to the review, I didn't think about them right away).

Close-up of a sticker with device information and IMEI.

Externally, the G3S differs from the G3 in the designation of the slots for SIM cards: in the G3 they are designated "G" and "W" like; G3S has SIM1 and SIM2.

Now the batteries. To begin with, two original Li-Ion 2750mAh batteries were supposed to arrive. And the original Li-Pol 3000mAh arrived (these come from the 1.5 GHz G3T) and the fake Li-Ion 2750mAh (weighs 44 grams instead of 54). The seller resisted and by hook or crook proves that this plant supplies fake batteries. I asked for a moneyback for this - there was zero response. If tomorrow does not answer, I will open a dispute. In the meantime, here's a photo of the batteries.

We charge a 3000mAh battery in the phone, insert an MTS SIM card and a 16GB flash drive. Everything goes with a bang. By the way, about the battery - supposedly 2750mAh started up right away; 3000mAh only by charging, although it was 55% charged approximately.

And let's go straight to the review of the phone's appearance, although it seems to me that everyone has already seen it. The left end is empty; on the right - a volume rocker, with which you can still unlock the phone (and the "+" on it allows you to take a picture in camera mode); top edge - 3.5mm jack connector and on / off button; at the bottom there is an inverted micro-USB connector and a hole for a microphone.

The back panel is VERY easily soiled, as many have already said, and on a silver phone (I had a silver G3) it is not so noticeable. That is why such a beautiful back surface ...


... turns into something terrible in the blink of an eye.

By the way, about the complete film. It was enough for me for a couple of days. Now I know that I have to be careful. Already ripped off. We must look for a high quality and matte finish.

Now the bumper. Looks pretty decent.

However, as soon as you put it on your phone, some problems emerged. It seems that this bumper is one of those that are made anyhow and cost less than a dollar. From below, he did not sit at all at first, but after a couple of days of use it seemed to take shape and now the situation is better.

Now the z / y and the adapter for the euro plug. Honestly - I still do not understand what current the s / y is designed for - probably stupid. The 3000mAh battery was charged in ~ 3 hours. It seems like they found out that s / y for 1A. Having picked up the adapter for our plug, at first I thought that it would fall apart - it felt like a completely unreliable thing. But I seem to have withstood a couple of charges already, so it's not all that bad.

I would also like to say about the headphones. This is just the case when there is no desire to throw away the complete headphones as soon as possible. With small external differences (no identification marks Jiayu), these ears have already been described by a comrade.

Well, I suggest you compare the sizes of cardboard boxes from Jiayu G3 and Jiayu G3S. Unfortunately, I didn't have a plastic case from the G3.

It's time to start the phone. And the first thing we see is an excellent 4.5-inch IPS display with a resolution of 1280x720 pixels, covered with Gorilla Glass (and I have no reason to doubt that). I don't know how much I managed to convey his steepness in the photo - probably not how much. But the display is great.

Now let's move on to testing the camera. The front one is declared as 2.0, and in principle it looks like the truth. Unfortunately, I didn’t take pictures with it. Therefore, I will show you the pictures with the rear 8-megapixel camera (which I squeezed to 40% of the original size; this did not affect the quality in any way, in general you can have an idea of ​​the quality. 4mb).

Panoramas are not bad for the phone. I was persuaded, the panoramas are terrible. But there is.

The phone is preinstalled with not the cleanest Android version 4.2.1 with root, a pack of Chinese programs and a launcher from Jiayu (which, as far as I understand, is taken from LeWa OS and remade). It even has interchangeable themes.

AnTuTu results that I got on this firmware.

Then I, one might say, freaked out and sewed MIUI OS based on Android 4.2.1 into my phone. Recovery TWRP was installed in a minute, in another 3 - MIUI itself from the recovery. For 2 minutes it started up, after which the phone was ready for work. Personally, I liked this firmware much more than my native one.

However, AnTuTu Tester showed about 600 fewer parrots.

Wi-Fi test, 2 meters and 15 meters across 2 brick walls from the router, respectively.

Honest multitouch for 5 touches.

35FPS in NenaMark2.

I will not show the GPS Test - the phone saw 11 satellites, but it did not want to connect to them after 3, 5, or 10 minutes (In use - 0).

In addition, I came across a problem known among the owners of G3S - the vibration motor overheats and refuses to work for some time. The solution is to replace it. But it doesn't bother me.

