What is the update content of the official version of iOS/iPadOS 15.4 and what is the value of the update?

Apple released the official version update of iOS/iPadOS 15.4 this week, which is the fourth major update of iOS15 and iPadOS15. Update build number is 19E241.

The main update content is as follows:

1: Strengthen 5G signal

In this update, 5G iPhone has achieved Full support for mobile N28 700Mhz band. This band is characterized by lower frequencies and therefore wider signal coverage. No matter where you are, you can enjoy a more stable and faster 5G network. This update brings a better network experience to users, making mobile phone use more convenient and efficient.

2: Added unlocking iPhone with a mask

When you turn on the phone, the system will prompt you to enter the facial features when wearing a mask. However, you don't need to wear a mask when registering new facial features, because unlocking is authenticated based on unique features around the eyes. Therefore, even if you change the mask, it will not affect the unlocking. If you wear glasses, the system also supports adding up to 4 facial features when wearing glasses. This upgraded facial recognition function also supports facial payment. It should be noted that this feature is only available for iPhone 12 and above models.

3: Add scanned text

When using the memo or reminder function, you can easily convert pictures into text. Just click on the camera icon and the system will automatically recognize the text content in the picture and convert it into editable text. This function is very practical and can help you quickly record and organize information, eliminating the trouble of manual input. Whether it's shooting notes, business cards, recipes or other text materials, you can quickly convert them into text through this function, making it easy for you to check and edit at any time. Let’s try this convenient and practical function together!

4: Intelligent Shortcut Commands

In the past system, a notification would pop up every time a shortcut command was automated. However, after upgrading to iOS 15.4, we can set up automation rules individually to turn off notifications during runtime. This means that we will no longer receive notification alerts when our automation rules fire. This update gives us a more flexible and personalized automation experience.

5: 37 new emoji expressions

Men are pregnant, men are full.

Is the official version of ios15.4 worth updating?

"Word Play Flower" is a popular text puzzle game, and the nostalgic cleaning level in it has attracted much attention. In this level, players need to find 12 items in the picture that do not match the era. The battery life of the game is average and has not been significantly improved, but overall it is smoother than the beta version. If your game version is 12 and above, I strongly recommend you to update for a better gaming experience.

It is recommended to use Apple's data management tool to back up iPhone data before upgrading to prevent data loss during the upgrade process. Apple Data Management Tool is a professional backup software that can back up photos, contacts, text messages and other data in iPhone with one click for free. In addition, it also supports selective backup. After the backup is completed, you can preview and export the data online, which is very simple and convenient.
