Hey, I have an iPhone 7 Plus, and for some reason, my microphone has stopped working. I've been taking care of my phone, never dropping it or anything. The other day the microphone stopped working. What's weird is that I was filming videos outdoors, and upon looking back at the videos, the microphone stopped working in the middle of filming- I can tell the mic stopped working because the volume option when watching the video is grayed out. I tried everything I could find through YouTube videos and these forums. Even when people call me, I can't even hear them, and there's no option for speakerphone. Please let me know what I can do.

Microphones are essential parts of audio recording systems. And the audio system of an iPhone is very important for using the device and its third-party applications. That is why any sign of a faulty microphone can be devastating to the iPhone user. The iPhone microphone not working could mean that speaking over the phone with another person may be impossible. It could also mean that you cannot record audio or a video on your iPhone with sound. If you are faced with this issue, this post will show you the probable solutions to iPhone microphone not working problem.

Part 1. Why Is Your iPhone Microphone Not Working?

Your iPhone microphone is not working because your microphone hardware is broken or your iPhone's software microphone system has developed a glitch. Physical damages, especially liquid ones, cause iPhone hardware microphone faults. If there is debris or liquid around the microphone, it will hinder its right functioning. And the microphone can also be broken because you dropped the phone or its microphones were punctured. This can also be a software glitch caused by an app using the microphone. In other cases, the iPhone microphone not working can be due to a bug in the device's OS.

Part 2. How Do You Fix the Microphone on Your iPhone Not Working?

You do not necessarily have to change a microphone not working. The right approach to check and correct iPhone microphones not working on calls, apps, and others is discussed below.

1Check Covering and Dirt Around Mic

A lot of people make use of screen protectors, films, and cases. It is not wrong to use iPhone cases, films, and screen protectors but most of them are more detrimental than beneficial to your device. For instance, some of these added gadgets are why you will find debris around your iPhone microphone. Hence, you can remove them to check if they have been harboring debris around your microphone. You can use a clean, soft toothbrush or an air compressor to remove the debris.

When using compressed air, be careful to regulate the airflow so that it does not damage the internal components of your device. Please avoid using any sharp object to clean your microphone because it can damage the phone. And before you buy another screen protector or case, ensure that they are fit well with your iPhone. You will know the ones that fit if the holes align with your device's and are not covering its microphone.

2Test Your iPhone's Microphone
