The problem is there is a recording feature that was in 4.3 Jelly Bean however it was left out of KitKat 4.4.2. I have a Samsung Galaxy Note 3. I found that if I change my Audio Source as Camcorder - file format .mp3 and the highest KHz and you have to answer and take the call on speaker phone. Then it works!!! Just a workaround for now. Hopefully this will get fix. I been talking to Google. I was supposed to receive a link to make recommendations. I will call back and get it. Then I will post it here and if enough people ask for it maybe the will make the change. Also, I think updates should be optional.
