Vibrate mode was working fine then a couple weeks ago it just stopped working, i.e.. incoming calls will not vibrate the phone. The "phone vibrate" mode is checked in the "Settings -> Sounds & Display settings". I've power cycled the phone but no luck. Is there another option perhaps that needs to be turned on/off? Even when I turn the volume off with just the vibrate mode initiated the phone will not vibrate. I thought about a "Hard Reset" but maybe someone here has a better solution?
thx
