Fixing crackling earpiece and/or distorted sound during calls on iPhone X after iOS 13.2.3 update

When your phone is acquiring a poor signal from the network, this will also cause your phone to create unwanted sounds during calls. Thus, you need to make sure that you have enough network signal strength before troubleshooting your iPhone X device. If it does, dump out software-related factors that prompt your phone to produce distorted sound during calls using the solutions we have listed below.

First solution: Restart (soft reset) your iPhone X.

Various types of post-update errors can be corrected by restarting your phone. Random software glitches that might triggered your phone to produce unwanted sounds while on call should be cleared out after the quick restart. Here is how:

  1. Press and hold the Side/Power button and either Volume Up/Down button simultaneously.
  2. When the Slide to Power Off command appears, release both buttons.
  3. Then drag the power off slider to the right to turn off your phone.
  4. After 30 seconds, press and hold the Side/Power button again until the Apple logo appears.

Wait for the phone to be completely on. Then make a test call to check if the distorted sound during has been eliminated. Otherwise, continue to the next potential solution.

Second solution: Forget saved Bluetooth devices and disable Bluetooth feature.

Other possible factor that may lead your phone to have distorted sound during calls is being connected to a corrupted Bluetooth connection. To rule this out, forget or delete saved Bluetooth devices and turn off Bluetooth to prevent your phone from automatically connecting to any Bluetooth accessories within range. Here is how:

  1. From Home, go to Settings.
  2. Select Bluetooth and make sure that it is enabled.
  3. Select the name of the Bluetooth device that you opt to delete.
  4. Tap the information “i” icon next to the Bluetooth’s name.
  5. Select Forget This Device option, and then follow the on-screen prompts to confirm the action.

Do the same to the rest of the saved Bluetooth devices. After you have successfully deleted the Bluetooth devices, head back to Settings->Bluetooth and then toggle the switch to disable the feature.

Third solution: Toggle the Airplane Mode on and off again to fix crackling earpiece, distorted sound during calls after iOS 13.2.3 on iPhone X.

If the previous solution failed to fix the audio problem during calls on your device, might as well try the Airplane Mode trick. If the underlying cause is due to random cellular errors, then this tweak can securely fix the issue. Here is how it’s done:

  1. Tap Settings from Home.
  2. Select Airplane Mode.
  3. Tap the Airplane Mode to enable the feature. Once the feature is ON, your phone’s wireless radios like Wi-Fi and Bluetooth will be disabled.
  4. Restart (soft reset) your iPhone X while Airplane Mode is on.
  5. Then head back to Settings->Airplane Mode and then toggle the switch to turn the feature off again.

Wait until your phone reconnects to the cellular network. Once your phone is already showing excellent cellular network signal, check the audio quality of your iPhone X by making a test call.

Fourth solution: Reset all settings.

Faulty system settings due to automatic overrides transpired during the iOS update can also cause the audio problem to occur. Being said, it is ideal to delete current phone settings including the erratic ones. This reset does not result in a complete data loss. Hence, a back-up for your files isn’t necessary at this time. To carry out reset all settings on your iPhone X device, follow these steps:

  1. Go to Settings from the Home screen.
  2. Select General.
  3. Scroll down to and tap Reset.
  4. Select Reset all settings option.
  5. Enter your device passcode, when asked.
  6. Finally, select the option to confirm reset all settings.

Once the reset has been completed, your phone will reboot by itself. By then, proceed to enable features to use them again and configure the settings according to your preferences. Then make a test call to check if the earpiece is no longer crackling. If the audio is still distorted during calls, you would now need to perform a more drastic move which is to erase your iPhone X and restore it to factory default settings. Check out the next solution to see how it’s done.

Fifth solution: Factory reset your iPhone X to fix crackling earpiece, distorted sound during calls after iOS 13.2.3.

Tough bugs and complex system errors may have triggered your phone’s audio functions to fail. To rule out these factors, you need to wipe everything from your phone’s internal memory. However, this reset will not only obliterate such iOS bugs and major software glitches but also the important files saved in your phone’s storage. Hence, creating a back-up for your files beforehand is a must. Once done, you can carry out factory reset via iTunes using a computer or through your phone’s menu settings itself. If your phone screen is still responsive, we recommend to do the reset via your phone’s settings. Here is how:

  1. Launch the Settings app from the Home screen.
  2. Select General and tap Reset.
  3. Select Erase all content and settings from the given options.
  4. If prompted, enter your device passcode and then continue.
  5. Then select the option to confirm the factory reset.

After the factory reset, follow the start-up wizard to set up your phone as new again. Then check if the distorted sound during calls issue is already fixed.
