My mic doesnt work during Bluetooth calls. I can hear the other party, but they can't hear me. I have unpaired and repaired to multiple bluetooth devices. I did a factory reset of the device. I switched off OK Google detection from any screen (as per a suggestion on another thread) I can still stream audio using Bluetooth, and I know that the mic works while connected to bluetooth as I can use voice controlled navigation etc.
The bluetooth used to work, it stopped a few weeks ago, perhaps an update?
Any suggestions?
