Hello, dear.

Is it that it can't be used for the first few seconds when it is just turned on, or it can't be used all the time? If you can't use this security software and desktop within a few seconds of booting, or you can upgrade to the latest version to try, if the problem is still not solved, you can apply for after-sales Oh, after-sales will be tested by the pro, and then solve the problem for the pro, I hope the reply will help you, and I wish you an early solution to the problem.

I'm having the same problem with my Nubia Z7M N phone: the power button is out of order, the volume"One key fails,"The + key is normal. Click Settings on System Update and select in the top right corner"Reco Ery mode"Select"Restart your phone to confirm, after entering the interface (press the volume key to select.)"Restart your phone", press the power button to confirm), and the problem of the power button failure was solved after the phone was restarted.

Another method: set a timer to turn on and off (the interval should be short, otherwise it will be difficult to wait).

If you can't use it all the time, go to the after-sales service point to take a look.

Mine is the same, I took it apart and looked at the power button is broken, the power button has been closed, just go to the place where the phone is repaired and change the power button.

When the power is turned on, press and hold the power and volume at the same time to enter R mode, and then find the factory reset.
