Samsung Galaxy S II (AT&T) is more compact and a great camera and fast data speeds.

The AT&T Galaxy S II is the runt of the Galaxy S II litter. Its version has "just" a 4.3-inch Super AMOLED screen. It has a slightly smaller screen than its siblings, the AT&T S II is also about an eighth of an inch shorter, measuring 5 x 2.6 x 0.4 inches, and, at 4.1 ounces, nearly a third of an ounce lighter. In the middle of casually handling the phone, necessitating us to hit it again to turn the handset back on. The 3.5mm headphone jack is on the top right and the volume toggle on the left spine is a single switch.

The 800 x 480 Super AMOLED display on the AT&T Galaxy S II is smaller than its siblings. Lightmeter, it registered 213 lux for the AT&T S II and 286 lux for the Sprint model. Samsung's TouchWiz overlay includes some neat Live Panel widgets, such as Picture Frame. Like the Sprint Galaxy S II Epic 4G Touch, the AT&T Galaxy S II uses a 1.2-GHz Exynos C210 processor. Considering we're still dealing with a plastic pinhole lens, the Galaxy S II takes shockingly colorful, bright and crisp 8-megapixel.
