The stable One UI 8 rollout has just begun, but leaks have already started revealing important details about its next iteration, One UI 8.5. We already know that Samsung has been working on it for months, and recently, the Galaxy S25 Ultra was spotted on the test server with One UI 8.5 build. Now, a leaked video has surfaced on the internet, giving us our first look at the software well ahead of its official release.
A developer, @Feruzbek_101, was able to somehow modify the One UI 8.5 internal beta build and run it on a Galaxy S21+. The video shared by him reveals Samsung is making UI changes across various apps and functions, including the Settings app, Galaxy Themes, and Studio Editor.
The changes become visible right from the boot screen. There’s a new One UI 8.5 logo on the boot screen with gradients around it, giving it a colorful experience. Samsung has been showing a minimalist “Samsung Galaxy” text on the boot screen for years. It’s good that Samsung’s making some changes there.
The Setting app is also getting some notable UI tweaks. The menu options are now compact, and there are no subtitle texts as well. The search bar is now located at the bottom, which is easier to reach, and there’s an overflow gradient on both top and bottom edges. There are also drop shadows on all containers and the search bar. The expanded search page now shows different categories in a three-column grid.
More changes are visible inside the Settings app when you tap on a specific item. The back button floats above the content and gets a drop shadow of its own, which looks similar to iOS 26. Furthermore, the One UI Home Screen page within the Settings page replaces the dummy icons with real ones.
The Phone app may be getting a big UI overhaul in One UI 8.5. As the video shows, the traditional three-tab structure is replaced with a pill-shaped design, making it easier to access options while also extending the screen’s usability. The Galaxy Studio is also getting a pill-shaped UI element. This could be implemented in more stock apps to offer users a streamlined user experience.
One UI 8.5 also brings design changes to the Galaxy Themes app. The app launch page features a giant brush icon, perhaps aiming to convey a colorful and tweaking vibe. Inside, the app shows pill-shaped buttons. The Device Care section gets a revamped UI, featuring a card design for the device health status. The individual options below show long progress bars.
