The update is available for Galaxy Watch4 and Watch4 Classic users in South Korea and the USA, provided you’re already enrolled in the beta program. In that case, you should receive an OTA notification to install it on your device soon. You can also check for it by navigating toGalaxy Wearable > Galaxy Watch4 > Watch4 settings > Watch software update > Download and install.
Unfortunately, if you’ve not previously joined the program, there’s no way to access it currently, as the company has put a hold on beta sign-ups (per9to5Google). Meanwhile, there’s still no way to downgrade to the last stable release should you decide to leave the program midway.
