My iPhone not recording any sound on home videos

An interesting situation. That goes to show that there’s nothing wrong with the microphone which is good. But I don’t know where to proceed with this based on my personal experience. I would suggest you reach out to Apple Support for further assistance:

• Telephone: Contact Apple for support and service - Apple Support. 
• Online #1: Start your request online. 
• Online #2: Support
• Live Chat: Live Chat with an Apple Advisor in Messages.

Take care John, and good luck.

Hi all,

I believe now that the microphone for the rear camera is blocked. (I can hear noise when i scratch the area near it.) Does anyone know how to clean it? Can it be removed?

Please don't suggest taking it in for service. It's not worth spending any money on.

Thanks,

... john

I think you can get the speakers cleaned free of charge at an Apple Store. But call in and ask to make sure.

Are you using a case? If so, remove the case and try a recording again. Screen protectors sometimes block microphone openings as well.

You’re welcome and I’m glad you were able to resolve the microphone issue.
