My power button works, but only to lock the phone and restarting the phone is impossible cause I can't long press the power button. Anyone else encountered this problem and anyway to solve it? This problem occurs randomly and sometimes the reboot menu shows up, sometimes it doesn't.
hold the power button for 10 seconds. The phone will turn off. turn it on to see if it works or not. If not, do a factory reset. That'ss all you can do.
