Not all Samsung Galaxy S7/Galaxy S7 edge models will get the latest Android Nougat build at first
Samsung hasn't explained the reason for the separate update paths it is taking, and Australian Galaxy S7/ Galaxy S7 edge owners are getting the short end of the stick; the Android 7.0 update doesn't include some fixes that are found on Android 7.1.1.
One Galaxy S7 or Galaxy S7 edge owner, who presumably lives in Australia, summed things up pretty accurately on the Vodafone community board. "Hmm that's odd... and unfair," she said.
