Since updating to iOs 5.1.1 this afternoon my iphone 4 is vibrating for no reason, like it vibrates, i pick it up to see if i received a notification or an email but theres nothing, is anyone having the same issue ?
lol. Does that app have different vibration pattern?
Joke aside. My 4S has vibration issue too. If i get a SMS or whatsapp message, it would keep vibrating and freeze for 20 seconds. If i turn on the sound then it would play first half of the tone then the whole tone.
