Just want to inform you that One UI 2.0 is still not yet available here on UK. Our developer is still working on beta programme. At the moment, Samsung has launched the OneUI 2.0 Beta is available in selected markets and will be coming soon to other countries. To deliver the highest quality update at general release, Samsung is gathering customer feedback from those on the Beta to drive improvements to the latest Operating System.
