Motorola says searching for new cell phone head

NEW YORK, March 3 (Reuters) - Motorola Inc (MOT.N) is searching for a full-time leader for its mobile devices unit, the company's Chief Executive Officer Greg Brown said on Monday.

Brown took over from Stu Reed as head of the loss-making unit around the start of last month on top of his job as CEO.

Motorola, the world's third biggest mobile phone maker, has been losing market share to rivals such as Nokia Oyj (NOK1V.HE) and Samsung Electronics (005930.KS).

Brown said that the unit could eventually get back to profit margins in the double-digit percentage range but did not give a timeframe during the Webcast of an analyst conference.

"Longer term there's no structural impediments to driving double-digit margins in handsets," said Brown, adding that he spends about 80 percent of his time working on the mobile unit, Motorola's biggest division. (Reporting by Sinead Carew, editing by Phil Berlowitz)
