Face ID stopped working on my iPhone after iOS 17 update

Updated my iPhone 11 to.ios 17.01 last night. Since then, my face id won't work. I get error messages or it says face id not available. I thought I could reset face ID but it's not letting me do that either

. Rebooting the phone didn't help. Everything was working fine until the ios 17 update finished installing.

Here are some of the solutions mentioned in this guide: How to Fix Face ID Not Working on iPhone After iOS 17 Update


First of all you should try to restart your device( different way ) : go to settings > General > their shutdown, wait for a few minutes then power it on. Make sure your notch area is clean and clear. you said you already reset face id then skip this step. If nothing else works then according to them erase all content from your phone hope this step will fix the issue. For the steps please refer to the guide I mentioned.

My issue since iOS 17.0.0 update and now have the iOS 17.0.2 and still happens but its random time every other times I restart the phone and in after using the phone for a while and I plug my phone to the charger and I try to wake the phone and use face ID to log in and it doesn’t want to unlock my phone and i have to type the password to log in and to remedy this issue I have to restart the phone and it works fine again! I mean its iOS 17 not iOS 2.0 this kind of bug should not be happening come on Apple!

Happens to me too. I've been experiencing problems with FaceID ever since I updated to iOS 17.

To make things worse, once I've installed 17.0.2 a whole set of much graver problems started to appear; my iPhone (12 Pro) would randomly initiate a restart, but will stay stuck in a loop and never reach the lock screen again (it just blinks the apple logo on and off). At that point, the only option I discovered I had is to connect it to my Mac and "Update" it. And here's the fun part: This also doesn't work if I try to do it immediately, I need to let the iPhone stay "bricked" for a good couple of hours before I can successfully update it using my Mac and regain access to it.


I noticed that the random restarts happen sometime after "Face ID" fails working and I get the error messages described by @sajam.


ps: ..the icing on the cake: the iPhone bricked when I was abroad, so no access to credit cards, boarding passes etc. Thank you apple!

Both Apple senior advisor and in store rep told me it’s not a known issue. Wonder if anyone else has had their phone checked in a store. They told me I had a hardware problem even though I never had any problem with FaceID until iOS17. They said it’s coincidence other people are having the same issue. Literally a nurse at my doctors appointment today said the same thing happened to her. Apple literally said FaceID isn’t that important. Lol

And magically, after not doing anything when I came in here to say thank you for the link, I was able to get in seamlessly with my Face ID whereas when I tried to get in here before to post it kept saying I wasn’t recognized (as did everything else I had set up to use Face ID as my passcode). That said; thank you for the link, I definitely will use it. I had that same thought after I posted. I was like I doubt that’ll go anywhere because I don’t think anyone at apple actually monitors the community user forum.


But again, thank you for your reply!

That could very well be, but I can't say that the dirt was obvious. One can easily get some oil from fingers on the lens. The software should, of course, be able to correct for that, so I think they did screw up big, but my "fix" got me back to normal for multiple hours now, and I will take care for now not to touch the lens, and if I do wipe it.
