I have a Moto X play which I use regularly with a hands free bluetooth device in my lorry. This will work fine for a while, but then someone will call, the hands free makes its noise but on pressing answer I can hear nothing and neither can the caller. Occasionally I can hear the caller but they cannot hear me. I have to switch off the phone and reboot and it works fine again for a brief while before the same issues arise. I have read up that you have to allow BCap/MMAp or something like that, however this option is not available when deleting the bluetooth and setting it up from scratch.. Any help much appreciated for this very frustrating issue
