After upgrading to ICS I have been having some issues with my phone; Bluetooth needs to be cleared of data each time I want to pair a device, ringers and alerts don't sound, and the most recent and debilitating- the phone restarted twice by itself and now the sleep/wake button is unresponsive. Has anyone else experienced these issues? I've done factory resets once or twice since upgrading to ICS and it's really getting on my nerves. -is it time to call it quits and just bring the phone to a service center? -any insight into rolling back to gingerbread (on a Mac preferably) Thanks guys!
