About Wolyoom
When you're on the home screen and you push the volume buttons on your phone, it opens the RINGER Volume Dialog Box. If, for some reason, you want to change your mobile's media volume before, say, playing a song or a video, you need to either open the song AND THEN press the volume buttons, OR go digging inside the settings to find the media volume control.
INSTEAD, just open this little pucker which will bring up the Media Volume controls. Just set the volume, and go about your business.
