The Nokia Lumia 900 4G LTE phone features a large and vibrant 4.3-inch AMOLED ClearBlack Display. The AMOLED (active-matrix organic light-emitting diode) technology increases the refresh rate of the screen and enhances the contrast ratio while reducing energy consumption to increase battery life. The ClearBlack Display (CBD) feature blocks incoming light reflections through a polarized layer to improve screen visibility under direct sunlight. This smartphone does not shy away from technology to enrich the user experience.
Note: AT&T's 4G mobile broadband coverage is not available in all areas. 4G speeds delivered by HSPA+ with enhanced backhaul; availability increasing with ongoing backhaul deployment.
In addition to the beautiful display features, the Lumia 900 utilizes its 1.4 GHz Qualcomm single-core processor to run the Windows 7.5 operating system, which has been designed to keep phone tasks simple and easy for the everyday user. If you are an avid photographer, you will be happy to know the 8 megapixel camera features Carl Zeiss optics, auto-focus, and a dual LED flash to enhance dim lighting situations. In addition to the still camera, the Lumia has 720p video capabilities and extra memory storage available via the SkyDrive cloud to ensure you can save all your files.
With AT&T's 4G HSPA+ network, you'll enjoy mobile broadband speeds up to 4x faster than AT&T's already fast mobile broadband network (learn more below). You also get the AT&T Mobile Hotspot service built right into the smartphone--enabling you to connect additional Wi-Fi-enabled devices to the phone's mobile broadband signal (requires appropriate data plan). This GPS-enabled phone can also access the AT&T Navigator service for turn-by-turn directions.
