How to Fix an iPhone 8 Plus Microphone that’s not Working


There are two principal reasons why the microphone is not working on your iPhone 8 Plus. Either the microphone is busted due to hardware damage or couldn’t get to work as intended because of software glitches. For the first possible reason, you have no other choice except to have your iPhone checked or potentially fixed by a technician.

Moreover, if the microphone issue you are dealing with is attributed to a software glitch, you still have the opportunity of getting it fixed at home. All you need is to try performing some applicable workarounds to troubleshoot software problems that caused the microphone functions to fail at the moment. So read on and get some input on dealing with this problem on your iPhone 8 Plus.

How to Troubleshoot iPhone 8 Plus with a Microphone That’s not Working?

Before you investigate, test, and check your iPhone’s amplifier, you have three microphones, the rear microphone, the front/receiver microphone, and the bottom microphone.

To test the front/receiver and rear microphones, shoot two short videos. First, utilize the front camera to make the principal effort and the back camera for the subsequent shot. After that, play them back. If you hear sound in the front and back camera recordings, the video’s receiver is working fine.

To test the third microphone, open the Voice Memos application and then record another update by squeezing the large red button on the screen. Play the memo back, then see if you hear the audio. If it’s audible, the bottom microphone is working.

Clean the Receiver

You can revert the recent changes you’ve made back to their initial configuration to fix the problem. But if you can’t remember exactly what has changed or which from among the modified settings has caused the microphone problem to stop working, you can reset all settings on your iPhone 8 Plus. This will eradicate all your current settings and reestablish them to defaults without impacting any information/data you have stored on the internal memory of your iPhone. Here’s how it’s done:

  • Open the Settings application.
  • Tap General.
  • Scroll down, then tap Reset.
  • Tap to choose the Reset All Settings alternative.

After the reboot, test whether the amplifiers are now working appropriately. If the problem persists, try the next workaround.

Update iOS to the Latest Version Available

Software updates likewise contain bug fixes beside new features. If certain bugs set off the microphone issue, installing the most recent iOS version will like to fix it.

Here’s how to check for available software updates on your iPhone 8 Plus:

  • Tap General.
  • Tap Software Update.

For example, perhaps some tough bugs messed up the audio system of your iPhone, and so none of the microphones are working as a result.

However, you will also lose your personal information and other important data you have stored on your device. That being said, creating a backup is recommended. Should you wish to proceed, follow these steps to factory reset your iPhone 8 Plus through the Settings menu:

  • Open the Settings application.
  • Tap General.

  • Finally, tap the option to confirm master reset.

Hold up until the reset is done and your iPhone reboots. Then, complete the initial setup and utilize your gadget as you usually do. Then, test the microphone to check whether the issue is now fixed.

Other Suggestions

  • Remove any accessory that is plugged into the headphone jack. Sometimes, this may cause conflict with certain audio functions.
  • Ensure the microphone and iSight mic isn’t obstructed by your fingers while holding the telephone or recording a video.
  • If you utilize screen protectors, films, or cases, particularly non-Apple made, try to eliminate them. There’s a chance that any of these accessories can cover the microphone, iSight mic, or iPhone receiver, thus disrupting audio output.
  • If the microphone doesn’t work just when utilizing FaceTime, confirm and ensure that FaceTime is accessible in your location.
  • Contact Apple Support or visit an Apple-approved assistance location close by if your iPhone 8 Plus amplifier is not working after playing out all earlier workarounds.

Your iPhone may have obtained some physical or liquid damage that caused the microphone system to get busted. At this point, your next best hope to get the microphone working again is service. Don’t forget to avail of warranties if your device is still eligible. It can help you save some dollars on service charges.
