Samsung is changing around some of its executives. The head of its mobile design team Chang Dong-hoon is being replaced with VP of mobile design Lee Min-hyouk, according to Reuters. Chang Dong-hoon offered to resign after the launch of the Galaxy S5 had little fanfare compared to previous Samsung products. Samsung said Dong-hoon will be focusing on the company’s corporate design center, which manages Samsung’s design strategy company-wide. Min-hyouk has been overseeing the design of the Samsung Galaxy S series since it launched.
