Add ringtones to your smartphone
You can add a file in any of the following file types as a ringtone for your smartphone: MP3, AAC, AAC+, AMR, QCELP, or WAV. How to use the file as a ringtone depends on the following: the file type, how you obtain the file, and whether you want to use the file as a ringtone only, or play it in the Music app.
You can obtain files to use as ringtones in any of the following ways:
•Download a ringtone from one of the many ringtone apps in App Catalog (see HP webOS App Catalog and Software Manager).
•Download an MP3 file that you want to use as a ringtone from the Amazon MP3 app (if available on your smartphone) (see Amazon MP3).
•Copy a file from your computer (see Copy a ringtone to your smartphone).
To use an AMR or QCELP file as a ringtone, the file must be stored in the ringtones folder in your smartphone’s USB drive storage. Here’s how to get the file into the correct folder:
•Files downloaded from App Catalog: The file is placed in the ringtones folder automatically.
•Files copied from your computer: You must place the file in the ringtones folder (see Copy a ringtone to your smartphone).
To use a file in the ringtones folder as a ringtone, see Select a file from the ringtones folder as a ringtone.
