Stable One UI 4 update for Galaxy Z Fold3 and Z Flip3 has started again

Samsung has relaunched its stable One UI 4 release for the Galaxy Z Fold3 and Z Flip3 in South Korea. As a reminder, the update has been postponed for early adopters to report numerous bugs and bad usability. The new build comes with a BUL4 build number and is said to have ironed out all accidents from previous releases.

South Korean fold and flip users will once again act as sock testers for the latest build, and if all goes well, the release will spread to other regions. When and if the update arrives on your device, it's always a good idea to back up all your data in case you have any problems.
