My Samsung SCH-U640 Convoy is not capable to not connect to Supertooth Disco speakers by the use of Bluetooth. No matter how I try to connect the device it just fails to accomplish. The device information (on top of cell phone) shows "Unsupported Device" up till now. As far as I know that the SCH-U640 does support A2DP profile which is necessary for the Supertooth. Does anybody have SCH-U640 working through the Supertooth Disco by the use of Bluetooth?
