Had it about a month, never dropped it or damaged it in any way, then about an hour ago I noticed the phone was no longer vibrating when I was touching the screen. Doesn't vibrate when I'm typing a txt message or at any other time when touching the screen. Rang my phone from the house phone and found out that it was no longer vibrating when ringing either. All options are set correctly, "vibrate when typing", "haptic feedback", the lot. It just will not vibrate no matter what I do. As a hail mary I even switched it on and off a couple of times but still nothing. Any ideas fellas?
