We have already told you about Windows Phone Mango OS based Nokia smartphones Nokia Lumia 800 and Nokia Lumia 710 few days ago, Now Nokia expanded its Lumia Series portfolio with addition of Nokia Lumia 900 smartphone ( a.k.a. Nokia ACE), which is exclusively launched on AT&T carrier for the time being to mark a strong comeback in US market and to take head to head competition with Apple iPhone 4S and Samsung Galaxy S2. It is Nokia’s first 4G LTE enabled device for AT&T. Lumia 900 may be launched in other countries after some time, although there is no official statement from Nokia about it but according to sources there may be difference in specs, means may be no LTE support in Europe version but price may be cheaper. Nokia Lumia 900 price for AT&T is still to be announced so we will first check the Nokia Lumia 900 Specifications and Features.

Lumia 900 borrowed its basic looks from Nokia N9 or Lumia 800, although it has bigger in size and have some additional features to its kitty. The phone dimension measures 127.8 x 68.5 x 11.5 mm with 160 gm of weight and it is made by polycarbonate body as seen in N9 or 800. The phone is based on Windows Phone 7.5 Mango operating system similar to Lumia 800 but it has additionally 4G LTE capability features in it. Nokia Lumia 900 features a 4.3 inch AMOLED capacitive touchscreen display with 16M colors supported by Nokia ClearBlack display and Corning Gorilla Glass technology to handle scratches. The multitouch display offers standard Windows Phone Mango screen resolution of 480 x 800 pixels and 217 ppi pixel density.

Nokia Lumia 900 camera has 8 megapixels camera resolution with Carl Zeiss optics, autofocus and dual-LED flash to enhance your image capturing experience. It is also able in 720p HD video recording @ 30 fps and video stablization to capture friends and family videos. It also has 1.3 megapixel front facing camera with VGA recording @ 30 fps for video calling, the feature we miss in Lumia 800.

Nokia Lumia 900 Specifications includes Qualcomm APQ8055 Snapdragon Chipset, 1.4 GHz Scorpion CPU, Adreno 205 GPU with Accelerometer, gyro, proximity and compass Sensors. It has 512 MB RAM and 16 GB total internal memory, out of which 14.5 GB memory is used for user purpose, you can also use 25 GB memory on SkyDrive cloud storage comes with the package. Although you can miss memory card slot here, There is no support for micro-SD memory card slot in WP7 OS. The phone only works with Micro SIM card so you have to cut your card to fit in the slot or replace new SIM from your operator.

Nokia Lumia 900 features and specs also include  4G LTE Cat 3 (50 Mbps Downlink, 25 Mbps Uplink), Bing, Internet Explorer 9, HTML5, Wi-Fi 802.11b/g/n, Bluetooth 2.1 +EDR, USB 2.0 High-Speed, 3.5mm AHJ Connector, Bluetooth Stereo Audio, Micro USB, Proximity sensor, Magnetometer Sensor, Ambient light sensor, Gyroscope sensor, A-GPS, Bing Maps, AT&T Navigator, Tango Video Calls, Nokia Maps (available as a free download), Nokia Drive (available as a free download), Xbox Live, Marketplace, App Highlights, ESPN Sports Hub, AT&T U-verse Mobile, Use as a WiFi Hotspot for up to 5 WiFi-enabled devices and Hardware Graphics Acceleration. The phone comes with BP-6EW 1830mAh battery capable of  7 hours Maximum 2G talk time and 3G talk time, 300 hours Maximum GSM and 3G standby time.

But the phone does not have DivX/XviD support or many audio file support, no USB mass storage support and no support for Bluetooth file sharing. You have to use Zune desktop software for that, which is main disadvantage of Windows Mango OS.
