Samsung releases a One UI 9 Watch beta for owners of the Galaxy Watch8 and Galaxy Watch8 Classic, offering early access to new watch software. Outlets report the beta is available to users in both the US and South Korea.
The beta runs on specific firmware builds—listed as L320XXU2ZZH3/L320OXM2ZZH3 for South Korea and L330XXU2ZZH3/L330OXM2ZZH3 for the US. The update is reported to be about 2GB. It includes the August 2026 security patch and adds visual and functional upgrades to the watch interface and features, according to coverage from multiple outlets.
While one report emphasizes that US Watch 8 owners can “take One UI 9 Watch for a spin,” other coverage frames the release as Samsung opening the beta program in those regions. Both agree the rollout is limited to the Watch8 generation and requires enrollment or participation in Samsung’s beta process.
