Smartphones from the Samsung Galaxy line, like any other mobile device, from time to time are subject to software and hardware failures. One such problem is the periodic or cyclic reboot of the phone. It can cause the user a lot of problems or even make it impossible to use the device normally. Let's take a look at why Samsung restarts itself and what to do in cases like this.
Possible reasons for restarting Android and how to fix them
There are several reasons leading to an unauthorized restart of Samsung:
- failure of the feeding element;
- mechanical damage to the gadget;
- ingress of moisture under the body of the device;
- breakage of any module on the board;
- glitch in software.
Let's try to figure out the reasons for the incorrect operation of the device on our own and, if possible, fix the problem on our own.
To start diagnosing the Samsung Galaxy A5 or other smartphone or Galaxy line, you should determine the type of problem. All faults can be conditionally divided into two types:
- Mechanical (hardware). They consist in damage (failure) of any element or module.
- Software. Caused by a malfunction of the installed software or operating system.
If the Samsung Galaxy phone restarts by itself, 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 doesn't restart on its own, it's safe to say that the glitch is rooted in Samsung software. Otherwise, you should look for a malfunction in its mechanical or hardware part.
Samsung Galaxy mechanical faults
If your phone keeps rebooting, remove the battery and visually inspect for bulges, dents, and other defects. Also, it will not be superfluous to check the voltage at the battery outputs using a tester. The permissible rate is 3.7 V when discharged and 4.2 V when fully charged. The reason for the self-rebooting of the Samsung Galaxy A3 or another model may lie in the underestimated voltage. In this case, the feeding element should be replaced with a new one. 
With long-term use of the mobile phone, a small backlash appears between the battery and the rear panel. And if in an upright position (for example, during a conversation) the phone is cut off, the reason may lie precisely in the insufficiently tight fit of the battery to the contacts of the device.
Mechanical damage to the device can lead to unstable operation and reboot of the Samsung Galaxy A5 as a result of a strong impact on a hard surface or ingress of moisture under its casing. And if something like this happened to your smartphone, it is better to take it to a service center, since not everyone can disassemble the mobile phone and determine the faulty element on their own.
Samsung Galaxy software crashes
Unlike mechanical damage, software problems are more likely to be fixed at home. The main thing is to understand correctly what exactly is the essence of the problem. The occurrence of software failures, as a result of which the Samsung phone reboots itself, usually results in:
- conflict of installed software;
- incorrect updating of system applications;
- exposure to malware.
Let's consider 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 the existing software. In this case, you need to get rid of such a utility:
After performing these actions, the system cache may contain "snapshots" of the erased application. You should also get rid of them. This can be done through the standard Android OS:
Incorrect update of system applications
Updates of preinstalled software (for example, Play Market programs, Google Play Services, Maps, etc.) can also cause unplanned restarts of Samsung. This is due to the fact that new versions of certain applications are not always suitable for a particular phone model.
If you suspect that the mobile phone restarts itself due to an incorrect update, you will need:
Exposure to malware
When downloading programs to Samsung Galaxy from third-party sites, there is a risk of picking up 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 to get rid of the crash, the only thing that remains is
A smartphone or tablet can restart on its own for several reasons. Check the recommendations for each of them 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 accidentally pressing the 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 under heavy loads. This is a natural process; in the future, you just need to replace it.
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 at a specific time, the Auto Reboot feature 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 installed after purchase. Some of the installed applications freezes and stops the operating system. To clear this "error" the device is rebooted.
Check if installed apps affect device operation 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 the device still reboots in safe mode, skip to the next recommendation.
In this article, we will try to give an extended answer to why the Samsung phone reboots itself during a conversation, typing, taking pictures, playing games or listening to music.
Most problems will require special skills, professional repair equipment and spare parts. Therefore, in such situations, we recommend contacting a service center in your city for help.
Reasons why Samsung phone restarts by itself
1. Software glitch
Samsung phones run Android or Windows Phone (select models). However, it is with the versions for Android that they most often face reboot problems during work.
If you find that after a recent kernel update (automatic or manual), problems with self-rebooting began to appear, then you should roll back the firmware to the previous version. You can do this yourself (the network is full of instructions on how to flash a phone), or you can turn to the pros for help.
Previous official firmware can always be found on the Samsung website in the corresponding section http://samsung-updates.com/device/.
After the manufacturer releases the next version of the firmware, you can update, because errors will surely be eliminated after numerous complaints from users from all over the world.
2. Problems with the battery or charging connector
This is the most common reason. To fix it, you may need the professional skills of repairmen in service centers.
First, you should check the battery for visible physical damage (swollen, oxidized contacts).
Next, let's see if there is any backlash between the contacts of the battery and the phone. The fact is that during a conversation, typing a message or a game, the phone is shaken, which can lead to a slight discrepancy in the point of contact and entail the phone disconnection with the possibility of self-rebooting.
It is not uncommon for the charging connector to become clogged or damaged by physical impact, resulting in a short circuit and causing the phone to malfunction.
3. Due to moisture getting under the Samsung phone case
After contact with the liquid, various elements of the phone could fail, which led to a spontaneous reboot of your Samsung.
In this case, diagnostics on professional repair equipment is necessary, because the effects of moisture can manifest themselves in different ways. This is the most difficult reason for the manifestation of one or another breakdown in any gadget to diagnose.
3. Memory overflow
Your Samsung phone requires not only physical memory (internal phone) space, but also RAM to work properly with Android or Windows Phone OS.
Lack of memory can lead to an abnormal termination of the gadget, followed by a reboot, in an attempt to boot normally.
Install the Smart Manager application, where you can see how much physical and virtual (RAM) memory is free. You can immediately clean / increase / free it.
4. Problems with installed applications
Everyone knows that there is practically no moderation on Google Play (Android application repository). All this leads to the emergence of unstable versions of applications, which are often infected with viruses.
Some applications may simply not be compatible with your phone model or firmware version. You install such an application, launch it, it seems to work, but it starts to overload the memory of your phone, or send incorrect signals to the OS. As a result, an emergency restart of the phone occurs.
Therefore, if you find that your Samsung phone restarts itself after installing an application or a set of applications, try uninstalling them and check the functionality of the gadget.
Other reasons for self-rebooting Samsung phones
In fact, there can be many reasons. We have listed the most common ones.
Often, in order to identify exactly what affects an arbitrary reboot, a full diagnostics of the phone is required.

