Due audio mistake, like lowest volume is too high and highest volume is still low, same china mtk users make settups inside enginner mode to fix same audio bugs like this.
I was trying to do same fix but could not access enginner mode with same codes from china phones, I can see enginner mode in the list of system apps so I belive is blocked or got different code to access.
I dont know if this bug will be fixed in the next update so does exist a way to work in enginner mode in razr d3?
