Android Mobile Phone has Three Buttons instead of only One Home Button for Productivity

At the bottom part of an Android mobile phone, you can see that there are three buttons. The three buttons are the Back button, the Home button and the Recent Apps button as shown below.

+--------+--------+---------+

|  Back  |  Home  | Recent  |

|        |        | Apps    |

+--------+--------+---------+

With three buttons instead of only one middle Home button, you have more customizable actions to play with.

The Back button should be at the leftmost just like the back button on the web browser toolbar. The Home button will take you to the home screen by tapping one time on it. The Recent Apps button at the bottom rightmost of the mobile phone displays the most recently opened apps.
