fix Face ID not working on iPhone after iOS update

Last evening, iOS 17.4 was released while I was at work. I thought I would update my iPhone before bed, and I assumed it would be ready to use with the latest software by morning. I followed through with my plan, and when I woke up, my iPhone 14 had already been updated. However, to my surprise, Face ID was not working on my iPhone when I tried to unlock it. Although I didn’t pay attention at that time, I unlocked it using my password and carried on. Later, when I needed to make a call, Face ID failed again, and I had to unlock it using my password once more. This happened repeatedly throughout the day, and after the third or fourth time, I began to suspect that there might be an issue with Face ID not working on my iPhone properly ever since I updated to iOS 17.4.

After researching a bit, I found I wasn’t alone. Many people were facing similar problems. If you’re among those experiencing the Face ID not working after updating to iOS 17.4, you’ve come to the right place. In this article, I’ll explain why Face ID not working on iPhones after the iOS update and provide fifteen working fixes, along with a bonus fix. Additionally, if, despite following all troubleshooting steps, your iPhone’s Face ID still isn’t working, I’ll also share alternative methods for unlocking your iPhone.

Why Face ID Not Working on iPhone After iOS Update

Before trying to fix Face ID not working on iPhone after iOS update, it’s important to figure out why it’s not working. Knowing why will help us find out what exactly is wrong with Face ID and why your iPhone isn’t unlocking with it. Once we know the problem, we can find the right solution to fix it.

1. If you’ve recently installed a new iOS update on your iPhone, it will restart immediately after the update. Then if you try to unlock your iPhone using Face ID and it doesn’t open, leading you to believe that Face ID is not working just after the iOS update, let me clarify: you will need to enter your passcode to unlock your iPhone because Face ID may not work initially. Once you enter the passcode and unlock the iPhone, you will be able to use Face ID for subsequent unlocks until you restart your iPhone again.

And yes, if the problem persists, you should look at the next cause.

2. The TrueDepth camera is dirty, covered, or malfunctioning, causing Face ID not to work on the iPhone.

3. It’s possible that your camera angle might not be right, or you may not have held your phone properly, causing your face to move out of the frame, thus stopping your iPhone from unlocking with Face ID.

4. You may not have unlocked your iPhone for 48 hours.

5. You may have passed five unsuccessful attempts to unlock your iPhone five times with Face ID or Passcode.

6. Maximal lighting conditions, such as very bright sunlight directly hitting the TrueDepth camera (you are standing opposite to the sun) can affect Face ID’s not to work. Additionally, wearing sunglasses, hats, or other accessories that make your face unclear can also interfere with Face ID.

7. It is less likely that the iOS update itself directly physically damages your iPhone’s TrueDepth camera. You may have accidentally bumped the camera part of your iPhone against a hard object, dropped it in water, or experienced any other physical damage either caused by you or someone else before, during, or after the update.

8. Significant changes in your appearance (beard or a new hairstyle) can confuse Face ID and cause you not to unlock your iPhone.

9. You probably toggle off the Face ID, or the update might have changed any Face ID settings.

  2. Scroll down and tap on Face ID & Passcode.

Do Not Cover Your Face or TrueDepth Camera

Covering the TrueDepth camera can indeed be the culprit behind Face ID not working on iPhones after an iOS update. Your iPhone’s TrueDepth camera is a set of sensors located in the notch or dynamic island of your iPhone, depending on the model you own. Blocking the camera while unlocking your iPhone can disrupt Face ID to scan your face, leading to imperfect functionality accurately. Therefore, it’s essential to ensure that the area around the TrueDepth camera is clean.

Moreover, an iOS update might not directly cause the camera to be covered, but if you’ve recently updated your iOS and then experienced difficulties unlocking your iPhone with Face ID, you might suspect the update as the cause. In such cases, there are two potential scenarios: either the issue lies elsewhere, requiring troubleshooting, or secondly, the TrueDepth camera might be blocked up by something, such as tiny dust particles, a cracked or scratched screen protector, or stains. In these situations, it’s recommended to remove the screen protector and clean the screen above the sensors with a microfiber cloth to restore Face ID functionality.

It’s important to note that any object that blocks the TrueDepth camera, whether it’s a damaged screen protector or anything else, is not the sole reason Face ID might not work. Your facial appearance, such as wearing or not wearing glasses, wearing a face mask, or covering your face with anything, could also cause Face ID to function properly.

Hold Your iPhone Correctly

Holding your iPhone at the right angle is crucial for accurate face recognition. Holding it too far away or too close can cause the camera to struggle to capture your face properly. To unlock your iPhone, hold it either in portrait or landscape orientation. However, this feature is only supported on iPhone 13 and newer models with iOS 16 or later. If you’re using an iPhone model older than iPhone 13, stick to portrait mode. Also, ensure your iPhone is within arm’s length, ideally between 10 to 20 inches or 25 to 50 cm.

Turn Off and On Face ID

Turning off the Face ID and turning it on again can sometimes resolve the issue with the Face ID not working on iPhone. Follow the below steps to do so.

When you use Face ID on your iPhone, there’s a setting called ‘Require Attention’ that checks if you’re looking at the phone with your eyes open. If there’s a problem with Face ID after an update, turning off Require Attention for Face ID might help it unlock your phone even if you’re not watching your phone closely.

  3. Enter the iPhone passcode.
