I had a Samsung Galaxy S III and never had a problem. I got the Note 4 and my bluetooth would switch to the phone sound intermittently. The Bluetooth would then show bluetooth setup and phone. I could not click on phone, but I could click on bluetooth setup. I would touch the bluetooth setup and it would go to the next screen. The only option visible was bluetooth off. Nothing would happen if I touched it. Everything else is grayed out. This was an intermittent problem. Sometimes it would work fine, others not at all.
I brought the car in to Toyota and they took a look at the bluetooth and we were unable to get the bluetooth to come on. They said they reset the computer and the bluetooth was working. Again, it was working intermittently. Sometimes it works after shutting the car off and on. However, it shortly reverts back to the phone audio.
I brought the car back to Toyota and they replaced the radio and a bluetooth part. The bluetooth worked fine for 3 days. I got into the car and the bluetooth would not come on. I got to where I was going and when I started the car again, the bluetooth was working, but quickly cut back to the phone audio. I got to where I was going and when I restarted the car the bluetooth was working.
There is definitely something wrong with the car bluetooth and not my phone. The reason I believe this is due to if my phone did not work with the bluetooth, I should still be able to search for other bluetooth devices. The bluetooth in the car is off and does not allow me to add devices. So, even if I had another phone to connect, it would not find it. It is almost like I am in driving mode (even when parked) where I cannot do anything with the phone or bluetooth. The switching on its own to the phone has me completely baffled. Any advice would be helpful!

Again. Not the car. Note 4 chipset seems to ignore older bluetooth standards. I'm currently searching for a fix for my edge. I will call samsung later today.
