Model Google nexus 4 + Creative WP-350 Why this is not default and I cant find an option for it baffles me. When I get a call and and my BT headset is connected but I want to use the phones built in speaker/mic how do i achieve this? That I have the option to switch after I have answered is not an acceptable solution. What idiot come up with the idea of sending the audio to the BT device when the users has the phone in its hand? Ayt thinking person would send the audio to the device the user are using.
