Compal Electronics has already undertaken ODM production of Windows Phone 8 (WP8) smartphones for Nokia, and fellow makers Quanta Computer, Wistron and Pegatron are poised to compete for WP8 orders, according to supply chain makers.

　　Microsoft has offered free licensing to boost WP8, and consequently some China- and India-based smartphone vendors have adopted the operating system, the sources indicated. In particular, China-based Huawei Device, ZTE, Lenovo, GiONEE and K-Touch plan to launch entry-level and mid-range Windows Phone 8.1 smartphones in the China and other emerging markets, the sources said.

　　China-based BYD and Longcheer Holdings will also compete for Windows Phone 8 smartphone ODM orders, the sources indicated.
