One UI
One UI is Samsung's user interface. It sits on top of Android on Galaxy smartphones and tablets and determines the look, menus, and many extra features.
What does One UI mean?
Android provides the base system, and One UI turns it into what you see on a Galaxy device: home screen, settings, quick menu, and Samsung's own apps. Features such as DeX or support for the S Pen are part of it too.
New versions usually arrive together with a new Android version and gradually reach older devices through updates. The Galaxy Watch runs its own version, which is built on Wear OS.
A general explanation of the term, not from a video. How it plays out on a specific device in everyday use is covered in the reviews below.
