Microphone goes silent during call (hardware problem)

Hi guys, I had this problem for a long time, i want to make the story very short. My microphone becomes silent after 1 minute of use. I used the stock voice recorder to check it without the need to call someone. People get annoyed because they can't speak to me. Sometimes the microphone is silent from the very beginning of a conversation. I hear them well but they can't hear me. Once i've changed the mic flex cable/usb port plate and it looked like it worked fine for about a month. Then the problem came back. Could it be the motherboard? Did anyone experience something similar? I had to repair my camera right after buying it second hand. The technician told me the phone was in touch with water after he replaced the back camera.
