Samsung has been working on upgrading to Android Oreo for the Galaxy S8 and Galaxy S8 + flagships in the US and UK for a long time. Today, participants in beta testing are available three assemblies of software with a “cookie” and user interface Samsung Experience 9.0, and soon there will be a fourth.
This was described traditionally by an active support service for British clients. Moreover, tech support reported the release date of the final release. According to her, this will happen in late January or early February (if there are additional difficulties).
