On March 15, Apple released the official version of iOS/iPadOS 15.4 (build number: 19E241), which is the fourth major update for iOS/iPadOS 15, a month after the last update. The small partner who updated the iOS/iPadOS 15.4 RC version should not receive this official version update, because the RC version number is the same as the official version number.
To say that the most important feature of the official version of iOS/iPadOS 15.4, presumably is to wear a mask to unlock, users who have been updated can unlock the iPhone through Face ID while wearing a mask, and no longer need to use the digital password to unlock frequently. The new feature requires the user to enter an additional face data wearing a mask and glasses, and the face after the entry can even be used to pay, but the security will be reduced.
The Android camp also has some phones with 3D face unlock, but they don't have fingerprint unlock like the iPhone, so the mask unlock feature is relatively less important for Android users.
It is worth mentioning that the mask unlocking is only supported by the iPhone 12 series and subsequent models, as for the iPhone 11 series and previous mobile phones, Xiao Lei expects that Apple will not push in the follow-up, want to experience this convenient and fast function, there is no other way except to buy a new iPhone. In addition, the iPad Pro with Face ID function still does not support the mask unlock function, which is a pity.
The new version of the iOS system also introduced 120Hz Promotion support for third-party Apps, but the need for App developers to adapt, as for whether Apple official will force software vendors to promote adaptation work, it is still unknown, but Xiao Lei believes that there is a high brush screen in the air, but can not have a comprehensive high brush adaptation, the use experience will inevitably be greatly reduced, promote the global high brush, but also the joint efforts of software developers and mobile phone manufacturers.
In terms of iPad, the universal control of skipping tickets for several months is finally online, and several Apple devices that are connected to each other only need a set of keys and mice to carry out cross-screen circulation operations. It is reported that universal control only supports up to 3 devices connected at the same time, and must have a Mac. Compared with the accompanying function, universal control can better play the convenience of multi-device linkage, rather than just treating other Apple devices as the expansion display of the Mac.
It has been more than two years since the outbreak of the epidemic, and the official update of iOS can be said to be late to meet and hate, solving the biggest pain point for users to use iPhone outdoors. The launch of the universal function of iPadOS has also better improved the efficiency of interconnection between devices, and it is more convenient to experience.
