How does Vito set the SMS sound and ringtone?

Honey, I just bought D 10 today. I found your question at first, but I found the answer.

Find the music bar-select the music you want to set as ringtone and click Play-click the button in the lower left corner of the white screen during playing-and the ringtone will appear, and the one-click setting is successful.

Let's see if we can help the sisters of D 10.
