Home and Android basics

 

: Tap quickly twice on a webpage, map, or other screen to zoom. For example, you double-tap a section of 

a webpage in Browser to zoom that section to fit the width of the screen. Double-tapping after pinching to zoom in 

some apps reflows a column of text to fit the width of the screen.

 

: In some apps (such as Maps, Browser, and Gallery), you can zoom in and out by placing two fingers on the 

screen at once and pinching them together (to zoom out) or spreading them apart (to zoom in).

 

: On most screens, the orientation of the screen rotates with the tablet as you turn it. You can turn 

this feature on and off, as described in “Screen settings” on page 96.

The System bar’s Navigation buttons make it easy to quickly switch among Android apps.
In some media apps, the System bar controls are replaced by dim dots when you’re watching a movie, slide show, and 

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.

Back

changes to a down arrow and touching it closes the keyboard.

Recent Apps