Android phone constantly reboots
What to do if your Android phone keeps restarting
Unauthorized reboot of a smartphone on Android is usually associated with the unstable operation of an application on the device. There is one factor affecting the operation of a smartphone: if you download and install applications a lot and then uninstall and then do the same, then after a while you will notice that Android does not work so fast, and sometimes it starts to freeze. If you practice this, the best solution would be a smartphone.
It is best, of course, to download exactly those applications that have already been tested have good popularity and a high rating.
The question arises why the smartphone freezes or restarts after uninstalling applications. On Google Play, there is a very immense number of applications, some are "completely safe" - they do not affect the robot's device in any way, while others may conflict with similar ones or leave a bunch of garbage after being removed, thereby causing crashes and reboots.
If, after installing the application, the smartphone starts rebooting, this should alert you. It is better to uninstall such an application immediately and make sure that all system folders have also been removed from the device.

Android keeps rebooting - it's worth checking for viruses
One of the obvious options why the smartphone is rebooting is infecting the device with viruses and all kinds of malicious programs. In order to check your phone for viruses, use applications that analyze the entire system.

Disconnecting the SD card during spontaneous reboots of the Android device
If you notice that during any operation, your smartphone starts to turn off and on again. Disconnect the memory card on the device and try again the action that triggered the restart. If you find that the reason is the memory card. Transfer the data (photos, videos and other data) to a PC and format the card.
