Crackling usually means something is touching or blocking the speaker cone, or that the speaker is damaged. Moisture and dust are the most common causes, and both are fixable.
Common causes
| Cause | Clue |
|---|---|
| Water in the grille | Started after getting wet |
| Dust or lint | Crackles mainly on bass |
| Audio file or app | Only one song or app crackles |
| Volume too high | Crackles only at max volume |
| Damaged speaker | Crackles at every volume |
Fixes to try
- Run Deep Clean mode once to clear water and dust together.
- Brush the grille gently with a soft, dry toothbrush.
- Play a different song or app to rule out a bad file.
- Lower the volume one or two steps and test again.
- Restart and update your phone.
Find the exact problem
Use the Tone Generator. Play 100 Hz, 440 Hz and 1 kHz. If only low tones crackle, the cone may be catching on debris or slightly damaged. If every tone crackles, the speaker likely needs replacing.
When it is hardware damage
Crackling that does not change after cleaning, drying and restarting usually means the speaker is worn or torn. A repair shop can replace it.
FAQ
Can water damage cause permanent crackling?
Yes, if minerals dry on the cone or the coil corrodes. That is why it helps to clear water quickly.
