Quick Answer: How Do You Fix a Phone Microphone?

If your phone microphone is not working, begin by identifying whether the issue is caused by software or hardware. Restart your phone, remove the protective case, clean the microphone opening carefully, test the microphone using the Voice Recorder app, disconnect Bluetooth accessories, update the operating system, and check app permissions. If callers still cannot hear your voice or recordings remain silent, the microphone, charging port assembly, audio IC, flex cable, or motherboard may require professional repair. Most smartphone microphone repairs can be completed the same day by certified technicians using premium-quality replacement parts.

Expert Tip

Never insert needles, pins, paper clips, or other metal objects into your phone’s microphone hole. Modern smartphones use extremely sensitive MEMS microphones that can be permanently damaged by improper cleaning. If debris is blocking the microphone, use compressed air or a soft anti-static brush instead. If the problem persists after safe cleaning, professional diagnosis is the safest option.

Introduction

Your smartphone’s microphone plays a far bigger role than simply allowing people to hear your voice during calls. It is responsible for voice calls, video calls, voice notes, voice assistants, voice recordings, online meetings, social media videos, speech-to-text features, and countless other everyday tasks. When the microphone stops working correctly, even the simplest communication can become frustrating.

A faulty microphone may cause callers to hear nothing at all, hear your voice intermittently, experience distorted or muffled audio, or complain about excessive background noise. In some cases, the problem only affects specific apps such as WhatsApp, FaceTime, Zoom, Microsoft Teams, or Google Meet, while in others the microphone fails across the entire device.

The good news is that not every microphone problem requires replacing the phone or even replacing the microphone itself. Many issues are caused by software settings, blocked microphone ports, Bluetooth conflicts, app permissions, or temporary operating system glitches that can often be resolved within minutes.

The challenge is identifying the real cause before attempting a repair. Replacing the wrong component or attempting an unnecessary DIY repair can increase costs and may even cause further damage to your device.

Whether you own an iPhone, Samsung Galaxy, Google Pixel, Huawei, OnePlus, Oppo, Vivo, Sony Xperia, or another Android smartphone, the troubleshooting methods in this guide apply to almost every modern mobile device.

Why Is Your Phone Microphone Not Working?

Modern smartphones usually contain multiple microphones rather than just one. Depending on the device model, different microphones are used for:

Phone calls
Speakerphone calls
Voice recording
Video recording
Noise cancellation
Voice assistants
Video conferencing
Voice typing

This means a problem affecting one microphone may not affect the others. For example, your voice may sound perfectly clear during video recordings but disappear during normal phone calls, indicating that only one microphone has developed a fault.

Microphone problems can appear gradually or suddenly. Some develop after months of dust accumulation, while others occur immediately after dropping the phone, exposing it to water, or installing a software update. Some of the most common causes include:

Dust or lint blocking the microphone opening
Water or liquid damage
Physical impact after dropping the phone
Faulty charging port assembly
Damaged microphone flex cable
Software bugs
Corrupted operating system updates
Incorrect microphone permissions
Bluetooth audio conflicts
Worn internal components
Motherboard or Audio IC faults
Third-party accessories interfering with audio

Fortunately, many microphone issues are easier to fix than people expect. Our technicians regularly diagnose devices that appear to have failed microphones but actually only require software adjustments or careful cleaning.

Before You Attempt Any Microphone Repair

One of the biggest mistakes smartphone users make is immediately assuming the microphone has failed. Professional technicians always begin with a structured inspection before replacing any components. Before troubleshooting your phone, follow these essential preparation steps.

1. Back Up Your Important Data

If your smartphone still powers on normally, create a backup before performing advanced troubleshooting. Protect important information including:

Photos
Videos
Contacts
Messages
Notes
Documents
App data
Passwords

Although microphone troubleshooting is generally safe, any advanced software recovery procedure carries a small risk of data loss.

2. Remove Cases and Accessories

Many protective accessories partially cover microphone openings without users noticing. Before testing the microphone, remove:

Thick protective cases
Waterproof cases
Phone skins
External microphones
USB accessories
Headphones
Bluetooth devices

Even premium phone cases can occasionally interfere with microphone performance if they aren’t designed specifically for your phone model.

