The answer is unfortunately not set in stone, and will vary from not only model to model, but carrier to carrier. Updates are slowly released by the carriers as they make sure of compatibility. Because there are other channels besides Samsung it has to go through first, no set dates can be given, however, all eligible devices will have the opportunity to get it. Any questions regarding a release date should be asked of your carrier. This applies to both locked and unlocked phones.
Samsung has started to roll out One UI 6.0 for the S23 Family and the update will start reaching consumers across the US soon. One UI6.0 will continue to expand to other Galaxy S22, S21, Fold5/Flip5, Fold4/Flip4, Fold3/Flip3, and A54 before the end of the year (note, this is a tentative time frame and everyone should still check with their carriers on exact dates).
