I'm having an issue with my bluetooth holding a connection with my 2013 Honda Civic LX. When listening to music through any music playing app, the connection always stays steady. When there is no music running from the phone, I'll frequently get a message from the display on the dash that the phone has been disconnected. The phone will usually reconnect in a second or two, with another display indicating that it has been connected. This will happen at least two times during my commute to work (25 minutes), oftentimes as many as five times. When I am actively in a phone call, the disconnects seem to be more frequent. It has a timer on the display that shows how long the phone call has been active through the car, and it rarely gets above 3 minutes before the call gets routed back to the phone's speakers while the bluetooth reconnects. The strange thing is that my wife's LG G4, also AT&T, has absolutely no connection issues at any time. I switched phones with her for a week just to confirm since I'm the one generally driving this car, and I didn't have the car drop the connection to the phone even once. Before that week, her phone would have occasionally been used when we were both in the car and she wanted to listen to music through her phone, so it had been connected to the car for more than a week.
I factory reset the phone just to see if there was a strange software issue causing the problem. After the factory reset, the phone and car had a steady connection with no drops for about a week. When the problem came back and was obviously just as bad as before, I tried another factory reset. Once again, the connection stayed steady for about a week before I would get disconnects again. At this point, I contacted AT&T, who replaced my phone thinking that it could be a hardware issue. A week after getting my replacement, the issue popped up once again.
Besides factory resetting, which is the only thing I've found to fix it at least temporarily, I have tried a few different troubleshooting steps. I have cleared cache using the storage screen in the settings menu. I've deleted the phone from the car's connection list. I've re-paired the phone to the car without giving permission for contacts or messages. Also tried to just do a simple reboot of the phone, as well as turning bluetooth off and back on. None of these have any effect on the connection issues once they start coming up.
I can take the car to Honda, but judging on the fact that my wife's phone works just fine in the car, I'm convinced that it is somehow an issue with the software on my phone. My phone is not rooted, and is currently running Android 5.1, S/W H81010o, Build LMY47D.
