iPhone 5S no mic during normal call - Speaker works
 

Hi guys, i face a problem with an iPhone 5s. When i call or got called i can't talk normally on the phone, just on speaker. I tried to talk with Siri and it works. I tried to record the voice, doesn't work. I changed the bottom microphone, doesnt work. Any solution?

Siri works with the front flex mic. Your problem is with the dock mic. Try an other dock and check FL49 next to the dock connector if it is not broken or missing
