OK. I dropped my phone last Sunday at church. It was in my leather pouch and not a far fall. Nothing broke but now when I am driving or in a meeting and the phone rings, the ringtone is all garbled and won't stop until I actually hit the home button to cancel out of it. It rings as normal when not in Assist mode. I tried to uninstall Assist but I could only uninstall the latest update since Assist came pre-installed on my phone. What would cause the phone to ring abnormally when the Assist is active.
