The Internet has previously exposed the various new features of Apple iOS 15.4, and everyone has waited for so long that the official version of iOS 15.4 has finally ushered in a push update. The iOS 15.4 not only optimizes the fluency of the mobile phone, but also adds a number of small details, the most important thing is to make up for the historical shortcomings of wearing a mask can not use the face ID, after updating iOS 15.4, the user experience has been improved again, and Xiao M is still very recommended for everyone to upgrade.
It is worth mentioning that the use of face unlocking by wearing a mask this time is not fully supported by the iPhone, but requires iPhone 12 or more models to be able to do it, that is to say, in the current Apple mobile phone, only the iPhone12 and 13 series are supported, and the iPhone X and iPhone 11 that also cancel the Touch ID with a full screen do not support this function. Of course, if you want the iPhone12 and 13 series to support wearing a mask to unlock face ID, the prerequisite is that you need to enter the system settings, re-enter the face ID according to the system prompts, and open the option of "wearing a mask to use face ID".
It is reported that the principle of wearing a mask to use face unlock is similar to ordinary Face ID, except that the area scanned by wearing a mask to use face unlock is smaller and more accurate, and the mobile phone is authenticated and screened by scanning the area around the eyes, and finally unlocked. As for why the iPhone X and iPhone 11 series do not support this feature, Apple did not explicitly indicate. In addition, there is also news that there is a certain difference in the speed between wearing a mask to unlock and not wearing a mask to unlock, and there will be a certain delay in the speed of wearing a mask to unlock, but there is no perception in use.
In addition to wearing a mask and using the face to unlock this larger functional upgrade, iOS 15.4 also added 37 new emojis. This includes emoticons such as home and gestures, and many emojis offer a variety of skin tones to choose from, which are basically full in detail. In addition, the most interesting thing is that there are many subtle facial expressions in this expression, such as biting the lips, peeking at the eyes, etc., and the subtle and diverse expressions provide users with more playability, and can also provide users with more accurate expressions.
In addition, wearing a mask to use face unlock and new expressions, iOS 15.4 also enriches the real-time text function of Notes and Remedys, when we open the above application, click the camera button in the APP will appear "Scan Text" function (Scan Text), we can copy ourselves in the scanned text, greatly increasing the efficiency of work. iCloud Keychain and Universal Control are also two features that increase the user experience, and I will not elaborate too much here.
Apple also fixed many of the bugs left over from the previous version. For example, when we type, the keyboard may insert a period headlessly and brainlessly on the number key we type, the photos in the album cannot be automatically synchronized to the iCloud photo library, the auxiliary function of the reading screen is not compatible with the "Book" App, it will be accidentally flashed back when using, and the "real-time listening" cannot be turned off in the "Control Center".
Xiao M feels that this iOS 15.4 is still very worth upgrading, because wearing a mask to use face unlock is a very important and practical function today, and iOS 15.4 also improves the fluency of the system and fixes many bugs in the previous version. Of course, if you think that the system may be unstable after the upgrade, we can also upgrade later to let the bullet fly a little longer, but this version is definitely a version that has to be upgraded, especially for users above the iPhone 12.
