2016 has a better resolution( 7.0 has 720p, this one is a weird 768x1024, 10.1 has 1080p with the 2015 has the same resolution of 768x1024), better camera too. Battery slightly lower but the non-constant research for the S-Pen makes it equal.
The processor also gives it’s best at the same time. Camera quality is good. Play music anywhere you go with your Samsung earphone. Earphones quality is supreme and gives better sound quality. Enjoy net on wifi or Mobile network. Get connected to social media always.
