Samsung has begun rolling out the long-anticipated stable One UI 8 Watch update for the Galaxy Watch7, bringing an array of upgrades that refine both performance and user experience. After more than a month of beta testing, users in South Korea are the first to confirm the arrival of this stable release, while the global rollout is expected to follow soon.
The update, based on Wear OS 6, comes with build number L310XXU1BYI4 and weighs roughly 160MB. 
It also includes the September 2025 security patch, ensuring enhanced protection and system stability. But beyond routine fixes, the One UI 8 Watch release introduces several exciting innovations aimed at usability, design, and health tracking.
The visual overhaul starts with the new Now Bar – a more intuitive way to access key functions at a glance – accompanied by refined gesture controls and smoother animations. Notifications have been improved for clarity and responsiveness, and users will notice a fresh charging animation that adds a modern touch. Samsung has also expanded its library of watch faces, offering a blend of minimalist, sporty, and data-rich designs to suit various lifestyles.
Perhaps the most talked-about changes come from the health and fitness suite. The update brings in advanced metrics such as the Antioxidant Index, Vascular Load, Running Coach enhancements, and Bedtime Guidance. These features provide deeper insights into recovery, cardiovascular strain, and sleep quality – all part of Samsung’s growing focus on holistic wellness technology. Combined with refined AI-driven tracking and real-time guidance, the Watch7 now feels more aligned with professional fitness tools while remaining accessible to everyday users.
Many owners have praised Samsung’s approach, seeing this update not as a cosmetic patch but as a meaningful leap forward in smartwatch intelligence. The One UI 8 Watch release reinforces the Galaxy Watch7’s reputation as one of the most complete Android wearables available, proving that consistent software support can truly extend a product’s value over time.
