The Droid X Home Screens
Part of the Droid X For Dummies Cheat Sheet
The main screen on the Droid X is called the Home screen, but not everything you have loaded on your phone can be displayed in just one screen. There are actually seven Home screens to choose from on the Droid.
To quickly browse and preview the various Home screens, press and hold your finger on the dots in the lower left or right corners of the touchscreen. Then in the pop-up preview, touch a preview image to instantly open that part of the Home screen. Or, just touch anywhere else on the touchscreen to make the preview images go away.
