I wanted to test and set up a new vibration pattern in my ringtones. I went into Settings/Sounds/Ringtone/Vibration and picked Symphony. Then I went into Custom/Create new vibration. Here I tried some taps and presses. Nothing special. But when I used two fingers to create a vibration, my phone wouldn't stop vibrating until I closed out of settings and got back to the home screen. Can anyone try and duplicate this?
