An early One UI 8.5 build, spotted on Samsung’s servers for the Galaxy S25 Ultra, has been modified to run on a Galaxy S21+, giving us a first look. The update brings a refreshed Settings UI with more compact items, a bottom search bar, drop shadows, gradient effects and an iOS-like floating back button. One UI 8.5 is expected to debut with the Galaxy S26 series early next year.
