Samsung does have more of an open ear and open mind than Apple.
I guess they let the tech reviewers dictate their recent move after hearing all the bemoaning about how their design and build quality sucks and feels cheap. I just find it funny when a removable battery and sd slot were included, reviewers glossed right over it and only focused complaining about design and build quality. Now that they didn't include both as well as water/dust resist, the new complaints is what it doesn't have anymore!
S5 was the most underappreciated Galaxy S phone of all-time! Band-aid design and all.
But Samsung can EASILY fix this with enough complaining and feedback. Variants, variants, variants. Samsung is more sensitive to criticism than Apple. LG and HTC did the same thing in 2013 and yet nobody complained about as much as Samsung in 2015. I think Samsung can do an LG only to bring back both features in 2016 with the S7 like what LG did with the G3. If they do another S6 variant, use the same rear as ones found in the recent Notes. Make it thicker for higher batt capacity. I love that rear cover of the Note much more than another glass rear. I don't CARE if we got to Gorilla Glass 19. I want more grip and a slopey S Edge will make it slippery with a glass rear.
