Nokia has apologised for a video demonstration that led viewers to believe it had been filmed with its new smartphone but was in fact made with other equipment.
"We apologise for the confusion we created," Nokia wrote in a blog post entitled An Apology is Due.
In the video clip screened on Wednesday at a media conference for the launch of Nokia's new flagship Lumia 920 smartphone, a reflection in a window reveals that the video was not shot using a mobile phone but another type of camera.
