Nokia has unveiled the Lumia 920,its new flagship smartphone based on Microsoft's upcoming Windows Phone 8 mobile operating system.
The Finnish company chose New York for the launch,which served as both a smartphone unveiling and a chance for Microsoft to show off its new software to a wide audience.
The Lumia 920 looks very similar to previous high-end devices running a Windows Phone OS,but has a number of additional features designed to win users over from Android and iPhone handsets.
It has a 4.5in curved glass display with PureMotion HD+technology,giving it a fast refresh rate,and a clear black display to automatically adjust to sunlight and remove glare.
It runs on a Qualcomm Snapdragon S4 chip,which Nokia claimed gives 30%more battery efficiency,and offers wireless charging.Nokia has signed deals with Virgin Atlantic and Coffee Bean to provide charging pads within their lounges and stores,and hopes more retailers will get involved.
There have also been improvements to the camera,using Nokia's Pureview developments to control lighting and offer floating lens technology for smoother capture of video.
But despite calling the Lumia 920 the flagship device for Microsoft's mobile OS,Samsung has already unveiled a Windows Phone 8 device and HTC's launch is due shortly,so Nokia is still set to face competition.
The launch date and pricing for the UK has not been confirmed,but Nokia said the handsets should arrive in select markets later this year.
