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.
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.The Nokia Lumia weighs 5.6 ounces and measures 5.0 x 2.7 x 0.45 inches. Its 1830mAh lithium-ion battery is rated at up to 7 hours of talk time, and up to 300 hours (12.5 days) of standby time.
At 5 inches tall by 2.7 inches wide by 0.45 inch deep, it’s a large phone. The smooth, matte finish helps it slide into pockets and purses, but because of the width and flat back, the Lumia 900 did feel a little flat in my hand. However, it was comfortable on the ear. It may feel a bit heavy at 5.6 ounces, but it’s also very solid. I’m a little worried about the long-term effect of finger grease and residue on the color, but in the short term, the finish survived my residual hand lotion and the direct application of a goo-gone solution without marring the color. source
