Do we know this for a fact? Has it been measured?
.46 mm (s7) vs .67mm (6/6s)
someone can correct me if I'm wrong, small difference but it is "more flush" on the s7
I don't think it's a big deal either way (matter of personal preference)
Both phones are well designed imo, and I think it's fair for those who are a fan of the Galaxy design to champion it for its strong points. It is sort of a spiritual successor to the 4/4s design many people enjoy (glass front/back) and it curves very nicely into the hand. Don't forget it houses a large battery and also limited bezels which are arguably more attractive than the iPhone
I personally like the iPhone 6/6s design so I'm not too bothered by it. I never once picked it up wishing the bezels were smaller, to be honest.
But people should give Samsung credit where it's due; they designed some great hardware.
both phones are great, with people not giving either Apple nor Samsung enough credit for the positive aspects of their respective phones.
