And that's not dedicated, so you have to launch the app any time you want to take a picture, so you miss photo opportunities doing that. Dedicated is like Windows Phone where pressing the button takes a picture, regardless of the app you're in.
I guess he misspoke. Regardless of which app you're in or even if the screen is switched off, pressing the camera button for a couple of seconds opens the camera app. Whether you take a picture or video is up to you. It's much faster than fiddling around for the power button and then tap the camera button on screen.
