Samsung has kicked off its One UI 8 beta program—based on Android 16—for the Galaxy S25 series, giving eager users an early taste of what’s next in the brand’s software evolution. The beta is live now on the Galaxy S25, S25 Plus, and S25 Ultra in the US, UK, Germany, and South Korea, though notably the new S25 Edge is absent from the first wave. Enthusiasts can enroll via the Samsung Members app to download the roughly 3.38 GB update, which carries the May 1, 2025 security patch.

As expected, Samsung is spotlighting AI enhancements in One UI 8. The company teases “improved multimodal capabilities” and deeper personalization, claiming AI Select now fires up instantly with no lag—eliminating the brief startup delay that dogged the previous release. Beyond speed, leaks and hands-on previews hint at expanded functionality for the “Now Bar,” which now surfaces incoming calls and Do Not Disturb status right in your stream of updates.

Rumor has it Android Central spotted references to “Audio Brief,” an evolution of One UI 7’s Now Brief, offering personalized audio summaries of your day based on calendar events, messages, and app activity. And while Samsung’s changelog remains frustratingly light on specifics, the company’s official blog promises “intelligent multimodality” that lets the system understand what you’re looking at—be it a photo, video, or live scene—for smarter contextual assistance.

Samsung is quick to point out that One UI 8 is “optimized for the unique form factors across the Galaxy product portfolio,” echoing Google’s push for Android 16 to better serve tablets and foldables. On the S25 series, that means a fresh split-screen trick: you can now slide one app partially offscreen to the edge, shrinking it into a floating pane while you focus on your main task—a move reminiscent of OnePlus’s multitasking tools on the Open.

One UI 8 also brings polish to Samsung’s core apps and services. The Reminder app gets a cleaner layout for easier to-do management and sharing with friends or colleagues. Quick Share, Samsung’s AirDrop-style file service, now boasts a simplified interface: files transfer faster, and you can initiate a share directly from the quick settings toggles without digging into menus.

Accessibility buffs will appreciate Android 16’s support for Auracast, which lets hearing aids or compatible earbuds (like the Galaxy Buds3) hop onto shared audio streams—from airport announcements to concert feeds—via Bluetooth broadcast. This ties into Google’s broader push for Auracast across the ecosystem, and Samsung’s implementation via quick-tap QR codes in the Control Center feels smooth in our testing.

The One UI 8 beta is rolling out now in the initial regions (US, UK, Germany, South Korea) for unlocked and carrier-locked S25, S25 Plus, and S25 Ultra units. To join, open the Samsung Members app, tap “One UI 8 Beta Program,” register, and download over Wi-Fi only. India, Poland, and additional markets may get access in a second wave, but Samsung hasn’t confirmed precise dates yet.

Build numbers for the first beta include S938NKSU3ZYER (South Korea), S938NOKR3ZYER (US), and region variants; later updates should polish bugs and add features ahead of the stable launch.

Samsung confirms that One UI 8’s stable rollout will kick off this summer on its next-generation foldables—the Galaxy Z Fold7 and Flip7—before cascading to older flagships. The company calls this “a new era of software intelligence,” promising faster AI Select, proactive Now Bar insights, and UX tuned to each device’s shape and size.

It’s also an opportunity for Samsung to redeem itself after the slow trickle of One UI 7 updates, which left many users waiting months for Android features. With a more streamlined beta program and clear roadmap, One UI 8 promises a more predictable cadence and quicker fixes—good news for anyone tired of lagging behind the Android curve.

If you’ve got a Galaxy S25 series handset and crave the latest Android 16 + AI goodies, now’s the time to jump into the One UI 8 beta. Just remember: betas can be bumpy, so back up your data, join the Samsung Members feedback channels, and get ready to explore Samsung’s freshest software innovations ahead of the pack.
