Samsung Galaxy Watch4 and Galaxy Watch4 Classic receive One UI Watch 4.5 Beta 3 based on Wear OS 3.5

Last week, Evan Blass shared numerous screenshots of One UI Watch 4.5, based on Wear OS 3.5. As we discussed at the time, the leaked screenshots highlighted that Samsung plans to bring full keyboard support to it smartwatch OS this summer, along with dual eSIM support. Subsequently, Samsung has released One UI Watch 4.5 Beta 3, likely one of the final beta builds before the OS debuts next month with the Galaxy Watch5 series.

For reference, Samsung notes that you can only update to the latest update via Firmware Over The Air (FOTA), rather than a desktop application. As always, you can check whether the build is ready to download on your Galaxy Watch4 by heading to the main settings menu, finding 'Watch software update' and checking for an update within that sub-menu. As the screenshot below shows, the latest update focuses on addressing bugs that exist in the second beta build. According to Samsung, it has made the following changes with One UI Watch 4.5 Beta 3:

• Improving Watchface GUI
• Fixed restore problem after Tile backup
• Fixed SysUI crash problem when pushing Home button during scrolling
• Fixed Music Bixby malfunction problem
• Improving wearing detection accuracy
• Improving usability of Alarm, Stopwatch, Timer, and World Clock
• Stabilising touch performance
• Improving power consumption caused by Buds auto switch communication
• Improving performance of automatic exercise
• Improving recognition rate of Wrist up when bicycle exercise
• Fixed BT connection problem when running gallery app
• Other improvements are applied

Additionally, Samsung has rolled out a new beta version of Watch4 Manager, now at v2.2.11.22063011. Samsung advises that you update to the latest version in the Watch plugin too, presumably before you begin downloading One UI Watch 4.5 Beta 3. Seemingly, the Galaxy Watch4 series is the test bed for Wear OS 3.5, with the Pixel Watch not due until the autumn. For some reason, Google's eponymous smartwatch could launch with a modified chipset from the Galaxy Watch3 series, potentially leaving it at a performance disadvantage compared to the Galaxy Watch4 and the Galaxy Watch5 series.
