January 28 news, Apple only released the official version of iOS 15.3 yesterday, and today added a blockbuster new feature to the iOS 15.4 beta version that aims to make Face ID can be used while wearing a mask, and without the help of Apple Watch certification. Apple said the feature can "recognize unique features around the eye" for certification purposes.
If the user chooses to use this feature during setup, they will need to rescan your face to get Face ID. Since then, Face ID has unlocked the owner's iPhone, even if you're wearing a mask.
In the Settings app, there's a new "Use Face ID when wearing a mask" toggle key that you can choose to turn on or off at any time if you change the way you wear your mask, and a new feature of "Add Glasses" that makes Face ID more accurate when you're wearing glasses and masks at the same time.
Apple warned in its settings app that face ID is "most accurate" when it is only set to full face recognition. For Face ID with a mask to work, you have to look at the device to get it unlocked, and it doesn't work when you wear sunglasses.
The good news is that for the current epidemic environment, whether it is now or in the future, masks will be the indispensable standard for our travel, and before we could only unlock with the help of Apple Watch, iOS 15.4 joined the mask unlock is more of a means for Apple to solve the problem, unlike before, only taking into account users with Apple Watch.
Of course, perhaps as soon as this year or even next year, the iPhone will join the screen recognition unlock, but for now, the majority of users may be more looking forward to the official version of iOS 15.4 to push as soon as possible.
