As expected, the One UI 3.0 beta is now available in South Korea for the Galaxy S20, S20+ and S20 Ultra. You can join through the Samsung Members app, though note that there is a limited number of spots for beta testers available. Users of SIM-free phones and those on the major carriers (SKT, KT and LGU+) are welcome to join.
Those who join will experience Android 11 enhanced with a long list of One UI changes. Version 3 brings improvements to every corner of the software, from the Always On Display to the Internet browser, from DeX to accessibility features.
Be warned though, the list of known issues is pretty long. That’s to be expected with beta versions, participants will let Samsung know when a particular issue has been resolved so it can move on to the next.
Some apps won’t run at all, at least not with the initial version of the One UI 3.0 beta. If one of these is essential to you, you should wait for the stable version. Note that you can cancel your membership in the beta program and roll back to the current stable software (just be sure to back up your data first).
Apps incompatible with the first One UI 3.0 public beta for the S20 phones
You can follow the Source link for instructions on how to join and a list of frequently asked questions. Samsung says it’s difficult to predict when the One UI 3.0 update will be finalized as it needs to check (and potentially fix) compatibility with a great variety of apps.
The beta testing program should expand to the US (and probably Europe and India) soon, though that might take a couple of weeks.
