iOS 15.4 on an iPhone

Apple has stopped signing iOS 15.4.1, which launched in March this year. The Cupertino-based company does this regularly to get users to update their devices to the latest version.

iOS 15.4 introduced some notable features, such as iPad Universal Control, new emojis, and the ability to unlock iPhones without removing face masks.

In the meantime, iOS 15.4.1 released a fix for the battery drain issue for affected iPhones, as well as a bug in AppleAVD to prevent it from being exploited. Apple says there may be individuals trying to exploit this bug and recommends updating to iOS 15.4.1 as soon as possible.

In similar news, Apple has also stopped signing HomePod 15.4 and tvOS 15.4.
