How to fix static or crackling noise coming from the iPhone 8 earpiece during FaceTime and phone calls? (easy steps)

Late September of last year, a number of iPhone 8 and 8 Plus users have reported an issue regarding the earpiece that’s making static or crackling noise during phone calls or when using FaceTime. The problem’s occurrence was in a form of sharp noise sound that pops at the very edge of the iPhone’s earpiece. Although it was not totally disruptive during the phone call, it sounds a bit disturbing and annoying. Apple has later on admitted and confirmed that they’re aware of the problem and that they’re team is already working on a fix to be embedded into a minor follow-up firmware update. The said update that’s bringing in the fix patch was iOS 11.0.2.

What causes your iPhone 8 to make static or crackling sound during phone calls or when using FaceTime?


Apparently, the problem on static noise or crackling sound on the iPhone 8 and iPhone 8 Plus was related to the software. Unless it occurred after you’ve dropped your iPhone or got it wet. Should the latter instance has happened, you’ll need to consider a possible hardware damage causing the same problem to occur on the iPhone. But if neither of that happened, your chances of fixing the problem without taking to a service center are higher.

Usually the very source of static noises is from either the speaker on the bottom or earpiece of your iPhone. Regardless of how advanced the iPhone 8 hardware is built, the iPhone speakers are still susceptible to damage. Unfortunately, a damaged speaker is among other problems that cannot be fixed at home. But before you run off to the Apple Store, you may try some workarounds to rule out the possibility of the problem being triggered by software malfunctions.

Considering that what you are dealing with is indeed a software issue, I have mapped out some helpful solutions for you to try on. Feel free to refer to any of the following procedures should wish to troubleshoot the problem on your iPhone 8 at this point.

Don’t forget to make a test call after performing each solution so that you’ll know if the problem has been resolved or not. Proceed to the next applicable solutions if necessary.

Workarounds to deal with crackling or static noise on your iPhone 8 during FaceTime and phone calls

The following walkthroughs are deemed generic solutions to cracking sound or static noise inflicted by software glitches.

First solution: Reboot your iPhone (soft reset).

If this is the first time you have encountered the problem, it’s probably just a minor glitch on the FaceTime app or Phone app. Minor and random apps glitches are often rectified by a reboot or soft reset. If you haven’t already, restart your iPhone or do a soft reset with these steps:

  1. Press and hold the Side button or Power button for a few seconds until the Slide to Power Off screen appears.
  2. Drag the slider to turn off your iPhone completely.
  3. After 30 seconds, press and hold the Side button or Power button for a few seconds until the Apple logo appears.

Wait until your iPhone boots up completely then try to make a test call to see if the problem has been resolved. To ensure that everything is okay, try to do a test call at least three times from your other phones or devices.

Second solution: Test to see if your iPhone speaker is working.

It is crucial to determine whether or not the problem is on the speaker itself. It could be that the speaker is not working as intended. To find out, you can carry out a speaker test with these steps:

  1. Tap Settings from the Home screen.
  2. Tap Sounds or Sounds & Haptics.
  3. Drag the Ringer and Alerts slider up or down several times.

If you don’t hear any sound from your iPhone as you drag the ringer, your speaker is likely not working and needs service. You’ll need to contact Apple Support in this case.

If you hear sound from your iPhone as you drag the slider, proceed with the next steps.

Third solution: Turn Off Do Not Disturb (DND).

Do Not Disturb is a feature used to filter incoming calls. As the name implies, DND is an iPhone feature that is used to silence calls, alerts sounds and notifications that you receive while your device is locked. It is also used to schedule when to allow calls from certain people. But there are some instances when the iPhone would act a bit odd when Do Not Disturb is on. If the crackling or static noise occurs on your iPhone 8 when DND is enabled, try to turn it off then see what happens when having Phone calls or FaceTime with DND feature disabled on your iPhone 8.

You can turn Do Not Disturb on or off through the Settings menu and the Control Center.  

  • To turn off DND using the Settings menu, go to Settings-> Do Not Disturb menu and then tap the switch to turn it off.
  • To turn off DND from the Control Center, just open the Control Center by swiping up from the bottom of the screen. Look for the Do Not Disturb icon that looks like a crescent moon. Tap the icon to turn DND off.

You’ll know if DND of disabled if the crescent icon appears in grey color.

Also verify and ensure that your iPhone is not set to silent mode. For starters, the iPhone has a Ring/Silent switch that is located on upper left corner. Move the switch forward or towards the iPhone screen to set the device to ring.

Fourth solution: Close out all apps that are running in the background

When you open and use an app on your iPhone, that app will stay running in the background or standby mode unless you quit it. The more apps you use, the more apps are in standby mode. While this can offer some advantages especially when multitasking, sometimes any of these apps can cause conflict or affect certain functions on the iPhone especially if any of them gets corrupted or crashes. To prevent this from happening, you can quit all apps in standby mode then do a test call without any app running in the background. Here’s how to quit apps on your iPhone 8:

  1. Load up or open the App Switcher by pressing the Home button for a few seconds.
  2. Go to the apps preview then swipe up on the app’s preview then flick it up and off the screen to quit or close.

Alternatively, you can use a gesture to launch multitasking on your iPhone 8 and close or quit apps with these steps:

  1. Press firmly on the left edge of your iPhone’s screen.
  2. Move that same finger to the center of the screen.
  3. Swipe up on the app preview that you want to quit.
  4. Then flick it up and off the screen to close.

If the problem occurs after installing a new app or downloading a new content, then that’s most likely the culprit. Try to uninstall the suspected app or downloads then make a test call on your iPhone 8. If the problem persists even without the suspected app, it might be a more complex issue within the iPhone operating system. At this point, your next option would be a system restore.

Fifth solution: Restore your iPhone 8.

More complex software issues including those that are caused by a faulty update on the iPhone often require a system restore in order to be resolved. There are three types of system restore you can do on your iPhone including the standard restore, recovery mode restore, and DFU mode restore.

A standard iOS restore is carried out using iTunes on a Windows or Mac computer. To get started, you’ll need to connect your iPhone to the computer, open iTunes, then click the button to Restore your iPhone to a previous iOS backup. If you haven’t already, you may also opt to click on Update in order to install the latest software update for your device. Then follow the onscreen instructions to finish the entire process.

Recovery mode restore is also done through iTunes but in this case you will have to put your iPhone in recovery mode to restore iOS in recovery state. A step-by-step guide on how to perform a recovery mode restore on iPhone 8 is available in our Tutorials page so feel free to visit that page if you need further assistance in the process.

The last type of system restore called DFU mode restore is considered the most in-depth type of restore you can do on your iPhone. It is usually performed by Apple technicians at the Genius bar. Putting your iPhone 8 in DFU mode allows your device to communicate with iTunes without loading the operating system or bootloader. Once you’ve successfully entered DFU mode, you can proceed with iOS restore.

Again, you may refer to our comprehensive walkthroughs on how to perform a recovery mode restore and DFU mode restore on your iPhone 8 whenever needed.

If none of these is able to fix the problem and that your iPhone 8 still makes crackling sound or static noise on random calls or when using FaceTime, then your device might need service. At this point, you can set a trip to an Apple Genius bar nearby and have a technician diagnose your device. Or you can also contact Apple Support for other options and recommendations. If your iPhone 8 is still under warranty, then you might as well consider availing warranty instead.
