(thanks really much - worked on my 13 pro max)


Turns out, the problem was with content restrictions. I had content and privacy restrictions enabled, which were blocking Face ID from working properly. Here's how I fixed it:


  1. Go to Settings > Screen Time.
  2. Tap on Content & Privacy Restrictions.
  3. Enter your Screen Time passcode if prompted.
  4. Tap on Passcode Changes and set it to Allow.
  5. After turning off the restriction, Face ID started working again. So, before diving into software or hardware fixes, l'd recommend checking your this settings first.

I know this may be an inconvenient fix but may be the solution, and if it’s not very sorry for the inconvenience 😅


Has anyone tried factory resetting their iPhone? I don’t remember if that wipes your apps or anything but I believe if you use iCloud for backup you can restore all your stuff shortly after resetting the phone. Sometimes factory reset is the end all be all tried solution if turning settings/phone off and on again doesn’t work
