After a month and a half and a total of 5 betas, the official version of iOS 15.4 has finally arrived as scheduled.
In the early hours of this morning, Apple released a system update for the official version of iOS 15.4, one month after the last official version.
The system version number for the official version of iOS 15.4 is 19E241, which is the same as the system version number of the RC version updated last week.
Users who have already updated the RC version do not need to upgrade, which is equivalent to using the official version one week in advance.
If you want to upgrade the official version, you can delete the profile and wait for the next official version to be pushed.
The official version of iOS 15.4, as the fourth major version update of the iOS 15 system, brings us many useful features.
Includes mask unlocking, universal control, optimized SOS emergency call, and new AirTag tracking function reminders.
In addition, iOS 15.4 also unlocks the high brush limit of third-party apps, supports data download system updates, and brings 37 new Emoji emojis.
Next, Xiaoguo will take you to see what new changes are worth paying attention to in iOS 15.4.
Mask unlocked
In order to solve the problem of difficult to unlock in the epidemic environment, Apple has launched a mask unlock function in the official version of iOS 15.4.
This functionality needs to be achieved by capturing the user's surrounding eye features.
When the user follows the system prompts to enter the features around the eye, the function can be used normally.
In the second beta of iOS 15.4, Apple also optimized this feature, adding an unlock prompt function.
When the user's eyes are not within the detection range of Face ID, a prompt is issued and the user needs to adjust the angle of sight according to the prompt.
In short, although the mask unlock function can recognize the limited facial area and the angle requirements are more stringent, the unlocking process is also very silky, which perfectly solves the problem of unlocking efficiency of the iPhone under the epidemic.
Xiaoguo believes that with this feature alone, the official version of iOS 15.4 is worth a liter.
However, due to the limitations of related support components, this function is currently only available for iPhone 12 and newer models, and small partners using iPhone 11 and below cannot use this function for the time being.
Universal control
In the official version of iOS 15.4, Apple officially launched the universal control function.
As introduced at the previous launch, as long as the device is under the same iCloud account, you can control iPad and Mac computers with a keyboard and mouse.
At the same time, the MacBook's trackpad and keyboard can be used directly on the display of the iPad.
When you want to control both iPad and Mac computers, you need to upgrade your iPad and Mac to the latest iPadOS 15.3 and macOS 12.3 releases, respectively.
Third-party apps high brush restrictions are lifted
In the official version of iOS 15.4, Apple officially unlocked the high brush limit for third-party apps.
Animations in all third-party apps now support display at a refresh rate of 120Hz for a smoother experience.
Using the iPhone 13 Pro model, you can upgrade the new system to experience it.
Emoji emoticons
In addition, Apple has brought 37 new Emoji emojis to the iOS 15.4 official system.
According to MacRumors, the new skin includes a melted yellow face, a two-hand gesture, a peek expression, a lip bite, a salute, a low battery, bubbles, and more.
iOS updates support cellular downloads
In addition, iOS 15.4 release includes the ability to download software updates using cellular data.
Even without WiFi, you can update your system over a cellular network.
Restore your Apple Watch
In addition, iOS 15.4 added a new ability to restore Apple Watch from iPhone.
When a user updates their iPhone and Apple Watch to iOS 15.4 and watchOS 8.5, respectively, a red exclamation point appears on the screen when the Apple Watch needs to be updated or restored.
At this point, the user simply places the Apple Watch on the charger, double-clicks the apple Watch side button, and follows the steps displayed on the iPhone.
In addition, Apple's official technical support documentation shows that this official update also fixes the following bugs:
The keyboard may insert a period between the numbers you type.
Photos and videos might not sync to iCloud Photo Library.
Speak Screen accessibility may quit unexpectedly when used in the Books app.
Turning off Live Listening in Control Center may not turn it off.
If you find similar problems in use, we recommend that you upgrade the iOS 15.4 release system as soon as possible.
That's all for iOS 15.4.
According to Bloomberg reporter Mark Gurman, the official iOS 15.4 system is the last major version update before the arrival of the iOS 16 system.
Judging from the updated content, iOS 15.4 is indeed a very substantial system version, including many heavy features, which is well worth upgrading.
In addition, Apple will officially release the green iPhone 13 series and the new iPhone SE on Friday, which have their own iOS 15.4 official system.
Friends who have purchased a new color of the iPhone 13 series can directly experience the iOS 15.4 official version of the system.
