The OS shipped for Pixel phones slightly less than a month ago, and today already, Samsung is pushing out Android 12 updates for the flagship Galaxy S21 series. > Samsung's version of Android 12 is called "One UI 4" and is heavily skinned. It paves over all of Google's Material You design in the new OS, replacing it with Samsung's own version. Material You's most striking feature is the ability to color-match your UI with your wallpaper, which hasn't survived in Samsung's skin. You can manually pick a "color palette" through a UI that looks a lot like Material You, but the color isn't applied in as many places as Google's UI. Mostly it seems to color buttons and switches.
