If I'm correct the upper mic is the one that records the sound for videos and the speaker during calls.
This mic is not working. What can I do to fix this?
The mic works perfectly during calls (no speaker), while recording audio on whatsapp, and recording voice memos. So I know the problem is the upper microphone and not the lower microphone.
How do I fix it?
Thank you.

I have had this issue three or four times, usually after I installed an app like voice recording, or recently, streaming radio. So far, rebooting has almost always fixed it. Once, I did have to delete the offending app.

The iPhone 4 has this as a common issue and most of the time it can be fixed with a simple hard reset.

The Proximity Flex cable for the GSM iPhone 4 contains the top mic, so if that is your problem changing that flex cable should solve the issue.

I used to use my iPhone 5s to record a show. Even though the show was extremely loud, my phone still couldn't record any sound. I searched the internet and found one answer: tear off the plastic cover on the back of the phone. I found there was a tiny hole besides the camera, which I assume it's where the audio inputs. I did record sound ever since I tore it off.
