Okay, so we tried that with my dad, it didn’t help. So we tried this, what “CTaramarcaz” said Microphone only working in conference/loudspeaker mode we put tapes and we also did this what “ecosepo” had done Primary Microphone not working and tired of replacing the bottom module but it still didn’t work. I can make phone calls if phone is on the loudspeaker mode (not fun at public) or if press REALLY tightly the bottom egde of my phone (around the microphone). My dad thinks the problem isn’t broken microphone, but instead there,s problem with connect between microphone and the display module(?). So thanks for everyone for your brilliant advices (even thought they didn’t work)
