Samsung unveiled the Galaxy S4 Thursday afternoon in a quirky announcement, but there's nothing silly about the smartphone's specs. Here's how the Galaxy S4's hardware stacks up against its predecessor, the Galaxy SIII, and its main rival, the iPhone 5.
The GS4's 5-inch screen is slightly larger than the GSIII's 4.8-inch, but the real difference is in the resolution. The GSIII's screen supports 720p HD and a 306 pixel density while the GS4 can support full 1080p HD and has a much higher 441 pixel density. The iPhone 5, meanwhile, has a 4-inch screen with a less-than HD 1,136 by 640 pixel resolution and 326 pixel density.
Of the bunch, the iPhone 5 is the thinnest phone at 0.3 inches. That's followed by the 0.31-inch thick GS4 and the 0.34-inch thick GSIII.
The iPhone 5 is also the lightest at 0.24 pounds. The GS4 is second at 0.28 pounds and the GSIII is slightly heavier at 0.30 pounds.
