During the debut of Nokia's Lumia 920 and 820 Windows Phone 8 smartphones earlier this week, a demo of the phones' photo-editing functionality was proved false. The reason is because Nokia did not record footage from the phone; the company recently apologized.

Nokia described the move as "poor judgement." A spokesperson said the company is taking "appropriate action" following the embarrassment, though did not share details on what action it is taking.

The video (below) shows a girl riding on a bike alongside her partner, the latter filming her. The two ride past a trailer and a reflection shows a member of the camera crew filming with a DSLR camera with the riders, causing the embarrassment and this annotated video.

"In an effort to demonstrate the benefits of optical image stabilization (which eliminates blurry images and improves picture shots in low light conditions), we produced a video thats simulates what we will be able to deliver with OIS," Nokia admitted, adding it should have posted a disclaimer.

Nokia's Lumia 920 smartphone uses the PureView technology debuted in the Nokia PureView smartphone, with an eight-megapixel camera. The camera received early praise for the low-light photo-taking capability from critics. Nokia's track record is in design and camera technology.

The Lumia 920, in particular, is the successor to the Lumia 900. It features a 4.5-inch screen, multiple colours, and Windows Phone 8. It was confirmed the phone will arrive in November on UK network Everything Everywhere. U.S. customers have no news on when the phone will arrive. The move contrasted Apple; it revealed its iPhone 5 smartphone would be available for pre-order two weeks after the announcement for release next Friday. Apple sold out of iPhone 5s, halting pre-orders.

Microsoft is also yet to announced Windows Phone 8's launch date, though sources speaking to ZDNet claimed late October could be the launch date alongside Windows 8. The company is pushing app development hard; developers can co-build Windows 8 and Windows Phone 8 apps given the platforms almost identical user interfaces.

Windows Phone 8's launch is to be announced.
