The Galaxy Watch 6 series was launched last year with Wear OS 4 onboard. Before the end of this year, the smartwatch could get a major update in the form of Wear OS 5.
Galaxy Watch 6 could get Wear OS 5-based One UI Watch 6 update later this year
It has been revealed by @MatthewReiter05 that Samsung has started developing a new firmware version (R965USQU1BXD8) for the Galaxy Watch 6, the carrier-locked smartwatch for the US market. The firmware version appears to bring a major One UI version change, and it could be One UI Watch 6, based on Wear OS 5.
Google has already revealed by @MatthewReiter05 that it will unveil Wear OS 5 and its features at the Google I/O 2024 event in the next few days. A few months after the announcement, Wear OS 5 will likely be available in stable form, and Samsung could soon release the stable One UI Watch 6 based on that platform.
It isn't clear what new features and UI design improvements Google plans to bring with the Wear OS 5 update. From our point of view, it should bring improved integration with Android-baed smartphones, tablets, and TVs.
