The One UI 9 Watch timeline
Samsung has been consistently following its own development schedule, bringing One UI 9 Watch to its devices shortly after the official unveiling of its Android 17-based operating systems. According to early reports from SamMobile , internal testing initially began for the Galaxy Watch 8 series with build version BZG2 , while corresponding builds appeared earlier for the Watch 7 and Watch 6.
Judging by the way the Korean company is doing, internal testing usually takes three to four weeks before the public beta program is given the green light.

Which models are getting the upgrade?
The One UI 9 Watch compatibility list includes most of Samsung's current lineup, starting with the Galaxy Watch 5 and going all the way up to the upcoming flagship models. The official list includes the Galaxy Watch 8, Watch 8 Classic, Galaxy Watch Ultra, Watch 7, Watch FE, Watch 6, Watch 6 Classic, Watch 5, and Watch 5 Pro.
On the other hand, the Galaxy Watch 4 series is out of the picture, as it has already completed the three-year software support cycle that the company promised. If you still have a Watch 4 on your wrist, the device will remain functional, but the new features of Wear OS 7 will definitely overtake you.
What changes in performance and autonomy
The biggest bet of Wear OS 7 combined with One UI 9 Watch is none other than power management and responsiveness. Samsung is investing in more personalized and adaptive health features, which leverage improved machine learning algorithms directly in the watch processor.
According to leaked firmware logs posted on social media by users like Alfaturk16 , the changes focus mainly on reducing battery consumption when continuously recording sleep and heart rate.

Our opinion at TechNoid
Samsung's decision to leave out the Galaxy Watch 4 is completely expected but at the same time disappointing for those who bought this model believing in its long-term promises. At TechNoid, we believe that the technical characteristics of the Watch 4 could withstand at least one more cycle of upgrades. If you own an older model, the arrival of the One UI 9 Watch is the ideal reason to look towards the newer proposals on the market.
