Check For Improvements

Once your iPhone has fully restarted, check if the issue you were experiencing has been resolved.

By following this simple restart process, you can often resolve minor software-related problems on your iPhone and improve its overall performance.

Clean The Microphone

Cleaning the microphone on your iPhone can be a quick and easy way to address issues with call quality or audio during phone calls. 

Dust, dirt, or debris can gather over time and block the microphone, resulting in muffled or distorted sound. Follow these simple steps to clean the microphone:

Gather Cleaning Supplies

You will need a soft, dry brush or a clean, lint-free cloth.

Power Off Your Iphone

Before cleaning the microphone, turn off your iPhone to avoid any potential damage.

Locate The Microphone Opening

On most iPhone models, the microphone is located at the bottom edge of the device, near the charging port.

Gently Brush Or Wipe The Microphone

Use the soft brush or cloth to gently remove any visible dust or debris from the microphone opening. 

Be careful not to apply excessive pressure or use liquids, as this could cause damage.

Power On your Iphone And Test

Once you have cleaned the microphone, power on your iPhone and make a test call to check if the audio quality has improved.

Regularly cleaning the microphone can help maintain optimal call quality and ensure your iPhone functions at its best. 

If the issue persists after cleaning, consider exploring other troubleshooting steps or seeking professional assistance.

Check For Software Updates

Ensuring your iPhone is running the latest software version is crucial for optimal performance and fixing potential bugs that might affect various functionalities, including the microphone. 

Apple regularly releases software updates to improve stability and address known issues. Here’s how to check for software updates on your iPhone.

Connect To A Wi-fi Network  

Before checking for updates, connect your iPhone to a Wi-Fi network to avoid using cellular data.

Open “Settings“: Locate the “Settings” app on your iPhone’s home screen and tap to open it.

Go to “General“: Scroll down and find the “General” option in the settings menu.

Select “Software Update“: In the “General” section, tap on “Software Update.” Your iPhone will now check for available updates.

Download And Install

If a software update is available, tap “Download and Install.” Follow the on-screen instructions to proceed with the update.

Wait For Completion

Your iPhone will restart during the update process. Wait for the update to complete, and your device will be running the latest iOS version.

Regularly checking for and installing software updates can not only fix issues with your iPhone’s microphone but also enhance overall performance and security.

Disable Noise Cancellation

If you’re experiencing issues with your iPhone’s microphone during calls, it could be due to the noise cancellation feature. 

Noise cancellation aims to reduce background noise for better call quality, but it might inadvertently affect the microphone’s performance. 

To check if noise cancellation is causing the problem and disable it, follow these steps

Open “Settings“: Locate the “Settings” app on your iPhone’s home screen and tap to open it.

Go to “Accessibility“: In the settings menu, scroll down and select “Accessibility.”

Choose “Audio/Visual”: Under the “Hearing” section, find and tap on “Audio/Visual.”

Disable “Phone Noise Cancellation“: Look for the “Phone Noise Cancellation” option and toggle it off.

Test The Microphone 

After disabling noise cancellation, make a test call to check if the microphone performance has improved.

Disabling noise cancellation might help in cases where the microphone is overly sensitive to background noise. 

If the issue persists, consider exploring other troubleshooting steps or contacting Apple Support for further assistance.

Reset All Settings

To address persistent issues with your iPhone’s microphone during calls, you can perform a “Reset All Settings.”

This process reverts all preferences, such as network settings, display settings, and privacy settings, back to their default configurations without deleting your data. Follow these steps to perform the reset.

  • Open “Settings.”
  • Go to “General.”
  • Tap “Reset.”
  • Select “Reset All Settings.”
  • Enter your passcode if prompted.
  • Confirm the action by tapping “Reset All Settings.”
  • Wait for the reset to complete.

After the reset, your iPhone will be restored to its default settings. Test the microphone during a call to check for improvements. 

Remember to reconfigure personalized settings like wallpapers and notifications.

Identify Problematic Apps

If your iPhone’s microphone continues to malfunction during calls, it may be caused by a conflict with a specific app. To pinpoint problematic apps, follow these steps

Restart Your Iphone 

Begin by restarting your device to clear any temporary issues.

Enter Safe Mode 

Activate Safe Mode by following the appropriate steps for your iPhone model. Safe Mode disables third-party apps while allowing you to test the microphone.

Test The Microphone 

While in Safe Mode, make a test call to see if the issue persists. If the problem is resolved, it indicates a third-party app is causing the conflict.

Identify The Culprit 

Exit Safe Mode and uninstall apps one by one, testing the microphone after each removal. This helps identify the problematic app.

Seek App Developer Support 

If a specific app causes the microphone problem, contact the app developer for assistance or look for updates.

By following these steps, you can identify and resolve app-related conflicts affecting your iPhone’s microphone.

Check Bluetooth Connections

Sometimes, Bluetooth devices connected to your iPhone can interfere with the microphone, leading to audio problems during calls. To ensure that Bluetooth is not causing the issue, follow these steps

Disable Bluetooth

Open “Settings” and tap on “Bluetooth.” Toggle off the Bluetooth switch to disconnect any connected devices.

Restart Your Iphone 

After disabling Bluetooth, restart your iPhone to clear any temporary glitches.

Test The Microphone 

Make a test call to check if the microphone issue is resolved after disconnecting Bluetooth devices.

Reconnect Bluetooth Devices

If the microphone works fine without Bluetooth, you can reconnect your devices one by one to identify if any of them cause the problem.

By checking and managing Bluetooth connections, you can rule out interference issues and potentially fix the microphone problem during calls on your iPhone.

Inspect For Physical Damage

Physical damage to your iPhone can significantly impact the functionality of the microphone, leading to call-related issues. To inspect for physical damage, follow these steps

Examine The Exterior 

Check the exterior of your iPhone for any visible signs of damage, such as cracks, dents, or scratches.

Look For Blockages

Inspect the microphone openings, usually located at the bottom edge of the device, to ensure they are not blocked by dust, debris, or any foreign objects.

Check Water Damage Indicators 

If your iPhone has been exposed to water or moisture, check the water damage indicators. 

They are small white or silver dots located in the charging port or SIM card tray area. If these indicators have turned red or pink, it indicates water damage.

Test The Microphone

Make a test call and pay attention to the call quality and audio. If the microphone is muffled or not working properly, physical damage could be the culprit.

If you find any physical damage, it’s best to seek professional assistance from Apple Support or an authorized service center to assess and repair the issue.
