Samsung, albeit with a slight delay, has launched the One branded shell beta program
However, so far only users from South Korea have been able to test the firmware. And even that limited number is only 1000 participants in the testing program.
But tomorrow, October 14, Samsung will open the program for other users - from South Korea, as well as the United States and Germany.
The update can be found in the Samsung Members branded application. A banner will appear there, by clicking on which, you will become a member of the beta testing of One UI 2.0.
When the final release of the firmware will take place is unknown. Most likely, it will be at the end of November - December.
