So I understand that 8.1 had several fixes for bluetooth, however I'm still experiencing some issues. I am not sure if it is an iPhone issue or iOS issue (I've tested on 2 iPhone 6's). I use the bluetooth connection that came stock on my Mitsubishi, and have used it with the past 3 iPhones. Currently the behavior is when connected via Bluetooth, if I initiate a call on the handset, it will not switch to bluetooth automatically once the call is answered, I have to manually change the source. I have checked for every possible setting to make sure all features were set correctly, and it appears to simply be a bug. I'm also noticing some issues with bluetooth disconnecting and reconnecting during a call. Is anyone else experiencing the same behavior?
