Nokia unofficially/officially confirmed its new Lumia 928 top-of-the-line smartphone, adding more teasers with a new video of the upcoming Windows Phone handset.

The Nokia Lumia 928 sparked lots of rumors and speculation, and Nokia is teasing it hard to create some hype for the upcoming Windows 8 flagship.

On Tuesday, May 7, Engadget posted an image of an ad for the Nokia Lumia 928 in the latest Vanity Fair magazine. The ad features a smartphone in someone's hand, as the user captures a photo or video of some good-old family fun at the beach. Just above the screen, the handset sports both Verizon and Nokia logos, which can only mean the smartphone is heading to the Big Red.

The Finnish company now decided to ramp up the excitement and tout the Nokia Lumia 928 a little bit more, posting a new camera comparison video on its U.S. website. While the Vanity Fair ad promotes Nokia's PureView camera technology, the Carl Zeiss camera optics and its ability to capture photos "even in low light," the new video adds more teasing.

The camera comparison video pits the upcoming Nokia Lumia 928 Windows Phone flagship against two of the most hyped handsets in the smartphone market: the Samsung Galaxy S3 and the iPhone 5. The next-generation Lumia device may not be mentioned specifically by name in the actual text or video, but the page's URL leaves little room for interpretation: https://www.nokia.com/us-en/lumia928.

The company's U.S. website further confirms the smartphone will boast an 8.7-megapixel PureView camera with Carl Zeiss optics and the great optical image stabilization first seen on the Nokia Lumia 920. In fact, the camera specs of the Lumia 928 are exactly the same as on the Lumia 920. The design, meanwhile, sports a few changes, including what seems like blunted sides rather than the rounded edges found on the Lumia 920.

According to the video touting Nokia's low-light camera performance, tests showed that the Lumia has greater color saturation and sharper image focus compared to the iPhone 5, and less video noise and sharper image focus compared to the Samsung Galaxy S3.

On the other hand, one intriguing aspect that's impossible to ignore is that Nokia decided to pit its upcoming smartphone against Samsung's last-generation flagship, not the latest Samsung Galaxy S4 which has a 13-megapixel camera. With that said, check out the video to see for yourself.
