I got my droid razr m about a month ago. I have a plantonics discovery 975 Bluetooth headset. Up until 3 days ago it was working fine with my phone then all of a sudden it's not. It will pair, and connect...and when I place a call it makes the connected beeps but the call audio does not play through the headset. I've tried repairing, I've tried using a different headset altogether and still my phone will not play call audio through whatever headset is attached. It's very frustrating. I've looked online for help with this but I can't find any relevant posts. Anyone know how to fix this? I read somewhere that its possible there's a setting or app that's preventing my phone from transmitting through the Bluetooth but I haven't downloaded any new apps recently. Also, if this is the case how do I change it? Thanks in advance for any help!
