Using the Navigation buttons
The System bar's Navigation buttons make it easy to quickly switch among Android apps.

so on, so you can better enjoy them without the distraction of the System bar. You can touch a dot as it if were the
control it stands for, or touch a blank area of the System bar to restore it to full view.
