How to Fix After iOS 17 Update, Face ID Not Working Issue on iPhone

So, here are some fixes that will help you resolve FaceID not working issue on iOS 17:

Fix 1: Ensure the Screen Guard Is Not Scratched

In order to protect their screens from scratches, Apple users generally apply tempered guards or screen protectors. As the screen protectors wear out, they may become dirty and scratched, preventing Face ID from working properly. Face ID sensors are usually cut out precisely in iPhone screen guards, so there shouldn’t be any problems.

To protect the sensors, you might have to replace the screen protector often if you use an all-screen tempered glass screen protector. If you’re experiencing Face ID issues on your iPhone, check your screen guard and replace it if it’s scratched.

Fix 2: Set Up Face ID Again

Face ID

You should try setting up Face ID again if experiencing Face ID problems. There may be some issues with your iPhone with the Face ID data. If this is the case, a fresh Face ID setup should immediately fix the problem. Here are the steps to set up Face ID on iPhone in iOS 17.

Go to the Settings app on your iPhone.
Go to the Face ID & Passcode section.
To access the settings, enter your iPhone Passcode.
You will need to follow the onscreen instructions to set up Face ID.
It should now be possible to use your Face ID.

Fix 3: Keep the Face ID Sensors Clean

You probably use your iPhone to answer all calls that come to your number if it is your primary device. When you talk on the phone for hours with the phone stuck to your face, the sensors get covered in grime and oil. Face ID misbehaves due to problems with face recognition when this occurs.

It’s a good idea to clean the display notch or Dynamic Island if there is visible grime. If you want to avoid scratches on your smartphone’s display, use a soft microfiber cloth.

Fix 4: Check if the Face ID Sensor is Damaged

Face ID might be damaged if your iPhone is experiencing problems after being knocked or dropped. For confirmation that your iPhone has physical damage, you should have it checked by a specialist.

Taking your cell phone to a local repair shop for this is not a good idea. Your warranty will be voided, as the sensors and display itself may be further damaged. There is no point in saving money at the expense of hassle and risk. Getting your iPhone checked only at Apple’s authorized service centers would be best.

Fix 5: Set Up An Alternate Appearance

iPhones might not be able to detect changes in your face if you wear glasses or follow No Shave November. It is, therefore, imperative that you set up an alternate appearance to enable Face ID. Here’s how to do it.

Go to Settings on your iPhone.
Select Face ID & Passcode from the menu.
You will need to enter your iPhone Passcode to access these settings.
Toggle on Set Up an Alternative Appearance under the Appearance tab.
To set it up, follow the onscreen instructions.

Fix 6: Ensure Your Face is Visible Completely

For Face ID to work properly, your face must be visible. With new iPhones, Face ID unlocks can also be used with masks. When using older devices, it is necessary to remove anything on your face, including a veil, mask, or accessories. Using the steps below, you can set up Face ID to recognize you with a mask on in newer models.

Go to Settings on your iPhone.
Navigate now to Face ID & Passcode.
To access the settings, enter your iPhone Passcode.
Toggle on Face ID with a Mask at the bottom of the page.
To set it up, follow the onscreen prompts.

Fix 7: Reset Face ID

It might be necessary to reset the Face ID and set it up again if the above methods do not work. In this case, you will need to set up Face ID again after removing the previous one. Here’s how to reset the Face ID on your iPhone.

Go to Settings on your iPhone.
Navigate now to Face ID & Passcode.
To access the settings, enter your iPhone Passcode.
To reset your Face ID, click the Reset button.
Click on Set up Face ID.
You will need to follow the onscreen prompts to set up Face ID.
Now, your Face ID should work.

Fix 8: Reset All Settings

You won’t lose any data when you reset all settings, including photos, videos, apps, and music. It removes all iPhone settings, including Wi-Fi, Face ID, Passwords, and keyboard settings. Here’s how to reset all iPhone settings.

Go to Settings on your iPhone.
Click on General.
On the next page, scroll down to the bottom and click on Transfer or Reset iPhone.
In the context menu, click Reset.
Next, tap Reset All Settings.
Once the process is complete, re-activate your Face ID.
Now, your Face ID should work correctly.

Fix 9: Restore Your iPhone

If you restore your device, all your data and media files will be erased, but it may be the last resort in resolving the issue. You can try it if you need to.

Go to Settings > General > Transfer or Reset your iPhone.
Select ‘Erase All Content and Settings’.
