How to show the recent apps in the Overview button? On Android KitKat v4.4.2 that came with my phone the Overview button (the button that is not Home nor Back) is showing the home screen settings:

How can I change the button behavior to show the list of recent applications instead?
My old android 4.4 phone had me press and hold the home button, while that third button would pull up a menu. I believe that was how things worked in Android 4.4 days.
