Apple today released iOS 15.4 and iPadOS 15.4, the fourth major updates to the iOS and iPadOS 15 operating systems that were released in September 2021. iOS and iPadOS 15.4 come a month after the launch of iOS 15.3.1 and iPadOS 15.3.1.
The iOS 15.4 and iPadOS 15.4 updates can be downloaded for free and the software is available on all eligible devices over-the-air in the Settings app. To access the new software, go to Settings > General > Software Update.
iOS 15.4 adds an option to use Face ID while wearing a mask, which works just like normal Face ID but scans the areas around your eyes for authentication. iPadOS 15.4 introduces Universal Control, allowing multiple Macs and iPads to be controlled with the same mouse/trackpad and keyboard.
