Samsung is resuming the rollout of the stable One UI 4 based on Android 12. Galaxy Z Fold3 and Flip3 were shut down the last week due to an incredibly irritating issue with Google Play compatibility.
Five months later, all issues have been resolved by a partnership with Google in the holiday season, and rolling outs are now back in the process. A brand new build is being distributed and is dubbed G99xBXXS3BULC for S21 models. S21 models (where “x” is a different number depending on the model of device is being used).

The Korean versions are G99xNKSS3BULC. The latest version available for Flip3 has been named Flip3, is F711xxxS2BUL6. The version of Fold3 has the code F926xxxS1BUL6 (here, it’s that the “xxx” part varies according to the region).
If you have one of the overhead devices, it is possible to check for updates manually, and you could be lucky. Like most carriers, carrier-specific models may be slower than the unlocked models.
