Shortly after the Galaxy Watch Active2 and Galaxy Watch3 received an update unlocking the ECG feature for the European countries, Samsung is now delivering Galaxy Watch3-intrinsic features to the original Galaxy Watch and Watch Active.
So far, the update is being distributed to the US and Korean owners but it will likely go global soon enough. The original Galaxy Watch bumps up the firmware version to R810XXU1FUB6 while Active2 is getting R500XXUF1UB5. Both are now running Tizen 5.5 as opposed to the Tizen 4.0 when they were first released.
The new features in question are support for AR Emoji and Bitmoji, images appear on your notifications, voice guidance for cycling and running, continuous scrolling screenshots and guidance over Bluetooth-connected headphones. Of course, other stability and performance improvements are also at hand.
