My iPhone 7 is having this weird issue where the microphone isn’t working and the software knows it’s not working like when you record a video the button to turn the sound on in the photos app is Grayed out. I’m pretty sure it’s not software because when you are connected to something with a microphone through Bluetooth you can use that microphone but there is no option to switch back to the internal microphone. Is this a simple open the phone up and put in a new microphone or is there something wrong with the logic board? Thanks!!

Hi!
From what I understand, this was a pretty common problem with the iPhone 7.
If you're sure it's not the software component, I recommend taking the phone to the nearest service center for diagnostics (you'll most likely have to replace the Audio Chip).
If you have time and patience, you can try doing a hard reset, but I don't think this will help.
