Back to the future as Samsung releases flip smartphone Samsung is targeting the phone at the Chinese market and there are currently no plans to release the device in Europe or the US. However, an unlocked version could potentially work abroad as dual-SIM support is included for both CDMA and GSM radios. The company said the phone was aimed at those who wanted to move on from "the old school" in a statement on their Chinese website. Users can send and receive messages and browse the internet without opening the screen of their device, the South Korean company said. It also contains a function to let users switch easily between "work" and "home-life" settings. Samsung was the number one mobile phone handset-producer in the world over the second quarter of 2013 according to estimates by research company Gartner, with more than 107m units sold. This put it ahead of Nokia, with 60.9m units, and Apple, with 31.8m.
