Larry's Samsung Galaxy S5 is rebooting all the time. What can he do? Leo says his mobile phone company wants him to upgrade, but before he does, he should perform a backup and reset. It will erase the phone and reset it to the day he bought it. He should make sure he backs up his photos and videos before he does it. For that, Leo recommends Google Photos. That will likely solve the problem. If it doesn't, then it's time to get a new phone.
