Not so long ago, Apple released the latest iOS 15.6 update without new features, but with some bug fixes – the version of the operating system is most likely the latest, since iOS 16 is waiting for us next. But Apple has traditionally failed to release a perfect update that would do nothing but please the existing users: for example, on the forums, people began to complain that after installing iOS 15.6 on the iPhone, Face ID stopped working . Let’s figure out what causes the problem with face recognition and how you can fix it.
Face ID not working after update
Fortunately, the problem is not widespread. The MacRumors forum has a dedicated thread for it, as does Reddit . Problems with Face ID have affected different smartphones: iPhone 11, 11 Pro, iPhone 12 Pro Max , iPhone 12 mini and even iPhone 13 Pro Max. After installing the update, Face ID does not recognize the face. Fortunately, if you did not drop your iPhone on the floor or in water before installing the update, the problem is most likely systemic, so the most working way is to reset Face ID settings.
- Open Settings.
- Select Face ID & Passcode.
- At the bottom of the page, click Reset Face ID.
Then set up Face ID again by scanning your face. Usually this method works, but sometimes when you reconfigure, a message may appear, and when you try to reconfigure the scanner, it gives the error “Face ID is not available. Try setting up Face ID later.” In this case, try turning off the passcode in the Face ID settings – this item is located at the bottom of the page.
What to do if Face ID is not working
Forum users admitted that one of the causes of the malfunction may be a dirty Face ID module or problems with auto-brightness on a smartphone. To do this, try wiping the scanner, turning on auto-brightness in the settings, and turning off the lights in the room. If the backlight level does not change, then try to fix it as follows.
- Disable Night Shift, but spoils the color reproduction and can even affect the backlight. It’s better if you also disable True Tone.
- Turn off auto-brightness and restart your iPhone, then turn it on again and test the sensor in the dark.
- Do a factory reset: go to settings, select General, then Reset.
Also, forum users have found a working way: turn off the iPhone , wait until the screen turns completely off and turn it on again after 10 seconds. True, some report that the reboot needs to be repeated several times: they don’t specify how many, but they say it helps.

How to set up Face ID on iPhone
Another way is to reset iPhone using a PC program. Of course, you can do it right through the iOS settings, but users recommend doing it through a program on your computer – try PassFab iPhone Unlocker. It’s free and resets your iPhone without entering your Apple ID password.
- Download and install PassFab Unlocker from this link .
- Connect iPhone to PC and click “Trust this computer”.
- Run the program and click “Start”, then “Next”.
- The program will offer to update your version of iOS, if it is available: click “Download”.
- After installing the update, a screen will appear where the program will prompt you to start the reset. Click Start Remove.
- After the reset is completed, you will need to reconfigure the system when you start your smartphone. It is important not to skip the Face ID setting: activate it – everything should work.
Also note that Face ID may simply not work due to bright lighting: when exposed to direct sunlight, for example, on the street, Face ID does not recognize the user’s face, so you just need to choose another place. Not everyone knows about this, so they often complain about the inaccessibility of face unlock.
One user noticed that after installing the update, Face ID was unable to scan the face, so he simply increased the screen brightness on the phone to the maximum. A similar problem occurs in beta versions of iOS 16, but it will probably help with iOS 15 as well.
