When a phone starts restarting on its own, like this person’s in Quora, things start getting a bit more serious:

My Samsung Galaxy keeps restarting on its own. Every now and then it will just shut off on its own and switch on again. It is starting to get to the point where I can’t trust my own phone. Please help!

Reasons why a Samsung phone or tablet keeps restarting

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. Whether it’s a damaged battery, some loose connection, or a dent on the CPU, any kind of damage, big or small, could cause your Samsung to start restarting at random if it eve switeches on at all.

Many Samsung devices are designed to shut off automatically if they become too hot. If your device gets too hot, either because it’s running a very demanding app, or due to damage, it may shut down to protect itself. 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.

3. Loose battery

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. Apparently, what would happen was that the battery was coming a bit loose. This usually happens because of a bent connector or loose battery lid.

Yes, restart and reboot are two different things. Even though they are used interchangeably, they describe two different processes. A restart is the process during which a device shuts off mechanically and turns back on. This usually happens after the press of a button (like the restart button on a computer).

No, when a phone restarts the only thing that is deleted is the data on the RAM. The data on your ROM, cache, and storage are all safe. However, if a phone restarts while it is processing something the files in question could end up getting corrupted.
