“I recently updated to iOS 16 and my iPhone 13 has stopped accepting Face ID. I have repeatedly restarted the phone; each time it tells me 'Unable to activate Face ID on this iPhone'. How do I restore Face ID?”
A lot of people have experienced Face ID activation issues especially after an iOS 16 update and perhaps one of the most common problems is the error message of "Unable to Activate Face ID on this iPhone".
This error prevents users from setting up Face ID or using it correctly. In this article, we will explain some possible reasons for unable to activate Face ID on this iPhone and what you can do to fix this error.
Below are some possible reasons for the error "Unable to activate Face ID on this iPhone":
Before we get into more in-depth solutions, it is likely that the problem is caused by the improper use of Face ID and therefore you should consider the following:
To set up Face ID, the TrueDepth Camera on you iPhone should be able to recognize your face properly. Make sure that your entire face including your eyes, nose and mouth are fully visible to the camera. Do not wear a face mask or sunglasses when attempting to set up Face ID and make sure you are in a well-lit room.
At the same time, you need to make sure that nothing is covering the TrueDepth camera. If the iPhone has a screen protector or phone case, remove it before attempting to set up Face ID. You should also clean the camera to remove any dust or dirt that could be obscuring the camera.
On iPad, you can use Face ID when your device is in any orientation. However, on iPhone, you need to put the device in portrait orientation to allow the camera properly "seeing" your face.
In addition, your iPhone or iPad has to be closed enough to your face to adequately capture your face's details for Face ID working correctly. The device shouldn't be further than arm's length and also make sure that there is adequate light on your face.
