However, they proved unsuccessful, as their second screens were located within a difficult-to -access clam-shell design The Siam 7x, however, placed 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.[3] The phone was available only with the Android operating system, and only as a GSM carrier phone/ . It also allows a user to insert two SIM cards simultaneously. The phone was designed in Dallas, and manufactured in Shenzhen, China. [4] HardwareThe Siam 7x operates on Android 5.1. The screen on the front is a5.0" 1280x720 HD IPS 2.5D display, multi-touch while the screen on the reverse side is a 4.7" QHD E-ink paper 2.5D display, multi-touch. It runs on a MTK6735A, Quad-Core，Cortex A53 CPU and utilizes an ARM MaliT760-MP3@450 MHz GPU. It has a hard-drive size of 16 GB with 2 GB of RAM. The amount of hard-drive space can be expanded to 64 GB with a TF Card. It has a biometric earprint recognition system which employs the Descartes Biometrix Helix system.[5] ReceptionThe 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.[6] References1. ^{{cite web |url=https://www.siamsmartphone.com/black-siam-7x-dual-screen-smart-phone.html|title=SIAM 7X Dual Screen Mobile |date=1 December 2015 |publisher=CRBT Siam |accessdate=2016-05-02}} 2. ^{{cite web|url=http://www.cnet.com/news/hands-on-with-the-siam-7x-dual-screen-smartphone/ |title=Hands-on with the Siam 7x Dual-Screen Smartphone |publisher=CNET|date=2016-03-16 |first=Rick |last=Broida |accessdate=2016-05-02}} 3. ^{{cite web|url=http://www.blackenterprise.com/technology/black-ceo-and-founder-creates-the-siam-7x-dual-screen-phone/|title=Black CEO and Founder Creates the Siam 7X Dual Screen Phone |publisher=Black Enterprise |date=2016-04-19 |first=Samara |last=Lynn |accessdate=2016-05-02}} 4. ^{{cite web|url=http://www.huffingtonpost.com/billrobinson/the-siam-7x-dualscreen-sm_b_8570046.html |title=The Siam 7X Dual-Screen Smartphone: One Lonely Entrepreneur's Chase to Build it |publisher=Huffington Post |date=2015-12-15 |first=Bill |last=Robinson |accessdate=2016-05-01}} 5. ^{{cite web|url=http://www.pocket-lint.com/news/135762-siam-7x-offers-dual-screens-and-earprint-biometric-recogintion|title=Siam 7x Offers Dual-screens and Earprint Biometric Recognition |publisher=Pocket-link |date=2015-11-03 |first=Luke |last=Edwards |accessdate=2016-05-02}} 6. ^{{cite web|url=https://www.pcmag.com/news/343531/the-siam-7x-americas-yotaphone-may-have-a-chance|title=The Siam 7x, America's Yotaphone, May Have a Chance |publisher=PC Mag |date=2016-04-07 |first=Sascha |last=Segan |accessdate=2016-05-02}} 7. ^[https://www.siamsmartphone.com/dual-screen-phone-duo.html Dual screen phone Duo].
