Physical and virtual buttons differ in what they do.
The virtual on screen buttons relate to "recent apps", "home" and "back"
When you switch to "physical" buttons, "home" and "back" remain, but the recent apps button turns into the "extended settings"/"menu" button. Go ahead, try that button in an app, it'll open some settings menu.
The recent apps button is moved to a long press of the home button. |
