Samsung Galaxy S7
The Samsung Galaxy S7 finds itself in a slightly tricky situation. Samsung needed a big win from the Galaxy S6 in 2015, which it got after reinventing the design of its flagship smartphone, but you're not going to get the same degree of evolution again just a year later.This means the Galaxy S7 falls firmly into the iterative camp, building on the solid foundations laid by its predecessor without fiddling with the winning formula too much.
