It had happened a few day ago again, I don't know if it is because of an special app or what. but it won't vibrate at all, setting is set to vibrate always and SMS vibrate are on too, it doesn't vibrate even when I hold on monitor to change wallpaper, the other time it happened it fix by itself after 2-3 days, but this time it seems, it's not going to be fixed by itself Help please!
