Nokia Lumia 928 phone’s touch screen sometime freezes up. Without the touch capability, one can not even power down the phone to reboot it with the normal power down swipe.
Nokia provides a key combination to reboot the phone. Here are the steps:
- Push the power button to make sure that the phone is powered up.
- Push and hold both the power button and the Volume Down button for about 15 seconds. This reboots the phone.
- When phone reboots, the screen should work again
