If the phone has not been dropped or suffered shock damage it may be worth trying the following:

  • Use the Power button and Volume Down button.
  • Press and hold those two buttons for a couple of seconds. Usually, it takes around 7 seconds or more before it works.
  • The phone will go off and reboot. You can release both buttons and wait for the phone to reboot and start operating again.

Good luck :)
