Samsung Galaxy Watch4 gets third beta of One UI 4.5 with lots of bug fixes

Testers are working on Wear OS 3.5 on the Galaxy Watch4

Samsung launched the first One UI Watch beta program for the Galaxy Watch4 last month. Until then, the program was limited to testing the next versions of One UI for its high-end smartphones and foldables. One UI 4.5 will be a significant update for the Galaxy Watch4 which upgrades the underlying Wear OS version to 3.5 and introduces several new watch faces and improvements. After rolling out two betas last month, Samsung kicked off July with the third beta version of One UI 4.5 for the smartwatch.

One UI 4.5 beta 3 for the Galaxy Watch4 fixes several bugs (via XDA-Developers) found in previous versions. This includes fixing a system UI crash when the home button was pressed while scrolling through a list and fixing an inability to restore tile backups. Touch sensitivity and power consumption have also been adjusted, hopefully more favorably for users.
