How the Nokia Lumia 900 Will Work

Lumia 900 Hardware and Specs

The Lumia 900 display is big -- much bigger than the screens on the Lumia 800 and Lumia 710. The 900 follows in the tracks of Android phone development, trending away from the 3.7-inch (9.4 centimeter) screen of the iPhone into 4.3-inch (10.9-centimeter) territory. The Lumia 900 displays Windows Phone 7 on an AMOLED touch screen at a resolution of 800 by 480 pixels. That's a standard resolution for Windows Phone 7 and common on the Android platform as well. In fact, a 4.3-inch (10.9-centimeter), 800 by 480 display is just one of many hardware guidelines Microsoft set out for Windows Phone 7 to ensure consistency across the brand.

The platform's initial requirements included a 1 GHz processor, touchscreen, specific buttons below the phone display, and sensors like an accelerometer, gyroscope and magnetometer [source: CNET]. The Lumia 900 matches those requirements with a 1.4 GHz single-core processor, the expected array of sensors and 512MB of RAM.

Nokia is well-known for offering some of the best cameras in the phone space, and the Lumia 900 uses an eight megapixel sensor, dual-LED flash and Carl Zeiss lens to shoot photos or 720p video. A 1MP camera sits on the front of the phone for video calls. Nokia's affinity for cameras gels with the Windows Phone 7 because Microsoft prioritized speedy camera access in its operating system. All Windows Phone 7 devices include hardware shutter buttons for instantly launching the camera app and snapping pictures.
