Start with “Record and play back your voice with the built-in recorder”
Do not assume the cause from the symptom alone. First determine whether the issue affects the whole phone, one app, one connection, or one accessory. Work from low-impact checks toward recovery or repair.
- Record and play back your voice with the built-in recorder
- Compare a normal call, speakerphone, front-camera video, and rear-camera video
- Remove any case or protector that may cover a microphone opening
The key boundary to diagnose first
Compare calls, recording, video, and speakerphone to identify the affected microphone path.
Do not insert sharp objects into microphone openings.
Escalate with device, OS, error, and reproduction details when the issue persists after restart, controlled comparison, and update checks, or when physical damage, abnormal heat, account suspension, or carrier provisioning is suspected.
Separate “Record and play back your voice with the built-in recorder” from “Compare a normal call, speakerphone, front-camera video, and rear-camera video”
| Scope of the issue | Where to check next |
|---|---|
| Only one app is affected | Check app permissions, updates, storage, cache, and reinstall options |
| The whole phone is affected | Check restart, system updates, free storage, and system settings |
| Other devices have the same issue | Check the network, service, charger, or accessory |
| The issue began after a drop or liquid exposure | Avoid repeated power or charging attempts and contact official support |
Diagnostic order for Phone Microphone Not Working or Others Cannot Hear You: Troublesh
Use the lowest-impact sequence first
Complete one step at a time and test after each change. Do not change several settings at once.
- 1Disconnect Bluetooth headsets and select the phone microphone as the input source.
- 2Open app permissions, confirm microphone access, toggle it off and on, and test again.
- 3Remove the case and inspect microphone openings for surface debris. Do not insert sharp tools.
- 4Compare the built-in recorder, front video, rear video, and calls to identify which microphone path fails.
- 5Restart and update the phone and app. If only calls fail, also check network quality and call-processing settings.
- 6If several built-in functions cannot record audio, verify your backup and request official diagnostics or repair.
Do not erase the evidence before isolating the cause
- Pushing needles or cotton swabs deep into microphone openings
- Repeatedly reinstalling an app before checking permissions
- Relying on the untested phone for an important call or meeting
Prevent the issue from returning
- Make a short test recording after fitting a new case
- Review microphone permissions after major system updates
