Does anyone have any ideas what to do to fix it ???,if not ill just take it to apple store.
Looking at the screen of your phone, the small rouded rectangle hole to the right of your charging port is the microphone. If you have damage around there your microphone might have been harmed. Try to download a voice recording app and see if your iPhone picks up audio and go from there.
