Read full Samsung Galaxy S2 review
This phone has it all: the fastest dual-core processor, the most vibrant screen, a super slim and lightweight design, and oodles of features. It does have a couple of downsides, though. It's thinness gives it a slightly cheap and weak feel while its large height and width make it a little big for some hands. Neither does Samsung have the best implementation of Android and of course Android does still have a few quirks of its own. All told though, there's good reason why this is the biggest selling phone of the moment.
