At one o'clock in the morning on 3.15, Apple officially launched the official version of iOS 15.4, and the current 15.4 system is the largest update of iOS 15, and the main function it brings is to support mask unlocking.
The epidemic is now breaking out everywhere, every day is to wear a mask to go to work, wearing a mask on the Apple machine to unlock and pay is very troublesome, many people have turned off the face function, but this face function is chicken ribs.
Although Apple started with the iPhone X with face recognition, only the 12 and 13 series models support mask unlocking. "Deep Integration" technology has been added to the 12 and 13 Series Face components, while the iPhone X/XS/11 Series does not have this technology, so it does not support wearing a mask to unlock.
Everyone looks different, and face recognition is recognized by recognizing unique features around the human eye, and then fusing the entire face to achieve an unlocking effect. Wearing a mask to support unlocking also supports the payment function, and wearing glasses does not affect the use, and the unlocking speed is not much different from before.
Click to wear a mask to use a Face ID, you don't need to bring a mask during the recording process, and you can also choose to wear glasses. That is to say, even if you wear a mask and wear glasses, it will not affect the use of facial function, and it can only be said that the facial fusion technology is still very powerful.
The epidemic is repeated and intermittent, wearing a mask in the next few years is still a daily necessity, the epidemic has existed around us for several years, Apple is now launching a mask to unlock the use is still very large, convenient and safe.
The new version of iOS 15.4 adds 37 emoticons, 75 skin tones, and emoji packs are more abundant. The most controversial is the increase in the expression of male pregnancy.
Previously, there were many criminals who used AirTag to track people, causing heated discussion on the Internet, after all, Apple brand trackers are still very popular. Added an anti-tracking warning in 15.4, prompting when setting up AirTag: Criminal behavior when using AirTag to track others without consent. Added "Custom Tracking Notification" If someone else is using AirTag to track you, the phone will send you a relevant alarm reminder, which is the anti-tracking function.
There is also a theoretical signal enhancement update, the baseband version of 15.4 and the carrier version have been upgraded, adding a signal band, adding China Mobile N58 5G 700MHz band support. The coverage rate of this band is wider than that of other China Mobile bands, so in theory, the signal of mobile 5G users will be improved in the new version.