In general, what do we have?
+ Excellent display;
+ Excellent performance for a reasonable price;
+ Gorilla Glass 2 (whoever says anything, I personally tend to think that it is there);
+ Solid appearance(not that remnants of Gnusmas, IMHO);

Unexpected actions of the seller;
- Extremely easily soiled plastic of the case.

EDIT: adding information.

First, about the sound. The speaker is good, the interlocutor can be heard even in crowded places. The external speaker sounds very good and loud, and even at the maximum it does not break into a wheeze and continues to play at a good level.
Of the not-so-bad headphones, I have the Explay MPH335 earplugs (honestly, nothing else). The phone "pumps" them to the fullest, the sound is loud and clear, the bass is there, and very juicy, I like it.

Now about GPS. The method described by a friend in the comments helped, namely:

With GPS The solution is very simple - give it the Internet (and not take away), turn on all sorts of EPO and AGPS, let it find satellites and forget about the problems. On G3 - it was determined in 30 seconds after it was found in 4-10 seconds.
Well on par with the galaxy note n7000

I tried to do as he described, and - oh, a miracle! Cold start about 2-3 minutes, sees 8 satellites, uses 6.

We turn off the Internet, restart the GPS, what we see.

Everything really worked easy.

Now about the time of work. So far, I do not risk pulling the fake 2750mAh, although the day went away with it, and quite successfully. Now installed 3000mAh, with very intensive use by the evening, 20 percent remains. If only for calls, an hour and a half of the Internet and the same amount of games, then two days are enough calmly. Eats 1-2% per night in the usual (not air) mode.

Please note that this is my first review and I tried to do it as well as I can. I would be glad to hear criticism or requests to add any information that interests you.

I have been using it for almost 2.5 years, a very good phone model of its kind, the price is fully consistent with the quality, I used it carefully, dropped it to a minimum, even wet it a little, everything went well and works fine, even retained its presentation.

Show more

Advantages: Design - very nice design, affordable price, I took it in 2014, almost 5k rubles, despite the fact that the analogs of this phone for such a price were at times inferior to this model, a good camera, autofocus, RAM.

Disadvantages: There are gaps (slots) where the screen is clogged with dirt and dust, water can get in, glitches with gps, although it can be solved somehow programmatically, through the firmware, a small memory of its own, but in principle it is difficult even to attribute this to the disadvantages, battery - I thought it would take longer to keep the charge with active use, if you actively use it, then it will not be enough for a day, if it is rational, then you can stretch it for three days

I worked my three years of very active and not very careful use for 5. It still works, but there are too many errors on one device

Show more

Advantages: I don't play toys, I needed a phone for work and coped with this task perfectly. In the first 2 years of my life, I quite decently pulled up to 5 applications. The camera is excellent in good light.

Disadvantages: with constant use, the battery is barely enough for 8 hours of operation, but it is worth giving a discount for the fact that every other day I dropped it very much every other day, but every day. Two years later, the flashlight and autofocus, buttons stopped working, a very funny bug appeared: in the middle of the day, the phone rewinds all actions, until the alarm clock rings, and it does it in a couple of minutes: remember your day in two minutes.

After 1.5 years, it began to freeze in sleep mode (with wi fi turned on, every hibernation, and without it, 5.6 times a day), the service did not help, after half a year a purple blackout appeared in the center in the photo. This is China for one year. And my wife bought a G5S and after seven months a spot appeared on the screen, but so far at least it works without glitches.

This is generally good China. I was not lucky with WiFi, others did not seem to have any problems. I took it for $ 220 (6800r) in China in 2012. Enough so far, I'm not going to change. They work without brakes: the Internet, Yandex applications, a reader, WSP Office office documents, remote administration (RDP, TeamViewer), a USB flash drive, a USB modem mode simply saves if the stationary Internet breaks when playing poker, pictures for information, barcode recognition , skype, ICQ, navitel, 2gis, organizer, reminders, Tower Defense games, PS and 888 poker clients. Well, for the latter, a tablet is better and more convenient.

