So here's the story...
My iPhone X was working just fine on 13.4.x. Then a couple weeks ago I updated to 13.5.1 because of the rumored FaceID w/Mask unlock. Everything seemed to be working fine––but I think I got so used to typing passcodes I didn't notice if FaceID ever worked after the update.
When I finally realized something was wrong with FaceID, I did the usual: soft reset, FaceID reset, and then finally, factory reset. Nothing worked, and once I reset FaceID, I could never "Set up Face ID" again. Every attempt left me with the "move the phone higher/lower" bug.
Since then, I've also updated to 13.6 with no change in FaceID. After reading more than a few pages on the web, I've got the following diagnosis:
iPhone X FaceID checklist:
- Proximity sensor/AutoBrightness OK
- Animoji OK
- Selfie camera portrait-mode does NOT work, “move farther away” msg, no background blur
- Rear camera portrait mode OK
"Set up Face ID"
- shows "position your face within the frame" or "move iPhone a little higher/lower"
Can someone help me determine if this is 1) a software bug or 2) a fatal hardware failure that coincidentally emerged within days of upgrading to 13.5.1?
