Chosen Solution
Hi All! What does it mean when the microphone works fine when using the back video camera, but when you switch to the front camera the microphone input is quiet and muffled? If you Google the issue it’s apparent that lots of people have experienced this, but there doesn’t seem to be a clear solution. Thanks! John
IMO it means the front mic part of the front camera flex cable is not recording sounds like it should. It could be that A/ the mesh covering the ear speaker and front mic is clogged, or B/ the cable is improperly seated, or C/ the mic or cable carrying it is damaged. I’d start with A/, pierce the mesh of the ear speaker with a fine needles ~3 times in the middle of the mesh. Don’t let it in more than ~1mm to avoid disturbing anything in there. Then test the mic. B/ If no improvement, I’d use this guide until step 11 to disconnect then reseat the front camera cable. This may help, although not very likely. C/ Change the front camera flex cable following the guide here above all the way to the end. Note: if issue is a clogged mesh, it can be changed using that same guide here above to remove the front cam flat cable (like in option C), after which push the mesh in, from the outside towards the inside of the screen using a flat plastic tool. Get a replacement mesh from eBay or just peel off the top layer and put the rest back in. It’s a bit of a pain to replace that mesh and there is always that inherent risk to every repair to damage the phone or screen.
Looks like noise cancellation is “on” in your settings. Go to settings>General>Accessibility. Right at the bottom is Noise Cancelation and my guess is that it’s “on”. Turn it “off” and Bingo, you’ll be hearing sound on recordings again.
Try this Settings > Camera> turn off Record Stereo Sound The muffledness went away for me

I have the same issue and thought it was the phone. Downloaded a third party camera app for better quality video and low and behold, it fixed the front mic issue. if i use the iPhone camera app its muffled. if i use the other app it works fine. so weird….
