Samsung starts rolling out stable One UI 9 with Wear OS 7 to Galaxy Watch 8 series

The Galaxy Watch 9 and Watch Ultra 2 shipped with One UI 9 Watch straight out of the box. Now, Samsung is bringing its latest smartwatch software to older hardware, starting with the Galaxy Watch 8 and Watch 8 Classic. The two watches are the first to receive a stable over-the-air upgrade to the Wear OS 7-based software.

Following nearly two and a half months of beta testing, Samsung has begun rolling out the stable update in South Korea. According to reports emerging on social media, the release is reaching both beta participants and regular users, marking the end of the testing period that began in August.

Screenshots of the update confirm firmware versions L320XXU2BZJ7/L320OXM2BZJ7 for the Watch 8, a download size of approximately 2GB for non-beta users, and the October 5, 2026 security patch. The same build is also rolling out to the Watch 8 Classic.

Samsung hasn’t published a complete changelog for the stable release, but earlier beta updates offer a fairly good preview of what’s coming. Highlights include a redesigned interface, more watch face customization options, and expanded Samsung Health features, including cardio load tracking and sleep vitals monitoring. The betas also introduced improved workout controls, additional camera remote modes, and more flexible Trackback navigation.

For now, the stable update is limited to South Korea, with no confirmed release date for other markets. Galaxy Watch 8 owners can check for availability through the Galaxy Wearable app > Watch settings > Watch software update > Download and install.
