Lumia - Computer Definition
A family of smartphones from Nokia that are based on Microsoft's Windows Phone platform. Introduced in 2011, the Lumia line is a vast departure from the look and feel of iPhones and Androids, both of which caused an explosion in smartphones in the 2007-2011 time frame. High-end Lumia models come with Nokia applications that offer free music streaming and turn-by-turn navigation. In addition, programs highlight restaurants, shops and events in the local area as well as offer suggestions for downloading new apps. See Windows Phone and PureView.
