Why my phone wont turn off

[Android Central Question]

I have a a51 and it wont turn off.I tried to reset it but that worked only for a few hours and then the phone won t shut down. The screen only turns off when im talking to someone on the phone. It does not turn off when I press the power button or when I double press the screen.

That may need repairer attention, though you could perhaps try Safe Mode, and flood-cleaning the Power button with alcohol. I doubt that either of those would fix it, however.

Welcome to Android Central! Are you trying to power the phone completely off, or just put the screen to sleep?
