Finally, Samsung has opened the beta program of Android Nougat 7.0 for the Galaxy S7 and S7 Edge devices. As part of that, they have released an app named Galaxy beta program app for the United Kingdom people. You can get it on Xda Developers. It helps to receive beta builds of Android Nougat on Galaxy S7 and S7 edge devices. You can easily register on the app to get the updates.
If you are interested in testing out the builds, you can try it now. But the server of the app is offline at the moment. We hope it will be available soon for new registrations.
