Start with these three checks
- Turn off silent mode and Do Not Disturb.
- Disconnect Bluetooth devices.
- Restart the phone.
Then clean
Water and dust cause most muffled sound. Run a cleaning cycle and brush the grille gently.
Then test
Use the Tone Generator to play steady tones. If one specific tone rattles, something is loose. If all tones are distorted, the speaker is likely damaged.
Update your phone
Software bugs can cause audio problems. Install the latest system update and update the app you are using.
When to see a repair shop
- Crackling at low volume
- No sound after all checks
- Visible damage or corrosion near the grille
