Face ID Stopped working 2-3 days after IOS update 18.4.1

Follow these steps, testing after each step:

• Face ID not working.
• Software Update.
• Turn iPhone on or off.
• Force Restart iPhone.

If that didn’t work, then it could be a hardware issue.

According to Apple:

Using diagnostics available in iOS 14.6 or later, Apple has detected an issue with your TrueDepth camera that might cause it to not function as expected. The TrueDepth camera contains lasers, which might be disabled for safety reasons if the device malfunctions or is damaged. This won't prevent you from using your iPhone or iPad, but until your iPhone or iPad is updated or serviced, you might not be able to use Face ID, Animoji, Memoji, and some other features that use the front camera.

As a result, I recommend service.

Service Checklist:

• iPhone service pricing.
• Check AppleCare Coverage.
• Get your iPhone ready for service.

"Face ID Stopped working 2-3 days after IOS update 18.4.1: I have used my iPhone 13 since purchase in January 2023 successfully without any problems. Updated IOS to 18.4.1 a few days ago which went without any problems. Face ID worked as before the update. However yesterday morning Face ID stopped working. Reseting or later using 'Set Up Face ID' it would only let me get to the'Position your face within the frame'. It then consistently tells me 'Your face is out of vie'" and to 'Position Your Face Within the Frame. Over and over. I have recovered via a backup without a change to this dilemma."

I was having the same exact problem. I opened the camera to see if it was working correctly. That’s all it took to fix it. (Idk if it’s what was wrong, but the last time I used the camera I set it to slow-mo.)

When Face ID doesn't work, it usually indicates an issue with the TrueDepth Camera, either a software issue or something obstructing it, or a hardware issue. Please first troubleshoot with these two Support Articles.

If Face ID isn't working on your iPhone or iPad Pro - Apple Support

If an alert says Face ID has an issue on your iPhone or iPad Pro - Apple Support

If those don't help and the issue persists, this would be indicative of a hardware issue. It's also possible it was already starting to fail before and then the update caused additional stress on it to fail. As a result, I suggest you make a reservation at your nearest Apple Store Genius Bar or Apple Authorized Service Provider.

exact same problem and solution. Opened the camera and turned it to the FT camera. It was blurry for 5 seconds and then resolved. After that Face ID started working again
