My phone updated itself to ICS over wifi yesterday (rather than via Kies through a PC). After the phone restarted my contacts app no longer works. It hangs for a while and then I get a "Contacts is not responding" error message. Has anyone else had this happen to them? Anyone know of a resolution? The only thing Samsung help desk could advise is a reset back to factory settings. If I do that I will lose all of my data/photo's/apps etc but I did regularly back up my phone so is it as simple as resetting the phone and then restoring all my apps/photo's/data etc? Any help or advice would be gratefully received.
