I've looked at some other threads, but I can't find any recent ones with my particular problem except one from 2009-10. Wanted to see if anyone else is having this problem (or if there's a thread/fix I've missed in my searches). I started having this problem the past week. Happened twice: suddenly the screen freezes and won't work, after rebooting the buttons are lit and alerts keep sounding off and I can take calls, but the screen is not working. I can see that the screen is on when I turn the lights off in the room, but no images show up. Each time it took MANY battery pulls before it booted up correctly again (i.e., with the screen operating) -- the second time it took several days of trying. Thsi seems different than other threads I've seen. This doesn't seem to be a battery problem -- I know the phone had plenty of juice the second time it happened. Also, not related to calls coming in. And the battery pull solution doesn't seem to work until the 100th try, which isn't very practical. I just uninstalled most of my apps (esp. the most recent) to see if memory was an issue or if any of the apps were messing with the phone. Anyone else out there is this problem?
