I’ve searched a bunch of sites and forums and haven’t found an answer to this. Maybe someone here can help.

My iPhone X (OS 13.3) keeps adjusting the screen brightness on its own. It’ll go to extremes- lowest or highest brightness- without me doing anything. I have auto brightness, True Tone, and night shift all turned off.

It even happens while I’m using it. I can see the brightness meter going down or up completely on its own. It’s fucking weird.

Any ideas?