Pluses: Screen (no dots, HD) Price! Battery Build quality The camera is fine for a phone, but doesn't like room lighting. Support for SD 2x SIM Well sewn without problems Glass - not a single scratch - there is no film and cover (almost 3 years already) In general, the filling is very good for its price. In the mode of reading books and dialers - I keep it for 6 days (without data transfer, WiFi and a navigator. It is necessary to ensure that the processor does not stick at the maximum)

Disadvantages: The back cover does not like to be opened often - it breaks along the edge. GPS - not how it failed to fix it - it clings for 5-15 minutes on any firmware without an Internet and with any patches - it catches badly in the car, you have to keep it outside the window until it catches satellites. WiFi - on the stock and its clones (4.0), I was always torn 2-3 times per minute, on firmware based on 4.2 WiFi is stable, but there are other jambs - black screens after calls, freezes, reboots during a call, mixing up the internal memory with the correct configuration of drives (depending on the firmware). PS: I finally found a firmware that works fine - on w3bsit3-dns.com from Xperia. Only 1 noticeable minus - after charging, the percent sticks to 100%, it seems to be being treated, but I just overload and pass. I also added the microphone volume to myself.

in 2014 he took from China for 5500 rubles. I took it for myself and my brother. Keeps the battery for 2 days. The phone looks like a brick, it's just huge. Normal cheap phone, a typical Chinese. With "Chinese" flaws. But I have never failed. It's definitely worth your money. Was cheap BEFORE the crisis =) now decide for yourself.

Advantages: Price Battery 2 sim cards Camera is normal

Disadvantages: Buggy - turns off by itself once a week. In the cold, the screen does not work - it starts to press itself in a random place. The back cover was covered with scratches for a month. The proximity sensor is buggy - half a minute passes before the screen lights up after a conversation. The front panel fell off - it put a moment on the glue.

5 months of use - the top metal insert fell off - glued back. 8 months - the battery died, I ordered a new one. 14 months - two dead pixels appeared, the screen dies. As a result, there is not enough quality. It seems that everything is fine and functioning, but the quality ... I bought a simpler cheet for my mother, there is also a light + the touch is turned on. I will not take this company anymore.

Advantages: Good sound, the features / price were good when I bought. Beautiful front panel. Good gps.

Disadvantages: The battery lasts a long time, but starting from 30% it melts in 2 minutes to 5%. I got screen flashing from the very beginning. The touchscreen grid is visible. Scary back panel. Dumb rubber covers.

I bought a little over a year ago. I bought it for the sake of sports interest to look at the Chinese technology, well, to use it a bit. Then the corporate tariff changed and I got as much as 10 GB of the Internet, and on my old samsung s3600 there is nothing to do on the Internet. And he began to use the Chinese. And I liked it. I did not reflash anything, did not change anything. I put Russian, removed some of the icons with hieroglyphs and that's it. I have a consumerist attitude to phones - there is nothing to blow off dust particles from it. The phone is for me, not me for the phone ... I occasionally drop it, a couple of times I fell on the asphalt, a couple of times on the concrete floor. The panel flew off from the speaker, glued "a moment and I use it further. I use Yandex plugs, I look at mail, I make pictures and send them by mail, I call, and very rarely write SMS. I practically stopped using the tablet, which I had previously used for the above purposes. Only I watch movies on the plane on my tablet. The rest is all on smart. Immediately I bought myself a charger and an additional battery. It's convenient. When I bought the phone it cost a little more than 5000 TR for that kind of money, there are no drawbacks. The quiet sound of the call was cured by installing an mp3 melody. to a call and some kind of program with an amplifier ... I did not stick the film, since it was like "Gorilla Glass", a normal rubber cover on the body. From the edges of the frame, the paint slowly peels off from drops and indifferent attitude. In general, I am satisfied with everything.

Advantages: Good price to the whistle with exchange rates and the rapid fall of the ruble ... Rich functionality. Tenacious. The ability to replace the battery and charge it separately from the phone ...

Disadvantages: Minor glitches and "indelible Chinese"

If we are talking about JIAYU JY-G3 MTK6589T, then I can’t say anything bad, I had it for half a year until it was stolen, the photos are for 8 megapixels, they are not bad, but only in good weather, in bad weather, the contrast increases and some shooting details are not at all read, go into darkness. (see examples of photos here: https://fotki.yandex.ru/users/alexander-lazorenko/album/222437/) I put the game with races, I drove it until I got tired of it, I didn't see any lags, by the way, it's better to install another camera, for example: Camera FV-5, you get a lot manual settings except of course the diaphragm, i.e. the background sharpness adjustment is not real, the video is not there. It is better to shoot a video on a native encoder (for an example of a video, see here: https://www.youtube.com/watch?v=_H-BDdPe0vk by the way, after being driven to YouTube, he started to twitch for something, and so on a computer from the original it smoothly shows) , I had misunderstandings with calls, for some reason the sound sometimes disappeared on calls, you increase it works and they call, you can not hear it at all, If you put the sound with vibro it worked fine. If you fly without vibro and do not indulge, then the charge was enough for 8.5 days, to be honest, to be honest, I was surprised myself. Wify plows perfectly, TV channels from neta naura, installed Skype, but for some reason it went into shutdown mode when the Internet was supplied, and constantly had to re-enter it with a password and login, Probably if NET is active all the time, it should work, as seen from skype so-so, but if you switch the outdoor camera, it becomes cleaner. Headphones through bluetooth also work perfectly, really, the batteries quickly sit down in the headphones.

