I have been through 4 S6 Edge's since May because I keep receiving a Bluetooth unexpectedly dropped error whenever connected to a car. I tried multiple cars, with the same result. I ran the gamut with T-Mobile tech support and Samsung support and none of their suggestions worked. I thought for sure that this was a Bluetooth issue with the phone because I had no problems being connected via Bluetooth to my LG G Watch, speakers or headphones. My husband has an S6 Edge as well and just got a new car with Bluetooth capability, he has had no problems and the only difference between the two of us is the smartwatch. I think there may be a communication error between the watch, phone and car trying to communicate at the same time. Does anyone else have Android Wear and a Galaxy S6 edge? Are you having the same problems? The watch and the phone work perfectly together. They stay connected 24-7 and would stay connected if I connected Bluetooth headphones or speakers on top of it. The problem happens when I try to connect to a car. It will work for about 2 minutes then drop Bluetooth to all devices, then connect again and go back and forth. HELP! I really want to be able to use the watch and be able to make calls in my car... Thank you!
