Hello, I am using a Motorola Razr MAXX with MIUI 2.12.28. I connected the Jabra Clipper Stereo Bluetooth headset, the sound was fine when playing music,movies. But if i tried to make any calls with the headset there would be lots of disturbance. Couldn't hear the person on the other end and vice versa. I connected the headset to a laptop and did a skype call there was no disturbance. I went back to original ICS ROM no disturbance on calls. So I am guessing some problem or some settings needed for it to work properly while making calls on MIUI. Thank You.
