One UI 9 Watch Beta Expands to Galaxy Watch7 and Watch Ultra
Samsung is broadening its testing phase for the upcoming software iteration, extending the Wear OS 7-powered One UI 9 Watch beta to the Galaxy Watch7 and the rugged Galaxy Watch Ultra. This rollout follows the initial beta launch for the Galaxy Watch8 and Galaxy Watch8 Classic, signaling that the company is accelerating its software development cycle to ensure a stable public release.
What’s New in the Latest Beta Build?
The update, identified by firmware version ZZI1, is a substantial download at approximately 1.9GB. Beyond the standard performance optimizations, it integrates the September 2026 security patch, reinforcing the device’s defense against emerging vulnerabilities.
Users can expect a modernized interface aesthetic alongside a suite of functional enhancements. Key health-tracking additions include:
- Antioxidant Index: A new metric designed to help users monitor their body’s oxidative stress levels.
- Vascular Load: A feature providing deeper insights into cardiovascular health.
- Regional Adjustments: In the United States, these specific health metrics are being swapped for the Blood Pressure Trend feature, likely due to local regulatory requirements.
Availability and Enrollment
Currently, the beta program is restricted to users residing in the US and South Korea. For those eager to test these features ahead of the general public, participation is managed through the Samsung Members application. By enrolling via the app, eligible owners of the Galaxy Watch7 or Watch Ultra can receive the over-the-air update directly to their wrist.
Market Context
As wearable technology continues to evolve, the integration of advanced biometric sensors-like those found in the Watch Ultra-has become a primary differentiator. With the global smartwatch market projected to maintain steady growth, Samsung’s commitment to frequent software updates is a strategic move to maintain user retention and compete with rival platforms.
