Samsung’s Galaxy S4 is truly a successor to the S3. Almost identical in design, the S4 is lighter but has a bigger screen, more power and a longer list of innovative features.
Samsung could have changed the polycarbonate shell and design to give it more premium look and feel. But, perhaps as the S3 was the bestselling smartphone last year, Samsung did not want to fiddle too much with a winning design. Instead, the bezel on the S4 has been shrunk to increase the size of the display and, at 130 grams, it is just three grams less than S3.
