Add ZTE (0763) to the list of manufacturers trying to decrease their dependence on Android by diversifying their mobile portfolios. The company’s executive vice president He Shiyou told The Wall Street Journal on Wednesday that ZTE will launch smartphones with Mozilla’s Firefox OS in the first quarter of 2013, while also confirming that ZTE is planning new Windows Phone 8 smartphones to go on sale later this year. Mozilla revealed plans for its own HTML5-based mobile platform earlier this year and said that initial hardware partners will include ZTE, TCL and Qualcomm (QCOM).
