Although Samsung devices offer smooth user experience and you will very rarely face an issue with your device, occasionally something may go wrong. One problem that you might face when using a Samsung device is that it keeps on restarting. This article will explain the possible reasons as to why your device is restarting constantly and then provide you with the solutions to repair your device.

Why Is Your Samsung Phone Restarting?

There is a wide range of reasons as to why your device might be restarting. However, the most common reasons are listed below and explain why they might be causing your device to restart.

  • Overheating: If you have been using your phone exhaustively for a long period or have been carrying out intense tasks, such as gaming, it might be overheating. As a safety mechanism, your device will power off to close all processes and prevent the phone to overheat, which might cause damage.
  • Unstable applications: Although Google attempts to remove unstable and unreliable apps from the Play Store, you might have installed an unstable application that is causing your Android device to restart.
  • System resources: Commonly, when a phone's storage is full, it might restart to help clear some of the "junk" stored on the device. Although it is unlikely that full storage keeps on forcing your device to restart, a full cache or near 100% CPU usage is more likely.
  • Malware: You may have downloaded a file or application from the internet on your device that contained malicious software.
  • Firmware: The firmware on your device could be faulty and may contain bugs. This will cause your device to restart because it is not able to function correctly.
  • Physical issues: Physical aspects of the device failed due to either wear and tear or damage to the device. Your power button could be stuck or faulty, therefore it is randomly causing your Samsung phone to restart.

These are some of the common reasons which could be an explanation as to why your Samsung phone is restarting however there could be other issues with your device.