How long have you had this device?

Already 10 days since I received it.

Do you use it until now? If not, why did you break up with him?

Not using. I gave it to my wife for temporary use. Let him get used to good things.

How did you get this device? What were the criteria for the selection? Where and how much was purchased?

I ordered it on Aliexpress. I looked closely for a long time, read thematic forums. Selection criteria - reliability, long-lasting battery, camera with flash, Gorilla glass on the screen, viewing angles, behavior in sunlight, two SIM cards, Android 4.2, quad-core processor, at least 1 GB of RAM, screen size no more than 5 inches and resolution not less HD. I didn’t buy for myself, for my son, a second-year college student, and on his scholarship. But, as always happens, although he participated in the choice, I slipped the options to him. So we chose "together" what I wanted for myself. I ordered it on the 20th of November, and on the 21st of December I was holding it in my hands. The seller sent it by Singapore Post. The journey from China to Kazakhstan took about 3 weeks (including the preparation and verification of the phone by the seller), and the parcel went through Kazakhstan for a week.

The price of the phone at the time of purchase was MNT 169.99. She has grown slightly now. The set included a gift silicone case and a stylus. For some time now, the second battery is not included in the set of telephones sent by mail due to the restrictions of the postal services.

Unboxing video:

First turn on:

What do you like? Strengths, dignity.

The slab-like body of this phone doesn't look so monotonous. True, some still see in it a similarity with other brands, such as iPhone for example. I don’t know, I don’t have such associations. But the Samsung paddles had time to pall. Moreover, they have become the favorite telephones of the female part (its young part) of the population. Almost every second girl under 30 walks with a phone over 5 inches.

So, I repeat, the size of 4.5 inches today is the lower limit of the screen size of a phone that claims to be an HD screen. You can, of course, fit the same number of pixels into a smaller size, however, there will be no sense. And the shape of the case, angular at first glance, evokes a feeling of reliability.

I want to explain myself right away. Why don't I call my phone by name? I, of course, know how his name is read. Jiayu G3S. I specially launched GoogleTranslator to listen to how it sounds in Chinese. It turned out something like Dzya-U-I. Call this good telephone so I can’t, my tongue doesn’t turn. To call, as on the forums about him, "chew" or in general "Egg" - too, because I like him. In what follows, I will simply refer to it as a smartphone or a telephone. That's what I call at home.

For those who did not bother to watch the unpacking video, I will tell you what exactly came in the box. For the video, by the way, I apologize, I shot with a camera that does not have the function of recording video in HD quality, and I still can't buy a tripod for it.

So, the box contained:

the phone itself is in a green silicone case and with a glued transport film;

1 A charger with a Chinese (well, at least not ours) plug;

adapter for the charger to our sockets;

USB-microUSB cable for connecting to a computer and for a charger;

film on the screen;

the stylus put by the seller (as well as the cover) as a gift.

Equipment:

Phone types:

To be honest, the green case of a toxic acid color caused a slight shock. I ordered a black phone. It goes without saying to me that the cover should also be black. But that's what I thought. Phone makers, it turns out, do not take into account the wishes and put cases in boxes on a random basis. Well at least they didn't put pink. I expressed my "phi" to the seller, but by that time the combination of colors green-black had already become familiar and even familiar. I'm not offended for the cover on the seller. By the way, a cover for this phone is not a luxury, but a necessity. According to reviews, the black paint from the sides of the phone next to the screen begins to peel off over time, and the cover protects against this. And, of course, some kind of protection in case of falling. Another plus of the cover - the phone is held in hands like a glove, does not strive to slip out.

Frame

Heavy, metallic. Of course, it is not all metal. I do not mean a screen - it is supposed to be glass. But the back cover of the battery compartment looks flimsy. This feeling appears when you take it off, it is thin, the latches unfasten with a crunch, causing fears for their integrity. But in the assembled state, the phone feels like a monolithic (and it does not creak or play) a black bar, pleasant to the touch. The surfaces are smooth, but does not slip out of the hands. It gets smeared with fingers quickly, it is also quickly rubbed off. The screen has no oleophobic coating, and the fingers remain. I pasted a film on the screen. I didn't stick to my own - I went to the service, paid for their matte film, and they glued it to me. Enough for a while, with a matte film, fingerprints on the screen are less noticeable.

