How to Deal with Crackling Earpiece Sound on iPhone 12

Usually, you will experience a crackling earpiece problem if your device has been dropped or incurred any similar trauma that could damage the hardware on your iPhone. It may also be due to water damage once your phone has been submerged to water for an extended period. 

But certain cases where a crackling sound on an earpiece would suddenly occur even without those mentioned incidents. That may be due to a software bug that could occur any time as we use our iPhones. 

If you are facing the same kind of issue on your iPhone 12 that it produces a crackling earpiece sound and the phone did not incur any physical stress, then follow the procedures that I have mapped out below. 

Before you perform the steps, make sure that your iPhone’s earpiece is free from any dirt/dust or moisture that may accumulate on it. You may wipe it with a soft, clean cloth. 

First Solution: Force Restart your iPhone 12

A very simple and easy process that heals a lot of smartphone problems is by performing a force restart. It allows a system calibration that could help in refreshing the phone’s system and enhance the performance which is essential in resolving the crackling earpiece problem. Just perform a few button presses as provided below: 

  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.

Once the phone has fully restarted, try to check if you still hear a crackling earpiece on your iPhone 12. 

Second Solution: Update the Apps and check for iOS Update on your iPhone 12

There are a lot of issues that could occur on your iPhone if the apps are outdated. They impose a thread with the phone’s performance as they could easily go rogue due to app bugs. Same goes with your iPhone’s iOS. Basically, updates are being released to provide a cure to some reported bugs and helps in improving the device’s performance. 

You can check app updates by: 

  1. From the Home screen, tap on App Store to open it. 
  2. Tap on Today tab at the bottom-left corner. 
  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. 

You can check for software update by: 

  1. Access Settings from the Home screen. 
  2. Go to and select General.
  3. Tap on Software Update.
  4. Wait for the “Checking for Update” prompt to complete. 
  5. If there’s an available software update, read its description. Tap on Download and Install to apply the update on your device. 

If updates are installed on the device successfully, force restart your iPhone and then test the earpiece if it still produces a crackling sound. 

Third Solution: Reset All Settings on your iPhone 12

A crackling earpiece problem could also occur if there are misconfigured settings on your iPhone. Ironic it may seem, but settings play an important role on your device would provide an outstanding performance. One incorrect configuration could lead to a lot of problems on the device. 

To rule out the possibility of having misconfigured information that may have been causing the problem, revert all settings to their default values and options without affecting your personal information through a reset all settings procedure. 

  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. 

Just test the earpiece after the reset process has been completed to check if the problem has gone away. 

Fourth Solution: Factory Reset your iPhone 12

If the problem is not resolved by resetting all settings, then it is time to delete all contents on your iPhone, including third-party apps and some personal information. The problem might not be a simple software glitch and it needs a more potent solution. Before your do a factory reset, make sure to backup your files first. 

To create a backup via iTunes:

  1. Prepare a Mac or Windows computer with the latest iTunes installed.
  2. Connect your iPhone to the computer using the Apple-supplied USB/lightning cable. 
  3. Open iTunes on your computer. Then allow iTunes to sync with your iPhone and backup files.

Once done, perform a factory reset with these 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.

After doing a factory reset, set up your device just like the first time. Once done, check if the iPhone 12 with crackling earpiece issue has been resolved. 

Fifth Solution: Perform a Recovery Mode Restore on your iPhone 12

A more advanced solution that deals with severe software problems might be the answer to your iPhone’s earpiece issue. Recovery mode restore allows you to redownload the iOS on your phone, clearing bugs along the way. 

You will need to prepare a Mac or Windows computer with the latest iTunes installed. Also ensure that your computer runs on the latest operating system that is compatible with your iPhone 12 and it has a stable internet connection. If all requirements are met, connect your device to the computer using the Apple-supplied USB/lightning cable and open iTunes. Then allow iTunes to sync with your iPhone and backup files, if possible. Once the backup is secured, follow these steps to put your iPhone 12 in recovery mode and then restore iOS in iTunes:

  1. Press and release the Volume Up button quickly.
  2. Press and release the Volume Down button quickly.
  3. Then press and hold the Power/Side button once prompted with Connect to iTunes screen. Do not release the button when the Apple logo appears as you will need to enter recovery mode state.
  4. Once you enter the recovery mode, you’ll see either Update or Restore option.
  5. Select Restore if you want to reinstall and download iOS on your device without erasing data. 

If you are prompted by the system to disconnect your iPhone, then it is an indication the procedure is complete. Test your device and see if the issue has been rectified.