3. Inspect the Microphone Openings

Modern smartphones often have two or three microphone holes. Carefully inspect each one under bright lighting. Look for:

Pocket lint
Dust
Dirt
Dried liquid residue
Makeup or cosmetic residue
Food particles
Damage around the microphone grille
Bent frame after a drop

Many “broken” microphones simply have blocked microphone ports.

4. Determine Whether the Problem Is Software or Hardware

This is one of the most important steps during professional smartphone diagnostics.

Software Problems	Hardware Problems
App permissions	Water damage
Operating system bugs	Broken microphone
Bluetooth conflicts	Charging port assembly damage
Voice recorder errors	Flex cable failure
App crashes	Motherboard faults
Settings misconfiguration	Physical impact damage

Correctly identifying the cause prevents unnecessary repairs and saves both time and money.

From Our Repair Bench

At iExpert Repairs, we diagnose microphone faults on smartphones every day. Surprisingly, a significant number of devices booked in for “microphone replacement” don’t actually need a new microphone. In many cases, the issue is caused by compacted pocket lint blocking the microphone port, incorrect app permissions, Bluetooth devices accidentally taking over audio input, or software glitches following an operating system update.

That’s why our technicians always carry out a full diagnostic before replacing any parts. This approach helps customers avoid unnecessary repair costs while ensuring the real fault is identified first.

Why Is My Phone Microphone Not Working?

A faulty microphone can make your smartphone almost impossible to use. You may be unable to make phone calls, send voice notes, use voice assistants like Siri or Google Assistant, join video meetings, or record clear videos. Fortunately, a microphone problem doesn’t always mean the hardware has failed. In many cases, the issue is caused by software settings, blocked microphone holes, moisture, Bluetooth conflicts, or app permissions.

Our technicians at iExpert Repairs have repaired thousands of microphone-related issues across iPhones, Samsung Galaxy devices, Google Pixel phones, Huawei smartphones, OnePlus devices, and many other Android models throughout the UK. Based on that real-world experience, we’ve created this complete troubleshooting guide to help you identify the cause and determine whether a simple fix or a professional repair is required.

Common Signs of a Faulty Phone Microphone

Different microphone faults produce different symptoms. Recognising the signs helps narrow down the cause more quickly. You may notice:

People cannot hear you during phone calls.
Voice notes record no sound.
Your voice sounds muffled or distorted.
Siri or Google Assistant cannot hear commands.
Video recordings have no audio.
Speakerphone works but normal calls do not.
Only certain apps cannot detect your voice.
Audio cuts in and out randomly.
Calls constantly switch between clear and silent audio.
Microphone stops working after a phone drop or water exposure.

Some symptoms point towards software issues, while others indicate physical damage to one of the phone’s internal microphones. Most modern smartphones don’t have just one microphone. Premium devices usually contain two to four microphones, each serving a different purpose.

Microphone	Function
Primary microphone	Voice calls
Secondary microphone	Noise cancellation
Top microphone	Video recording
Rear microphone	Camera audio recording

This explains why:

Phone calls may fail while videos still record sound.
Voice Recorder works but WhatsApp doesn’t.
Speakerphone works while normal calls don’t.
Video recordings sound perfect but calls remain silent.

Professional technicians always identify which microphone has failed before recommending repairs.

Step 1: Restart Your Phone

A temporary software glitch is one of the easiest causes to eliminate. Restarting refreshes:

Audio drivers
Background services
Phone app
Voice processing
System cache

Many temporary microphone problems disappear after a simple restart. Although basic, this remains one of the first diagnostic steps our technicians perform.

Step 2: Test the Microphone Properly

Don’t rely only on phone calls. Instead, test multiple audio functions. Try:

Voice Recorder
WhatsApp Voice Notes
Camera Video Recording
Google Assistant
Siri
Zoom
Microsoft Teams
Voice Search

If Voice Recorder works but phone calls don’t, the issue is likely software-related rather than a damaged microphone. Testing multiple apps provides valuable clues before replacing any hardware.

