Hi. I just wanted to know how we can send mp3 files through WhatsApp. I know there's no direct way to send it but i read that you can change the file's extension to '.mp4' and then copy the file to ' pictures' folder and then you could attach it as video from WhatsApp. It will be received as a mp3 file on the other hand. But I'm unable to do this. Do you guys know any other way?
