so my motorola android screen decided randomly not to work today. it was working fine this morning when i took it off of the charger, but when i checked it at work, the screen was illuminated but black. initially, i thought the battery had died, until my little green notification light went off. i have taken the battery out and put it back in a couple of times as this has happened twice before and that fixed the problem, but it's still not working, and everything else about the phone seems to be operating normally. i read a couple of other threads about doing a restore on the phone, but i don't know how to do that. the phone's been dropped a couple of times but not recently. any suggestions? is my phone toast? thanks! tiffany.
