A couple of Nougat-powered Samsung smartphones - Galaxy A3 (2017) and Galaxy J7 (2016) - as well as a tablet (Galaxy Tab A 8.0) have been certified by the WiFi alliance, suggesting that Android 7.0 update for these devices is coming soon. Both phones running Android Nougat have already been spotted in benchmark listings. So what's new here is that the the tablet from 2015 will also be updated to Android 7.0 soon. There's currently no information on exactly when these updates will start rolling out, but all the signs point to a imminent release. Source 1 2 3 | Via
