Several manufacturers, including Samsung, LG and Kyocera had made attempts to create a dual-screen smartphone. However, they proved unsuccessful as their second screens were located within a difficult to access clam-shell design. +more The Siam 7x overcame this by placing the second screen on the outside, using a black and white E Ink Corporation screen to conserve power. A similar design was created by Yotaphone but its parent company targeted this phone to European, Asian and Middle-Eastern markets. The Siam 7x was the first dual-screen phone designed for the North American market.
The phone was available only with the Android operating system, and only as a GSM carrier phone. It allows users to insert two SIM cards simultaneously. +more The phone was designed in Dallas, and manufactured in Shenzhen, China.
Furthermore the phone has a bio-metric ear print recognition system which employs the Descartes Bio-metric Helix system
The Siam 7x dual-screen smartphone was released to the public on November 27, 2015 (Black Friday). 10,000 of these phones were produced for its release date, targeting a relatively small sales volume.
