My Xperia Z power on only when i connect to the charger and i press power button until it vibrate one time.
I can't power on without charger. Also when i have to lock/unlock the device (when it is on), power button doesen't work.
Volume + button doesen't work when device is on.
But i can use it to navigate through the recovery or to connect my phone to pc in fastboot mode.
I can't use power button to confirm all in recovery mode.
What can I do? Any solution?
