The Nokia 5800 shares design characteristics with the iPhone and Samsung touch-screen handsets like the Omnia. The candy bar shape offers clean lines with rounded corners and a black and burgundy color scheme (there's also a thin red stripe). At 4.37 inches tall by 2.04 inches wide by 0.61 inch deep, it is relatively small as touch-screen phones go, though it is a bit thicker than average. Still, at 3.84 ounces it won't weigh you down. The 5800 also offers a sturdy, comfortable feel in the hand.The touch screen measures 3.2 inches, which makes it almost as big as the iPhone's. It supports 16 million colors (640x360 pixels) and has an aspect ration of 16:9. With that kind of resolution, colors are bright and vibrant and graphics and photos are sharp. You can change brightness, font size, and backlighting time. During a call, the 5800's display will go dark when you raise the phone to your ear. The brightness will adjust automatically to different lighting environments.
