How to force the phone earpiece to be used when an external microphone (headset) is connected?



  • I want to keep the sound output on the phone, the earpiece or the loudspeaker as it is normally when I connect an external microphone. It's detected as a headset so they're disabled as well as the microphone.

    My internal microphone is dead, and I want to use this small jack microphone I have.

    Is there an obscure setting, working app, or adb command for this?

    I tried a few apps, but none of them worked. "Lesser AudioSwitch" got the closest. The microphone works so does the phone speakers, EXCEPT when I start a phone call, then the microphone input stops working and I'm not heard by the person I called. Which would be the main reason to use the microphone...



  • Short answer: Unfortunately, you can't do this on Android since android doesn't come with separate mic and sound choices. There might be solutions if your device has root access though
