Is no one seriously going to mention how BAD the 4.7" model needs an upgrade in terms of screen PPI? Compared to 4" iPhone 5S and Plus the 4.7 looks like a peasant. It was one of the reasons I decided to return it when I first bought it and go back to my 5S.
If anything, the MAIN upgrade should be a drastic bump in screen quality because its very pixelated compared to the models I mentioned.
so sad we have users here so misinformed
