Nokia's Lumia 920 may not be as disappointing as some critics said it would be. Actually, the Windows 8 smartphone is flying off shelves as we speak, which is a good sign for Nokia's Black Friday sales.

The Lumia 920 has already made it on the Amazon Best Sellers list. It is already in high demand in Germany.

According to AllThingsD, a number of Nokia Deutschland's German retail partners experienced "stock-outs" since the device first became available earlier November.

"Because of the high demand, we are aware of the reports the Lumia 920 is sold out in many shops," Nokia explained. "Please be assured that we are working hard on having all models and all colors available in Germany for you."

Nokia shares have gone up as well. AllThingsD reported that the shares closed up more than 6 percent Monday, "the biggest gain they've seen in weeks."

A review by Chron.com said that the Lumia 920 has an "excellent" 8.7megapixel camera with Carl Zeiss lens and a smooth finish despite thesmartphone being heavy in the hands, weighing 6.52 ounces, and not having a lot of memory.

Price may have something to do with the strong demand.

The Lumia 920 is $99.99 with a two-year AT&T contract, which is cheaper than the popular Apple iPhone 5 and some Android smartphones.

According to Pop Herald, Amazon Wireless now offers the Lumia 920 for $69.99 with a two-year contract with AT&T. With every order, consumers get a free wireless charger with every order.

Seventy dollars is not as cheap as waiting for Black Friday though.

The popular Windows 8 phone will be just $49.99 through AT&T on Friday, Nov 23, through Sunday, Nov. 25, reported Ubergizmo. A very affordable price will bring some new awaiting customers ready to try out Microsoft's new smartphone software.

The Lumia 920 runs on Microsoft Windows Phone 8. It takes many of the physical design elements from previous generations of Lumia handsets, but improves on internal hardware and display technology. Some of the new tech specs include PureMotion HD+ 4.5 inch display (1280 x 768 resolution), Dual-core 1.5GHz Snapdragon S4 processor, NFC chip with 332ppi and Corning Gorilla Glass 2, 2,000mAh battery, and Qi wireless charging. It has an 8.7 megapixel PureView camera with Carl Zeiss lens. It has rounded edges and comes in colors black, cyan, red, white, and yellow.
