“Face ID not available” after updating iPhone XS Max to 18.2

MetaSteelers Said:

“Face ID not available” after updating iPhone XS Max to 18.2: I updated my dad’s iPhone recently and 1 day after he said his Face ID wasn’t working. One week after the phone is now telling me to send it to service the Face ID with a technician. I saw multiple people complaining about this issue but I haven’t seen anything about the message suggesting to take the phone to repair"

Seeing a Technician for a Face ID Issue:

I. Provide a Screenshot:

The iPhone would not "demand" that you to get it seviced. So, provide a screenshot of this message. IMPORTANT: Block out personal information (i.e. time and names) by blocking it with red-colored rectangles and such, through use of the Photos app. Go here: Take a Screenshot on iPhone - Apple Support

II. Troubleshooting Face ID:

There are know stand alone updates for Face ID that I am aware of.

A. Overview these two links:

• If an Alert Says Face ID has been Disabled on your iPhone or iPad Pro - Apple Support
• If Face ID isn't Working on your iPhone or iPad Pro - Apple Support

B. Also, Report this to Apple:

Do your Part: Provide Apple with feedback on this, letting them know about this issue.  Apple may not get back to you directly, but the more feedback they receive on this, the more they will know what is occurring, and what bug fixes to include in updates to come. Apple will know nothing of this, if you don't report it to them.

1. Go Here: Feedback - iPhone - Apple
2. Select: "Bug Report" for the "Feedback Type"
3. Comment: that this all began after installing an update. Include the URL of this thread.
4. Proceed from there as necessary

Might be from being so old. My dad’s iPhone 12 Pro Max face id stopped working and later I found out it’s becuase of dust. But becuase the phone is so old and iOS 18 might be its last update the xs gets might be from being so old
