At the Apple conference and during the review of the feature of opening the phone by face recognition, Craig Federighi tried using it but the iPhone refused to open and asked him to enter the passcode and made Apple ridiculous. But Apple has explained what happened and that there is no defect but the secret is that before the conference, Apple’s team was preparing the devices so more people used the iPhone X, specialized for the show, and because they are not Craig, they did not notice that the phone was trying to monitor their faces and when found more than Someone, it has turned off the feature for security and asked a passcode for confirmation, and then restored the possibility of opening the phone with a Face ID.
