Samsung launched the One UI Beta program for Wear OS last month to give Galaxy Watch 4 users a chance to experience the next major software release on their devices before the stable rollout. The first One UI Watch 4.5 beta build for the Galaxy Watch 4 series included several new features, including a new unified composer, seamless keyboard/handwriting/voice input support, dual SIM functionality, a revamped alarm setting, and much more. The Korean OEM is now rolling out the second One UI 4.5 beta update to the Galaxy Watch 4 and the Classic variant, and it brings several bug fixes and a few additional changes.
According to a recent post on Samsung Community forums, the second preview build of One UI Watch 4.5 has already started rolling out to beta participants. The update (software version R8**XXU1ZVF5) brings a bunch of bug fixes and performance improvements. The complete changelog is as follows:
