One of the most popular things to do with any phone is customization. This is usually accomplished through wallpapers and sounds on “dumb phones” and through themes, skins, widgets, and custom shell applications (home screens) on smart phones.
System Sounds and Ringtones
Android can play any MP3 or OGG audio file as a ringtone. Android has several types of system sounds: alarms, notifications, ringtones, and ui.
The easiest way to change your system sounds is to place the audio on your SD card in a new folder called “audio” with subfolders for “alarms”, “notifications”, “ringtones”, and “ui”. Place whatever audio file you want into its appropriate folder, then reboot the phone for the system to “see” your new files, then customize as you like.
Changing the default sounds is easily configurable in the system settings. From your home screen, press the menu button, tap “settings”, then “sound & display”. From this page you can set your “Phone ringtone”, and “Notification ringtone”. (If you don’t see the files that you added, restart your phone.)
Now you can download virtually any MP3 or OGG file and use it to notify you of an incoming call, tweet, Facebook update, or even to wake you up in the morning.
