As of last night when phone is in Vibrate Mode, I am no longer getting a vibration for my notifications. It behaves as if it's on silent. I changed nothing and have rechecked all settings and everything is as it was.. I know the vibration feature is in fact working bc it still vibrates when I press the volume down rocker, notifying me that it's in vibrate mode....I've tried turning it on and off as well as a battery pull. Don't know what else to do. This is horrible..Can anyone recommend any suggestions or fixes??
