iPhone Microphone Not Working During Calls: Causes & Solutions
Is your iPhone microphone not working during phone calls? Can you hear the other person clearly, but they cannot hear your voice? Or does your voice sound muffled, distorted, or unusually quiet during conversations?
Microphone problems are frustrating, especially when you depend on your iPhone for business calls, WhatsApp conversations, video meetings, and everyday communication.
An iPhone microphone problem can result from blocked microphone openings, incorrect settings, Bluetooth accessories, software issues, liquid damage, or internal hardware faults.
If you're searching for iPhone microphone repair in Dhaka, Mobile Fixer Ltd provides smartphone diagnostic and repair services to help identify microphone-related problems and recommend suitable solutions.
In this guide, we'll explain the common causes of iPhone microphone failure, practical troubleshooting methods, microphone testing procedures, repair costs in Bangladesh, and when professional servicing may be necessary.
1. Why Is My iPhone Microphone Not Working During Calls?
Several issues can prevent your voice from reaching the other person during a phone call.
Common causes include:
Dust or debris blocking microphone openings
Phone cases or screen protectors obstructing microphones
Bluetooth audio routing problems
Temporary iOS software glitches
Microphone permission restrictions in applications
Damaged microphone components
Liquid exposure
Internal connector damage
Audio circuit or motherboard faults
Cellular or internet connection problems
Not every microphone issue requires hardware replacement.
The first step is to determine whether the problem affects regular calls, speakerphone calls, video recordings, or all audio recording functions.
2. Common iPhone Microphone Problems
iPhone Caller Can't Hear Me
One of the most common complaints is that the other person cannot hear your voice during a phone call.
You may hear the caller clearly while your microphone transmits little or no audio.
Possible causes include microphone obstruction, incorrect audio routing, hardware failure, or a network-related issue.
iPhone Microphone Sound Is Too Low
Sometimes the microphone works, but the other person can barely hear you.
Common symptoms include:
Very quiet voice during calls
Muffled speech
Inconsistent microphone volume
Voice becoming unclear during conversations
A blocked microphone opening or damaged microphone component may contribute to these symptoms.
iPhone Microphone Not Working on Speakerphone
If your microphone works during regular calls but fails when using speakerphone, the issue may involve a different microphone, audio processing, or software behavior.
Modern iPhones use multiple microphones for different recording and communication functions.
Testing several audio modes can help narrow down the problem.
iPhone Microphone Not Working on WhatsApp or Messenger
If regular cellular calls work but WhatsApp, Messenger, or another application cannot record your voice, the problem may involve application permissions or software settings.
Check:
Settings > Privacy & Security > Microphone
Make sure the affected application has microphone access.
Also update the application and test another calling service.
iPhone Microphone Not Working After Water Damage
Liquid exposure can affect microphone components and internal circuitry.
Symptoms may include:
Muffled voice recordings
Intermittent microphone operation
Crackling audio
Complete microphone failure
Problems affecting multiple audio functions
If your iPhone has been exposed to liquid, avoid charging it until it is safe to do so.
Do not use excessive heat, compressed air, or sharp objects to dry or clean microphone openings.
3. Understanding iPhone Microphone Locations
Most modern iPhones contain multiple microphones positioned in different areas of the device.
Their exact locations and functions vary by model.
Microphone Area | Common Function |
|---|---|
Lower microphone area | Voice capture during regular calls and recordings |
Front microphone area | Front-facing video and communication |
Rear microphone area | Rear-camera video and audio capture |
Some audio functions use multiple microphones together for noise reduction and directional recording.
A microphone test should consider the device model and the application being used.
4. How to Test Your iPhone Microphone
Before requesting repair, test whether the microphone works in different applications.
Test 1: Use Voice Memos
Open the Voice Memos application.
Tap the Record button.
Speak clearly near the lower microphone area.
Stop recording.
Play the recording.
If your voice sounds clear, at least part of the microphone system is functioning.
If the recording is silent, distorted, or unusually quiet, further troubleshooting may be necessary.
Test 2: Record a Front Camera Video
Open the Camera application.
Switch to the front-facing camera.
Record a short video while speaking.
Play the video and listen to the audio.
Check whether your voice sounds normal.
Test 3: Record a Rear Camera Video
Switch to the rear camera and record another short video.
Compare the audio quality with the front-camera recording.
