Ever since I updated to ICS my nexus has been "buggy". But now out of nowhere everything starts force closing. It started with gmail force closing then every other app started (even the ones that can't be uninstalled). I don't have a lot of downloaded apps btw. Then this started popping up and also and error message about the launcher. I can't make calls or send text messages because everything keeps closing. I've tried factory resetting it, hand resetting/rebooting and nothing. Even after I pressed erase everything, everything is still there. Help!?
