I cracked the screen on my 920 about 2 months after getting it, and have finally gotten around to replacing the screen. I did the same on my wife's 920 and didn't have any issues. With this one, the first time the digitizer simply wouldn't work. Now it will work sometimes, but require a reboot when it decides not to. Also, the lights on the three soft buttons do not turn on at all anymore, nor does double tap to wake. Do I have a bum digitizer? I've restated the cable a few times for the digitizer and haven't been able to get it working back to normal. Thanks for any tips.
