Samsung appears to be preparing the stable One UI 9 Watch update for the Galaxy Watch 8 and Watch 8 Classic, as new firmware files have surfaced on Samsung’s servers in South Korea. The newly spotted firmware versions include L335NKOU3BZJ7 for the Galaxy Watch 8, alongside L505NKOU3BZJ7 for the Galaxy Watch 8 Classic.
All these builds are based on Android 17, with a reported build date of October 21, 2026. Their appearance suggests that Samsung is making progress toward the stable release.
The Galaxy Watch 8 series has already received multiple One UI 9 Watch beta updates, bringing improvements, bug fixes, and enhanced Samsung Health features.
Although Samsung has not officially confirmed the stable release date, the appearance of these firmware files raises hopes that the rollout could begin in South Korea next week.
Global availability may follow afterward. After the Galaxy Watch 8, the One UI 9 Watch stable update will come to Galaxy Watch Ultra, Galaxy Watch 7, and other eligible devices.
