The volume on BB Curve changes uncontrollably when I make or recieve calls - but does not when using the media player for music. The problem first occured when I was using the device to listen to music, closed the application to use the phone and then the volume change started.
I briefly got a message similar to "media malfuction" and then pulled the battery and was able to get the media player working again but note the volume during a call.
So let me see if I understand this correctly. You'll be on a phone call, and the volume changes all by itself? You're not accidently hitting the volume buttons?
