Meet the Samsung Galaxy S4 Google Play Edition: Samsung's flagship smartphone without the bells and whistles of TouchWiz. Similar to Google's Nexus line of phones, the Google Edition S4 is an unlocked device running pure, unadulterated stock Android. You get the same 5-inch 1080p display, sharp 13-MP camera and speedy quad-core processor, plus the benefit of getting software straight from Google--no carrier intervention required. However, $649 is a lot of cash to pay up front for that kind of freedom. Read on to find out if the S4 Google Play Edition is as appealing as its skinned, subsidized counterpart.
