All The New Features You Will Witness In One UI 9 Beta 4
First things first, we have brought you the list of all the new features, or the major changes that your Samsung phone will witness after you install the One UI 9 Beta 4 update. So, have a look.
Redesigned Quick Panel
Samsung has thoroughly cleaned up the Quick Settings grid. The sliders for brightness, volume, and the media player are now completely independent and highly resizable to fit individual layout preferences. The visual clutter is reduced by trading blocky borders for cleaner, borderless circular tiles.
In-Browser AI Hub
The Samsung Internet browser introduces an integrated “Ask AI” side panel powered by Perplexity AI. This tool provides real-time, contextual web page summaries and answers direct queries on the fly without forcing you to open a new browser tab or leave your active split-screen workspace.
Overlay Game Booster
One UI 9 Beta 4 brings a great upgrade with which gamers can now tweak crucial hardware settings without minimising their session. The revamped Game Booster panel functions as an immediate overlay, letting you adjust screen resolution, change the screenshot format, toggle performance profiles, and view real-time CPU metrics.
Glassy UI Aesthetics & Dynamic Media
The update pushes a smoother, translucent “glass morphic” design across the notification shade and system panels. The lock screen media player is a crowd favourite on Reddit, now ditching static cards for an active, colourful waveform animation that shifts dynamically to match the current track’s album art.
Android 17 Scoped Privacy
Leveraging the core upgrades of Android 17, One UI 9 strips away the “all-or-nothing” approach to app permissions. A new native contacts picker allows you to grant apps access to specific individual contacts rather than your entire address book. Advanced Protection Mode also locks down memory-level exploits.
