Samsung has officially begun seeding the One UI 9 Watch beta – built on Wear OS 7 – to the Galaxy Watch7 and Galaxy Watch Ultra. This rollout follows last week’s beta release for the Galaxy Watch8 and Galaxy Watch8 Classic, signaling a broader push to bring the next-generation wearable experience to more users.
The update is a substantial one, packing in a redesigned interface, fresh widgets, and a handful of new health-centric tools. Among the headline additions are Antioxidant Index and Vascular Load support, though in the US, these are being replaced by the Blood Pressure Trend feature – a region-specific tweak that aligns with local regulatory approvals.
What’s New in the One UI 9 Watch Beta?
The One UI 9 Watch beta is more than just a visual refresh. Samsung has focused on making the smartwatch experience more intuitive and health-focused, with several key changes that users will notice immediately after installing the update.
Refreshed User Interface
The most obvious change is the revamped UI. Samsung has streamlined menus, animations, and notification panels to feel more fluid and modern. The quick settings toggles have been redesigned for easier one-handed access, and the app drawer now features a cleaner grid layout that reduces visual clutter.
Widgets have also received a significant overhaul. They’re now more interactive and customizable, allowing users to place key health metrics, weather updates, and calendar events right on the watch face. The new widget engine also supports smarter stacking, so the watch can automatically surface the most relevant information based on time of day or user activity.
Advanced Health Metrics
Samsung continues to push the boundaries of wearable health tracking. The beta introduces two new metrics: Antioxidant Index and Vascular Load. These are designed to give users deeper insights into their overall wellness.
- Antioxidant Index: This metric estimates the level of antioxidants in the body, which can help users understand their recovery status and oxidative stress levels.
- Vascular Load: This measures the stiffness of blood vessels, a key indicator of cardiovascular health. Over time, tracking this can help users spot potential issues early.
However, in the United States, these features are being swapped out for Blood Pressure Trend. This feature allows users to monitor their blood pressure over time, providing a more comprehensive picture than single readings. It’s a notable distinction that highlights how Samsung tailors its health offerings to meet regional regulations and user needs.
Beta Update Details
The One UI 9 Watch beta update is a hefty download, coming in at approximately 1.9GB. The firmware version ends in ZZI1, which is the identifier for this particular beta build. Given the size, users are strongly advised to connect their watch to a Wi-Fi network and ensure it has at least 50% battery before starting the installation.
To join the beta, users need to be registered in Samsung’s Members app. Once enrolled, the update will appear over-the-air (OTA) in the watch’s settings menu. Samsung has not yet announced a timeline for the stable release, but typically, beta programs run for several weeks before a public rollout.
Compatibility and Availability
This beta is specifically for the Galaxy Watch7 and Galaxy Watch Ultra. If you own either of these devices, you’re eligible to participate, provided you have a compatible Samsung smartphone. The beta is rolling out in select markets first, including South Korea and the US, with other regions likely to follow in the coming days.
It’s worth noting that the Galaxy Watch8 series received the beta last week, so Samsung is clearly iterating quickly across its current lineup. This staggered approach allows the company to gather feedback from a broader user base before finalizing the software.
How to Install the Beta
If you’re eager to try out the new features, here’s a step-by-step guide to get you started:
- Open the Samsung Members app on your paired smartphone.
- Look for the One UI 9 Watch beta banner and tap “Join” or “Register.”
- Once registered, go to the Galaxy Wearable app on your phone.
- Navigate to Watch settings > Software update > Download and install.
- Follow the on-screen prompts to complete the installation.
Remember that beta software can contain bugs and might affect battery life or performance. It’s always a good idea to back up your watch data before proceeding.
What Users Can Expect Next
Samsung is likely to release subsequent beta builds with bug fixes and optimizations based on user feedback. The company has a history of refining its software through multiple beta iterations before the stable release. For now, early adopters can enjoy the new UI and health features, while providing valuable input to shape the final version.
The stable One UI 9 Watch update is expected to arrive later this year, bringing these features to a wider audience. Until then, the beta program offers a sneak peek into the future of Samsung’s wearable ecosystem.
