galaxy a70 keeps rebooting by itselfFixing a phone that keeps rebooting by itself is a bit tricky. It’s because this kind of problem can be due to a hardware issue, especially if  your phone has recently been dropped or got wet. However, it can also be due to a minor firmware issue that affects the overall performance of your device. It seems like some owners of the Samsung Galaxy A70 have encountered a problem like this.

We have encountered similar issues in the past and many of those cases have been fixed by doing some basic troubleshooting procedures. That’s what we’re going to do in this post. I will share with you the solutions we’ve been using in fixing a smartphone like Samsung A70 restarting or rebooting by itself.

Troubleshooting a Samsung Galaxy A70 that keeps rebooting

Performance issues, while they’re pretty annoying, aren’t really that serious.  You only need to do a few troubleshooting procedures to make your phone work perfectly again. That’s what we’re going to do here, we will consider all possibilities and then rule them out one after another until we can fix your phone and prevent it from rebooting by itself.

Connect the phone to its charger and see if the Samsung Galaxy A70 still reboots

First off, we need to know if this is a problem with the hardware, specifically the battery. We all know that among all hardware components, the battery is the first to deteriorate, especially if you’re an intensive user. When the battery starts to fail, it might begin with random, infrequent reboots. Then the frequency goes up until you can no longer be able to use your phone properly because of the said problem.

So, the first thing you have to do is connect your phone to its charger and allow it to charge for a few minutes before using it like you always do. Your device will normally heat up fast if you use it while charging but if the problem disappears while your phone is connected to the charger, then it can be a sign of a battery issue. But nevertheless, it’s best to continue troubleshooting.

Run your Samsung Galaxy A70 phone in safe mode

By running your phone in safe mode, you are temporarily disabling all third-party applications. It is important to do this procedure because it will tell you immediately if this problem is caused by one of the apps you installed. This is how to run your phone in safe mode:

  1. Press and hold the Power key until options show.
  2. Tap and hold the Power off option until it changes into Safe Mode.
  3. Tap the Safe mode icon to restart your device.
  4. Once the reboot is successful, you should see ‘Safe mode’ at the lower-left corner of the screen.

Once your phone has successfully booted up in safe mode, try to use the phone and see if it still keeps rebooting by itself. If the problem is fixed, then here’s what you need to do next:

  1. Restart your phone normal to boot into standard mode.
  2. Remember the apps you installed about the time when the phone starts to reboot by itself.
  3. Once you already have an app in mind, swipe down from the top of the screen to pull the notification panel down.
  4. Tap the Settings icon on the upper-right corner.
  5. Scroll to and then tap Apps.
  6. Find and tap suspected app.
  7. Tap Storage.
  8. Touch Clear data and tap OK to confirm.
  9. Tap the back key once and then touch Uninstall.
  10. Confirm that you want to remove the app from your phone.

However, if your phone still reboots by itself even in safe mode, then move on to the next solution.
