10 Fixes for Unable to Activate Face ID on This iPhone Issue

Now that we know what can cause the “Unable to activate FaceID on this iPhone” error to happen let’s explore its solutions. In this section, we will explore ten different methods to fix this issue. You can read their steps and follow what best suits you.

Fix 1. Force Restart your iPhone

The first method that you should try to fix the iPhone’s Face ID error is force restart. A simple restart is not enough to fix the issue, and you need to do a force restart. This technique has been helpful for many users. However, it’s better to give it a try yourself.

Since the face ID is only available on iPhone X and later versions, you can follow the below instructions to force restart the iPhone:

Step 1: Tap the Volume Up button and then release it.

Step 2: Tap the Volume Down button and then release it.

Step 3: Hold the Power button for a few seconds until you see the Apple logo on the screen.

However, if a force restart doesn’t fix the issue, you can go for the next method.

Fix 2. Ensure the TrueDepth Camera Is Not Covered

When setting up Face ID, ensure that the TrueDepth camera on your iPhone is not blocked or covered. This camera captures intricate details of your face so that any blockage can cause issues. Here’s how to ensure it’s clear:

• Check Your Phone Case: Verify that your phone case doesn’t cover the camera area. Use a compatible case if needed.
• Clean the Camera Area: Wipe away any dust, dirt, or fingerprints near the camera with a soft, lint-free cloth.
• Avoid Finger Placement: Ensure your fingers or hands don’t block the camera area. They shouldn’t be located at the top of your screen.
• Reposition Your Phone: Hold your iPhone at the right angle and distance during Face ID setup. It allows the camera to capture your face accurately.

We hope it helped you fix the issue. Otherwise, you can try the next way.

Fix 3. Remove Your Sunglasses or Mask

When setting up Face ID or trying to unlock your iPhone, you should consider your accessories. If you’re wearing sunglasses, it’s a good idea to take them off. Sunglasses can block the TrueDepth camera’s view. They make it difficult for Face ID to work correctly.

Similarly, if you’re wearing a mask that covers a significant portion of your face, remove it. By doing this, you increase the chances of Face ID successfully recognizing your face and granting access to your iPhone.
