There is an app I can't locate that is constantly making my phone vibrate. When it does, I immediately check the Notification Center. Nothing new there.

The vibrate could be a setting for an email application, or some other app.

One thing to note, I always have my app on silent/vibrate. I just unmuted it in the hopes that the sound will help me figure out what is going on.


How can I determine which app is sending rogue vibrations without any notification?
