When wired headset is connected to the phone, the headset mic is dead, and the phone uses the main built-in mic during calls. After starting SoundAbout app, the phone starts using the headset mic, and keep using it for a while, then returns to built-in mic.
Currently on 6.9.29, but had this problem with earlier versions as well.
