Samsung has started rolling out a new January 2026 software update for the Galaxy Watch 4 series, aiming to improve the overall user experience after recent system changes. Currently, the update is available in South Korea, and Samsung is expected to expand the rollout to more regions in the coming days.
This update is especially important for users who faced bugs and performance issues following the One UI 8 Watch update. Many users have reported minor glitches, lag, and stability problems, and Samsung is now addressing these concerns through this maintenance release.
The January 2026 update for the Galaxy Watch 4 carries the build version R890XXU1JYL6, as reported by Alfaturk. The update package is relatively small, with a size of around 140MB, making it quick and easy to download and install even over a mobile connection.
Rather than introducing new features, Samsung has focused this update on system optimization. According to the official changelog, the update improves device stability and enhances security. This means users can expect smoother performance, fewer bugs, and better protection against potential vulnerabilities.
Overall, this update is a reliability-focused release that ensures Galaxy Watch users get a more stable and secure smartwatch experience. Once it becomes available globally, users are advised to install it to maintain optimal performance and system health.
