After a month I installed this app again. But call recording stopped warking. The app just make a silent sound file (which I can play - but is silent). I also tried other call recording apps, and the result is the same. I tried voice call, uplink, downlink options, and the results is the same - on all apps I tried. Only when I choose mic as a recording source the sound is recorded, but only mine obviously.
I am running cyanogenmod (kitkat 4.4.2) on Samsung s relay with root access.
Any ideas what might be wrong?
