Face ID Issues After iOS 27.0.1 Update.

You may try some of these steps, please check after each step...

1. Eye tracking relies heavily on the front-facing camera. Ensure the lens is clean and free from smudges or obstructions. Use a soft, lint-free cloth.
2. Ensure adequate lighting. Poor lighting can significantly impact eye-tracking performance.  
3. Sometimes assistive touch settings can interfere. Check your assistive touch settings within the accessibility menu.
4. Ensure your screen protector or case isn't obstructing the front-facing camera. See the poic below
   1. 
5. If you still need help, reset your Face ID, then set it up again. Go to Settings, tap Face ID & Passcode, then tap Reset Face ID. Next, tap Set up Face ID to set it up again. If Face ID isn't working on your iPhone or iPad Pro
6. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
   1. Restart the device. That's it. 
   2. Still not solved --> Force restart iPhone - Apple Support
7. Corporate iPhone Profile Check and Removal Guide
   1. Is this your corporate iPhone? Then please contact the system administrator of your corporate.
   2. If it is your device, in that case, do you have any profile installed by your corporate/organization/enterprise/School Management? 
   3. Erase the profile added by you If you have installed a profile on your own --> Install or remove configuration profiles on iPhone - Apple ...
   4. Please contact the system administrator of the organization who provided the profile to you 
8. Parts and service history
   1. With iPhone 12 models and later using iOS 15.2 and later, you can go to Settings > General > About to see the parts and service history of your iPhone and you can see if the camera has been replaced. If the repair was done using genuine Apple parts and processes, you will see "Genuine Apple Part" next to Camera.
   2. 
   3.  
   4. You will see an Unknown Part  message if the camera installation is incomplete or if the camera:
   5. Was replaced with a nongenuine camera
   6. Was already used or installed in another iPhone
   7. Isn't functioning as expected
   8. This message doesn't affect your ability to use your iPhone or access your camera. Learn more about iPhone parts and service history.
   9. If your iPhone's camera has been previously replaced, repaired, or serviced by an unauthorized service provider, it's worth noting that Apple may decline to provide service for your device. The decision to refuse service will depend on the specific components that were affected by the unauthorized service.
9. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
   1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
   2. You can return settings to their defaults without erasing your content.
   3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
   4. 
10. Make sure you have the latest updates installed.
    1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
    2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)

If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.

Is anyone else still having Face ID issues after the iOS 27.0.1 update

Update to iOS 27.2

Not every issue an individual encounters on their device can be attributed to an iOS update. iOS 27 or later may have coincided with what you are experiencing, but that does not mean the issue was triggered by iOS. Coincidence in timing is not, by itself, evidence of causation.

If the update itself were the root cause, then every device running that same version of iOS would exhibit the identical problem. In such a scenario, the forums would be flooded with countless posts reporting the same malfunction, creating an unmistakable wave of complaints that no one could possibly overlook.

The absence of such widespread reports strongly indicates that the issue is not a general, system-wide problem with iOS 27 or later, but rather something specific to the individual device, its configuration, installed apps, settings, hardware, or another interacting factor.

In short: iOS 27 or later may be a coincidence in timing, but there is no basis to conclude that iOS itself triggered the problem simply because the issue appeared after the update.

See what each update does: About iOS 27 Updates, About iOS 26 Updates, About iOS 18 Updates, About iOS 17 Updates, About iOS 16 Updates, About iOS 15 Updates, About iOS 14 Updates, About iOS 13 Updates, About iOS 12 Updates, and so on...

I wear glasses to use my iPhone 18 Pro Max. I’ve reset Face ID many times, also set up an alternative appearance. The issue still persists.

When I try to setup Face ID again whilst wearing my glasses, I’d get a pop up saying that Face ID is unavailable and to try later.

If I briefly remove my glasses, Face ID will work a lot better. I put my glasses back on, I’m faced with the same issue again. Face ID really struggles in Low Light/Dark situations.

Is there anything unusual about your glasses? Very large/small lenses? Heavy frames? Adaptive tint (light sensitive)? Polarised?

I have not seen any Face ID problems with my iPhone 15 PM or iPad, and 4 different pairs of glasses. It seems unlikely that a software issue would impact only one model of iPhone. However, your device exchange also seems to hint against it being a hardware problem.

I don’t have a Privacy Screen Protector. The case/screen protector that I use, doesn’t block the new Face ID Sensor under the screen.

I suggest remove all accessories and aftermarket screen protectors, test with a naked display to prove the point.

I know from what I’ve read, there’s people out there that aren’t experiencing issues with Face ID, on the iPhone 18 Pro/Pro Max. I just wonder how small the group of people is, that’s facing the same issues as me.

One of the basic rules is that even if the description sounds like the same problem, troubleshoot every one individually.

Can it be fixed in a future iOS 27 update?

Nobody here can answer that because we are all users like you. Apple does not read here apart from moderation to remove spam.

As you hopefully realize, polling is not allowed in the Apple Support Communities.

Secondly: “The case/screen protector that I use, doesn’t block the new Face ID Sensor under the screen.”

Are you certain? Do you realize the Face ID sensor on the iPhone 18 Pro Max is under the display in the top-left corner, and not in the Dynamic Island?

Hi

The glasses that I wear, are the same I wore when I had the iPhone 17 Pro Max and iPhone 16 Pro Max. I never had Face ID issues with either iPhone.

The issues still persist, even when a case/screen protector is removed and the screen is spotless.

Thanks

Barry :-)

Hi

I wasn’t polling. I was genuinely asking the question, to see if others had the same issue as myself.

I’m 100% sure. I know that the new Face ID Sensor has moved to the left of the screen. In certain lighting conditions I can see the location of the new Face ID Sensor, so that I know that it’s not blocked.

Thanks

Barry :-)

It is semantics but rather than

"Is anyone still seeing Face ID issues after the iOS 27.0.1 update?"

you should start with

"I am seeing Face ID issues after the iOS 27.0.1 update"

Keeps the mods happy.

I never had any issues until I updated to 27.0.1. I have a 16 pro max, nothing else changed except the software update.

I have reset the face ID, and tried shutting off "require attention for Face ID".

Nothing has helped, it is a bit frustrating.

Yes!

Please have you no got it sort out because same thing happen to me using 12pro no issue on till I update to ios27
