While it may not be dramatically different from its predecessor, the flagship Samsung Galaxy S4 is very much a statement device. Currently one of the highest-specced quad-core Android smartphones in the market, the GS4 improves on the Galaxy S3 with a boatload of innovative software features, an improved 13-megapixel camera, IR blaster capability for controlling TVs and cable boxes, the ability to carry on ad-hoc WiFi file sharing, a gamut of sensors geared towards health apps and much more. It also feels better constructed and features a higher capacity battery.
