2016 Samsung Galaxy J7 is the first J-series smartphone model to receive two major Android updates. At the end of August last year, he got the Android 7.0 Nougat Update that was donated, now following the update for Android 8.1.0 Oreo.
That Samsung Galaxy J7 2016 Android 8.1.0 update Oreo is coming already known. However, that is a little surprising now, because it's now faster than expected. In December or even as early as 2019, the update is expected.
