The bottom speaker clogs with pocket lint. Clean with the Lightning/USB-C edge down. Do not poke the grille with a pin.
Play a speaker dust cleaning sound that vibrates the driver to help clear speakers clogged with lint. It may loosen dust in the grille — it will not fix water damage or replace a repair.

Sound may loosen lint or dust in the grille. It will not repair liquid corrosion or a damaged driver.
How does it sound now?
A speaker dust cleaning sound moves the speaker diaphragm at several frequencies so loose lint and dust in the grille may fall out. Run one or two cycles with the grille facing down, then brush the mesh with a soft, dry brush. It cannot clear packed lint or dust that has reached the driver, and it is not for water — use Water Eject.
A speaker is a moving diaphragm. A sustained tone or a short frequency cycle makes that diaphragm travel back and forth. Loose lint, dust, or sand sitting in the grille may shift. That is the entire mechanism — not a solvent, not a vacuum, and not a repair shop.
The safe order is: one cleaning cycle, then a soft dry brush, then compare. If the mesh is packed hard, a soft dry brush plus one cleaning cycle usually beats ten minutes of maximum volume.
If the phone was wet, switch to Water Eject instead of looping cleaner modes. Not sure which applies? Fix My Speaker runs both.
Most muffled speakers are just dry lint in the bottom grille. This routine handles them without tools that can tear the mesh:
A sound cleaner cannot reach dust that has worked past the mesh onto the driver. If two rounds change nothing, more volume will not either.
The earpiece you hear calls through has its own small grille at the top of the phone, and it clogs with skin oil and lint. Many phones also play media through it, so the dust cleaning sound can reach it: hold the top edge down and keep the volume low. Finish with a soft brush — never a pin. For muffled calls specifically, use Ear Speaker Cleaner.
The bottom speaker clogs with pocket lint. Clean with the Lightning/USB-C edge down. Do not poke the grille with a pin.
Some models have a top and bottom speaker. Run the tone, then rotate so each grille faces down once.
Keyboard crumbs often sit above downward-firing speakers. Invert the machine briefly after a cycle if the vents are exposed.
Fabric grilles trap sand. The tone may help; a soft dry brush usually does more.
Repeat once with the grille facing down. Soft-brush the holes. If the phone was in water, switch to Water Eject rather than looping this tone.
Stop. Do not keep raising volume. Let the device dry, then re-test. Persistent crackle can mean a damaged driver.
A fall can tear the driver or loosen a connector. Tones will not reseat hardware. Use Speaker Test to document the fault, then seek repair.
Fix My Speaker runs a water eject tone and a dust cleaning sound back to back, then points you to the next step.
A sequence of tones that makes the speaker diaphragm move at several speeds. With the grille facing down, that movement may shake loose dust and lint sitting in the mesh.
Run one or two dust cleaning cycles with the grille facing down, then brush the holes with a soft dry brush. If the phone was wet, use Water Eject instead.
Take the case off, point the grille at the floor, set the volume to about half and press Play on the dust cleaning sound. When it ends, brush the grille lightly and compare. That is the whole routine — repeat once at most.
Use a clean, dry, soft-bristled brush (a new toothbrush works), brushing across the holes rather than into them. Do not use pins, toothpicks, compressed air or liquid cleaners — they push debris deeper or tear the mesh.
Often, yes. Many phones play media through the earpiece too. Hold the top grille down, play the dust cleaning sound at low volume, and avoid pushing anything into the mesh.
Vibration can help loosen dry lint or dust sitting on the grille. It may do nothing for liquid corrosion, torn drivers, or software volume limits.
No. Speaker Cleaner targets debris with mixed frequencies. Water Eject uses a sustained low tone aimed at moisture near the port. Use both only if both problems apply.
One or two passes. The recommended dust cleaning sound runs 26 seconds, Steady 220 Hz 30 seconds and Low 130 Hz 20 seconds. If two passes changed nothing, longer sessions will not either.
Yes. Keep the volume moderate and do not press the speaker into a pillow. The tone only moves the driver that is actually playing.
