How can I log/discover what is triggering vibrations?

[BWB8771]

I have GS3/4.2 and I am well-acquainted with my apps and their individual notufication settings.

I've ruled-out Facebook as a/the culprit.

Is there an app/utility that can trap or log calls made to the device's notifier functions?

If you look in your status bar at the top it will tell you what apps have notifications, meaning if you heard a vibration it was probably for one of the things in the status bar.

I had to go through every setting but I found one that had a vibration setting. Sorry don't remember where, just open setting and start at the top.

If you phone is vibrating randomly it could be an app crashing. It's typically 1 long vibrate, followed by 2 short. Normally you would see a force close dialog too but sometimes strange things can happen.
