Mobile phone keeps restarting – How to Fix?

Android users may encounter one of the most frustrating problems when their device randomly reboots. A reboot loop occurs on your phone, and you don’t know what to do now.

What causes my phone to restart? You probably first think of this question if you find yourself in a situation where your phone won’t turn on. There are several reasons for looping:

  • Damaged hardware: A cracked screen can compromise your device’s internal components.
  • Third-party apps: Using third-party apps can corrupt your device’s software
  • High CPU frequency: This can be a serious motherboard issue

Below are some tips and tricks that may help you resolve this issue quickly. Getting your device diagnosed will help identify any issues.

How to fix an Android phone that keeps rebooting:

  1. Third-party applications
  2. Turn safe mode
  3. Turn recovery mode
  4. Hardware repairs
  5. Clear out the storage

Third-party apps

Your phone may restart because an app is running in the background. In some cases, restarting your device may be caused by poor-quality apps on the device. Uninstalling third-party apps may help. In this case, follow these steps.

  • Go to Settings > My Apps. Update all your apps.
  • Open Settings > More > Applications. It will show you any background apps you have running, so uninstall any third-party applications you see.
  • Try our tips below if this does not work.

Safe mode

You can find out if third-party apps are causing the problem by entering safe mode. This is probably why your device is working in safe mode.

In order to use safe mode, you must first power off your device and then hold the power button. Hold down the volume button while you see the make/model on your screen until Safe Mode appears in the bottom corner. Remove all third-party apps after exiting safe mode (holding the power button and pressing restart).

Recovery mode

If your device does not work in safe mode, the next step would be to reboot it in recovery mode. Data loss may occur if you do not back up your data using Android Data Extraction.

You can turn off the device by holding down the volume up, home button, and power button at the same time. You can see Android System Recovery on your screen when you release the power button when the phone vibrates. As soon as all buttons have been released, you can factory reset the device.

Wipe Cache data from your device by selecting Wipe Cache using the volume up button and then pressing the power button to confirm. You will then lose all cache data from your device. Click Reboot System now to exit recovery mode. If the device continues to reboot, you may need to enter recovery mode again.

If you restore your device to factory settings, you may resolve this issue. It is best to back up all the data that is currently on your device before wiping it. You can put your Android into recovery mode and select wipe data/factory reset using the steps above. The phone should now reboot normally after exiting recovery mode.

Hardware repair

The expert technicians will need to assess your Android if all the tips above do not resolve the problem.

It’s helpful to check your Samsung or other android mobile warranty before you visit any mobile repairs store. The mobile repair technicians may be able to help. They recommend checking your warranty to check where you purchased your device from. Samsung may cover repairs if you still have your warranty. If your warranty is over, this will cost you.

You can come to the mobile phone repair stores to assess your device if your warranty with Samsung gets expired. They would suggest initially running diagnostics on your phone to ensure the issue lies with your hardware. As part of their diagnostics assessment, skilled technicians will assess all components of your Samsung device to determine their functionality and determine the root cause of the unresponsiveness/restarting. Upon completion of the repair, they will provide you with a quote. 

Clear Out Your Storage

The storage space on your phone is limited. You may notice problems with your phone if you have less than 10% free storage-including random restarts.

It is possible to free up space on your phone in several ways. You can delete unused apps, clear the cache, and empty your internet downloads folder. Therefore, you should clear the storage on your phone.

Alternatively, you can expand your storage. Buy a microSD card if your phone accepts expandable media. You can also move data to a cloud provider, such as Google Drive or OneDrive.

With most phones, you can see how much storage space you have left and find larger files. For instance, Samsung devices:

  • Go to Settings
  • Device care
  • Storage
  • Tap the three vertical dots
  • Storage analysis
  • You can then delete duplicate, large, and unused files.


Following all these steps should prevent your phone from restarting unexpectedly. Now you can enjoy your phone without worrying that it will shut down at random. Now that it’s fixed take good care of your phone. Keep everything up-to-date, and delete anything that isn’t necessary.
