Since the 4.1JB update on my phone (Droid Razr), every so often my phone will start vibrating. It does a short-long-short-long-short-long pattern about every 3 1/2 minutes. There are no notifications, and I have not established that pattern for any app/notifier. It continues even if I change from vibrate to ringer. The only way to stop it is to reboot the phone. Once rebooted, it seems to be fine for a day, maybe more. Then it'll start again, necessitating a reboot.
Other than continually rebooting (which I know can be helpful, but it isn't always an ideal time to do it), any ideas on a solution?
