Cyclical reboot of a Samsung smartphone: causes and solution to the problem. Samsung Galaxy reboots on its own - Samsung s3 solutions reboots

If you have been the owner of the Galaxy S3 for a long time, then you could have got into a strange "event" - the phone turns off and restarts for no apparent reason. Don't worry, because you are not alone and Samsung is aware of these situations.

The post appeared on Reddit and currently has over 150 comments written by members of the XDA-Developers community discussing the sudden death of the Galaxy S3.

A little more than a month ago, a similar topic was even raised, which collected more than 60 pages of discussions, and at the time of this writing, it was already known in detail when and because of what the Galaxy S3 could go into clinical death. The user TurtleRecall was able to describe the problem more summarily.

At the time of his comment on the XDA forum, the discussion had already gone up to page 56 and users were constantly writing that their flagship had suddenly passed out. The device can work from 150 to 200 days and then only something like this can happen. If the user did not manage to get root-rights or install custom firmware, then Samsung could still change the device under warranty.

It has been speculated that the NAND is corrupted and that is why the problem arises. It is troubling that Samsung has already replaced boards of the same make, which raises a big question about the general problem of smartphones released 6 months ago or so.

A similar thing suddenly happened with my friend's smartphone, although he did not install himself any custom firmware, or even root-rights. And I was constantly on official firmware from Samsung, upgrading from ICS version to Jelly Bean. Samsung does not officially admit that there is a problem, but after contacting service center we witnessed that we were not the first with such a problem, and recently there have been a lot of such calls to the Samsung call center.

It turns out that the board in the Galaxy S3 was dying for no reason and Samsung changed them for free, although the replacement was again with the old-style boards, and therefore the smartphone may die again after a few months, or even earlier.

This is not the first time we have reported this problem with a popular smartphone. Again we see that no device is perfect and regardless of the operating system on which the device is running, some problems still appear. However, this does not mean that this should happen with a smartphone.

Anyway, we do not know the true scope of the problem, because there are no comments from Samsung on this issue. However, we believe that only a limited number of Galaxy S3 units are affected by sudden death. Otherwise, we would have seen a more resonant discussion.

Although today is December 21, and maybe that's why the Galaxy S3 began to die almost in droves? Supposedly the end is near? Joke.

Seriously, we are waiting for your comments and opinions on this topic. Have you faced this problem? If so, how did the official Samsung service help you?

Samsung constantly reboots

Although Samsung Galaxy is the top model of a global brand, it, like many smartphones, can fail and start constantly rebooting. Such a breakdown may be caused by a malfunction of any program or operating system on which this phone is running.

A hardware failure can also cause problems, as a result of which the smartphone will constantly or periodically reboot.

note

Such behavior of Samsung Galaxy will cause a number of inconveniences to the user, and in the worst case will lead to a complete loss of data on the mobile device and the inability to use the gadget for its intended purpose.

What to do if Samsung phone keeps restarting? Let's consider several reasons for such a malfunction and try to find ways to eliminate it.

Reboot reasons and how to fix them

Many users, as well as more experienced service center specialists, identify several main reasons why Samsung Galaxy is constantly rebooting:

breakage of power contacts or lithium-ion battery;
mechanical damage to the phone;
failure of the system board as a result of oxidation of contacts or conductive connections under the influence of moisture;
module failure random access memory or processor;
incorrect operation of one or more applications;
destruction of the nucleus.

We will try to independently identify several reasons for the phone's malfunctioning and, if possible, fix the problem without resorting to the help of experts or a service center. First, you need to determine the nature of the malfunction, that is, what caused it.

All types of breakdowns can be roughly divided into 2 types:

mechanical damage- occur if any of the parts of the phone fails;
software problems- caused by incorrect or wrong work any system application or third party program on the phone.

note

If Samsung Galaxy constantly reboots, responding to user actions (for example, pressing a finger on the screen sensor), it must be put into a safe mode of operation. With this launch, the device loads only basic system applications.

Everything extraneous programs installed by the owner of the handset after activating the device, in this mode will be forcibly disabled.

Safe mode

Safe Mode is activated on all Samsung Galaxy phones in the same way. Let's take a look at how this is done on the Galaxy S6 Edge as an example.

To enter safe mode on this device necessary:

While holding down the power off button, select the "Turn off" option. Wait until the smartphone screen goes out completely and does not take any action.
If the model of the problem gadget provides removable battery then the most in a simple way turning off the phone 100% will remove the lithium battery and leave it in this position for a few seconds.
Replace the battery and turn on the Samsung Galaxy phone.

It's important to know

At the time when the manufacturer's corporate logo appears on the screen, you need to hold down the lower key of the volume carriage, that is, the "Volume -" button. If all actions were performed correctly, a corresponding inscription will appear on the screen, which will inform the owner that the phone is loaded exactly in safe mode.

After the final download, you need to perform any actions with standard applications, for example:

open the file manager;
see the amount of memory;
check the settings;
download system updates ();
use a standard internet browser;
record a video, take some photos, etc.

