Samsung Galaxy S4

How do you improve one of the most popular Android phones on the market? If you're Samsung, you add a wealth of extra software features and a bigger and better screen, but keep largely the same design. This is the Samsung Galaxy S4. The Samsung Galaxy S4 was first available for purchase on April 14, 2013.

Put the Samsung Galaxy S4 next to the Galaxy S III and you'll be hard pressed telling the difference. Samsung has kept much of the design the same and only small details have changed. The company obviously feels that the familiar look and feel will immediately resonate with Galaxy S III owners, but we would have appreciated a fresh new look.

The design changes on the Galaxy S4 may be minimal but most of them are welcomed. Gone are the curved, back edges of the Galaxy S III, replaced by flat edges and a smaller bezel. The sides of the Galaxy S4 feel much better than the Galaxy S III as they're flatter and squarer. The Galaxy S4 is also thinner and lighter than the Galaxy S III despite a larger screen, so Samsung definitely deserves credit for managing to slim down the case.
