Amazon has released details of its new smartphone Fire which it hopes can eat up market share from rivals Samsung, Apple and Nokia.

Users can now auto- scroll through menus and can read a long web page or book without having to touch the screen.

Jeff Bezos, Amazon‘s CEO said: “The Firefly button lets you identify printed web and email addresses, phone numbers, QR and bar codes, artwork, and over 100 million items, including songs, movies, TV shows, and products.”

Tech magazine Wired said: “Bulking up the Amazon Appstore is a big reason why this phone exists; even though its out-of-box features look incredible, its success may hinge on the creativity of third-party developers.

“Amazon is certainly hoping that the unique opportunities presented by its new hardware will inspire developers.”

A 32GB will retail for $199 with a two-year contract while a 64GB version will cost $299 for the same contract length.
