Several minutes into a phone call the other party will no longer be able to hear me. After hanging up and redialing the call the other party can hear me again. This happens when I am not moving and am receiving a strong cellular signal.
iPhone 12, iOS 16
Hey Irishman56,
We'd be happy to help out. Given that you're experiencing this behavior with an iPhone 12, we'd suggest reviewing the following service program for this matter: iPhone 12 and iPhone 12 Pro Service Program for No Sound Issues - Apple Support
If sound is coming in and out intermittently, we'd suggest reviewing the steps here for further troubleshooting:
Follow these steps
1. If your device has a Ring/Silent switch, move the switch forward—toward the device's display—so that orange isn't showing. If you're using an iPad, you can also swipe down from the top-right corner to open Control Center and make sure that Silent Mode is off.
2. Open Settings > Focus > Do Not Disturb and make sure that Do Not Disturb is off.
Contact Apple Support
If you checked the sound settings and your device still has sound issues, contact Apple Support to discuss service options.
If you want to try more steps on your own
If you prefer, here are some more steps you can try on your own. After following these steps, you might still need to contact Apple Support to discuss service options.
1. Remove all screen protectors, films, or cases from your device.
2. Check the speaker opening to see if it's blocked or dirty. On iPhone only, make sure that the receiver isn't blocked or dirty.
3. If necessary, clean the speaker or receiver opening with a small, soft-bristled brush. Make sure that the brush is clean and dry.
4. Go to Settings > Sounds (or Settings > Sounds & Haptics), and drag the Ringer and Alerts slider back and forth a few times. If you don't hear any sound, or if your speaker button on the Ringer and Alerts slider is dimmed, your speaker might need service.
5. If you hear sound, try making a call with your iPhone and turn on speakerphone. On iPad or iPod touch, make a FaceTime call. If you still can't hear, or hear static or crackling, then your network or reception could be the issue. Try to call again later, or from a different location.
This is outlined further here: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support
