Revamp at Lenovo mobile

Company says change of management will not affect sales, profit goals for troubled unit

The head of Lenovo Group Ltd's mobile business has stepped down amid the personal computer giant's continued struggles to stay ahead of rivals like Xiaomi Corp and Huawei Technologies Co Ltd.

Liu Jun, head of Lenovo's mobile business group and chairman of the newly acquired subsidiary Motorola Mobility, will serve as a special consultant to Chief Executive Yang Yuanqing on mobile strategy "for a certain period of time" before leaving the company, Lenovo said Tuesday in a statement.
