If your phone speaker is not working, sounds muffled, crackles, or is suddenly too quiet, the cause is usually one of three things: a setting, a software glitch, or something physically blocking the speaker grille, most often water or lint. Real hardware failure is less common than it feels in the moment, so the smart way to fix a phone speaker is to work from the cheapest, fastest checks toward the more involved ones.

This guide is a diagnostic ladder. Start at fix 1 and stop as soon as the sound is back. Each step either solves the problem or rules out a cause, so by the end you will know whether you need a cleaning cycle or a repair shop. It works for iPhone, Samsung Galaxy, Google Pixel, and other Android phones.

Quick Diagnosis: Match the Symptom to the Fix

  • No sound at all: start with fixes 1 and 2 (volume, silent mode, Bluetooth routing), then 3 and 4.
  • Muffled or "underwater" sound: jump to fixes 6 to 8 (clean the grille, eject water, test again).
  • Crackling or buzzing: if it started after water, try fixes 7 and 8. If it happens at every volume, read the hardware section.
  • Too quiet: check fix 1 (media volume, volume limits), then fix 6 for lint and dust.
  • Sound only fails in one app: fix 9 (app settings and safe mode).

Fix 1: Check Silent Mode, Do Not Disturb, and Media Volume

Phones keep separate volume levels for ringtones, notifications, calls, and media. Turning up the ringer does not turn up a video, and the reverse is also true. Open something that plays audio, then press the volume-up button while it plays so you are adjusting media volume.

  • iPhone: check the Ring/Silent switch or, on models with an Action button, the silent mode indicator. Silent mode mutes ringtones and alerts, while most media still plays.
  • Samsung and Android: pull down Quick Settings and make sure sound mode is not set to Mute or Vibrate, and that Do Not Disturb is off.
  • Volume limits: both iPhone and many Android phones can cap headphone or media volume. If the speaker is only quiet, look for a volume limiter in sound settings.

Fix 2: Check Bluetooth and Audio Routing

A very common "broken speaker" is really audio going somewhere else: earbuds in a case, a car stereo, a smartwatch, or a Bluetooth speaker in another room. Turn Bluetooth off for a moment and play audio again.

  • iPhone: open Control Center, long-press the audio card, and tap the AirPlay icon to see where sound is going. Choose iPhone.
  • Android: use the media output switcher in the notification shade or Quick Settings and select the phone speaker.
  • Samsung: also check whether Separate app sound is turned on in sound settings, which can send one app's audio to a different device.

Fix 3: Restart the Phone

A crashed audio service or a stuck app can silence the speaker until the system restarts. Power the phone fully off, wait about 30 seconds, and turn it back on. This takes a minute and clears a surprising number of sound problems, especially ones that appeared suddenly with no water or drop involved.

Fix 4: Update the Software

Audio bugs do occasionally ship in system updates and get fixed in the next one. Check for an update in Settings (General > Software Update on iPhone, Software update or System update on Android) and update the apps where the sound fails. If the problem started right after an update, a follow-up patch is often the real fix.

Fix 5: Test the Speaker So You Know What You Are Fixing

Before cleaning anything, figure out which speaker is affected and how. Most phones have a bottom speaker and an earpiece speaker at the top that also plays media in stereo. Play a song or video you know well with the case removed and listen to each end of the phone.

  • One end clear, one end dull: something is blocking that specific grille. Go to fixes 6 and 7.
  • Bass sounds rattly or distorted: water or debris is likely, but keep an eye out for hardware damage.
  • Calls are fine but media is silent (or the reverse): this points back to settings or routing, not the speaker itself.
  • Speaker works in a voice memo playback but not in one app: the app is the problem. See fix 9.

Fix 6: Clean the Speaker Grille Gently

Pocket lint, dust, and skin oil build up in speaker holes over months and slowly make a phone sound quieter. Cleaning the grille is safe if you stay gentle:

  • Use a soft, dry brush: a clean soft toothbrush or a small anti-static brush. Brush across the holes, with the grille facing down so debris falls out.
  • Lift stubborn lint carefully: a small piece of low-tack tape pressed lightly on the grille can pull loose dust out.
  • Do not use pins, toothpicks, or needles: they can puncture the speaker mesh or push debris deeper.
  • Do not blast compressed air up close: it can force dust and moisture further inside or damage the mesh.
  • Avoid liquids: do not pour cleaner or alcohol into the speaker holes.

Fix 7: Eject Water From the Speaker With WaterEject

If the phone got wet from rain, a sink, a shower, or a pool, water held in the speaker grille by surface tension is the most likely reason the sound is muffled or crackly. A low-frequency tone makes the speaker diaphragm move with larger strokes, which helps push those droplets out. WaterEject plays a calibrated tone in the low range (around 165 Hz) for exactly this.

  1. Unplug the charger. Do not charge a phone that may still be wet.
  2. Remove the case and wipe the phone dry with a lint-free cloth.
  3. Open the WaterEject tool in your phone's browser, or install the app.
  4. Hold the phone with the speaker facing down so gravity helps the water leave.
  5. Turn media volume to maximum, and lower it slightly if the tone sounds harsh or distorted.
  6. Run one cleaning cycle, then rest the phone for a minute.
  7. Repeat for two or three cycles in total if the sound is getting clearer.

