Face ID not working after update. Move iphone higher/lower and then Face out of view.

Hello theedumargarcia,

Thanks for reaching out to Apple Support Communities. Resetting Face ID was a good start, but if you're continuing to have issues, we have a few additional suggestions to help rule out other causes. The following article provides the best steps to resolve this issue: If Face ID isn't working on your iPhone or iPad Pro - Apple Support

"1) Check for updates

Update your iPhone or iPad to the latest version of iOS or iPadOS. And make sure that your iPhone or iPad model supports Face ID.

2) Check your Face ID settings

To check your Face ID settings, go to Settings, then tap Face ID & Passcode. Make sure that Face ID is set up and that the features you're trying to use Face ID with are turned on.

3) Check that nothing is covering the TrueDepth camera

Remove anything that might be covering the TrueDepth camera like dirt, a case, or a screen protector.

If you're using an iPad in landscape orientation, make sure that your finger or palm isn't covering the TrueDepth camera. If it is, an alert might appear at the top of the screen that says "Camera covered" with an arrow pointing at the TrueDepth camera.

4) Make sure that your face isn't blocked

Make sure that your eyes, nose, and mouth are fully visible to the TrueDepth camera. By default, Face ID doesn't work if anything is covering your mouth and nose. If you're wearing a face mask and have already set up Face ID with a mask,* make sure that your eyes aren't blocked. You might need to hold your iPhone higher if you're wearing a face mask. If you wear a face mask too high or too close to your eyes, your iPhone might not unlock.

Face ID works with many sunglasses, though Face ID with a mask isn't designed to work with sunglasses. If you're wearing sunglasses designed to block certain types of light, then your sunglasses might be blocking the infrared light used by the TrueDepth camera. Try using Face ID without your sunglasses.

* You can use Face ID with a mask on iPhone 12 and later using iOS 15.4 and later.

5) Make sure that you're facing the TrueDepth camera

Face ID works on iPhone only when it's in portrait orientation and you're facing the TrueDepth camera. On iPad, you can use Face ID when your iPad is in any orientation.

The TrueDepth camera has a similar range of view as when you take a selfie or make a FaceTime call. Whether your iPhone or iPad is lying on a surface or you're holding it in a natural position, make sure that your iPhone or iPad is an arm's length or closer (10-20 inches) from your face.

6) Restart your device

Restart your iPhone or iPad and enter your passcode. Then try using Face ID again.

7) Add an alternate appearance 

For most users, Face ID will continuously learn as they change. If you have an appearance that can look vastly different, you can set up an alternate appearance so Face ID still recognizes you.

To set up an alternate appearance:

1. Go to Settings, then tap Face ID & Passcode. If asked, enter your passcode.
2. Tap Set Up an Alternate Appearance.
3. Look straight into your iPhone or iPad and place your face inside the frame.
4. Gently move your head to complete the circle. If you're unable to move your head, tap Accessibility Options.
5. When you finish the first Face ID scan, tap Continue.
6. Gently move your head to complete the circle for a second time.
7. When Face ID setup is complete, tap Done."
