I have a Samsung Galaxy S4 and I have it paired to a bluetooth headphones(LG HBS-730) and my car (not at the same time). For awhile my controls worked on both but for the last 4 months, they have stopped working. The volume on the LG works but I can't pause playback. If someone is talking to me, I have to turn the headphones off. In the car, none of the controls work. I've recently upgraded to 4.4.2 but this problem was before the update.
Any help would be greatly appreciated.
