Assuming you would like to know how to export ringtones from your Android device to a computer, there are a few things you need:
-A USB cable that is compatible with your Android device
-A computer with internet access
-An account on a file sharing website (optional)
First, connect your Android device to the computer using the USB cable. Next, open up My Computer (for Windows users) or Finder (for Mac users). Find the icon for your phone and double click it. Once inside your phone's storage, look for the folder named Ringtones or something similar. If you can't find it, try searching for .mp3 files. Copy the files in this folder onto your computer.
You can now either keep these files on your computer or upload them to a file sharing website so that others can download them as well. That's all there is to it!
