Check Loose Battery

This is for very old Samsung phones that have removable batteries. If your Samsung phone has a removable battery, it’s likely that it’s the cause of the phone keeps restarting. Shake the phone to see if it restarts to determine if this is the issue.

Remove the phone’s back cover if you are certain that a loose battery is the source of the problem. Place a small piece of paper or something thin at the back-end of the battery to make it sit tightly.

Check Stuck Power Button

The Power button on your phone may become jammed at times. This can cause your phone to keep restarting. To loosen it, press the button several times. When you press the button, it should feel smooth.

If the button is completely stuck inside, use a tweezer or similar tool to pull it out. Also, check to see if any accessories, such as your phone case, are putting too much pressure on the button. This may also be the cause of the auto-restart problem.

If the power button on your Samsung Galaxy phone is stuck permanently, get it fixed from any Samsung service center.
