Smartphones from the Samsung Galaxy line, like any other mobile device, are subject to software and hardware failures from time to time. One of these problems is the periodic or cyclic rebooting of the phone. It can cause the user a lot of problems or even make normal use of the device impossible. Let’s look at why Samsung itself restarts and what to do in such cases.
Possible reasons for restarting Android and how to fix them
There are several reasons leading to an unauthorized restart of Samsung:
- failure of the supply element;
- mechanical damage to the gadget;
- moisture under the body of the apparatus;
- breakdown of any module on the board;
- software crash.
Let’s try to figure out the causes of the device’s malfunctioning on our own and, if possible, fix the problem on our own.
To start diagnosing a Samsung Galaxy A5 or other smartphone or Galaxy line, you should determine the type of problem. All malfunctions can be conditionally divided into two types:
- Mechanical (hardware). They consist in damage (failure) of any element or module.
- Software. Due to a malfunction in the installed software or operating system.
If the Samsung Galaxy phone restarts by itself, the first thing to do is put the device in safe mode. In this state, only pre-installed applications are downloaded 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:
- Turn off the problem gadget and wait for the completion of all programs.
- If the unit has a removable battery, remove it for a few minutes and then reinsert it.
- Turn on Samsung. When the company logo appears on the display, hold down the mechanical Volume Down key. After performing these steps, the corresponding inscription should be displayed on the screen.
Touch your smartphone in this mode for a while. If the phone does not restart on its own, it can be stated with great confidence that the failure lies in the Samsung software. Otherwise, look for the malfunction in its mechanical or hardware part.
Mechanical faults Samsung Galaxy
If the phone constantly restarts, remove the battery from it and visually inspect for swelling, dents and other defects. Also, it will not be superfluous to check the voltage at the battery outputs using a tester. The permissible norm is 3.7 V in the discharged state and 4.2 V in fully charged. The reason for self-rebooting Samsung Galaxy A3 or another model may be covered in low voltage. In this case, the power supply should be replaced with a new one.
During prolonged use of the mobile phone, a small backlash appears between the battery and the rear panel. And if in a vertical position (for example, during a conversation) the phone is cut down, the reason may lie precisely in the insufficiently tight fit of the battery to the contacts of the device.

Unstable operation and rebooting of the Samsung Galaxy A5 can result in mechanical damage to the device as a result of a strong blow to a hard surface or moisture under its body. And if this happened to your smartphone, it is better to take it to a service center, since not everyone can do it on their own to disassemble the mobile phone and determine the faulty element.
Samsung Galaxy crashes
Unlike mechanical damage, software problems are more likely to be fixed at home. The main thing is to correctly understand what exactly is the essence of the problem. The occurrence of software failures, as a result of which the Samsung phone reboots on its own, usually results in:
- conflict of installed software;
- incorrect updating of system applications;
- exposure to malware.
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 any 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:
- Through the settings of the smartphone, enter the “Applications” section.
- Find the desired program and call its properties.
- In the window that opens, click “Delete.”
After performing these steps, “snapshots” of the erased application may remain in the system cache. They should also be disposed of. This can be done through the recovery mode standard for the Android OS recovery mode:
- Turn off your phone completely.
- Hold simultaneously the mechanical power, home and volume up buttons.
- Once in the Recovery area, use the volume rocker to select wipe cache partition and start cleaning.
- Allow the smartphone to reboot normally by clicking reboot system now.
Incorrect system application updates
Unplanned restarts of Samsung can also be caused by updates to preinstalled software (for example, Play Market programs, Google Play services, Maps, etc.). This is due to the fact that new versions of certain applications do not always fit a specific phone model.
If you suspect that the mobile phone is rebooting itself due to an incorrect update, you will need:
- Get into the “Applications” section.
- In the “System” tab, find the program that causes the Android to malfunction.
- Open its properties and click “Clear cache”, “Erase data” and “Delete updates” one by one.
When downloading programs from third-party sites to the Samsung Galaxy, there is a risk of catching a mobile virus that will force Android to restart unintentionally. That is why it is recommended to download all software only from the Play Market or Samsung Apps.
To get rid of malware, you must:
- Download the mobile antivirus software to the device. It is recommended to use Kaspersky IS, Dr. Web or Avast.
- Run scan.
- If a threat is detected, block it.
If none of the above methods helped to get rid of the failure, the only thing left is to make a complete reset. This can be done through the standard Samsung menu. The required procedure can be found in the Archiving and Reset section. If a cyclic reboot occurs when the phone boots, you can perform a hard reset through the Recovery environment.
