Vibration in my 640 LTE just stopped working all around the phone. It doesnt vibrate when ringing, nor when touching touch panel (the option is turned to ON, moreover, switched it to Off-On several times). Just do not want to do HR, but I am unable to start that vibro on my 640.
Did you try a soft reset? Press and hold the Power and Volume Down buttons until the phone vibrates (or just count 10 seconds then let go).
