Here it comes, this time it really comes!
The developer preview version of Apple iOS 15.4 has been pushed many times before, bringing many heavy and practical features, and many small partners have not waited to try it. The good news is that just this morning, Apple pushed the official update of iOS / iPadOS 15.4, the update package capacity is 1.32GB, which is also the fourth major update of iOS 15 and iPadOS 15, iPhone finally supports wearing a mask Face ID unlocked!
Recently, the epidemic has been repeated, Apple's epic update is simply a timely rain, wearing a mask to unlock the iPhone is really convenient. Let's explore the latest iOS 15.4.
How can iOS 15.4 be updated?
iOS 15.4 and iPadOS 15.4 updates are available as free downloads, and all eligible devices can be updated wirelessly in the Settings app at The Settings > Universal > Software Update.
What are the key features of iOS 15.4?
Supports wearing a mask to unlock with Face ID
iOS 15.4 added an option to use Face ID when wearing a mask, which works like a normal Face ID but scans the area around the eyes for authentication. Users can also use Face ID wearing a mask to make Apple Pay payments and autofill passwords in apps and Safari.
When the user is specifically operating, he needs to wear a mask to enter a lower recognition, and add a face ID that supports wearing a mask in the setting. It should be noted that at present, this function only supports iPhone 12 and iPhone 13 series models, although iPhone X, iPhone XR, iPhone 11 and other models also use face recognition technology, but temporarily do not support the "mask unlock" function.
After the iOS 15.4 upgrade is complete, the individual's face will be required to be entered again. Note that the face data entered is the same as before, and there is no need to wear a mask for scanning.
After entering the system, you can wear a mask to unlock, test it, block the eyes or half of the face can be unlocked, but the unlocking speed will be a little slower than not wearing a mask. It is estimated that the face ID needs to recognize the mask first, and then identify the features around the eyes, if the user blocks the eye part, it cannot be unlocked, which shows that this function has higher requirements for eye features.
In addition, this time also increased the entry of wearing glasses, when set to identify each pair of glasses you often wear, the recognition effect is more accurate, currently do not support sunglasses.
During the epidemic period, iPhone users who want to unlock their phones must take off their masks, which is inconvenient and increases the risk of infection, so wearing a mask to unlock this update is really useful.
Universal control
This new feature is available in the iPad OS 15.4 Beta release, we can control multiple computers and iPad tablets at the same time through a set of mice (touchpads) and keyboards on Mac computers, provided that your device is logged in to the same Apple account.
In this way, our efficiency will be greatly improved when we use multiple devices to work together, and the desktop will not appear messy because of too many keys and mice, and it will not be because of frequent switching of devices and walking around, so that a set of keyboards and mice are all done, which is quite practical function.
Added 123 new emojis
iOS 15.4 official version in the emoji keyboard also added 123 new expressions, including "melted face, pregnant father, tears held back" and other expressions, apple now does not study mobile phones, instead of research how to make men pregnant? In addition, the handshake emoji can also select the skin color of each hand individually, which is very detailed.
The new emoticons include all 112 of the 112 that the Unicode Alliance approved for inclusion in Emoji 14.0 last September, and the updated emoticons are also the largest number of emojis introduced in a single apple update since iOS 11.1.
Siri Assistant/Safari
With this update, Siri provides time and date information when offline on iPhone XS, iPhone XR, iPhone 11, and later models.
Safari Web Translation has added support for Italian and Chinese Traditional.

Health supports the EU Digital COVID-19 Certificate, which allows you to download and store verifiable COVID-19 vaccination records, test results and recovery records.
Meanwhile, the COVID-19 vaccination card in Apple Wallet now supports the EU Digital COVID-19 Certification Format.

After we update iOS 15.4, we can initiate a simultaneous sharing session directly from a supported app, which is faster and more convenient.
The simultaneous broadcast sharing function is a new interactive way for Apple, no matter how far away you are from your family and friends, you can watch dramas, listen to songs, and share screens together. At the same time, Chinese users can now also use the co-broadcast sharing function on Youku.

And some bug fixes for iPhone:

Do iOS 15.4 need to be upgraded?
This time the iOS 15.4 update has a capacity of about 1.3GB, which is very practical and takes up a small space. In particular, the new system also supports wearing a mask to unlock the iPhone, and this epic update alone is worth upgrading to iOS 15.4.
However, considering that the mask unlock function is currently only open to iPhone 12 and 13 series mobile phones, if you are using an older iPhone, you don't have to rush to update.
