Focus is an very useful new feature coming to iOS 15
SharePlay is a new feature for FaceTime that allows users to share streaming video with others over the app, or even share tunes streaming over Apple Music with others. Live Text turns text found in photos snapped by the user, including handwritten notes, into emails and messages.
While you can taste iOS 15, the fact is that the beta version is not stable which means that certain features that you might rely on everyday might not work correctly. And that goes for battery life which takes it on the chin in beta variants. So even if your taste buds have you drooling, it is still best if you wait for the final version of iOS 15 to be made available before you chow down.
In iOS 15 beta 3, other changes include a new splash screen for the App Store, new options for spoken directions in Maps, and the music widget has been redesigned to become the color of the currently playing album. In the beta, Apple returned the physical reload button to Safari and also made a change to the universal search bar. In the first two betas, this bar started on the bottom of the page but moved to the top when text was being entered. Now, in the third beta, it sits above the QWERTY keyboard.
