Ensure That There Is No Obstruction over the TrueDepth Camera

If you cannot activate the Face ID on iOS, then the obvious thing you must check is for any obstruction, like the case of the device or the screen protector covering the TrueDepth camera of the phone.

Also, see if there is any dirt or debris over the camera. All these things block the camera from recognizing the face. You need to ensure the clarity of the camera so that it can facilitate the working of the Face ID easily, and you are no anymore unable to activate the Face ID on this iPhone.

Ensure That Your Face is Clearly Visible

Ensure that the face is fully uncovered and bare in front of the camera. The mouth, nose, eyes, and other face details must be clearly visible to the camera.

Also, ensure that you are not wearing any sunglasses or a face mask. Standing in a properly lit place will also help.

Put the Phone in the Portrait Angle

The most important thing is the orientation or angle of the camera. You must try putting the camera in portrait mode and then putting it in front of your face.

Make sure that there is an ample amount of light falling on the face so that the Face ID gets to scan and remember the features properly.

Keep the iPhone Away at a Maximum of an Arm’s Length

If you stand at a longer distance from the camera, then it will fail to capture the tiny details of the face that are essential for the creation of the Face ID.

We recommend that you don’t stand beyond an arm’s distance from the camera to let it do the job.

Reset the Face ID of the iPhone

This is another way you can fix the issue if you are unable to activate Face ID on this iPhone. To reset the Face ID feature, you need first to open the phone settings.

Now tap over the option Face ID and passcode and then select the option Reset Face ID. There you are; set up the new details again, and your issue will be fixed.
