After months of speculation, Amazon has unveiled its first smartphone: the Fire Phone. Its US release date is 25 July.
The device has a 4.7in screen, a 13-megapixel rear camera, and an innovative system of cameras and sensors on the front of the phone to track head gestures from users, and change the display accordingly.
The Fire Phone also has a feature called Firefly that identifies songs, films, TV shows, books and products, then directs people to buy them from Amazon. It will also identify signs, artworks and wine labels, and provide more information on them.
People paying $199 for the Fire Phone on a two-year contract from US mobile operator AT&T will also get a year's free subscription to the Amazon Prime subscription service.
