Nokia Lumia 800

The Nokia Lumia 800, which was codenamed 'Sea Ray', is a smartphone that was launched by Nokia on October 26, 2011, at the Nokia World 2011 event.^[8] Initially, it operated on Snapdragon S2 processor and Windows Phone 7.5 "Mango" and was the first device manufactured by Nokia to run on the Windows Phone operating system. This marked a significant shift for the company from using Symbian for their smartphones. Upon its original release in November 2011 in Europe, it was Nokia's flagship product and was hence a crucial product for their mobile phone business.^[9][10][11]

Lumia 800 shares its design with the previously released MeeGo-based Nokia N9 and it was originally Meego CDMA-variant for Verizon with codename RM-716 Searay.^[12] The outward differences are one added physical button dedicated to the camera on the right side of the phone, and a dual LED flash moved directly above the Carl Zeiss camera lens.^[13] Despite a similar exterior, the Lumia 800 has a different interior than N9. Lumia 800's chipset comes from Qualcomm S2 processor, whereas the N9 is based on a Texas Instruments OMAP chipset and CPU.^[14] Like the N9, it has a convex-curved Gorilla Glass AMOLED PenTile screen with a ClearBlack antiglare filter. The screen diagonal is 3.7 inches (800 x 480 pixels), compared with 3.9 inches (854 x 480 pixels) for N9, to conform with the Windows Phone specifications list, which includes three capacitive softkeys placed under the glass. A through-colored unibody shell is made from polycarbonate plastic.^[1]

It was replaced as the flagship by Nokia Lumia 900, which was originally released for the American market through AT&T before its worldwide release.^[15] On 5 September 2012, the Nokia Lumia 820, the successor of the Nokia Lumia 800, was presented. The improvements are Windows Phone 8, dual core processor, front camera, wireless charging option, exchangeable covers, and bigger screen.^[3]
