How to Fix Xiaomi Phone Microphone Not Working During Calls
Fix xiaomi microphone not working and redmi mic issue. Solve poco mic fix for xiaomi call microphone with hyperos mic permission.
If the person you're calling can't hear you, the microphone on your Xiaomi, Redmi, or POCO phone may be blocked, muted, or restricted. Here's how to troubleshoot it.
Step 1: Check If Microphone Permission Is Granted
Go to Settings > Privacy > Permission Manager > Microphone. Ensure the Phone app, WhatsApp, Zoom, or whichever app you're using has microphone permission set to "Allow".
Step 2: Check for Physical Blockage
The primary microphone is at the bottom of the phone (near the USB-C port). Check if:
- A thick phone case is covering the mic hole
- There's dust, lint, or debris in the mic grille
- A screen protector has been applied over the mic area
Use a dry toothpick or brush to gently clean the opening.
Step 3: Test With Another App
Open the Voice Recorder app (built into HyperOS) and make a test recording. If your voice is recorded clearly, the hardware works fine and the issue is app-specific (e.g., a permission or app bug).
Step 4: Disable Noise Cancellation Temporarily
Settings → Sound → Noise Cancellation (or Microphone Enhancement) → toggle off. Occasionally this feature causes mic detection issues.
Step 5: Run the Microphone Hardware Test
Dial *#*#64663#*#* → Mic in the hardware test menu. This outputs a live mic recording so you can hear whether the hardware works.
Step 6: Restart and Update
Restart the phone and check for HyperOS updates. Microphone bugs have been patched in several firmware releases.
Step 7: Factory Reset / Service Center
If the hardware test confirms no mic input, the microphone component needs replacement at a Xiaomi service center.
