is it possible to add settings for boost microphone volume ? Now I get reports of low volume, tested several phones , but all the same.

Thanks for letting me know! I've heard a couple other people having this issue as well.

Let's try to fix it in the Android app first (i.e. increase the volume of the audio being sent from the mic to the ESP32). If that's not possible or results in distortion, then we need to fix in the PCB by changing out the 1M ohm resistor with a lower value or a small potentiometer so it can be tweaked.

It might be worthwhile to add a DSP compressor in the android app to fix this rather than a static volume control. Maybe yoink the code from something like https://github.com/p-hlp/CTAGDRC
