Wear OS 4 debuted earlier this month on the Samsung Galaxy Watch 6, and now it’s coming via a One UI 5 Watch update to the Galaxy Watch 5 series in the US. In a nutshell, Wear OS 4 adds cloud backups and supposedly improves battery life. (Meanwhile, you can read about the One UI 5 Watch updates here.)
Right now, it appears this is limited to the Galaxy Watch 5 series though 9to5 Google says it’ll also come later to the Galaxy Watch 4 watches. We just don’t know how much later.
