Surprise One UI 8 watch update revives legacy Galaxy Watch

Technology Jul 11, 2025

Samsung just dropped the One UI 8 Watch update for Galaxy Watch 4 and Watch 4 Classic—even though most people thought these models were done getting big upgrades.
The update is built on Wear OS 6 and brings fresh features to keep things interesting.

New tools and features for Galaxy Watch 4

Galaxy Watch 4 users now get Bedtime Guidance, Running Coach, and Vascular Load tools—though some perks like the Antioxidant Index are still exclusive to newer watches.
There's also a redesigned interface for smoother navigation.
This marks the fourth major update since launch, letting users enjoy new functions without rushing out to buy a new watch.
It's a nice move from Samsung, showing they haven't forgotten about older devices.
