Samsung initially launched the One UI 8 Watch update for the Galaxy Watch4 exclusively in South Korea a few weeks ago. Now, the company has extended the update rollout to include India and the United States.
The update is currently available only for the non-cellular versions of the Galaxy Watch4. It arrives with firmware version R860XXU1JYK4 and includes the October 2025 security patch.
If you reside in India or the US and have not yet received the One UI 8 Watch update on your Galaxy Watch4, you can manually check for it by opening the Galaxy Wearable app and navigating to Settings > Software update.
