Face ID has always been a proud feature of the Apple app on the iPhone X, unlike traditional 2D face recognition. Apple combines hardware and software to achieve a secure and convenient unlocking and payment experience. Its principle is to capture and analyze more than 30,000 invisible points through the front original camera to capture accurate facial data to create a depth map of the user's face; it also captures the infrared image of the user's face. The neural network engine of the A11 biomimetic chip is partially stored securely in the security compartment. It converts the depth map and infrared image into a mathematical representation and then compares this representation to the registered facial data.
And the most amazing thing is that the face ID will automatically adapt to the user's appearance changes, such as makeup or facial hair. When wearing hats, scarves, glasses, contact lenses and all kinds of sunglasses, the face ID can still work normally. In addition, it works well indoors, outdoors, and even in a black environment. However, since the release of the iPhone X, many users have encountered problems with the face ID not available.
In a recent document to Apple Store and an authorized service provider, Apple pointed out that if the user's iPhone X has a problem that the face ID is not available, the rear camera needs to be replaced first. If it is invalid after replacement, the whole machine is replaced. It is speculated that the reason why the facial ID is not available should be that the iPhone X front-end original camera has a problem. At present, we still do not know the relationship between the original deep-sensing camera and the rear camera. Apple's explanation is that the original deep-sensing camera is associated with the rear telephoto camera, so it will cause similar problems.
Since the iPhone X has only been on the market for only half a year, if the user has a problem that the face ID is not available, please go to the Apple Store or Apple Authorized Service Provider for repair or change. We will also continue to pay attention to the latest developments in this issue.
