Unhappy [Q] people can't hear me after screen replacement.

I got a new screen (glass, digitizer and lcd) so
After everything has been put in place, I tried the phone and everything seemed to work. Vibration, connection, sound, and touch screen. So I made everything close and I first set on my phone.
I was called but people do not hear me. Tried again, but people still do not hear me. When I got on whatsapp a voice message recorded but that just working so the mic is working fine. on speaker they can hear me to.
I double checked the cables but everything looks good. I also did a factory reset but no one can hear me..
Anyone know whats my problem?
I can replace the whole cable system witch is atached to the mic but i dont know if that is the problem because the mic work…
