Cyclic reboot of Samsung smartphone: causes and solution to the problem. Samsung Galaxy reboots itself Samsung galaxy s3 reboots itself

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

One-time software glitch

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

Firstly, this may be due to accidentally pressing the Power button. If you keep it pressed for a few seconds, the device
will reboot.

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

UBANK application

Some devices (Galaxy A8/A8+, S8/S8+) experienced problems with the pre-installed UBANK application. If you have such an application on your device, disable it.

If the device stops rebooting on its own, the problem is in the application. Try enabling it later if you need it.

If your device keeps rebooting after disabling UBANK or you don't have such an app, move on to the next recommendation.

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

If automatic reboot was turned off or this did not help, move on to the next recommendation.

Impact of installed applications

The device may restart due to applications that were installed after purchase. One of the installed applications freezes and stops the operating system. To reset this “error” the device reboots.

Check if they affect installed applications to operate the device by loading the device into safe mode. In this mode, all downloaded applications are disabled and only those that were installed at the factory work.

If the device works fine in Safe Mode, some downloaded app is to blame. Unfortunately, there is no way to determine which one exactly, so we recommend deleting one at a time, starting with the last installed or updated one. After uninstalling the application, monitor the device's operation. If the problem goes away, the problem was remote application. If it doesn’t disappear, it wasn’t his fault, delete the following.

If your device still restarts in Safe Mode, move on to the next recommendation.

If you have been the owner of a Galaxy S3 for a long time, then you might have encountered a strange “event” - the phone turns off and reboots for no apparent reason. Don't worry because you are not alone and Samsung is aware of such situations.

The message appeared on the Reddit website and currently has more than 150 comments written by members of the XDA-Developers community discussing the topic of the sudden death of the Galaxy S3.

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

At the time of his comment on the XDA forum, the discussion had already reached 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 have time to get root rights or install custom firmware, Samsung could still replace the device under warranty.

There was an assumption that the NAND was damaged and that was why the problem occurred. The worrying thing is that Samsung has already replaced boards of the same vintage, which raises a big question about the general problem with smartphones released 6 months ago or so.

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

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

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

Still, we don’t know the true extent 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 suffering from 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 en masse? Is the end near? Joke.

Seriously, we look forward to your comments and opinions on this topic. Have you encountered this problem? If yes, how did the official Samsung service help you?

Smartphones from the Samsung Galaxy line, like any other mobile devices, are subject to software and hardware failures from time to time. One such problem is the phone rebooting periodically or cyclically. It can cause the user a lot of problems or even make it impossible to use the device normally. Let's look at why Samsung restarts on its own and what to do in such cases.

Possible reasons for Android reboot and how to fix them

There are several reasons leading to unauthorized restart of Samsung:

failure of the power supply;
mechanical damage to the gadget;
moisture getting under the device body;
failure of any module on the board;
software failure.

We will try to independently understand the reasons for the incorrect operation of the device and, if possible, fix the problem on our own.

Diagnosis of the Samsung Galaxy A5 or other smartphone or Galaxy line should begin by determining the type of problem. All malfunctions can be divided into two types:

Mechanical (hardware). Consists of damage (failure) of any element or module.
Software. Caused by malfunction installed software or operating system.

If your Samsung Galaxy phone reboots on its own, the first thing to do is put the device into safe mode. In this state, only pre-installed applications are loaded on the smartphone, and third party utilities are temporarily disabled.

To activate Safe Mode on your Samsung Galaxy S6 Edge or other device, you must:

Use your smartphone in this mode for a while. If the phone does not reboot on its own, we can say with great confidence that the failure lies in Samsung software. Otherwise, the fault should be looked for in its mechanical or hardware part.

Mechanical faults of Samsung Galaxy

If your phone keeps rebooting, remove the battery and visually inspect it for bulges, dents, or other defects. It is also a good idea to check the voltage at the battery outputs using a tester. The permissible limit is 3.7 V in a discharged state and 4.2 V in a fully charged state. The reason for self-reboots of the Samsung Galaxy A3 or another model may lie in low voltage. In this case, the power element should be replaced with a new one.

When using a mobile phone for a long time between the battery and rear panel a small gap appears. And if the phone turns off in a vertical position (for example, during a conversation), the reason may lie precisely in the insufficiently tight fit of the battery to the contacts of the device.

Mechanical damage to the device as a result of a strong impact on a hard surface or moisture getting under its body can lead to unstable operation and reboot of the Samsung Galaxy A5. And if this happens to your smartphone, it is better to take it to a service center, since not everyone can disassemble a mobile phone and determine the faulty element on their own.

Samsung Galaxy software glitches

Unlike mechanical damage, software problems can most likely be eliminated at home. The main thing is to correctly understand what exactly the essence of the problem is. To the occurrence of software failures, as a result of which it reboots itself samsung phone, usually leads to:

conflict of installed software;
incorrect updating of system applications;
exposure to malware.

