For that you have to download CUBE CALL RECORDER. After opening the app, go to WhatsApp and call the person you want to talk to. If you see the Cube Call widget, it means that your phone is being recorded. If your phone is showing an error then open CUBE CALL RECORDER once again and go to APP settings and click on Force Voip in voice call. Call WhatsApp once again and the call will be recorded after it is connected. If the CUBE CALL RECORDER does not appear it means that your call cannot be recorded.
