After spending a few weeks with both the 2015 and 2016 models i can say that the 2016 is a downgrade in almost every aspect. The 2015 performs better, it runs cooler and smoother. Games play at full frame rate while the 2016 model struggles in most games i tried. The 2016 model also heats up more than the 2015 one when gaming or browsing the web.
UI smoothness is better on the 2015 . Gmail for example is a stuttery mess on the 2016 model while it runs great on the older model.
Speaker are better on the 2015 model,. There is noticeable difference.
I am not sure what Samsung tried to achieve with releasing an inferior model with the same name, 8 months after the initial launch, I am honestly surprised that the 2016 models performs worse as it should have a better CPU and GPU (at least according to the benchmarks).
Hopefully an S3 is coming this year.
