Short Answer

If the mic is not working during calls on an iPhone, first check if the microphone is blocked or dirty. Restart your iPhone and make sure no Bluetooth device is connected that may be taking control of the mic. Also check call settings and volume levels.

If the issue continues, check app permissions, update your iPhone software, or reset network settings. These steps can help fix most microphone problems during calls.

Detailed Explanation:

Troubleshoot Mic Calls

Check Microphone Blockage

The iPhone has multiple microphones located at different positions. Sometimes, dust, dirt, or a phone case can block the mic.

Check the bottom microphone near the charging port and make sure it is clean. Use a soft brush or dry cloth to gently clean it. Also, ensure your fingers are not covering the mic while holding the phone during calls.

Remove Bluetooth Devices

If a Bluetooth device like headphones or a car system is connected, your iPhone may use its microphone instead of the phone’s mic.

Turn off Bluetooth temporarily from Settings and make a test call. If the mic works, the issue may be with the Bluetooth device.

Restart iPhone

Restarting your iPhone can fix temporary software problems. Turn off your iPhone, wait for a few seconds, and turn it back on.

After restarting, make a call and check if the microphone is working properly. This simple step often resolves minor issues.

Check App Permissions

If the problem occurs in apps like calling apps or video calls, check microphone permissions. Go to Settings, then Privacy, and tap Microphone.

Make sure the apps you are using have permission to access the microphone. Without permission, the mic will not work in those apps.

Test Microphone

You can test your microphone by using the Voice Memos app. Record your voice and play it back.

If you can hear your voice clearly, the microphone is working. If not, there may be a hardware issue.

Update iPhone Software

Outdated software can cause microphone issues. Go to Settings, tap General, and then Software Update.

Install any available updates. Updates fix bugs and improve overall performance, including call quality and microphone function.

Reset Network Settings

If the mic issue happens during calls, resetting network settings can help. Go to Settings, then General, then Transfer or Reset iPhone, and tap Reset Network Settings.

This will reset call-related settings and may fix issues affecting the microphone during calls.

Check for Hardware Problems

If none of the steps work, there may be a hardware issue with the microphone.

In such cases, try using earphones with a mic or connect a Bluetooth device to check if the call works. If external devices work fine, your iPhone microphone may need repair.

Conclusion

Troubleshooting a mic not working during calls on an iPhone involves checking blockage, Bluetooth connections, permissions, and software updates. Restarting and resetting settings can solve most issues. If the problem continues, it may be a hardware issue that needs professional repair.
