Samsung is on a pretty smooth yearly release cycle with its Galaxy S series, and each time another one hits it's a perfect time to see how far we've come from the previous generations. With the Galaxy S7 now released, we can see how its specs stack up against the Galaxy S6 and Galaxy S5. With the similarities to the GS6 and a few of the features being brought back from the GS5, it's certainly an interesting comparison.
