The next smartphone to receive the beta test of Android Nougat 7.0 is Nextbit Robin. Since it is a Beta Version only a certain number of people who have registered online would be receiving the update. The registrations are still open. However Nextbit warns, "if you have modded your phone in any way, it is not recommended that you update."
Nextbit has worked closely with the developers behind the very popular Paranoid Android custom ROM to bring Nougat to the Robin. There has been an immense exchange of ideas, code and resources which made the process faster, smoother and better.
The beta Nougat version has all the goodies of the Google Android 7.0 Nougat but keep in mind that since it is a beta version there are bound to be a few glitches until the actual update is released.
