Microsoft plans to roll out its Windows Phone “Tango” update for its mobile platform in China some time this year. While the new version of Microsoft’s OS will allow Windows Phones to hit lower price points, Chinese manufacturers are pessimistic about the plan and believe the operating system may not achieve enough success, according to DigiTimes. Android-based smartphones are believed to continue to dominate the Chinese market due to the aggressive marketing of low-end devices from local vendors such as ZTE, Huawei, Coolpad and Xiaomi Technology, and the ease of developing applications through the open-source operating system. Despite unfavorable market conditions, Nokia will lead the charge into China with devices set to launch in the first half of 2012. The publication’s sources also believe Huawei will release several Windows Phones din the second quarter, with Microsoft also looking to partner with Lenovo and ZTE to launch devices in the Chinese market.
