Media audio wired headphones does not stay checked

My galaxy s4 does not do the following: Using bluetooth and wired headphones plugged into aux in car. When a call comes in, it goes to the car speakers instead of the bluetooth. Your app does work, have to check the wried headphones and bluetooth mono. The problem is the bluetooth mono stays checked but the media audio wired headphones does not stay checked. So each time I have to check the media audio wired headphones. How can I make stay checked. I do have the pro version and that is where I am checking everything.

You may want to install the latest Beta version. You can find it here:

If you phone can detect headset being plugged in correctly, you should be able to automate.

1) "Media audio" setting to "Let app decide"
2) "Phone call audio" setting to "Let app decide"
3) Go into "Wired Headset behavior". Make sure "Wired headset detection" is checked.
4) Back
5) Go into "Bluetooth behavior". Make sure "Phone call usage" is checked.
