What I'm trying to find out is if any 3rd party app you installed is causing this problem. Glitches can come in all shapes and sizes (and sounds), so Safe Mode is an easy way to narrow things down. If the problem goes away in Safe Mode, then something you installed is probably causing the issue. If the problem persists in Safe Mode, then it's probably an issue with the firmware or hardware.
