So how do you get access to this program? You can do this by going to the Galaxy Apps store on your phone - if like me you disabled it, then make sure you enable it again and update the app - then search for Galaxy beta program. Install the app because you will need to use it to register for the program.
Samsung intends to run this program from 9/11/16 to mid December in the UK, you should expect the latest Samsung UX based on Android 7.0 (Nougat). The programme is only open to Galaxy S7 / Galaxy S7 Edge and both devices have to be unlocked and network free versions. The Olympic and Batman editions are not supported.
To register for the programme you need to open the app and click the settings menu - the three vertical dots - and press the Registration option in the popup menu, this will take you to the Terms of Service for the programme, agree to it and it will register you with the Beta programme. You will need to have a Samsung account to be able to take part.
If you want to leave the program you can open the app again and click on the settings menu and choose deregister, this will remove you from the beta programme. As with any beta software, this will likely have bugs, so if you are updating your main driver ensure you backup your device first.
The instructions say that to download the beta software you will need to go to Settings - About device - Download updates manually to be able to download the software. It seems this hasn't gone live yet, once it has we will have more information to share.
Let us know how you get on with the program and share your feedback with the rest of the community here at MoDaCo.
