Spent a bit of time yesterday discovering what was changed and improved for the beta build 4, now that we're steering closer to the release.
What I recognized immediately is that the back button input is significantly faster than it was on beta 3 (personally the worst build I've ever experienced). I like the smaller details that were focused on such as the milestone notifications for Samsung Health (max steps, activity time, etc). I think we have one or two builds left until OneUI Watch 5 is officially ready for the public. I personally think all that's left is optimization because I still noticed some UI stutters when typically scrolling through tiles on the home screen, which has been an issue for quite some time. Thank you for all you have done, Samsung MX Team!!
