Samsung has expanded the rollout of the One UI 8 Watch update for the Galaxy Watch4, extending availability beyond South Korea to India and the US.
Samsung released the update for the Galaxy Watch4 in South Korea around two weeks ago. The latest expansion means users in additional markets can now access the new software, although the rollout remains limited to the non-cellular variant of the smartwatch.
The One UI 8 Watch update for the Galaxy Watch4 carries firmware version R860XXU1JYK4 and includes the October 2025 security patch.
Users in India and the US who have not yet received the update can manually check for it by opening the Galaxy Wearable app and navigating to Settings > Software update.
Samsung has not yet confirmed when the update will be released for the LTE version of the Galaxy Watch4 or when it will reach additional regions.