Let's look at each option in more detail.

Installed software conflict

If you notice that the Samsung Galaxy S3 or a device of another model began to reboot on its own after installing a program, most likely the problem lies in its conflict with existing software. In this case, you need to get rid of such a utility:

After performing these steps, “imprints” of the erased application may remain in the system cache. You should also get rid of them. This can be done through the standard Android OS:

Incorrect update of system applications

Updates to pre-installed software (for example, programs) can also cause unplanned restarts of Samsung. Play Market, Google Services Play, Maps, etc.). This is due to the fact that new versions of certain applications are not always suitable for specific model phone.

If you suspect that your mobile phone is rebooting itself due to an incorrect update, you will need:

Exposure to malware

When downloading programs from third-party sites to your Samsung Galaxy, there is a risk of catching a mobile virus that will force Android to involuntarily reboot. That is why it is recommended to download all software only from the Play Market or Samsung Apps.

To get rid of malware, you need to:

If none of the above methods helped get rid of the failure, the only thing left is

Samsung keeps rebooting

Despite the fact that Samsung Galaxy is the top model of the global brand, it, like many smartphones, can fail and begin to reboot constantly. Such a breakdown may be caused by a malfunction of any program or operating system on which this phone runs.

Problems can also be caused by a hardware failure, as a result of which the smartphone will constantly or periodically reboot.

note

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

What to do if your Samsung phone keeps rebooting? Let's look at several reasons for this malfunction and try to find ways to eliminate it.

Reasons for rebooting and how to fix them

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

broken 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;
core destruction.

We will try to independently identify several reasons for the phone’s malfunction 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 divided into 2 types:

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

note

If Samsung Galaxy constantly reboots in response to user actions (for example, pressing a finger on the screen sensor), it must be switched to safe operating mode. When launched in this way, the device is loaded only basic system applications.

All third party programs, set by the owner of the handset after activating the device, in this mode will be forcibly disabled.

Safe mode

Activating Safe Mode on all Samsung Galaxy phones is done in the same way. As an example, let's look at how this is done on the Galaxy S6 Edge.

To enter safe mode on this device necessary:

Hold down the power button and select the “Turn off” option. Wait until the smartphone screen goes completely dark and does not show any action.
If the model of the problematic gadget includes a removable battery, then the most in a simple way turn off the phone 100% will eject lithium battery and leave it in this position for a few seconds.
Return the battery to its place and turn on the Samsung Galaxy phone.

It is important to know

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

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

open file manager;
view the amount of memory;
check settings;
downloadSystemUpdates();
use a standard Internet browser;
record a video, take some photos, etc.

If Samsung does not reboot when performing such actions, there is a very high probability that the incorrect operation was caused by third party applications, which do not belong to the official software. This testing method provides about 90% 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, but when switching to normal mode the situation resumed, the question remains what to do: the Samsung phone constantly reboots as before. You should start looking for mechanical damage from removable parts mobile device. This may 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 foreign swellings, dents or cracks have appeared.

If you have a standard household voltmeter, it would be a good idea 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 the Samsung phone to reboot lies in low or insufficient power. In this case, the battery should be replaced with a new one.

Another reason why your smartphone turns off or restarts may be a small gap between the case back cover and a battery.

note

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

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

What to do if your Samsung phone constantly reboots, but the battery and its contacts are in good condition? The reason for the reboot may be mechanical damage to the internal parts of the mobile device due to a strong impact on a hard surface. As a result of falling the phone, connecting or contact wires, thermal soldering or any other component may become detached. The system board, to which all the main elements of the gadget are soldered, may also crack.

Will be useful

In this case, it is not recommended to repair the phone yourself. It must be taken to a service center for a full diagnosis, since this procedure requires special equipment and extensive experience.

Samsung Galaxy software glitches

If a mechanical problem may need to be resolved by an experienced technician or service center, then
Software problems can be easily resolved at home. The main task is to accurately determine the cause, namely the application due to which the system crash occurs.

There are 3 main causes of software-related failures:

software conflict between the application and the official one operating system Android;
incomplete or incompletely installed program update;
virus applications (spam bots) or malicious software(Trojans);

Let's look at each situation in more detail.

Installed software conflict

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

Remove the conflicting program. You need to go to the section "Applications", find the problematic utility, and after opening the dialog box, click the button "Delete". Having completed this fairly simple algorithm, take into account the fact that program remnants may remain in the device’s RAM.

You can permanently 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", which will reboot your phone normally.

Incorrect application update

Frequent rebooting of the smartphone can affect the quality update of standard applications, such as google music, maps, camera, standard browser, play market and so on. New versions of programs may not be suitable for your 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 we go to the section "Applications".
Scroll to "System".
Find the program you are looking for.
Open its properties and click the following buttons: "Clear cache", "Erase data" And "Uninstall updates".
