It looks like Samsung has decided to change the naming strategy of its custom skin and going to discontinue the third version of the same One UI generation and Android OS from this year. It is rumored that the Galaxy Z Fold 3 will come with a new One UI 3.1.1 version out of the box.

Previously, it was expected that the company’s upcoming high-profile foldable phones will exclusively come with the Android 11-based One UI 3.5. Meanwhile, a well-known tipster claimed that there will be no One UI 3.5 and the Galaxy Z Fold 3 will come with One UI 3.1.1.
