Intro (JK Shin) - Samsung Unpacked 2014 - Galaxy S5 Event - MWC - 006

Samsung’s mobile business has been struggling for a while now, and this week the company announced its biggest shakeup yet in an effort to turn its fortunes around. Mobile chief JK Shin will take a step back from day-to-day operations, though he’s holding onto his position as president and co-CEO or Samsung Electronics.

Shin’s replacement is Koh Dong Jin, who previously worked on mobile software projects for the company including Samsung Pay and its Knox security program. Koh also led development of the Galaxy S6 and Galaxy Note 5, and helped develop relationships with Google, Microsoft, Qualcomm and other firms.

The change in leadership suggests Samsung may put an even bigger focus on developing its own software in the future. It’s also the first time Samsung’s vice chairman Lee Jae Yong has asserted control over the company’s mobile business since taking over leadership from his father last year.

The transition should be a pretty smooth one, with Shin shifting his attention to “long-term” strategy. Koh’s clearly already had a hand in the last few flagship Galaxy phones, though it’s likely we’ll see the company put an even bigger emphasis on new apps that blend hardware and software, like Samsung Pay, moving forward.