Silicone case, sat on the case perfectly. It has become much more comfortable to hold. A kind of replacement for softtach. About the cover I can say one more thing. It has a rough surface and gets dirty quickly in the field. And since the surface is not smooth, it takes effort to wash.

Screen

The screen size is just right for one-handed operation. In most cases, the second hand is unnecessary. Well, unless you press the screen lock button, it is not quite conveniently located at the top. But unlocking also works from the volume control keys. The volume down key can be used as a shutter button in the camera application. I haven't figured out yet how autofocus works.

More about the screen. The viewing angles are excellent in my opinion. I specially took pictures from different angles. No comments.

Cameras

The main camera of the phone. It is eight megapixel. In order to, on occasion, film the bus schedule, a beautiful view, a child who is not averse to posing - all this is possible with good lighting. There is autofocus, and it even copes with its task. But not fast, in low light conditions it slows down even at home. However, it is an ordinary telephone camera, not KarlZeis, of course.

Below are examples of photos.

In the camera settings, you can set it to "full screen". With this function, the phone takes pictures with an aspect ratio of 16:10 (maybe 16: 9, there was no time to check). But at the same time, the maximum resolution is reduced to 6 megapixels. That is, in fact, 2 extra stripes at the top and bottom of the photo are cut off. I don’t presume to judge, but such a decision seemed strange to me. The functions include panoramic shooting (there is, okay, the quality is disgusting, made for show), shooting a 3D image (this is when you shoot an object from different sides and you can also view it, but only on the phone), quality settings, etc. Didn't understand, didn't test all of them.

Although the front camera is declared 2 megapixels, I'm somehow not sure about this. She has a very poor quality. In order to capture a self-portrait for an avatar on a forum or in a Google account, more will come down.

Video filming. Both cameras support HD shooting. Frontal supports quoted.

See examples below.

I hope you are not offended that I did not shoot a longer video? In my opinion, everything is clear. For some reason I was hoping for the best. Maybe things will be different in good lighting?

Performance

Well, I went to the place where this phone is on horseback.

The MTK6589T processor with 4 cores of 1.5 GHz, with 1 GB of RAM in a pair gives sufficient performance for almost all tasks that may arise. Recently, people still complained about the brakes even in the Android interface. Now the time has finally come when you can forget about it. I had no reason to complain.

Below are screenshots of benchmarks.

Operating system

The operating system Android 4.2.1 is installed, not naked. A number of applications unnecessary for non-Chinese are preinstalled.

Your lunch. You need to get used to it. But after a couple of days, the desire to put, for example, Apex - was gone.

Ruth was out of the box. Therefore, it was not necessary to look for ways to rut. Titanium restored everything from another android device, demolished the Chinese, and that's it, the settings are over.

About the built-in memory: part of 4 GB is occupied by the system. The remaining 2.8 GB are allocated for installing applications. There is no room for the built-in flash card at all. Therefore, without an additional flash card, it is impossible even to take a photo. To some, the decision will seem controversial. For such, there are always programs for repartitioning the phone's memory or simply rolling another firmware. Fortunately, there are many of them in the open spaces of w3bsit3-dns.com and china-iphone. For example, the same LewaOS. I didn't install it just because the phone was not intended for me personally. And the pluses of the fact that all available built-in memory is allocated for applications are obvious. No need to puzzle over where to find the downloaded file, which sdcard, external or internal, for example. Well, of course, everyone has their own preferences. And now it's not a problem to buy memory cards.

Another plus that I almost forgot about is status LED... When charging, it lights up red to 90% of the charge. Then green, which can be confusing (the charge hasn't finished yet). When discharged to 15%, it also signals in red about the need to find an outlet. In fact, you don't have to worry too much, for a couple of hours or even more of the charge this will be enough (if you do not continue to play or download something big). It also signals green about missed calls, SMS and other messages. Comfortable.

About battery capacity I can say a little - the Antutu tester knocked out 600 with a small score. These are parrots. During use (several days) I charged every other day. Not very active use was enough for two days.

Battery consumption screens:

Pictures of the charger:

I did not use my native charger. I have several of them from other phones. The cord is a bit short, so I use the charger with the longer one. I did not test charging for speed. Charges overnight and okay.

