My avant (metro) is rebooting every two bloody minutes after I start up twitter, or download an app update or so much as touch the screen to log on. It freezes and will stay frozen for up to 15 minutes when I am scrolling a web page in Chrome. I can't reboot without pulling the battery. I don't know if it's possible for a system app to get corrupted ? I haven't downloaded any new apps in over 3 weeks and this all started sunday. Was there a system update that happened I wasn't aware of ? I get error messages like Touchwiz has crashed. Is it worth doing a factory reset ? One other thing, I am not rooted. I'm a wimp. Never had the guts to try it. Just know I would brick it.
