          • Even though Samsung Galaxy phones are already receiving the latest Android 7.0 Nougat OS, it is only happening to the 2016 flagship phones.

            Both Samsung Galaxy S7 and S7 Edge are already receiving the latest Android 7.0 Nougat OS update. However, not all regions have received the OS just yet. While S7 and S7 Edge users who haven’t received the Nougat update are still sure that the OS will come their way sooner or later, there are some who use Samsung Galaxy phones and tablets yet they have no idea if or when their devices will be updated to the new OS.

            If you are one of those who owns a Samsung Galaxy device other than the two Galaxy S7 and S7 Edge phones, there’s nothing to worry about because we’ve got your back. Here, you’ll find a list of all the devices that Samsung will update to Android 7.0 Nougat before the end of this year. The list has been sourced from Samsung Turkey’s official support page and while the release dates may represent the local Turkish market, they give us an idea of when to expect the update from the Korean company.
