Default Random vibrate on boot.

So I'm aware of the haptic-like vibration when a phone is rebooted/booting up/shutting down which I know is normal.

However after it has loaded into the main screen, my phone vibrates (sorta a haptic-feedback vibration).

I have no clue what is calling this vibration. Initially I thought it was caused by my phone being on silent and it's notifying me that the phone is on vibration mode but I turned up the volume and I'm still getting it.

I noticed it was vibrating at around the same time my wifi toggle is enabled through the quick settings in the notification drop down. However, again I troubleshooted by switching off my wifi, reboot phone but I still get the vibrate.

I used logcat to see whether I could find out whether an app is calling a vibration but I can't really make any sense from it. I notice around 20 seconds into boot up there's a vibrator service showing up.

Sorry for the noobish reply, but what does this do?

I don't think it's a phone error but more so an app I installed (ever since towelroot was released) lol.

Then again, its not bothering me too much but at the same time I kinda want to know where it's originating from.

Tick that option to notify you whenever application not responding occur to trouble shoot it

yes ive noticed this too, ive used towelroot too but not sure if it was there before. i thought it was just related to the wifi switching on like you said. be interesting to find out what causes it.
