I got my Samsung Galaxy S2 (android 4.0.4) for a few days now and i realized there's something wrong with the vibration. When I get whatsapp message or Viber, facebook, or email notification the phone won't vibrate!
When I receive a call or standard text the phone does vibrate. I did a hard reset but the problem still remains. What do I do?
In settings, it is ticked sounds and vibrate.
