Mobile Power Button Missing / Not Working — Screen On & Off
Ways to wake and lock a phone when the power button is missing or broken, and when to get a hardware repair.
Before you start
Double-tap-to-wake or lift-to-wake (Settings → Display / Gestures, if your phone has it)
Scheduled power on/off (Settings → Accessibility on many Android phones)
Accessibility menu or a screen-off app as a temporary lock option
Check whether the button is stuck or physically damaged before opening the phone

Safety
Repair and flashing can erase data or damage a device if done incorrectly. Back up first, use files that match your exact model, and proceed at your own risk.
