Everytime my S20 Ultra reaches 100% when charging, music starts to play and there is NO WAY to stop it, or at least, that I can find anyway. I've had to restart the phone every single time this has happened. Pushing the side power button does nothing, (To Turn Screen Off) there's no notifications to dismiss or anything. I can't find it in settings anywhere. If someone knows how to turn this off, please let me know.
