Top 7 Ways to Fix iPhone Face ID Not Working

The Apple’s Face ID is a really cool feature that contributes in revolutionizing smartphone security and authentication. With Face ID, activities such as unlocking your iPhone, applications, and authorizing payment have become convenient. However, just like the iPhone battery optimization, Face ID occasionally faces some glitches that cause it not to function correctly. In this guide, we shall cover seven (7) different ways to revive your iPhone’s Face ID should it stop working.

Without further ado, let’s get right into the solutions.

1. Check iPhone’s Camera

Face ID uses the TrueDepth camera system situated on the iPhone’s display notch to map your face and carry out authentication checks before unlocking your device or apps. If the TrueDepth camera is blocked (either partially or fully), Face ID might not work. You should check that no particles or debris are covering your iPhone’s notch. You can wipe the camera with a clean microfiber cloth and relaunch Face ID to check if that works.

If you have a case attached to your iPhone, ensure that it isn’t covering the notch or obstructing the camera system at the top of the display. Some screen protectors can also block the iPhone’s TrueDepth camera from functioning correctly. If Face ID stopped working right after attaching a screen protector to your phone’s display, you should remove it.

2. Change iPhone’s Orientation

The Face ID designed to work only when your iPhone is in the same orientation as your face. That means Face ID won’t work when your face is upright, but your iPhone is held in landscape orientation (i.e., holding your phone sideways). Likewise, when your face is sideways (say you’re lying in bed) and your iPhone is in its natural portrait position/orientation, Face ID might not be able to authenticate your face. (Trust me, I tried it and it doesn’t work.)

Adjust your face to be properly aligned with your iPhone and try Face ID again.

3. Move Closer to Your Device

Apple says Face ID works the best if the distance between your face and iPhone is 10-20 inches (25-50 centimeters). If Face ID isn’t authenticating you, try bringing your iPhone closer to your face. The closer, the better. But hey, not too close.

4. Check If Face ID Is Enabled

If you are trying to use Face ID for certain applications or services, but it isn’t working, you should check that Face ID is enabled for the affected apps/services. Here’s how to check the Face ID settings.

Step 1: Launch the iPhone’s Settings menu.

Step 2: Tap ‘Face ID & Passcode’ and enter your phone’s passcode to proceed.

5. Setup Alternative Appearance

Sometimes, Face ID isn’t faulty, but you think it isn’t. The problem is that Face ID has refused to recognize you with a face-covering gear on. If you work at a job where you are required to wear protective gear (e.g., facial mask, infrared-blocking goggles, etc.), Face ID might not work while you have them on. Interestingly, Apple lets you set up an alternative appearance that’s entirely different from the primary identity that Face ID recognizes.

With an alternate appearance, Face ID will recognize you with your work gear and while at home in regular clothing. Here’s how to set it up.

Step 1: Launch the Settings menu and select ‘Face ID & Passcode’ option. Enter your iPhone’s passcode to proceed.

While this means you will have to set up the feature from scratch, it should help rid any issue causing your phone’s Face ID not to work. Follow the steps below to reset Face ID on your iPhone.
