Source-checked About 10 minutes
Answer
Clean and uncover the microphones, test Voice Memos and Camera, allow microphone access for the app, then isolate software from hardware failure.
Remove physical obstructions
Remove the case or screen protector if it covers an opening and gently clear dry debris without liquid or sharp tools.
Run Apple's recording tests
Record in Voice Memos and both Camera orientations, then play the results to identify which microphone path fails.
Check app permission
Open Settings > Privacy & Security > Microphone and allow only the app that needs to record.
Update or seek service
Restart and update iOS; if Apple's tests remain silent or distorted, contact Apple for hardware service.
