AT&T's Samsung Galaxy Note 5 and S6 edge+ are now being updated to Android Nougat
According to AT&T's official Galaxy Note 5 support page - see the source link below - the new update brings Android 7.0 Nougat (not 7.1) to the handset, and includes the March security patch. Users are also getting two pre-loaded apps (Samsung Cloud and Samsung Pass), plus improvements related to network performance. Moreover, the update is removing some apps, including AT&T Address Book, AT&T Live, and MobiTV.
