Wallpapers and notification sounds keep changing
hey guys, so my brothers got a droid 3, and since he lives in wyoming and i'm in NJ, i can't diagnose it in person...
but he keeps having his background wallpapers changing by themselves all the time. he's using stock backgrounds, not SD card images, and they always just randomly change. he said it'll change between two gray type ones over and over. pretty anoying.
he also says his ringtones keep changing by themselves and constantly changes his ringer, notification sounds, and now his email notification makes a sound even though he had that off.
anyone have any idea whats wrong? it's stock phone, no root or anything...thanks!!