If Samsung does not reboot while doing this, there is a very high chance that incorrect work provoked precisely third party applications that do not belong to the official software. This method check gives about 90% of an accurate identification of the cause of the breakdown. In other cases, the fault should be looked for in the mechanical or hardware part.

Machine breakdowns

If the device worked adequately in safe mode, and when it went into a normal situation it resumed, the question remains what to do: the Samsung phone is constantly rebooting as before. You should start looking for mechanical damage with removable parts. mobile device. This could be a battery that has become deformed due to the destruction of an electrical element. By visual inspection, it is necessary to determine whether the thickness of the battery plate has increased, whether there are any extraneous bulges, dents or cracks.

If you have a standard household voltmeter available, it will not be superfluous to check the internal capacity of the battery. This procedure should be performed after the battery is fully charged, as a result, there may be 2 results:

the sensor will show 4.0-4.2 V - the battery is in good condition;
the value will be equal to 3.7 V - the battery is discharged.

As a result, the reason for rebooting the Samsung phone lies in low or insufficient power supply. In this case, the battery should be replaced with a new one.

Another reason for turning off or restarting the smartphone may be a small gap between the case back cover and a rechargeable battery.

note

If the phone turns off during a conversation, that is, when it is in an upright position, it is most likely caused by a loose contact between the battery and the electrical circuit.

You can check and fix this breakdown in an elementary way: lay a thin layer of paper between the battery and the back cover.

What to do if the Samsung phone is constantly rebooting, and the battery and its contacts are in good condition? The restart may be caused by mechanical damage to the internal parts of the mobile device due to a strong impact on a hard surface. As a result of the phone falling, the connecting or contact wires, thermo-soldering or any other component may peel off. May also crack motherboard, to which all the main elements of the gadget are soldered.

Will be useful

In this case, it is not recommended to repair the phone yourself. It must be handed over to the service center for complete diagnostics, since this procedure requires special equipment and a lot of experience.

Samsung Galaxy software crashes

If to eliminate mechanical problems an experienced technician or service center may be required, then
software problems can be easily solved at home. The main challenge is to pinpoint the exact cause, namely the application causing the system failure.

There are 3 main reasons for software-related breakdowns:

software conflict of the application with the official Android operating system;
incomplete or incompletely installed program update;
virus applications (spam bots) or malware software(trojans);

Let's consider each of the situations in more detail.

Installed software conflict

If after, bypassing the Play Market, the user found that the phone started to reboot, then the problem of the malfunction lies precisely in this software.

Remove the conflicting program. You must go to the section "Applications", find the problematic utility, and after opening the dialog box, press the button "Delete"... Having performed such a rather simple algorithm, take into account the fact that the remnants of the program may remain in the device's RAM.

You can finally eliminate the application through the standard service section. Recovery Mode:

Turn off your smartphone.
Press 3 keys at the same time: "Nutrition", "Home", "Volume +".
In the Recovery menu that opens, by pressing the volume buttons, go down to the item "Wipe cache partition" and start the cleaning procedure.
When finished, click "Reboot system now" to reboot the phone normally.

Incorrect application update

Frequent rebooting of the smartphone may affect the quality update of standard applications such as google music, maps, camera, standard browser, play market and so on. Newer software versions may not be compatible with the existing phone model.

It will be quite simple to identify such software: it will continuously require updates, over and over again. To solve the problem, follow the steps described below:

Through the settings menu, go to the section "Applications".
We turn over to "Systemic".
We find the required program.
Open its properties and press the following buttons: "Clear cache", "Erase data" and "Remove updates".

A smartphone or tablet can restart on its own for several reasons. Check the recommendations for each one in turn.

One-time software glitch

Don't worry if your device rarely reboots - once a week or two.

First, it may be due to by accidental pressing Power button. If you hold it down for a few seconds, the device
will reboot.

Secondly, over time, the battery wears out and can produce unstable voltage, especially when heavy loads... This is a natural process; in the future, it will simply need to be replaced.

UBANK application

Some devices (Galaxy A8 / A8 +, S8 / S8 +) had problems with the pre-installed UBANK app. If your device has such an application, please disable it.

If the device stops rebooting on its own, the problem is with the app. Try turning it on later if you need it.

If your device continues to reboot after turning off UBANK or you don't have such an app, go to the next recommendation.

If the device reboots once a week in strictly certain time, the "Automatic reboot" function may be enabled. Check it out: Menu - Settings - General settings - Reset - Auto restart must be turned off.

If auto reboot was turned off or it didn't work, go to the next recommendation.

Impact of installed applications

The device may restart due to applications that were installed after purchase. Some of the installed applications freezes and stops the operating system. To clear this "error" the device is rebooted.

Check to see if installed applications to operate the device by booting the device in Safe Mode. In this mode, all downloaded applications are disabled and only those that were installed at the factory work.

If the device is operating normally in safe mode, some downloaded application is to blame. Unfortunately, there is no way to determine which one, so we recommend uninstalling one at a time, starting with the last installed or updated. After uninstalling the application, observe the operation of the device. If the problem went away, it was the remote application. If it does not disappear - it was not in him, delete the following.

If your device still reboots in safe mode, skip to the next recommendation.
