Samsung releases Wear OS 6-based One UI 8 Watch update for Galaxy Watch 4 and Watch 4 Classic. It’s the last major upgrade for the company’s first-generation Wear OS smartwatch lineup.

Wear OS 6 update’s arrival wasn’t anticipated for the Galaxy Watch 4 models. These smartwatches have already completed their software updates support in August 2025; however, Samsung hasn’t ousted the devices.

While releasing the One UI 8 Watch, Samsung officially confirmed to provide the update to the Galaxy Watch 4 and Watch 4 series. As promised, the rollout has begun in 2025 itself, but the expansion will take some time.

Users of the Watch 4 and Watch 4 Classic in South Korea can identify the latest update through the PDA version number JYK4. The firmware also brings newer security patches that elevate the reliability of the smartwatch.

The rollout has just started in Korea, with Global availability anticipated by the end of this month. As of December, Watch 4 series is still listed to receive new software updates, but it’s unlikely to last much longer after One UI 8 Watch.

With the One UI 8 Watch, Galaxy Watch 4 users receive Tile System, watchface enhancements, and Mindfulness as key features. Now Bar is also provided that Samsung hasn’t highlighted even though it’s a significant development.

One UI 8 Watch is based on Wear OS 6, which is another advantage. The new operating system improves support for third-party apps. You can expect a better experience and faster app launches due to core optimizations.

Samsung Wearable is the key to getting the latest update through your Galaxy phone. You can also trigger an update right from the watch. Swipe up and open Settings, followed by Software update and Download and install.
