I have 0 alarms turned on and I even changed all my existing alarm sounds. It seems to happen when im on call all night. I can’t recall if it happened when I wasn’t on call but I have to hang up in order to reset my phone and get rid of the sound. I tried turning down all volume but it doesn’t change the existing volume of the alarm sound. When I tried to play the same sound through the clock app alarms, it got louder so I was forced to restart again. I don’t want to restart every morning and it’s a weird problem, please help.
