The call volume and clarity on my Mi Mix (latest eu stable) is very poor. When I perform the hardware tests *#*#64663#*#* the microphone tests 5, 7, and 8 all produce clear loud sound, but test 6 "simulation call test" produces barely any audible sound. I have a hard time hearing other people when they phone me, and they complain they can barely hear me. Any solutions?
