How to disable part of the screen
I've cracked my nexus 4
and now the bottom part of thr screen(i.e. The nav bar+ up to the backspace button or rather the right corner) doesn't work, so the phone is pretry much unusuable at the moment. Is there any way of disabling that part(like a Black bar that does nothing) so I can use the phone for a few days until I get my hands on a replacement? Oh, and BTW, how hard is the screen chamging procedure? I'm tempted to do it myself as I've broke spart phones in The past.
Thank you very much in advance!
