Troubleshoot microphone that stopped working on iPhone after installing iOS 13.3

There are several possible reasons why a microphone is not working on your iPhone. Factors like bugs on software updates, sound hindrances like accumulated dust and dirt on the phone’s mic, or using third-party applications can cause this problem. If your iPhone is connected to a headphone, it may also cause microphone issues. 

You may check for possible dirt build up on the iPhone’s microphone or disconnect headphones connected on your device. If you’re using an iPhone case, try removing it as it may block the mic on your device. If you’re microphone is still not working, perform the steps below as they’re suited to deal with software-related problems that causes the microphone to stop working. 

First solution: Reboot your iPhone. 

Restarting the device after an update often clears minor software glitches and refreshes the system. It could also stabilize the phone’s performance by implementing necessary changes from the recent iOS update that are not yet applied on the phone’s system. This might easily fix the not working microphone on your iPhone.

Soft reset is the most basic and common reboot method. Here’s how it’s done: 

  1. Press and hold the Power/Side button and either of the Volume buttons simultaneously for a few seconds. 
  2. Release both buttons once Slide to Power off prompt appears on the screen.
  3. Drag the Power off slider to the right to turn off your phone.
  4. After 30 seconds, press and hold the Power/Side button again until you see the Apple logo.

Aside from a soft reset, you can also reboot your device by performing a force restart. Here are the steps: 

  1. Press and release the Volume Up button quickly.
  2. Press and release the Volume Down button quickly. 
  3. Lastly, press and hold the Side button for a few seconds until you see the Apple logo.

Allow your phone to complete the reboot process then check if the microphone is already working. 

Second solution: Update all apps on your iPhone. 

Outdated app versions can also bring microphone errors on your iPhone as they could create conflicts on the phone’s system. To remove in-app errors that could bring havoc on your device, update all apps on your iPhone as they will fix certain errors and improve the apps performance. 

To do that, follow the steps below: 

  1. From the Home screen, tap on App Store to open it. 
  2. Tap on Today tab at the bottom. 
  3. Then tap on the user profile icon on the top right corner of the screen. 
  4. You should see the account details. 
  5. Scroll down to the Available Updates section. 
  6. Tap on Update next to the app to update individual apps.
  7. Tap on Update All to update all apps simultaneously. 

After updating all apps on your iPhone, reset your device to implement necessary changes and refresh the system. Once it’s up and running, check if you’re able to use the microphone this time. 

Third solution: Uninstall unused apps on your iPhone. 

If there are unused third-party applications on your iPhone, they consume space and memory on your device. Uninstalling them should enhance the phone’s performance as it will free up some space on your phone’s internal memory. This will also remove corrupted files and data that may have been causing a microphone problem on your iPhone after iOS 13.3 update. 

Here’s how to uninstall the unused apps: 

  1. From the Home screen, tap and hold on an app icon until the icons start jiggling. 
  2. Tap the X on the app you want to delete.
  3. Select Delete to confirm the deletion of the selected app. 
  4. Perform a restart on your iPhone.

After the reboot process, test your microphone if it is already working by recording a voice on your device. If you can hear a voice after recording, that means the issue has been fixed. If not, proceed to the next solution. 

Fourth solution: Reset all settings on your iPhone. 

Settings that have been invalidated through iOS overrides can cause relevant symptoms to occur and may have been the reason why you’ve got a non-working mic on your iPhone after the update. Performing an all settings reset will restore all customized settings back to their original state and removing any incorrect information due to iOS overrides. This will not affect the phone’s internal memory, so there’s no need to create backups. 

To perform this procedure, here are the steps to follow: 

  1. Access Settings from the Home screen. 
  2. Tap General.
  3. Scroll down to and then select Reset
  4. Tap the Reset All Settings option.
  5. Enter your device passcode once prompted.
  6. Then tap to confirm all settings reset. 

Your phone will reboot automatically once the reset process is done. As soon as it boots up, test the microphone if it is already working as intended. 

Fifth solution: Restore your iPhone to its default factory configurations. 

Your iPhone might have been affected by a severe error which could nullify basic procedures. For that case, you’ll need a stronger solution like performing a factory reset that could erase stubborn glitches inflicted by the recent software update. This process will delete all contents on your device and revert your iPhone to its original factory settings. 

Before you execute the steps below, make sure to create backups of your important files via iTunes or iCloud beforehand. That will allow you to retrieve important information afterwards. If you’re ready, here are the steps: 

  1. Access Settings from the Home screen. 
  2. Tap General.
  3. Scroll down to and then select Reset
  4. Tap the Erase all contents and settings option.
  5. Enter your device passcode once prompted.
  6. Then tap to confirm all settings reset.

An automatic reboot will also occur once the reset is completed. Set up your device like a new one and check if the microphone not working problem has been resolved. 

Sixth solution: Perform a Recovery mode restore on your iPhone. 

Random bugs from software updates could impose threats on your device and may cause complex system errors. This might have been the case on why the microphone not working problem persists up to this point. For that matter, you may perform an advanced solution that should help  you deal with this issue. 

To execute a recovery mode restore, you’ll need a Mac or Windows computer with the latest iTunes installed. It is also recommended that the computer is running on the latest operating system that is compatible with your iPhone. If all requirements are met, here’s how to run a recovery mode restore on your iPhone: 

  1. Using the supplied USB/Lightning cable, connect your iPhone XS to the computer then open iTunes on your computer.
  2. Press and release the Volume up button quickly.
  3. Press and release the Volume down button quickly.
  4. Then press and hold the Side button until you see Recovery Mode on your phone. Do not release the Side button if you’ll see the Apple logo screen as you will need to enter recovery mode to restore your device.
  5. Once iTunes prompts you to Restore or Update, select Restore. This will allow iTunes to download the software for your device. Your phone will exit recovery mode if the download takes more than 15 minutes. If that happens, just repeat the steps to enter recovery mode again. 

Follow the rest of the on-screen instructions to complete the process. Once done, verify if your iPhone’s microphone is already working fine.
