Hello
I am using a BlackBerry 9700 with OS 6 installed.
When I am on a long walk the output method sometimes switches on me. I will be walking and listening to PT on my Bluetooth headset and for no reason the sound will start coming from the BlackBerry speaker phone. If I choose the option for "Select Output" has changed to "Handsfree". I then change it back to "Stereo Bluetooth" and it works again for awhile and switches once again.
I should state this is not a huge deal and only seems to happen when I am outside which leads me to believe that for some reason the Bluetooth connection is being lost for a brief moment forcing the change.