Step 3: Check Microphone Permissions

Privacy settings may prevent apps from accessing your microphone. Review permissions for apps such as:

WhatsApp
Zoom
Teams
Messenger
Skype
Google Meet
Camera

On Android:

Settings → Privacy → Microphone Permission

On iPhone:

Settings → Privacy & Security → Microphone

If permission is disabled, the app cannot record your voice even if the microphone is fully functional.

Step 4: Clean the Microphone Openings

One of the most overlooked causes of poor microphone quality is dirt. Microphone holes easily collect:

Pocket lint
Dust
Makeup
Skin oils
Dirt
Fabric fibres

These tiny openings are extremely sensitive. Clean carefully using:

Soft anti-static brush
Microfibre cloth
Compressed air

Never use:

Pins
Needles
Toothpicks
Safety pins
Metal wire

These objects can permanently damage the microphone membrane. If your phone has also started producing distorted audio or you cannot hear callers properly, the problem may involve both the microphone and speaker system. In that case, read our How to Fix Phone Speaker Issues for a complete diagnosis.

Step 5: Disconnect Bluetooth Devices

Many users forget their phone remains connected to:

Wireless earbuds
Bluetooth headphones
Smart watches
Car audio systems
Portable speakers

If Bluetooth audio is active, your phone may be using another microphone instead of the built-in one. Try:

Disable Bluetooth.
Disconnect all paired devices.
Test your microphone again.

This simple step resolves many “microphone not working” complaints.

Step 6: Remove the Phone Case

Some rugged phone cases partially cover the microphone openings. This can cause:

Muffled audio
Quiet recordings
Distorted voice
Poor call quality

Remove the case temporarily and repeat the microphone tests.

Step 7: Install the Latest Software Updates

Operating system updates frequently include fixes for:

Audio drivers
Call quality
Voice processing
App compatibility
Security improvements

Check for updates.

iPhone

Settings → General → Software Update

Android

Settings → Software Update

Install official manufacturer updates only.

Step 8: Boot Into Safe Mode (Android)

Third-party applications occasionally interfere with microphone functionality. Safe Mode loads only essential system apps. If the microphone works normally in Safe Mode:

A recently installed app is likely responsible.
Remove suspicious apps.
Restart normally.
Test again.

Safe Mode is particularly useful after installing recording apps or call-recording software.

Step 9: Reset App Preferences or Network Settings

Corrupted settings may affect voice communication. Depending on your device, consider:

Reset Network Settings
Reset App Preferences
Reset All Settings

These options restore system configurations without immediately erasing personal files. A full factory reset should only be considered after backing up your important data and exhausting less invasive troubleshooting steps.

How to Fix a Phone Microphone After Water Damage?

Water damage is one of the most serious causes of microphone failure. Even a small amount of moisture can affect the delicate microphone membranes, audio circuits, and connectors inside your smartphone. While some devices have water-resistant ratings, no phone is completely waterproof, and prolonged exposure to liquids can still cause internal damage.

If your microphone stopped working after dropping your phone in water, spilling a drink on it, or getting caught in heavy rain, acting quickly can significantly improve the chances of a successful repair.

1. Turn Off Your Phone Immediately

If your phone is still switched on after water exposure, power it off as soon as possible. Continuing to use a wet phone can cause short circuits that damage the motherboard, charging IC, microphones, speakers, cameras, and display components. Remove the following if possible:

SIM card
Memory card
Protective case
External accessories

Leave the device switched off until it has been properly inspected or dried.

2. Dry the Outside Carefully

Use a clean, lint-free microfibre cloth to gently dry the exterior of the device. Pay particular attention to:

Bottom microphone holes
Charging port
Speaker grilles
SIM tray
Camera openings

Avoid shaking the phone, as this may push water deeper into the internal components.

3. Avoid Common DIY Mistakes

Many online “solutions” can actually make water damage worse.

