Have you found a solution for this yet? I've been searching for one since I got the edge 6 plus on at&t. It's apparently an at&t thing cause I have a Verizon note 5 for my work phone and it doesn't do it. I can't believe this isn't a thing people are complaining about. I have an Android wear watch and I can't answer another call on it while I'm on my BT headset without taking my phone out of my pocket to answer the "questionnaire" as I like to call it. Kinda defeats the purpose of a smart watch. I was hoping the marshmallow update would get rid of this but unfortunately not cause I just bought the S7 Edge and it does it too. Sorry for the rant and replying to an old post but this was the only mention of it on the internet as far as I could tell and I'm desperate!
