Well maybe you need a magnifying glass, but the J5 (2015) is there from the start. The SG-J500F is listed to get Nougat on 1 Oct 2017 in the original road-map list
I never got Marshmallow for it via OTA updates.
How could they update it to Nougat?
But at some point I had managed to flash a Korean Marshmallow though I rolled back to Lollipop after some days.
Samsung Galaxy J5 2016 shares the same exact hardware as my Asus Zenfone Max
SnapDragon 410, 2GB RAM, 16GB ROM.
So in short, there's a possibility that my phone will get it, too, but I wish Asus will not abandon my unit.
I'm still glad that they support mine still, with the March 1 2017 security update - not the latest, but better than not, right?
