Samsung is using a custom skin on top of Google’s stock Android called One UI. Not only does it change the overall look and feel of the devices, but it also introduces a bunch of features that Google’s stock iteration lacks. Android 10-based One UI recently arrived for the Galaxy S9 duo, and there have been rumors that One UI 2.1 – the ROM that the Galaxy S20 shipped with – would also be coming at some point.

Unfortunately, a recent report via the Samsung Members app in South Korea has put a stop to the rumor. According to the report, Samsung is not currently working on One UI 2.1 for its 2018 flagships, and a future release seems unlikely.
