There are some exciting features included, such as the ability to use Face ID with a mask (only for iPhone 12 or newer), access to 37 new emoji (like bubbles, biting lip, crutch, etc), and Universal Control, which lets you work with a single mouse and keyboard and move between Mac and iPad for a seamless experience - no setup required.
