Samsung Galaxy Watch 7 & Ultra Get One UI 9 Watch Beta
Samsung Launches One UI 9 Watch Beta for Galaxy Watch 7 and Watch Ultra
Published: Friday, September 4, 2026
Samsung has officially opened the One UI 9 Watch beta program for the Galaxy Watch 7 and the original Galaxy Watch Ultra, marking the latest expansion of its software testing initiative. The announcement, made on September 4, 2026, confirms that the beta is rolling out first in South Korea, with a US launch expected shortly.
This development comes just one week after Samsung released the same beta for the Galaxy Watch 8 and Galaxy Watch 8 Classic, signaling a rapid rollout of the company's next-generation wearable operating system.
What's New in One UI 9 Watch
The One UI 9 Watch beta is built on Wear OS 7, Google's latest platform for smartwatches. According to SamMobile, the update introduces several key health and interface enhancements:
- Antioxidant Index support: A new health metric that measures the body's antioxidant levels, providing users with insights into their overall wellness.
- Vascular Load monitoring: A feature designed to track vascular health, potentially offering early indicators of cardiovascular strain.
- Refreshed user interface: Samsung has implemented a slightly updated design language, though specific visual changes have not been detailed.
- New widgets: Additional customizable widgets for quick access to health data and app functions.
It is important to note that these features are currently exclusive to the beta program and may undergo changes before the final public release.
How to Join the Beta
Samsung is making the One UI 9 Watch beta available exclusively through the Samsung Members app. Users in South Korea can sign up immediately, while those in the United States are expected to gain access in the coming days. No other regions have been confirmed for the beta program at this time.
To participate, Galaxy Watch 7 or Galaxy Watch Ultra owners should open the Samsung Members app, navigate to the 'Notices' section, and look for the One UI 9 Watch beta registration banner. Once enrolled, the beta update will be delivered over-the-air (OTA) to the registered device.
Broader One UI 9 Beta Ecosystem
The wearable beta is part of a much larger One UI 9 testing wave across Samsung's device lineup. In the past 48 hours alone, Samsung has also opened beta programs for:
- Galaxy A36 – One UI 9.0 beta (announced September 3, 2026)
- Galaxy A57 5G – One UI 9 beta reportedly rolling out in India (September 3, 2026)
- Galaxy Z Fold 6 and Flip 6 – One UI 9 beta in South Korea (September 3, 2026)
- Galaxy Z Fold 7 – First One UI 9 beta released (September 2, 2026)
This aggressive beta rollout suggests Samsung is aiming for a stable One UI 9 release across its ecosystem by late 2026, though no official timeline has been provided.
Device Eligibility and Limitations
The One UI 9 Watch beta is currently limited to two specific models:
| Device | Launch Year | Beta Status |
|---|---|---|
| Galaxy Watch 7 | 2024 | Beta available (Korea, US soon) |
| Galaxy Watch Ultra | 2024 | Beta available (Korea, US soon) |
| Galaxy Watch 8 | 2025 | Beta available since late August 2026 |
| Galaxy Watch 8 Classic | 2025 | Beta available since late August 2026 |
Older models such as the Galaxy Watch 6 series or Galaxy Watch 5 have not been mentioned in any official beta announcements. Samsung has not disclosed whether these devices will receive One UI 9 Watch at a later date.
What This Means for Users
For Galaxy Watch 7 and Watch Ultra owners, the beta program offers an early look at Samsung's vision for wearable software in 2026 and beyond. The addition of Antioxidant Index and Vascular Load monitoring suggests Samsung is doubling down on advanced health metrics, potentially positioning its smartwatches as serious tools for proactive health management.
However, beta software comes with inherent risks. Users should expect potential bugs, reduced battery life, and app compatibility issues. Samsung recommends backing up all data before installing the beta and advises against using it on primary devices if stability is critical.
Looking Ahead
With the One UI 9 Watch beta now live for four of Samsung's most recent smartwatches, the company appears to be on track for a stable release before the end of the year. The final version is expected to bring further refinements to the user interface, additional health features, and deeper integration with Samsung's broader ecosystem of Galaxy devices.
As always, SamMobile will continue to monitor the beta program and provide updates as new information becomes available. For now, eligible users in South Korea can begin testing, while US users should keep an eye on the Samsung Members app for their invitation.
