At the London Olympics, Jung, together with Lee, won the men's doubles bronze medal. The pair who were seeded two, advanced to the knock-out stage after placing first, won three matches in group D stage. They lost the match in the semi-final match against Mathias Boe and Carsten Mogensen of Denmark, and in the bronze medal match, they beat the Malaysian pair Koo Kien Keat and Tan Boon Heong in straight games. That was Jung's final tournament.
