Display settings
Use the Display settings to configure brightness and other screen settings.
Brightness  
Opens a dialog for adjusting the brightness of the screen. You can 
check Automatic brightness to set the phone to adjust the brightness 
automatically, using the phone’s built-in light sensor. Or uncheck that option to use the 
slider to set a brightness level you want at all times when using the phone. For the 
longest battery life between charges, use the dimmest comfortable brightness.
Auto-rotate screen  
Check to automatically switch the orientation of the screen 
as you turn the phone sideways or upright.
Animation  
Opens a dialog where you can set whether you want to enjoy animated 
transitions for some effects (such as opening menus), for all supported effects 
(including when navigating from screen to screen), or to enjoy a phone without any 
optional animation effects (this setting does not control animation in all applications).
Screen timeout  
Opens a dialog where you can set how long to wait after you 
touch the screen or press a button before the screen darkens. For the longest battery 
life between charges, use the shortest convenient timeout.
