[Review] Nokia Lumia 900

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.

The Nokia Lumia weighs 5.6 ounces and measures 5.0 x 2.7 x 0.45 inches. Its 1830 mAh lithium-ion battery is rated at up to 7 hours of talk time, and up to 300 hours (12.5 days) of standby time. It runs on AT&T's UMTS Tri-band (850/1900/2100 MHz), GSM Quad-band (850/900/1800/1900 MHz), and LTE (700/AWS MHz).

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 720 p video capabilities and extra memory storage available via the SkyDrive cloud to ensure you can save all your files.

The Windows Phone 7.5 operating system has been designed to help you do more in fewer steps, and keep you updated on the things that are most important to you. Windows Phone 7.5 also brings together the things you use most on your phone in six Hubs: People, Pictures, Office, Games, Music + Video, and Marketplace. Grouping them in Hubs like this lets you get to what you need, quicker, because you don't have to jump from apps to the web to contact lists. You can customize the Live Tiles on your Start Screen with what you care about, from people to web sites, and they'll continuously scan the web to keep you updated about your world at a glance.

The latest release of Windows Phone, version 7.5, code-named "Mango", has hundreds of improvements and new features, including multitasking, improved live tiles, threads, send a text with your voice, local scout, driving directions, social network integration, persistent camera settings, history view, visual voice-mail, and sync with SkyDrive.
