Daily Tech Tip 22: Pocket dust, makeup and debris can block external speaker and microphone meshes. Gentle surface cleaning may improve sound, but liquid or internal damage needs diagnosis.
Why this matters
The mesh protects delicate components. Pushing tools through it can puncture membranes or force debris deeper inside.
Safe steps to try
- Power the phone off and remove the case.
- Use a clean, soft, dry brush across the mesh rather than into it.
- Test calls, voice recordings, speakerphone and media separately.
- Disable Bluetooth to make sure sound is not routing to another device.
- Restart the phone and check microphone permissions for the affected app.
What to avoid
- Do not insert pins or toothpicks through the mesh.
- Do not spray liquid or compressed air directly into openings.
- Do not assume every call issue is the microphone; signal and app problems can sound similar.
When to stop and get help
Audio that failed after liquid exposure, impact or a recent repair should be inspected, especially if several microphones or speakers are affected.
Clean only the surface, test multiple audio functions and seek help when the fault follows damage or remains across apps.
