Overview
- Samsung has opened a Wear OS 7 One UI 9 Watch beta for the Galaxy Watch 8 series that is currently available only in South Korea through registration in the Samsung Members app.
- The Watch 8 beta is about 2.01GB, includes the August 5, 2026 security patch, and brings sleep, health and Samsung Health improvements plus Google Gemini features such as Raise to Talk where the watch hardware supports them.
- One UI 9 (Android 17) Beta 7 is rolling to Galaxy S26, S26+ and S26 Ultra globally and adds AI features like My FanCam, improved Now Brief cards, and several Galaxy Z Fold 8 features including Call Brief and Fan Cam.
- Samsung is deploying these updates in phases and has not given firm dates for wider watch rollouts or stable One UI 9 releases, with eligibility and advanced AI functions likely limited by each device’s RAM and chipset.
- The moves are part of a broader mid‑cycle push to backport new software across phones and watches so users of recent devices get expanded health and AI tools sooner while Samsung completes testing and regional rollouts.
