Samsung Galaxy Watch8 Beats Out with One UI 9 Beta

Samsung has opened the One UI 9 Watch beta for the Galaxy Watch8 and Watch8 Classic in South Korea and the US. The ~2GB update includes the August 2026 security patch, new UI tweaks, and features; enrollment is via Samsung Members.

Want the latest watchface and a handful of fresh features before everyone else? Samsung just flipped the switch on the One UI 9 Watch beta for the Galaxy Watch8 lineup, and if your watch is in South Korea or the US, you can sign up today.

Two firmware tracks are rolling out: the South Korea build carries versions L320XXU2ZZH3 and L320OXM2ZZH3, while US testers will see L330XXU2ZZH3 and L330OXM2ZZH3. The download is not tiny—expect roughly a 2GB package—and it bundles the August 2026 security patch alongside interface tweaks and new feature additions designed to polish everyday wearables use.

Curious what changes are hiding in the update? Think smoother navigation, visual refinements and subtle usability touches rather than headline-grabbing features. These betas tend to lay the groundwork for the public release, ironing out quirks and gauging feedback from real users on real wrists.

Enrollment is handled through the Samsung Members app and is available only to eligible users in South Korea and the United States.

If you plan to join, make sure your Watch8 is paired and charged, and have a bit of patience—beta firmware can be a little bumpy, but it’s the fastest route to experiencing Samsung’s next wearable iteration.

Want in? Open Samsung Members, check the beta banner in your region, and decide whether you want to test the waters or wait for the wider rollout. Either way, the Watch8 series is getting a noticeable polish this month.