Test 4: Make a Regular Phone Call
Call someone you trust and ask whether they can hear you clearly.
Test 5: Try Speakerphone
During the call, switch to speakerphone.
Check whether the microphone works differently.
Important: These tests can help identify patterns, but they cannot conclusively determine which internal microphone is damaged. iOS may use different microphones and processing methods depending on the model and application.
5. How to Fix iPhone Microphone Not Working
Try the following troubleshooting methods before considering hardware repair.
Step 1: Restart Your iPhone
Restarting can resolve temporary software issues that affect microphone functionality.
Turn off the device, wait briefly, and turn it back on.
Step 2: Remove Your Phone Case
Some cases, screen protectors, or accessories may partially cover microphone openings.
Remove the case and test your microphone again.
Step 3: Inspect Microphone Openings
Check whether dirt or debris is blocking the microphone openings.
If necessary, gently clean accessible openings using a clean, dry, soft-bristled brush.
Avoid inserting sharp objects or pushing debris into the device.
Step 4: Disconnect Bluetooth Accessories
Your iPhone may be using the microphone on connected wireless headphones or another accessory.
Open Settings > Bluetooth and temporarily disconnect connected audio devices.
Test the built-in microphone again.
Step 5: Check Microphone Permissions
If the problem occurs only in a particular application, open:
Settings > Privacy & Security > Microphone
Check whether the application has permission to use the microphone.
Step 6: Check for iOS Updates
Open:
Settings > General > Software Update
Install a compatible update if available.
Software updates may resolve certain application or system-related audio problems.
Step 7: Test Different Applications
Compare microphone performance using:
Voice Memos
Regular phone calls
WhatsApp calls
Messenger calls
Front-camera video
Rear-camera video
If the microphone fails only in one application, troubleshoot that application before assuming hardware damage.
Step 8: Check Your Network Connection
If your voice breaks up only during cellular or internet calls, poor network quality may be contributing to the problem.
Try calling from an area with a stronger signal or using a stable internet connection.
Step 9: Seek Professional Diagnosis
If your microphone remains silent, distorted, or unreliable across multiple applications, professional hardware inspection may be necessary.
6. Why Does My iPhone Microphone Work on Speakerphone but Not Regular Calls?
Different calling modes may use different microphones or audio processing configurations.
If your microphone works on speakerphone but not during regular calls, possible causes include:
A microphone obstruction
A fault affecting a particular microphone
Audio routing problems
Noise processing issues
Software-related problems
Internal hardware damage
The opposite can also happen: regular calls work normally while speakerphone audio fails.
These symptoms are useful diagnostic clues, but the actual cause should be confirmed through testing.
7. iPhone Microphone Not Working After an iOS Update
Some users notice microphone problems after updating iOS.
Potential causes include:
Temporary software glitches
Application compatibility issues
Changed privacy permissions
Audio routing problems
An unrelated hardware fault
Try restarting your iPhone, checking microphone permissions, and updating affected applications.
If the problem persists across multiple applications, further diagnosis may be necessary.
8. Can an iPhone Microphone Be Repaired?
Yes. Some iPhone microphone problems can be resolved through troubleshooting, cleaning, or component-level repair.
The appropriate solution depends on the underlying fault.
When Cleaning or Troubleshooting May Help
Dust blocking microphone openings
Phone case obstruction
Incorrect audio routing
Application permission issues
Temporary software problems
When Microphone Replacement May Be Necessary
Physically damaged microphone
Failed microphone component
Internal connection damage
Confirmed hardware failure
When Motherboard Repair May Be Required
Some microphone failures are associated with audio-related circuits or motherboard faults.
These cases may require advanced diagnosis and, where technically appropriate, micro-soldering or circuit-level repair.
Not every audio circuit fault is repairable, and repair feasibility depends on the device model and extent of damage.

10. iPhone Microphone Repair vs Replacement
Microphone repair and replacement are not always the same procedure.
In some iPhone models, a microphone is integrated into a larger internal assembly.
Depending on the device, repairing a microphone-related problem may involve:
Cleaning an obstructed opening
Reconnecting an internal component
Replacing a compatible microphone assembly
Repairing damaged circuitry
Resolving a software or configuration issue
Some front-facing microphone and sensor assemblies are located near components associated with Face ID.
Repairs involving these areas require particular care because certain modifications may affect Face ID functionality.
A technician should explain the recommended procedure and any relevant risks before starting the repair.
