Four new smartphone OSes intend to challenge Apple and Google's dominant position. Mozilla's Firefox OS is the first out of the gate, but Canonical, Samsung Electronics and Intel, as well as Finnish upstart Jolla Mobile, are also getting their alternatives ready.
Phone makers and mobile operators are worried about the Android-iOS duopoly the smartphone market has evolved into. This concern has given birth to a new generation of OSes that its respective backers are hoping can make a mark.
Firefox in front
Of the four challengers, Firefox OS is the furthest along and is already in devices on the market.
The ZTE Open is the first Firefox OS phone to go on sale. It began shipping in Spain last month.
