Ever since the ICS update the security and screen lock screen keeps popping up on me. I can be in the middle of a text, browsing the inet or on the phone. I had a phone pin set. I removed that trying to see if that would help.... nada. Shut down reboot....nada... trying to avoid restore of phone as the phone Calender doesn't sync with Gmail.... not bothered by redownloading apps....just hoping there is a cure that doesn't involve me writing down a massive amount of appts.....please HELP!!!!
