I have encountering this problem from so long but previously it was just for few minutes. But from yesterday it has stopped from vibrating while calls or pressing any key. I checked properly in setting whether it is turned on or not. But it was on . I also tried restarting it for a few times. But nothing happened. I also sent this in feedback to mi. But there was no response. Please provide any solution if avilable. Neither navigation keys nor dial pad and calls are vibrating.