Never:

Use a hairdryer.
Place the phone in an oven.
Leave it on a radiator.
Put it in direct sunlight for long periods.
Insert cotton buds or sharp objects into the microphone.
Charge the phone immediately.
Blow into the microphone holes.

One of the biggest myths is putting a wet phone in rice. For a complete step-by-step recovery process, read our Water Damaged Phone Repair guide, where our technicians explain what actually works and what should always be avoided.

4. Test the Microphone After Drying

Once the phone has dried naturally, test every microphone individually.

Check:

Phone calls
Speakerphone calls
Voice Recorder
Camera video recording
WhatsApp voice notes
Siri or Google Assistant

Sometimes only one microphone fails while the others continue working normally. Testing each function separately helps identify which microphone may be damaged.

5. Watch for Signs of Internal Corrosion

Even if the microphone starts working again, corrosion may continue developing inside the phone over the following days or weeks. Warning signs include:

Crackling audio
Muffled recordings
Random microphone failure
Speaker distortion
Charging problems
Camera issues
Unexpected shutdowns

Corrosion spreads gradually, which is why early professional cleaning often prevents much more expensive repairs later.

How to Fix a Phone Microphone After a Drop?

Dropping your smartphone can damage much more than the display. The impact may loosen internal connectors, damage the microphone module, or even affect the motherboard. If your microphone stopped working immediately after your phone was dropped, the problem is likely hardware-related.

1. Inspect the Device Carefully

Look for signs such as:

Cracked screen
Bent frame
Loose back glass
Damaged charging port
Cracked camera lens
Visible dents around the microphone area

Physical damage around the bottom edge of the phone often indicates impact near the primary microphone.

2. Test Different Recording Modes

Record audio using:

Front camera
Rear camera
Voice Recorder
Phone calls
Speakerphone

If only one function fails, technicians can identify which microphone requires replacement without replacing unnecessary components.

3. Check for Loose Internal Connections

Inside modern smartphones, microphones connect to the motherboard using delicate flex cables. A heavy drop may cause:

Loose connectors
Torn flex cables
Damaged microphone modules
Cracked solder joints
Motherboard faults

These issues require professional inspection because opening modern smartphones without specialist tools can damage waterproof seals, display cables, and Face ID or fingerprint components.

Signs Your Phone Needs Professional Microphone Repair

While many software-related microphone issues can be resolved at home, certain symptoms almost always require professional attention. Arrange a diagnostic if:

Nobody can hear you during calls.
Voice recordings contain no sound.
Audio cuts in and out constantly.
The microphone stopped working after water damage.
The problem began immediately after dropping the phone.
Cleaning the microphone made no difference.
Software updates have not resolved the issue.
Voice Assistant cannot detect your speech.
Multiple microphones have stopped working.
Other hardware problems have appeared alongside the microphone fault.

At iExpert Repairs, every device undergoes a comprehensive diagnostic before any repair is recommended. Our technicians identify the exact cause of the fault, ensuring only the necessary components are repaired or replaced. This approach helps avoid unnecessary costs while restoring your smartphone to full working order.

How Professional Technicians Diagnose Phone Microphone Problems

One of the biggest mistakes people make is assuming the microphone itself has failed. In reality, a microphone issue can originate from several different components, including the charging port assembly, audio IC, flex cables, motherboard, software, or even a blocked microphone mesh.

At iExpert Repairs, our certified technicians follow a structured diagnostic process before recommending any repair. This ensures that only the faulty component is repaired, saving customers unnecessary costs while restoring the device to full working order.

Step 1: Visual Inspection

Every repair begins with a careful external inspection. Technicians check for:

Impact damage
Bent frames
Cracked housings
Water indicators
Corrosion
Damaged microphone mesh
Loose charging ports
Previous repair work

Many microphone issues become obvious before the device is even opened.

Step 2: Software Diagnostics

Professional diagnostic software helps determine whether the microphone hardware is communicating correctly with the operating system. Technicians inspect:

Audio drivers
Microphone permissions
System logs
Error reports
Firmware version
App conflicts
Operating system integrity

Many intermittent microphone faults are resolved through software optimisation rather than hardware replacement.

