So last night I recieved the update, and instantly my phone locked up. Screen is unresponsive. I've pulled the batter 10 plus times now, and when it reboots it works for 20 seconds or so, then slowing locks up and becomes unresponsive. Late last night I pulled the memory card out just to see if this would help, and after 2 more times of locking up it started working again. Well this morning I woke and remembered my memory card was out. So i powered off the phone and put it back in. Phone worked fine. Now its early afternoon and my phone is locked up again and screen is unresponsive? Any suggestions?
