While Chang was booted for the looks of the Samsung Galaxy S5, the younger Lee received praise within the company for his work on designing the entire Galaxy range. Samsung has become the global leader in smartphone sales, thanks to strong shipments of the Galaxy line. The newly promoted Lee Min-hyouk has the nickname "Midas" inside Samsung, for his success with the Galaxy designs.
Still, Samsung has been criticized for the continued use of plastic on its high-end models. The Samsung Galaxy S5 also has to compete with the HTC One (M8), which has been considered one of the sharpest designed Android phones ever.
As for Chang, he will remain head of the company's design center, which decides the overall design strategy of Samsung.
