Samsung Galaxy S2 AT&T Black 16GB (Used)

Unlike its predecessor, the Samsung Galaxy S2 is made with a dual-core 1.2 GHz processor for added power to support a large array of applications. It’s still a small phone, though, at just 4.9 inches tall, 2.6 inches wide and 0.3 inches thick.

Samsung also made the device extremely thin and feather-light (it weighs about 4 ounces). Part of the reason Samsung was able to do this is by sacrificing the classic metal feel a lot of smartphones give. A plastic back is used on this phone, though the battery covers it up.  However, the back of this battery is textured, providing a high-end feel.

The back of the Galaxy S2 is also made from a type of molded mesh that actually works to keep your hand from getting warm when you use the phone for an extended period of time. The same can be said for if you leave it on your lap while listening to music.

The display on this phone comes in at 4.3 inches, making it even bigger than the screen on the iPhone 5s. Plus, it supports super AMOLED Plus tech, meaning your eyes will immediately notice a difference, once the visuals get past the extremely durable Gorilla Glass that protects the screen. Samsung made this phone with a pixel resolution of 480×800, so 16 million different colors can be represented. Consider, too, that Plus technology further breaks down each pixel into smaller subpixels and you have a very impressive display.

There are two cameras featured on this phone. The one facing toward the front is good for two megapixels, while the one facing the back can support eight.

Speaking of visuals, Samsung’s TouchWiz 4.0 interface adds better optics to everything from photos to apps to videos.
