I actually prefer the more muted colors. The S7 seems over saturated in some cases to me.
OP did you use all auto settings or did you tweak some settings, when I had my S7, it seemed heavy handed on the exposure settings compared to my Iphone ? Of course it could still be adjusted to compensate and is a MUCH better camera overall. There is no way the camera doesn't beat Apples camera, I switched for other reasons. I wish I could have the S7 camera on my Iphone !
