@sinarahnav30084 double check your work. Make sure that the flex cable from the sub board to the main board is properly seated and not torn etc. If in doubt, consider replacing it. The mic is soldered on the sub board.
If that does not work, you will have to check your main board. Follow the Samsung Flowchart

well if you can recheck your main board jack if its seems ok then may b problem is in new lcd unit. mic ways are passing through the main flex. may be the part has factory issue. best way to trouble shoot this is to replce lcd with new one if issue still remain then sub pcb might be faulty. for the good reason replace both at same time there is less chance that the mein board have a issue.
