Samsung users are waiting for a new version of Android system for their phones. As reported by beta testers, they received a few days ago the fifth beta version of Android Nougat for Samsung Galaxy S7 and S7 Edge. This is the last beta before the release of the final version of the system.
It's not known if Samsung decides to immediately upgrade to version 7.1.1 of Android, or only to version 7.0. More reports from beta testers indicates that they only tested version 7.0.
