Face ID stopped working on my iPhone after iOS 17 update

Je viens d’avoir Apple à nouveau.

je ne sais pas s’il m’a dit ça pour couper la conversation rapidement ou non mais voici :

• apple confirme le défaut et une mise à jour doit corriger le pb
• en attendant il peut être bien de réinstaller iOS 17.1 via un Mac ou iTunes si PC (+ restauration sauvegarde)

je vous invite TOUS à téléphoner car c’est le nombre d’appels qui va prioriser le correctif. Le diagnostic qu’ils ont effectué sur mon téléphone ne présente aucune anomalie hardware. Téléphonez, expliquez calmement que ça marche parfaitement parfois et que c’est depuis iOS 17.01

Bonne soirée !

Same issue but easy fix. I tried resetting face id initially, rebooted, scratched my head…. Kept getting message “face id is not available now try later.”

OK I then wiped the area over the camera lens just to make sure there were no smudges on the glass. BINGO! All good with face id after that. 👍

Hey All I went into my Face ID settings and disabled the unlock screen Face ID and the locked phone reopened with passcode and went back to Face ID settings enable unlock with Face ID again and it seems to have cleared the issue

Hi I had this problem earlier in week and resolved it.

l went into my Face ID settings and disabled the unlock screen Face ID

then locked my phone then reopened with passcode and went back to Face ID settings enable unlock with Face ID again and it seems to have cleared the issue

My FaceID stopped working as well. However I just figured out that I had turned on the screen distance thing and that uses the FaceID to tell if I’m putting my phone too close. I turned that off and my normal FaceID worked again.

I've been having this problem for a few weeks and was able to fix it. SETTINGS>FACEID & PASSCODE turn OFF iTunes & AppStore. ***Power phone off***. Once the phone is powered back on, repeat and turn ON iTunes & AppStore. ***Power phone off***. Once the phone is powered back on it should work. Hope this helps.

Same happened to me. Face ID did not work after updated to 17.2.1. I did the start re-start several times and I was still unable to reset Face ID as the camera did not seem to recognize my face. I cleaned the camera carefully and did another re-start, this time the camera recognized my face after reset face id. It is now working.

Thank you! All I did was remove the cover, cleaned the camera lens, and it worked. And I wear glasses too.

My experience:

After getting the Face ID not working symptom around the time of the upgrade to 17.1 I too thought it was related to the software update breaking something.

After several weeks of frustration, the diagnostics (previously clear) on my 3rd visit to Genius bar diagnosed a hardware issue.

Apple found that replacing the True Depth camera did not resolve the issue. They eventually diagnosed a faulty logic board. Under the (paid-for) repair they eventually provided a replacement phone.

I'm disappointed in the phone malfunctioning in this way after just 25 months, and also in the way the diagnostics and repair part of the support process worked. To say nothing of the ££ Apple has charged me.

However, I can confirm the replacement device works just fine under now iOS 17.3.

So, if you experience intermittent Face ID working, and in particular the 'Lower your camera' message on the Face ID re-enrolment dialogue then it is possible you may have the same root cause of a faulty logic board.

Thanks so much for everyone’s help and advice. In my particular situation, I removed the screen protector and I was able to reset Face ID and it is functioning properly again.

Some not so good news. I spoke to an Apple Senior Advisor EMEIA for an hour on the phone. The issue has been logged and they have ONE other report of it in the entire company. Right now, the directive is to have the devices repaired physically as they have no other information to go on. Estimated repair is €700!! They will not take one or two peoples experience on board. There must be a large volume of complaints for them to believe you and take action. They advised as many people as possible to feed back to them, and even then, they may not do anything. Estimated repair is €700!! So please, everyone, send your experience to Product Feedback - Apple

I had the same issue and I even reset my entire iPhone and Face ID still didn’t work. My best friend said it may be my screen protector because they develop a film on them after awhile around the camera lens. Sure enough I removed my screen protector and my Face ID started working. Not sure if that’s what’s wrong with anyone else’s but I thought I would share it since it helped me.

I lost face id after 17 update. As suggested by another user, i went to general to shut down phone. I waited a minute or so and rebooted. Went to set up face id snd it worked this time. Go figure?

Mine also stopped working. I tried resetting it and kept getting an error and restarted my phone 3x. Finally, I was able to get it to work once I went to a very brightly lit room. I don’t normally have to do that, but was able to reset the Face ID and then it started working again for my apps. Weird issue.

I cleaned my lens and it's working again for the time being. Thanks for the tips!
