For some time now, Samsung has been the dominant player in the Android space, especially at the high end of the market. From the Galaxy S2 onwards, Samsung has been able to ride the wave of the smartphone industry’s growth without much disruption. Samsung has also shown a pretty impressive ability to adapt to changes in the market as seen by their dramatic departure in materials from the Galaxy S5 generation to the Galaxy S6 generation. While the Galaxy S6 was ultimately one of the best phones you could get that year, at least a few design decisions like the loss of removable battery and microSD slot were generally considered to be a step back relative to previous devices.
Throughout their reign of dominance Samsung has always been able to stay on top, however their competition is never too far behind. To that end, it’s probably obvious now that the Galaxy S7 family represents an attempt to improve on the Galaxy S6’s perceived faults, while building upon its perceived strengths.
