Samsung's Dennis Miloseski backstage at Expand video

We had a chance to grill the head of Samsung's North American design studio, Dennis Miloseski, during our panel discussion about the growing sophistication of mobile devices here at Expand. As it turns out, he had even more to talk about, so we wired him up and threw him in the hot seat backstage. He gave us a look into the story behind the Galaxy S 4, the changing face of TouchWiz UI and building Samsung's design studio stateside. For the full interview, check out the video after the break.
