My phone freezes before I can unlock it

[Android Central Question]

When I swipe the screen before I can type in my password, my phone freezes on my lock screen before the screen turns off, and it keeps happening. The screen also keeps turning itself on a couple of seconds after I turn it off. There is no way for me to turn off the phone completely and the battery is not removable.

Try Safe Mode.

If the same, it could be faulty hardware or software, or a bad battery.
