Samsung announced the expansion on November 19, while its model-specific update record confirms a December 11 release for the Bluetooth SM-R870; availability dates varied by market, carrier, model, and paired phone.
Samsung’s schedule and the SM-R870 release record describe different things: a planned regional rollout versus a confirmed update for one model. Neither establishes a single worldwide completion date.
When did the Galaxy Watch 4 get One UI 6 Watch?
Samsung announced on November 19, 2024, that One UI 6 Watch would expand sequentially to previous-generation watches, including the Galaxy Watch 4 and Watch 4 Classic. Samsung said the Watch 6 series would receive it first, followed by earlier generations, with availability and support varying by market, carrier, model, and paired smartphone.
Samsung Canada’s schedule listed October 2024 for Galaxy Watch 4 Bluetooth versions and November 2024 for LTE versions. This was a schedule, not proof that every eligible watch received the update on those dates.

Samsung’s update history for the Bluetooth Galaxy Watch 4 model SM-R870 lists build R870XXU1IXK1, dated December 11, 2024, with the October 2024 security patch. This record applies specifically to the SM-R870 and should not be treated as a release date for every Watch 4 variant.
On December 11, 9to5Google reported that the update was expanding globally, including to U.S. variants, while noting that some regions might wait another week or two. That is contemporaneous reporting, not a Samsung confirmation that the worldwide rollout was complete.

Health and sleep information
Samsung documented Energy Score, which uses sleep and physical-activity information to provide a wellness-oriented score and personalized insights. Expanded sleep information included heart rate, respiratory rate, and time to fall asleep. Samsung describes these tracking functions as general wellness and fitness features, not tools to diagnose or treat disease.
Workout routines and Race
Users could create custom workout routines with exercise targets and optional rest breaks. Samsung also described Race as a way to compare a current running or cycling performance with a past effort, subject to usage conditions.
Watch faces and interface changes
The documented changes included the Spatial Number, Simple Digital, and Ultra Info Board watch faces, along with redesigned buttons and toggles, a refreshed default font, and updated tile-opening graphics.
Gestures, scrolling, and suggested replies
Double-pinch controls added actions for one-handed use, and scrolling through tiles and notifications became faster. Suggested replies used AI-generated response options for supported notifications. Samsung’s changelog says the feature requires a phone running One UI 6.1.1 or later that supports it. Some Galaxy AI features may also require a Samsung account; availability and support can vary.
