One UI Watch 6, now featured on the Galaxy Watch 6, is being extended to the Galaxy Watch 5 and Watch 4 models. This allows users of these older devices to access Samsung's newest software.
Beta Release Details
At present, this update is in the beta phase and isn't available for all Watch 5 and Watch 4 models. The One UI Watch 6 beta is restricted to the Bluetooth versions of these watches. Those with LTE variants will have to wait a bit longer.
Future Expectations and Update Process
Many anticipate Samsung will soon launch the Watch 7 series. Meanwhile, it's encouraging to see Samsung updating its older models. Recently, the Galaxy Watch 6 Classic LTE hit its lowest price point ever.
To get the new update, use the Samsung Members app. Open the app on the phone linked to your watch and look for the beta release for the Watch 5 or Watch 4. If the update isn't visible yet, remain patient, as Samsung is deploying it in stages. It might take a while for all devices globally to receive the update.
