Lee Min-hyouk, Samsung's vice president for mobile design, will take over Chang's position as head of the mobile design team, while Chang will continue to lead the design center at Samsung.
"The realignment will enable Chang to focus more on his role as head of the Design Strategy Team, the company's corporate design centre which is responsible for long-term design strategy across all of Samsung's businesses, including Mobile Communications," Samsung said in a statement.
Samsung's Galaxy-branded smartphones and tablets have been its flagship brand for several years now, helping it to overtake and surpass bitter mobile rival Apple globally in terms of smartphone sales.
