Why is my techno P9 do switch off itself and on itself back????

[Android Central Question]

What is the causes and solution.

It could be a bad battery. It would have to go into the shop for diagnosis and repair. The repair would probably cost more than the tablet, though.

Welcome to Android Central! Are you saying the phone completely powers down, and then powers on again? Or is it just the screen that's turning off and on?
