Quick answer: For a silent speaker, check silent mode, volume, Bluetooth and do-not-disturb first, then clean the grille with a dry soft brush. For a mic that is not working, remove the cover and test the voice recorder. If problems stay, the speaker, mic or charging board needs repair.

Is it the speaker, the earpiece or the microphone?
Phones have different parts for different jobs, and mixing them up leads to wasted time.
- Loudspeaker (usually at the bottom): plays ringtones, music, videos and speakerphone calls.
- Earpiece (at the top): plays the caller’s voice when the phone is held to your ear.
- Microphones (one or more, usually at the bottom, sometimes top and rear): capture your voice, video audio and noise cancelling.
Work out which one has failed before taking action.
Problem 1: No sound from the speaker
Run through these in order:
- Check volume for media and ringtone separately.
- Disable silent or do-not-disturb mode.
- Disconnect Bluetooth. The phone may be sending sound to an earbud, a car or a watch.
- Unplug the headphone or cable. Some phones think a headset is connected when it isn’t, because of dirt in the port.
- Restart the phone.
- Test different sources: a ringtone, a video, a speaker test in settings or a call.
If you hear sound through earphones but not through the speaker, the loudspeaker or its connection is probably the issue.
Problem 2: Crackling, buzzing or very low sound
- Dust and pocket lint on the speaker grille muffles sound. Switch the phone off and brush the grille gently with a soft dry brush. Do not poke the mesh with a pin, because it tears.
- Max volume with bass-heavy audio can make a small speaker distort. Lower the volume and check again.
- Water exposure damages speaker cones and leaves a muffled, crackling voice. See our water damage first-aid post.
- A loose or damaged speaker needs to be replaced.
Problem 3: People can’t hear me, or I sound muffled
- Take off the cover and screen protector. A badly cut cover or a protector that covers the mic hole blocks sound.
- Record a voice note with the built-in voice recorder and play it back. If it’s silent or weak, the mic is blocked or failing.
- Test speakerphone. On many phones, a different mic is used. If speakerphone works but normal calls do not, one mic is faulty.
- Clean the mic hole gently. A wooden toothpick near the opening, not inside, is the safest option; never push hard.
- Check app permissions. If only one app (WhatsApp, a recorder or a game) has no mic input, give it microphone permission in settings.
- Test in safe mode to rule out a third-party app that grabs the mic.
- Disable noise suppression features briefly and re-test.
Problem 4: Earpiece too quiet during calls
Dust in the earpiece mesh and a poorly fitted screen protector are the usual suspects. Check that your protector has a clean cutout for the earpiece. If the voice is quiet only on calls but loud on speaker, the earpiece may need replacement.
When a repair is needed
| Observation | Likely repair |
|---|---|
| No sound from the loudspeaker anywhere, after settings check | Loudspeaker (buzzer/ringer) replacement |
| Caller can’t hear you, recorder is also silent | Microphone or charging/mic sub-board |
| Sound only through earphones | Loudspeaker or its connector |
| Sound disappears after a fall | Connector or speaker damaged |
| Muffled sound after water exposure | Cleaning and replacing damaged parts |
| Mic only fails when charging port is wiggled | Charging board or port, since on some phones the mic sits on the same board |
Not all phones are built the same way, so the technician decides after testing. Expect the shop to test with a call and recorder in front of you.
Quick things to avoid
- Pushing needles or pins into the grille or mic hole.
- Using compressed air at close range.
- Soaking a phone in alcohol or spraying cleaner into holes.
- Playing max volume bass for long hours on a small speaker.