Multitouch

I describe it simply because the first time I encountered a 7-touch multitouch. As the saying goes, "neither two nor one and a half." 5 touches, it seems to me, would be enough for the eyes. When I tested, I barely fit these same 7 fingers on a kind of rather big screen.

Multitouch test:

Navigation

Yes, I tested it. Yes, I got the result. Cold start in 111 seconds on a windowsill in an apartment (3rd floor, facing south-west into the courtyard of the same 6-storey buildings). Previously, using a header from the forum on china-iphone, I configured it. This test was made for the sake of the test. Navigation itself is needed like a mare's fifth leg.

By the way, there are a lot of reviews about GPS malfunction in this phone, that sometimes it is necessary to re-solder something there. Perhaps this is so, but I passed by by the side.

Sun behavior

Here are photos of the phone in the sun. The photographs, I must say right away, were taken at home, for the only reason: the frost hit at 20 degrees, and I did not smile at all to go out with a phone and a camera in my hands. The photographs give a general idea of ​​the headroom of the screen. It is possible to make out (and what is there to see - see) and read the message written on the screen even in bright light, well, maybe you have to cover it a little from glare with your hand. By the way, I did not check the automatic brightness control, and I don’t presume to say how it behaves.

Photos of the phone screen in the sun at maximum brightness, at medium and at minimum:

Telephone component

Calls, dials, you can hear the interlocutor, you can hear me. Everything is standard. When installing a new SIM card, it asks which one to use for voice calls, which one for video (and for 3G, respectively). You can configure it to always ask which SIM to call, which message to send. In the phone book, you can bind a number to a SIM card. I have seen something else only at LewaOS. There, the dialer interface allows you to select a SIM card for calls by moving the slider under the dialer.

About communication standards

Both SIM cards support 3G WCDMA2100 standard and no other. That is, if your favorite provider works in a different standard, then you will not see 3G as your ears. I ran into this, "burned out" and put the unsupported SIM card on the shelf for a while while I had the phone. With two other providers that we have in our area, the phone works without any problems. The connection parameters had to be hammered in manually, I did not pick it up myself. And the speed was 64 kbps. After 2 days of trying to figure out what I was doing wrong, I called support - they rebooted something there, I turned off and on the phone, and oops - the speed of up to 7 Mbps increased for reception. And I sinned on the body.

HD video playback

Especially for such cases, I have 2 test videos in FullHD-quality on the flash drive (trailers of some films). The stock player played both of them, but one of them was silent. The reason is that you need to disable hardware decoding, but in the settings it does not have it. I used a standard MX-player for such cases. Both are played, and with sound. A very controversial issue about the need to play such a video on a small screen. Films never weigh so little. There are 7 GB or more. Is it better to use a TV? Or a computer with a good screen?

Games

For the test I installed Real Racing 3. My son played. What can you say? Brakes appear, but only with a large number of cars. There is an image in the rear-view mirrors. The son did not feel any discomfort during the game. He will hand over the session, get the phone back (if he handles it well) and test it again.

What's not to like? Weak sides, limitations.

Its front camera is weak.

What are you missing in it?

WCDMA900 for tele2.

What features do you use frequently?

Skype. Viber delivered. Reader. Internet. Gmail. Camera.

What features do you use occasionally?

Mail.ru agent.

What functions are you not using at all?

Bluetooth did not even check. Now I don't have a headset (I gave it to good hands as unnecessary until I died of old age), and I was too lazy to connect to phones.

Did the device have to be repaired?

No, and I hope not.

What kind of troubles happened with the device? What glitches have you noticed?

There are no such.

Try comparing this device with other models you have used.

An extremely good Chinese smartphone. Maybe because of the economy, I had to deal with devices that require some additional steps to configure, finish, reflash, etc. But this apparatus does not need this. All operations to fit the smartphone to fit took 2-3 hours, including restoring applications from backup and photographing the unpacking process and the first start-up.

What else can you say?

This is a work phone. Not for entertainment, show-off, toys. While it is suitable for all these purposes, the processor and memory allow you to do almost everything on it. But, again, this is a reliable phone for work. I lost interest in him a little when I realized that there was no need to tweak and tinker with him. The quality of Chinese smart phones (and not only smart ones) is growing and very noticeable. Let's wait for the opportunity to test something 8-core.

9 out of 10. Took away one point for not having the WCDMA900. I recommend it to everyone for purchase.
