For sure, I've had similar problems before. Here's a rapid guide I found useful:
- restart your cell phone.
- check your settings - make sure Pulse on Ring or Pulse on Quiet are enabled.
- check for a software upgrade - at times issues can be resolved with an upgrade.
- if none of these help, take your mobile phone to a repair shop as your vibration engine may well be damaged.
