The new version also includes 37 new emoji.
As the name iOS 15.4 indicates, the new version represents the fourth new update to the basic version of iOS 15 and was launched with the iPhone 13 smartphone last September.
These updates, which started with 15.1 last December, added more features and functionality to Apple’s smartphone operating system and improved existing versions.
The new “Universal Control” feature also allows the use of other Apple devices as a second screen for the smartphone, while moving the contents of the phone between the two devices in an easy way as if they were one device.
This feature was first revealed as part of the Mac OS X Monterey operating system, but its release was delayed during the fall, and then talk about its rollout began this spring. This feature was part of the beta version of iOS 15.4 and was released as a beta feature in Monterey OS 12.3 and iPad OS 15.4.
Since the Universal Control feature is still in the beta phase, some problems may appear during its use and it may not work with all iPhone devices currently.
And Apple updated the “Face ID” feature so that it can be used with iPhone 12 and later generations, while wearing a muzzle.
And because this feature depends on a small part of the user’s face to identify his identity, the user needs to be more accurate in relation to the angle of the phone while photographing the face when using the “FaceID” feature.
