Samsung Rolls Out New One UI 9 Watch Betas for Galaxy Watch 8 and Ultra
The fourth beta for the Galaxy Watch 8 series and the third for the first-gen Galaxy Watch Ultra arrive in South Korea with AOD and Samsung Health fixes.
Samsung has begun rolling out a new One UI 9 Watch beta for the Galaxy Watch 8 and Galaxy Watch 8 Classic in South Korea, alongside a separate beta for the first-generation Galaxy Watch Ultra, according to Android Authority.
The Galaxy Watch 8 and Watch 8 Classic update is the fourth One UI 9 Watch beta and carries build number ZZJ1 at 226.19MB. It brings fixes for always-on display (AOD) bugs, patches an error in the Samsung Health app and improves home button shortcuts.
The first-generation Galaxy Watch Ultra is receiving its third One UI 9 Watch beta, a 219.92MB download with a near-identical changelog covering the same AOD, Samsung Health and home button items.
