The Nokia X is seen at its unveiling at the Mobile World Congress in Barcelona, February 24, 2014. Nokia, soon to be acquired by Microsoft Corp, is turning to software created by arch-rival Google for a new line of phones it hopes will make it a late contender in the dynamic low-cost smartphone market. Its first model, the Nokia X, will rely upon an open version of the Android mobile software system created by Google that has become the world’s most popular software used in smartphones.
