Default ringtones are usually stored in /system/media/audio/ringtones
. You might be able to access this location using a file manager.
Keep in mind that, residing on /system
, this place is read-only at best without root-access: so while you should be able to copy from here, you cannot place any files into this directory. If you want to manually add ringtones to your device, rather create a similar directory on your SDcard (/sdcard/media/audio
, with sub-directories for ringtones
, alarms
, notifications
, etc.). This location should be recognized automatically by the Android system.
