The Galaxy Note 20 Ultra's new One UI 4 beta is rated for multiple bug-fixes
The Galaxy Note 20 and 20 Ultra just might be the last of their S Pen-toting line; however, they remain near the top of the list as far as Samsung's development of One UI goes. Their units can access beta builds of this Android skin's newest version in some markets.
Unfortunately, these advance public previews of One UI 4 have not worked out that well for the Note20 or its Ultra sibling thus far, resulting in several bugs including sudden-onset battery drain; the loss of fingerprint-sensor use in some apps; crashes on connected wearables of the Galaxy Watch4 series and excessively dim screens on boot.
However, Samsung asserts that these issues and more should be fixed in the latest update. This One UI 4 Beta 3 for the Galaxy Note 20 series (or software version ZUL1) has now been announced by the OEM. However, it is only available to users in the US or South Korea to date.
