Samsung's One UI Watch 6 beta is now accessible for the Galaxy Watch 5 and 4 series, not just limited to the Watch 6. The beta introduces improvements in health tracking and functionality, with Galaxy AI enhancing sleep insights for users. A new pinch gesture feature enhances screen accessibility, allowing for easier navigation. The availability of the beta to Watch 5 and 4 users in the US expands beyond the initial exclusivity to the Watch 6. However, LTE models of the Watch 5 and 4 are excluded from the beta. Users can access the beta through the Samsung Members app by joining the program for their specific watch model. This release precedes the unveiling of the Galaxy Watch 7 and Watch 7 Ultra models, which will come with One UI Watch 6 pre-installed. Samsung is offering a promotion where users can reserve a $50 credit towards the new devices, with a chance to win $5,000 upon registration.
