Delete some apps you don't use anymore?

There are a handful of phone recovery or anti-theft apps on the Google Play Store which can be a lifesaver in case you lose your phone or, even worse, it gets stolen. But many people might only realize that there are such apps AFTER it got lost or stolen. Then, it usually is too late and you have to face the ugly truth that the phone is gone for good.

Might be a power button issue, if it is pressed it will be restarting the phone. If it isn't pressed it might still be broken, a short near on inside the button might also be causing the issue. I recommend bringing the phone to a repair shop or trying your luck at opening it yourself, however if you don't feel comftoble doing that, you can also try to take out the battery and when you put it back in, if the phone turn on without you pressing anything, it is a very high chance that it's the battery. One way or the other, I recommend bring it to your local repair shop. Good luck!
