Before we look into how to fix the issue we have to understand why your Samsung phone or tablet keeps restarting in the first place. Let us see why that would happen:

1. Hardware damage

One of the possible reasons why a Samsung phone or tablet would keep restarting is that it has sustained damage to its hardware.

The best thing to do in those cases is to let your Samsung cool down and make sure to keep an eye on its temperature from time to time.

This happens on phones with a removable battery. Old Android devices were notorious for suddenly restarting. Sometimes they would shut off and never turn back on.
