That is definitely unusual performance for the Galaxy S III jlove76! This is not a known issue with this device. If the problem becomes more persistent, I recommend running the device in safe mode to rule out third party app conflict. http://tiny.cc/fhs6iw

What if you can't get your phone to open in safe mode? My phone screen locked up I took the battery out to try to reboot it, now my phone wont boot up, stops on screen that says "4GLTE"
