With the release of Android Nougat 7.0 for beta testers and soon customers, Nextbit Robin beta testers are now turning their attention to Nougat 7.1.1 testing. Beta testers were informed today that the 7.1.1 build would soon be pushed to their registered devices in the closed beta, with emphasis on bug fixing and testing out of features specific to that build. Part of the good news for beta testers is that the build will also have the March Android Security Update.
At this point, if you are a Robin owner, it is difficult to get into the beta program but not impossible. You can find out details about the program in this post in the Nextbit Community forums.
