Main microphone extremly low in calls, good in apps.

The problem: When I make or receive a call the person on the other line can just hear me like im barely whispering, often not getting a word of what Im trying to loudly get them to hear. If I talk louder and directly into the mic they can hear me better, but its not very practical.

What really bothering me is that the mic works properly in every application I have tried that involves the mic.

I know people have the same problem more or less, I just haven't found someone that describes it exactly as mine.

I haven't done much other than trying to clean the earphone jack and the cover for the mic.

What does usually makes the trick for this problem?
