• One UI 8 brings a cleaner UI, redesigned stock apps such as Gallery, Samsung Internet, and Weather, and updates to existing Galaxy AI features including Now Brief and Audio Eraser.
• Early One UI 8.5 test builds seen on the Galaxy S25 Ultra show a deeply customizable Quick Panel with resizable tiles and sliders, optional horizontal or vertical controls, free placement of items, and visual tweaks like removing text labels in some app bottom bars.
• Additional 8.5 leaks point to blurred unread notifications and new clock styles on the lock screen, a revamped Software update screen that prominently displays the One UI version, and an internal S24+ firmware sighting that indicates active testing ahead of an expected launch with the Galaxy S26.
