At the moment, we are focussing the beta programme on gathering feedback from our S10 range to collect user feedback to make sure we can deliver the best experience with the new Operating system on its official release. As soon as this will get available you will be notified. Please do keep an eye on our Social Media channels, Members app and Newsroom Page: https://news.samsung.com/uk/ for the latest information.
there's a website saying s9, s9+, and note 9 beta will start next week in Korea first then gradually release to different countries, starting November 24, 2019.
The Note 9 beta just dropped, so going by the dates posted on the korean members page, the S9/S9+ should follow in the next week or so 🤞
