Roh, who came on board with Samsung in 1997, helped develop the Galaxy device lineup and is supposedly a stickler for engineering and design. He'll reportedly try to bolster Samsung's reputation for quality after it stumbled over the past few years. Under Koh, Samsung was forced to kill the flammable Galaxy Note 7 and had to delay the Galaxy Fold due to issues with the display.

Roh's primary goals will be to shepherd foldable products into the mainstream and help Samsung expand in China and India. Roh is also known as a cost-cutter who outsourced smartphone production to better compete with aggressive Chinese rivals like Huawei, Xiaomi and Oppo. He'll be getting to work right away, as Samsung should be unveiling its new Galaxy S20 flagship series and possibly a second-generation foldable device at a February 11th event in San Francisco.
