On January 28, Apple pushed the first beta version of iOS15.4, many small partners are afraid of bugs and dare not upgrade, january 29 pushed a relatively stable iOS 15.4 beta version.
This public beta version is not the same as before, it does not castrate all the functions of the internal beta version, basically all of them, including universal control, Face ID recognition of faces wearing masks, new Emoji emojis, etc.
In addition, after the iOS update, Apple has also added a third-party application 120Hz display function for the iPhone 13 Pr series to make full use of the screen refresh rate.
This pile of text is not important, the most eye-catching is the "Face ID recognition of the face of the person wearing a mask", after all, the mask is foreseeable to become a necessity of life for a long time in the future, every time you unlock / pay the password feel that the technology has gone backwards for ten years, if face ID recognition mask face is good enough, the iPhone party will not have to saliva with envy on the Android screen fingerprints ~
