Solution to disabled Bluetooth Call Audio

Apr 5, 2017



If you're on Android 7.0 Nougat and your car hand-free mode stopped working, just check this out...





This happened to me recently and I suspect the recent re-introduction of Google Maps real-time location sharing to be related: my phone would no longer transfer the phone calls to the car hand-free unit.

It turns out that the "Call Audio" option for that Bluetooth device became disabled and could not be re-enabled by any mean.

The culprit is an option called "Bluetooth scanning", which, since Nougat, has been relocated in the upper right menu under Settings > Location




















Once there, just disable the "Bluetooth scanning" option.



















Now, go back to the Bluetooth settings and enable "Call audio".
This time the option will remain enabled.
