I have a GS6 with Android 5.1.1. (kernal: 3.10.31-5028597) After I got the update, I cannot stay connected to my 2014 Toyota Highlander OEM bluetooth. It worked fine until the update. I have unpaired/repaired the bluetooth, I downloaded a 3rd party app (Bluetooth Auto Connect), I took the car to Toyota to make sure my head unit had the most up to date software. It does.
Nothing works. The car will still pair with the phone, but then drop the connection and will never reconnect.
My moms phone, a Verizon GS6 with 5.0.2 works fine.
Any way to revert to 5.0.2 or fix this problem? Your thoughts would be helpful.
