Samsung has rolled out the third One UI 8 beta update for the Galaxy S25, S25 Plus, and S25 Ultra, bringing users in select regions closer to the final Android 16 experience. This update, weighing around 800MB, focuses on fixing bugs and boosting performance for a smoother user experience.

The new beta, with firmware ending in ZYFB, is available in countries like the US, UK, Germany, India, South Korea, and Poland. It tackles issues from earlier betas, improving app stability, especially for the camera, and enhancing overall system reliability. Users can expect fewer glitches and better performance in daily tasks.

Samsung also added minor tweaks, like improved animations and refined Galaxy AI features, to make the interface feel more polished. To join the beta, Galaxy S25 owners in supported regions can sign up through the Samsung Members app.

However, the update is exclusive to the S25 series for now, with no word on when older devices like the Galaxy S24 or S23 will get it. Samsung seems to be fast-tracking One UI 8, as a stable version with firmware BYFB was recently spotted, hinting at a possible release soon after the Galaxy Unpacked event on July 9, 2025.

This beta program lets users test new features early, but it’s not perfect yet. Samsung is working hard to iron out remaining issues before the official launch, ensuring a solid experience for all Galaxy users.

Samsung has started rolling out the One UI 8 Watch beta update for the Galaxy Watch 7 and Galaxy Watch Ultra in the United States and South Korea. This update, based on Wear OS 6, brings exciting new health-focused features to help users stay fit and healthy.

The update includes tools like Bedtime Guidance, which suggests the best time to sleep based on your daily routine, and Vascular Load, which tracks stress on your heart during sleep. There’s also a Running Coach that offers personalized tips and real-time advice to improve your runs, but it’s only available on the Galaxy Watch 7 and newer models.

Another feature, the Antioxidant Index, measures healthy aging markers using the watch’s sensors, though it’s exclusive to the Galaxy Watch Ultra. Only select Galaxy Watch models, starting from the Galaxy Watch 5 series, can join the beta program.

Sadly, the Galaxy Watch 4 series won’t get this update. If you’re in the U.S. or South Korea and own a compatible watch, you can sign up through the Samsung Members app, but spots are limited.

The beta program lets users try these features early, with a stable version expected to launch with the Galaxy Watch 8 series in July 2025. Older compatible watches will get the stable update later, likely in late July or August. This update shows Samsung’s focus on improving health tracking for its smartwatch users.

Samsung is rolling out the One UI 8 Watch Beta Program, giving users a sneak peek at new features for Galaxy Watches. Based on Wear OS 6.0, this update will first appear on the Galaxy Watch 8 series next month. Before the official release, Samsung is opening the beta to select users with Galaxy Watch 5 or newer models in the US and South Korea.

The beta introduces four health-focused features: Antioxidant Levels, Bedtime Guidance, Running Coach, and Vascular Load. These are already showing up in the latest Samsung Health app (version 6.30.2.027) on devices like the Galaxy S23 Ultra running One UI 7.0.

However, not all features work on every watch. For example, Vascular Load is exclusive to the upcoming Galaxy Watch 8 or higher, while Running Coach requires a Galaxy Watch 7 or Ultra for its running test.

To join the beta, users in the US or South Korea can use the Samsung Members app on their paired Galaxy phone. Log in with the same Samsung account as your watch, find the One UI 8 Watch Beta banner, and sign up.

The program starts in June 2025, but spots are limited. Samsung plans to launch the stable version alongside the Galaxy Watch 8 series at next month’s Unpacked event. Stay tuned for more updates.
