The beauty of the | is infinite
In the first week of the resumption of work in the 2022 Chinese New Year, the smartphone market is not busy. Redmi K50 official announcement, Samsung Galaxy S22 Ultra listing, Tianji 9000 new machine good things are nearing, the manufacturers of a new round of arms race has begun, the end of 2021 the big shine Apple is no exception.
This is not recent, Apple officially pushed iOS / iPadOS 15.4 developer preview to iPhone and iPad users, that is, iOS 15.4 beta 2, of which netizens have taken the lead in tasting, Face ID technology, Tap to Pay, wallet and other functional adjustments caused many users to cheer, and even "iPhone launched click payment function" entry directly on Weibo hot search, reading easily over 100 million. Although there are already many channels that have released the installation package of iOS 15.4 beta 2, Mingmei Unlimited does not recommend that you try it with your own main machine.
First of all, as the list of iOS 15.4 updates, may be the most concerned function, "wear a mask to use face ID" has actually appeared in the previous iOS 15.4 beta1.
To use this feature, simply check "Face ID and Password" in the "Face ID and Password" option set by the system. In order to enhance the accuracy of unlocking after wearing the mask, you can also re-enter the Face ID once or twice after this.
It is worth mentioning that in the description information of the system, it is not difficult to find that after opening the function, the iPhone is actually based on the contour information around the user's eyes to carry out facial recognition. This explains why in iOS 15.4 beta2, when the iPhone detects that the user's eyes are not on the screen, it will pop up the prompt of "look down to unlock".
Judging from mingmei's unlimited testing experience, in iOS 15.4 beta2, "wearing a mask and using face ID" has been very mature. Basically, even if the fuselage is deliberately at a very large offset angle from the face, the iPhone can complete the recognition and unlocking of the face ID in 1 second. It has to be said that this fully demonstrates the precision advantage of 3D structured light compared to ordinary 2D facial recognition.
And it is worth mentioning that after turning on the "Wear a mask and use face ID" function, you do not have to wear a mask when re-entering facial information. At the same time, this function can also be used in conjunction with the unlock function of wearing glasses. Of course, completely opaque sunglasses obviously don't work.
In addition, look at the iOS 15.4 development version of the most popular feature Tap to Pay (click on the payment function), merchants only need to tap the iPhone to use the iPhone to accept Apple Pay, contactless credit/debit cards and other digital wallet payments, but it should be noted that this function is currently only used in the United States, and it also requires third-party vendors to add support. The author believes that the operation principle of this function is somewhat similar to that of domestic subway and bus security inspection equipment, and the iPhone in the hands of NFC merchants can be transformed into a collection tool, and payment can be completed with a touch - collection operation.
In addition, of course, it has to be mentioned that in the iOS 15.4 beta version, the ProMotion variable refresh rate technology of the iPhone 13 Pro and iPhone 13 Pro Max is opened to all third-party apps at the bottom. In theory, this will significantly improve the smoothness of these two flagship models in daily use, but also means that for third-party developers, macOS, iPadOS and iOS are fully prepared for "high brushing".
In addition, according to the convention, it is expected that the official version of iOS 15.4 will be pushed to users before and after Apple's spring conference, and practical functions such as mask unlocking will be officially launched.
According to the current rumors from the outside world, Apple's spring conference will most likely be held on March 8.
At that time, the official version of iOS 15.4 may be pushed after the conference, and the time interval is about March 14 ~ 16. We'll see.
Finally, Mingmei Infinity will summarize the situation of whether the official version of iOS 15.4 is upgraded or not today:
1, iPhone 13 series users if still stay in the iOS 15.1.1 system, there is no need to upgrade, of course, if you have been waiting for the mask unlock function online group, you can rest assured to upgrade.
2, if you have upgraded the new system of iPhone 12 and iPhone 13 series users, you can close your eyes to update the new system, after all, wearing a mask to unlock the new feature has a high practicality, wearing a mask may become the norm of later life.
3, iPhone 11 series and below models of Apple mobile phone users, can consider continuing to wait and see, do not have to rush to upgrade.
In summary, what other suggestions and ideas do you have, welcome to discuss together.
