Nokia 635. I enter my passcode and all I get is a white screen afterwards. No tiles and no way or cancelling out once I'm in. None of the refresh buttons work and I can't factory reset.
to hard reset using key combo, follow these steps:
:>Turn off your phone.
:>Hold volume-down.
:>Keep holding volume-down and press power button for about 3 seconds.
:>Let go of the power button, but keep holding the volume down until ! image/icon on the screen appears.
