What causes the iPhone 7 microphone problems to occur?

A common perception when it comes to microphone issues is that the iPhone microphone might have been damaged and is therefore not working or fails to function as intended. In contrary, many actual cases of microphone issues on the new iPhone 7 were tied to some software issues. For example, an audio app is malfunctioning, gets corrupted and glitches. As a result, the faulty app is not able to respond accordingly. To give you a hint on what might have gone wrong on your iPhone 7 microphone, here’s a rundown of the most common factors that can likely trigger software-related symptoms to manifest on the iPhone 7 microphones.

Faulty updates

It is highly recommended to keep an app or your device software updated not only to optimize iOS but also the get all new features and enhanced functions for your device. However contrary to what updates are supposed to do some versions also comes with certain bugs that could cause an app or device itself to become inoperable after implementing the update. One of the reasons as to why this could happen is that fact that not all devices are configured according to what the software update requires so as to keep things fine after the update installation. Generally, users would reconfigure or make changes to the iPhone settings based on their own preferences. That being said, there is a higher chance that the iPhone settings are configured in such as way that contradicts with the actual update’s required settings. This conflict therefore results t post-update issues including those that are occurring on the iPhone 7 microphone or audio functions.

Corrupt files or buggy apps

There are other cases where the problem is not actually on the iPhone 7 microphone but rather to certain audio apps or files that you are attempting to use. What usually happens is that the file or app you are trying to use with the microphone gets corrupted and not working properly. For example, when making a phone call using FaceTime or Phone app and the other end (recipient) is having a hard time hearing your voice as it sounds so distant, static, keeps cutting out and the like. In this case, it could be that the app (FaceTime or Phone) gets corrupted and is not working as intended. It could be on your end or the recipient’s end for that matter. To isolate whether or not the problem is on the microphone or certain apps, try to test the iPhone microphone using different applications and compare the results.

Misconfigured audio settings

With the iPhone’s default settings, everything should work perfectly fine. However, given that users would tend to change anything they would want to modify on the iPhone settings, it is always possible to messed up on something. You can easily determine if the problem is caused by the recent changes you’ve made to your iPhone’s audio settings especially if the symptoms begin to show right after new changes were implemented. Needless to say, you can likewise get the problem fixed by reverting changes or configure the settings again back to its previous format.

Third-party iPhone accessories

Some users who were dealing with similar problems on the iPhone’s microphone output have found a connection between the symptoms and the use of third-party casing or relevant accessories. There are some casings that won’t actually fit the iPhone’s physical built thereby blocking the microphone components of the iPhone. As a result, problems such as static or noisy background while on a phone call as well as distant sound have manifested. If you are using a third-party casing or other iPhone accessories, then try to remove it now to see if doing so will fix the problem.

Faulty hardware

Now this is already the worst among all possible causes. A physical or liquid damage is likely to blame especially if there were prior instances of dropping or getting the iPhone wet or exposed to any sort of liquids. Unfortunately in cases like this, a tech service would already be necessary. Your chance of getting the iPhone 7 microphone problem fixed can only be possibly obtained by taking your device to an authorized service center and have a capable technician further assess your device for any signs of hardware damage.

Solutions and Workarounds to fix iPhone 7 microphone problems

Considering that the hardware is not to blame or the microphone problem you are dealing with is not due to some sort of damages to the iPhone’s physical components, you can attempt to fix it on your end. To assist you further in doing so, we have highlighted some potential solutions as well as recommended workarounds used by other iPhone users who have dealt with similar issues on the same device. Feel free to refer to these methods whenever you need them.

If you are all set to begin troubleshooting the problem, then go ahead and give any of the subsequent solutions a try. Be sure to test your device after completing each method to find out if the problem is already fixed. If not, then proceed to the next applicable solution.

Before you begin performing any troubleshooting procedures, make sure that you’ve already done performing or verifying the following:

Step 1. Check and ensure that the iPhone’s microphone and headphone jack are free from dust, dirt or any debris.

You may need to clean up these parts as dust and dirt can also block the microphone and thereby results to unusual or unwanted sound quality output from the microphone. If necessary, use a dust blower, toothpick or needle to clean up these parts.

Step 2. Try to remove any accessories connected to your iPhone 7 headset jack or headphone.

These too can affect the sound quality produced through the headset jack. Doing so will also rule out the possibility that something might have been blocking the headphone jack and preventing the sound from coming out clearly.

Step 3. Check and ensure that the network connection is all good.

This is a must do especially if you’re having trouble with the microphone audio that keeps cutting out during a phone conversation. Sometimes, it is not the microphone that is causing the problem but rather triggered by the intermittent or unstable network connection.

Step 4. Test the iPhone 7 microphone.

If the issue on the primary microphone, which is located at the bottom of the iPhone, then you can use the apps like Voice Memos, Siri, Camera, and FaceTime for testing. Here’s how to test the microphone using these applications.

Testing the microphone with Voice Memos:

 

  • Open the Voice Memos app.
  • Tap the Record icon. Doing so will instigate or start voice recording.
  • To record your voice, speak clearly into the primary microphone. Also make sure that you speak with acceptable loudness.
  • To stop the recording, tap the Stop/End icon.
  • Now listen to your voice recording by tapping on the Play icon.

 

If you can clearly hear your voice recording, then it means that the primary microphone is working fine.

Testing the microphone with Siri:

Another alternative app you can use to set the iPhone 7 microphone is Siri. It is a popular iOS app that is mainly used to process voice input commands from end-users. So instead of tapping or typing on the keypad, all you need is to speak and Siri will act accordingly.

 

  • To get started, open Siri app.
  • When Siri is running, say anything you want it to do.

 

If Siri could not get your voice inputs correctly, then try to check the microphone located near the iSight and ensure that nothing is blocking it. Do the same if other audio recordings do sound faint especially when trying to play an audio with your iPhone. Dust, dirt or debris may potentially block this microphone, causing the audio to sound faint.

Testing the microphone with Camera or FaceTime app:

 

  • Open the Camera or FaceTime app.
  • Start recording a video to playback.

 

  • Play the video recording and then see if you can hear your voice clearly during the playback.

If everything seems fine with the audio playback on FaceTime or Camera app, it means that the problem is not on the iPhone’s hardware or microphone. Thus, most probably, the underlying cause is within the software layer.
