Samsung launches Galaxy Watch 7 and Watch Ultra One UI 9 beta program

TL;DR

Samsung has started a One UI 9 Watch beta for the Galaxy Watch 7 and Galaxy Watch Ultra.

The beta is currently rolling out in Korea and should reach the US soon.

Only Korea and the US are included in Samsung’s One UI 9 Watch beta program, with signup available through the Samsung Members app.

It's raining One UI 9 betas for Samsung devices this month. After opening the One UI 9 beta program for all of its flagship phones launched in 2023 and later and a couple of mid-range devices, Samsung has now released the One UI 9 Watch beta update for the Galaxy Watch 7 and the Galaxy Watch Ultra.

One UI 9 Watch is based on Wear OS 7, and its beta version for Samsung's 2024 smartwatches comes a week after the Galaxy Watch 8 and Galaxy Watch 8 Classic received it. The new update is rolling out in South Korea and should come to the US soon — these are the only markets where Samsung is making the One UI 9 Watch beta program available.
