Microsoft’s general manager of Windows Phone, Gavin Kim, has left the firm. Kim joined Microsoft five months ago after working as an executive with Samsung where he was highly involved in the launch of the Galaxy S II and the company’s first tablets, including the Galaxy Tab 10.1. “We can confirm that Gavin Kim has made a personal decision to leave Microsoft,” a Microsoft spokesperson said in a statement to ZDNET. “We feel very good about the work he has done to set the team, and its new lead Eugene Ho, up for success. We wish him all the best.” It’s unclear where Kim will head next and he was not immediately available for comment but, we too, wish him the best.
