Has this ever happened? Is there any chance it could happen? Just curious...

Not sure if you’re serious, but just in case.

Then you do a hard reset:

Press volume up
Press volume down
Press and hold side button until the Apple appears.

If that doesn’t fix it, you 1) put it into DFU mode or 2) Call/bring it to Apple.
