You pick up a call, say hello, and the person on the other end hears nothing. Or worse, they can’t hear you clearly at all. If your iPhone’s mic not working during calls is driving you crazy, you are not alone. This is one of the most common issues iPhone users run into, and the good news is that it is often fixable without heading straight to a repair shop.
Let us walk through what is actually going on and how to solve it.
Why Is the iPhone Microphone Not Working?
Before you troubleshoot, it helps to understand what you are dealing with. iPhones actually have more than one microphone. The bottom microphone handles regular voice calls, the front microphone is used for FaceTime calls and selfie videos, and the rear microphone or back microphone, picks up audio when you record videos with the camera app.
If only one of them stops working, the issue might be physical, like dirt or damage, or it could be a software glitch causing the problem.
Quick Fixes to Try Right Now
Check for Debris Blocking the Mic
This one gets overlooked all the time. Lint, dust, and grime can muffle sound coming through the built-in microphone. Grab a clean, dry toothbrush or a cotton swab and gently clean around the microphone openings. Do not use liquid. You would be surprised how often this simple step is all it takes to resolve the issue.
Unplug Any Connected Accessories
If you have earbuds, a headset, or any Bluetooth device connected, your iPhone may be routing audio through that device instead. Unplug everything and toggle Bluetooth off, then try a normal phone call again.
Check App Permissions to Access the Microphone
Sometimes, the problem is not the microphone on iPhone itself – it is that an app simply does not have permissions to access it. Go to Settings, then Privacy and Security, then Microphone. Make sure the Phone app or the app you’re using has microphone access turned on.
Test With the Voice Memos App
Open the Voice Memos app and record a short clip. If the audio sounds clear, your built-in microphone is working, and the issue may be tied to a specific microphone setting inside a specific app or with voice calls only.
Run a Software Update
Outdated iOS versions can cause microphone issues. Apple regularly pushes iOS updates that fix known glitches. Go to Settings, General, then Software Update and install the latest iOS available. iOS 10 and earlier versions had documented audio bugs, and staying current helps avoid those.
Disable Noise Cancellation
Some iPhones, including models such as the iPhone 6, iPhone 11, and iPhone 12, have a noise cancellation feature that can sometimes cause problems. Go to Settings, Accessibility, Audio and Visual, and toggle it off.
Reset iPhone Settings
If nothing else works, try resetting your iPhone: go to Settings > General > Transfer or Reset iPhone, then choose Reset All Settings. This will not delete your data, but it can clear out software conflicts that diagnose the problem further.
When to Contact Apple Support or a Local Repair Shop
If you have gone through all the troubleshooting steps and the iPhone microphone is not working, you may be dealing with a hardware issue. A damaged IC component, water damage, or a physically broken microphone will not fix itself through settings.
