Changing the ringing volume when pressing volume keys The volume buttons of the HTC Wildfire S only changes the media volume, rather than ringing volume, even though I'm on the home screen.

Is there any way of changing the ringing volume when I click the volume buttons?
You probably played a game or something and didn't close it correctly. You probably just pressed the home screen. 

So, just restart it, or go back and close it properly.
