The flashlight on my lock screen does not work. Neither does the camera. What's up w that?

If they do not work pressing (for 1 second) those icons, try a "forced" restart of your 12 mini, using these instructions:--> Force restart iPhone – Apple Support

You do know the buttons have to be pushed hard, right? Just tapping them won’t work. If that is not the issue you could try restarting, resetting or restoring the phone. Failing that, you’d need to get Apple to take a look.

My pleasure
