@temetnosce, Unfortunately Samsung doesn't provides update dates. We don't even officially know if Fold 3 will get One UI 4.1.1 or will go straight to One UI 5. Rumour has it will get One UI 4.1.1. But it is only rumor. We have to wait and see how the story develops.
@temetnosce, Samsung shared info about One UI 4.1.1 update on Newsroom. Unfortunately nothing about Z Fold series.
Android 12L will be made available for Galaxy tablets including but not limited to Tab S8 series, Tab S7 series, Tab S7 FE, Tab S6, Tab S6 Lite and Tab Active3.
One UI 4.1.1 will be extended to Galaxy Z Fold2, Z Flip and Z Fold. More info on Newsroom website
