Hey sarai299.
It sounds like you might be having an issue with one or more of the microphones on your iPhone. If the microphones on your iPhone aren't working has some great steps that you can try on your own if you want to do some troubleshooting, but you may need to get in touch with Apple Support to see about having your device inspected for potential service. Here are some things you can try on your own:
" Clear the microphones
- Remove any screen protectors, films, or cases from your iPhone.
- Clear any debris from the openings of your iPhone. "
And a few others.
"If you want to try more steps on your own
If you prefer, here are some more steps you can try on your own. You might still need to contact Apple Support after following these steps.
If people can't hear you on phone or FaceTime calls
- Open the Voice Memos app.
- Tap the Record button
, speak at the bottom of your phone, then stop the recording. - When you play back the memo, you should hear your voice clearly.
If people can't hear you when you're using speakerphone
- Open the Camera app.
- Record a video while speaking at the top of your iPhone.
- Tap the camera chooser
to switch to the other camera. Then record another video while speaking at the top of your iPhone. - When you play back the videos, you should hear your voice clearly.
If the microphone doesn't work in a specific app
- Go to Settings > Privacy > Microphone.
- Make sure that the app is enabled.
- If the app has permission to access your microphone, or if it isn't listed, contact the app developer."
If none of these steps are helpful for you, you can get in touch with Apple using the link in the middle of this reply for more help.
Take care.
