A couple of days ago the three buttons at the bottom of the screen (back, home and apps running) were flickering like they were being touched. This obviously made the phone unusable as the screen tried to keep up with the buttons order's. I shut the phone down and restarted it only to find that all three buttons are now unresponsive.
Tried a full factory reset, turning on glove mode and restarting in safe mode. All to no effect.
Any ideas?
