The American electronics company “Apple” has introduced a new version of the operating system for smart devices, which is iOS 15.4, and it has new features that make it easier to access the iPhone smartphones and enhance its functionality.

The new version of the operating system has a long-awaited feature called “Universal Control” to enable the “Face ID” function, which means “using facial features as a password to unlock the iPhone.” There are also 37 new emojis in the version.

As the name implies iOS 15.4, the new version marks the fourth new update to the basic version iOS 15, and it was introduced with the iPhone 13 smartphone last September.

Launched with 15.1 last December, these updates add additional features and functionality to the Apple smartphone operating system and upgrade existing versions.

The new “Universal Control” feature allows other Apple devices to use the screen as a second screen for the smartphone, while moving the contents of the phone as easily as a device between two devices.

This feature was first revealed as part of the Mac OS X Monterey operating system, but its release was delayed in the fall, and then there was talk of its release later this spring. This feature was part of the iOS 15.4 beta, and was released as a beta feature in Monterey OS 12.3 and iPad OS 15.4.

The “Universal Control” feature is still being tested, so some issues may arise when using it, and it may not work on all current iPhone devices.

Apple has also updated the “Face ID” feature so that it can be used as a face mask for the iPhone 12 and later generations.

Also, this feature identifies the user based on a small area of ​​his face, so when using the “FaceID” feature, the user must be very precise about the angle of the phone when photographing the face.
