Multiple users on Reddit have confirmed that issues with their Galaxy Watch 4 or Watch 4 Classic have resolved. The Galaxy Watch 4, Samsung’s first smartwatch running Google’s Wear OS, launched more than four years ago. And so when Samsung released the One UI 8 Watch update for Galaxy Watch 4 and 4 Classic, it felt like a special, heartfelt farewell. Their post also includes a screenshot of the Galaxy Watch diagnostics tool, confirming that all sensors are functioning properly. In the app, go to Watch settings > Watch software update > Download and install.
