Conflicts w/ other Bluetooth connections?

Greetings!

Has anyone else noticed any conflicts with simultaneous bluetooth connections to other types of devices while the Gear S is paired to your phone?

I have a Note Edge from T-Mobile and the Gear S from T-Mo as well. In my car (Chevy Volt) I have the factory infotainment system with navigation, bluetooth, etc. I noticed that at seemingly random times, when I had the phone paired to the car and was either in a call or streaming music, the connection between the car and the phone would be lost. I chalked it up to an issue with the Bluetooth profile stack GM was using and used a wired connection.

Then, I experienced the exact same problem in my truck with an Aftermarket Pioneer head unit connected to the phone. It too would drop the connection at random intervals. That caused me to start to suspect the Note Edge or the ROM I was running on it.

Yesterday, I accidently left for work without my Gear S. Guess what? The connection didn't drop once during my 45 minute commute. So today, I turned off the Gear S before I left work work, and I never lost a connection.

This tells me there is some sort of an issue with the Gear S. Has anyone else experienced this? If so, have you found a fix? To the best of my knowledge, I am using the latest official firmware for the T-Mo Gear S, and I just updated the Gear S app for the phone through the Samsung store, etc.

Thanks!