Step 3: Audio Function Testing

Rather than relying on a single voice recording, technicians test every microphone individually. Typical tests include:

Standard phone calls
Speakerphone calls
Voice Recorder
Video recording
Noise cancellation
Voice Assistant
Third-party communication apps

Testing multiple audio functions helps identify exactly which microphone has failed.

Step 4: Internal Hardware Inspection

If software checks don’t identify the fault, the phone is carefully disassembled using specialist tools. Technicians inspect:

Microphone flex cables
Charging port assembly
Audio IC connections
Internal connectors
Moisture indicators
Corrosion
Motherboard damage

Because modern smartphones are tightly sealed with adhesive and waterproof gaskets, opening them without proper equipment can cause additional damage. This is why hardware inspections should always be carried out by experienced repair professionals.

How to Prevent Phone Microphone Problems?

While not every microphone fault can be avoided, good maintenance habits can significantly reduce the risk of expensive repairs. At iExpert Repairs, we’ve found that many microphone issues are caused by everyday wear, accidental damage, or poor charging and cleaning practices rather than manufacturing defects.

Following these simple tips can help keep your phone’s microphones working properly for years.

1. Keep the Microphone Openings Clean

Your smartphone’s microphone holes are exposed to dust, pocket lint, and other debris every day. Over time, this buildup can muffle your voice or reduce recording quality.

To keep them clean:

Wipe your phone regularly with a soft microfibre cloth.
Use a soft anti-static brush to remove dust.
Store your phone in a clean pocket or bag.
Avoid placing the phone on dirty surfaces.

Never insert needles, pins, or other sharp objects into the microphone openings, as this can permanently damage the sensitive microphone membrane.

2. Protect Your Phone from Drops

Accidental drops remain one of the leading causes of microphone failure. Even if the screen doesn’t crack, the impact can damage internal microphone components, flex cables, or the motherboard. Reduce the risk by:

Using a high-quality protective case.
Installing a tempered glass screen protector.
Avoiding carrying your phone loosely with keys or coins.
Keeping a secure grip when using your phone outdoors.

If your phone has recently been dropped and you’re experiencing multiple problems such as display damage or touch issues alongside microphone failure, our Phone Touch Screen Not Responding? explains how impact damage can affect several components at once.

3. Avoid Water and Excess Moisture

Although many modern smartphones offer some level of water resistance, no device is completely immune to liquid damage.

To reduce the risk:

Keep your phone away from swimming pools and sinks.
Avoid using it in heavy rain whenever possible.
Never charge a wet phone.
Dry the device immediately if it becomes damp.

If liquid has already entered your phone, follow the advice in our Water Damaged Phone Repair guide before attempting to use or charge the device again.

4. Use High-Quality Accessories

Poor-quality accessories can sometimes contribute to hardware problems over time. Whenever possible, use:

Manufacturer-approved chargers.
Certified USB cables.
Reliable power adapters.
Quality protective cases.

Cheap accessories may cause charging instability, electrical fluctuations, or overheating that can affect other internal components.

5. Keep Your Software Updated

Manufacturers regularly release software updates that improve:

Audio processing
Call quality
Security
System stability
App compatibility
Performance

Installing official updates helps prevent software bugs that may interfere with microphone functionality. Avoid downloading unofficial firmware or software from untrusted sources, as these can introduce compatibility issues and compromise device security.

When Should You Replace Your Phone Instead of Repairing It?

Not every microphone fault means it’s time to buy a new smartphone. In many cases, repairing the device is far more affordable than replacing it, particularly if the problem is limited to the microphone or another single component. Repairing your phone is usually the best option when:

Only the microphone has failed.
The device is otherwise in good condition.
The repair cost is significantly lower than buying a replacement.
The phone still receives software updates.
You want to keep your existing data and apps.

However, replacing the device may be the more practical choice if:

The motherboard has severe liquid damage.
Multiple expensive components have failed.
Repair costs approach the value of the phone.
The device is very old and no longer supported by the manufacturer.
