Help! Received update OTA for 4.04 and my phone is now glitching. It crashes, screen freezes-I have to remove battery to reboot because I can't even power off after freeze. Phone quality is bad, no smooth scrolling, lags, battery icon error, 'not connected to network' error... On and on. This was a beautiful phone and now it's horrible. I don't have it rooted, it's a UK version and I'm using an ATT sim card. Can anyone help me get it working as well as it did prior to Jul 25? Thanks
