iPhone microphone not working? Repair guide

If your iPhone microphone is no longer working during calls, you know how annoying that can be. From the iPhone X to the latest models like the iPhone 17 Pro Max, this problem can affect any user and impact call quality. At iServices, we understand how important a properly working microphone is to stay in touch with the people who matter most.

This article aims to help identify the most common causes why the iPhone microphone does not work during calls and to provide practical solutions. In addition, we explain when it is advisable to seek specialized technical assistance so that your device can return to perfect condition.

Causes why the iPhone microphone does not work during calls

Obstruction or dirt in the microphone

Due to daily use, the iPhone microphone can accumulate dust, dirt, or debris that blocks the sound. This interferes with voice recording, which prevents the person on the other end from hearing you during the call.

Software problems or incorrect settings

iOS updates or conflicting apps can disable the microphone for calls. Sometimes specific settings, such as the use of Bluetooth accessories or microphone permissions, affect the component's operation.

Hardware defect in the microphone

Physical damage, such as drops or exposure to liquids, can damage the iPhone's internal microphone. This type of problem requires a technical assessment to confirm whether replacement of the part is necessary.

Interference from accessories or apps

The use of cases, screen protectors, or accessories that cover the microphone, as well as some apps that have access to the microphone in the background, can prevent it from working properly during calls.

Step-by-step solutions

Gently clean the microphone

• Identify the location of the microphone on your iPhone (usually at the bottom near the charging port).
• Use a very soft brush or a wooden toothpick to gently remove any accumulated dirt or dust.
• Avoid using metal objects or liquids that could damage internal components.

Restart iPhone and update iOS

• Press and hold the side button and one of the volume buttons until the power-off slider appears.
• Turn off the device and wait a few seconds.
• Turn the iPhone back on.
• Go to Settings > General > Software Update and update iOS to the most recent version available.

Check permissions and disable Bluetooth

• Go to Settings > Privacy > Microphone and confirm that apps have permission to use the microphone.

Why does my iPhone microphone only not work during calls?

This may be due to specific system settings during calls, interference from Bluetooth accessories, or software problems that only affect operation during phone calls, and not during recordings or other apps.

How can I test if my iPhone microphone is working correctly?

You can use the Voice Memos app to record a message and play it back. If the recording is clear, the microphone is working and the problem may be related to calls or software.

Can cleaning the microphone damage the iPhone?

If performed carefully and with the correct tools, cleaning does not cause damage. Avoid using liquids or metal objects that could introduce moisture or cause a short circuit.
