Thank you for the details of the issue you are experiencing with the microphone on your iPhone 5. I notice you came from the article “iPhone: Microphone issues.” Have you attempted all of the following steps?
Resolution
- Make sure nothing is plugged in to the jack connector.
- Make sure nothing is blocking any of the microphones (see the pictures below to locate the microphones on your device)
- Make sure none of the microphones is obstructed by dirt or debris.
- Turn the iPhone off and then on.
- Make sure that the latest version of iOS is installed.
- If necessary, find general iPhone hardware troubleshooting suggestions.
- For further assistance, contact Apple Support.