Want just the tone? The water eject sound page plays it directly. For a full walkthrough by phone model, see the water ejection guide, and if the phone has only just come out of the water, follow the emergency water removal guide first. The physics are explained in how sound removes water from speakers.

Fix 8: Run the Speaker Test After Cleaning, and Repeat if Needed

Cleaning only counts if the sound actually comes back. When a WaterEject cycle finishes, the tool now plays a short test sound covering low, mid, and high tones and asks how it sounds. Listen closely: a healthy speaker sounds crisp, not muffled or crackly.

  • Clear now: you are done. Let the phone sit for a while anyway if it was soaked, since water inside the body dries more slowly than the grille.
  • Still muffled: run another cycle with the speaker facing down. Stubborn water or dust often needs two or three passes.
  • No better after three or four cycles: stop. More cycles will not help, and the cause is probably something sound cannot fix. Move on to fix 9 and the hardware section below.

Fix 9: Rule Out Apps With Safe Mode or a Settings Reset

If sound works in some places but not others, an app or a changed setting may be interfering. On Android, safe mode starts the phone with downloaded apps disabled: press and hold the power button, then press and hold Power off until the Safe mode option appears. If the speaker works normally in safe mode, a recently installed app is the likely cause. Restart to leave safe mode.

iPhone has no user-facing safe mode, but Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings returns system settings to defaults without deleting your photos or apps. Use it as a last software step before considering a repair.

How to Get Water Out of a Samsung Phone Speaker

Galaxy phones use the same physics as any other phone, but a few Samsung-specific details help:

  • Find both speakers: most Galaxy phones have a bottom speaker next to the USB-C port and an earpiece speaker that also plays media. Run a cycle facing each end down if both sound dull.
  • Moisture detected warning: that alert is about the charging port, not the speaker. Do not charge until it clears, and do not try to dry the port with heat.
  • Dolby Atmos and Equalizer: in Settings > Sounds and vibration > Sound quality and effects, try switching Dolby Atmos and any equalizer preset off and on again. An unusual EQ can make a healthy speaker sound thin or muffled.
  • Separate app sound: in the same sound settings, make sure it is not sending media to another device.
  • Safe mode test: if only certain apps are silent, use safe mode as described in fix 9.

For Google Pixel and other Android phones, the sound settings live under Settings > Sound & vibration, and the water ejection steps are identical. The WaterEject Android page covers Android-specific tips.

iPhone Speaker Not Working: iPhone-Specific Checks

  • Settings > Sounds & Haptics: drag the ringer and alerts slider. If you hear nothing at all from this slider, the speaker or its connection may need service.
  • Balance: in Settings > Accessibility > Audio & Visual, check that the left/right balance slider is centered. An off-center balance makes one speaker quieter.
  • Accessories: remove MagSafe wallets, thick cases, and screen protectors that overlap the earpiece, then test again.
  • After water: point the bottom speaker down and run a water eject cycle. Water resistance ratings do not keep water out of the speaker grille, as explained in phone water resistance myths.

If your AirPods or earbuds are the ones that sound muffled, see the separate AirPods water damage guide.

Signs Your Phone Speaker Needs a Repair

Sound-based cleaning and settings fixes cannot repair a damaged part. Book a repair if you notice any of these:

  • Crackling or buzzing at every volume level, even with a clean, dry grille and days after any water exposure.
  • No sound at all after you have checked settings and Bluetooth, restarted, and let the phone dry.
  • Rattling after a drop, which suggests a loose or broken component.
  • Visible damage: a torn or dented mesh, corrosion, or discoloration around the speaker holes.
  • Saltwater, soda, or dirty water exposure, where corrosion risk is higher and professional cleaning may be needed.
  • Sound gets worse with each cleaning cycle. Stop and let the phone dry naturally.

Frequently Asked Questions

Why is my phone speaker not working?

Most often it is media volume, silent or Do Not Disturb mode, or audio routed to a Bluetooth device. Next come software glitches, then water or debris in the grille, and finally hardware failure. Check them in that order.

How do I fix a muffled phone speaker?

Remove the case, brush the grille gently with a soft dry brush, then run a low-frequency water eject cycle with the speaker facing down at high volume. Test the sound and repeat two or three cycles if it is improving.

How do I fix a crackling phone speaker?

Crackling that started after water usually clears once the water is out and the phone has dried. Crackling at every volume, days later, with a clean grille, points to a damaged speaker that needs repair.

How do I get water out of my Samsung phone speaker?

Stop charging, remove the case, wipe the phone, and hold the bottom speaker facing down. Set media volume to maximum, run a WaterEject cycle, test the sound, and repeat if it is still muffled. Rotate the phone to clear the earpiece speaker too.

When should I take my phone speaker to a repair shop?

When there is no sound after the settings checks and drying, the speaker crackles or buzzes at every volume, it rattles after a drop, you see visible damage or corrosion, or the phone was in saltwater or other liquids.

Speaker muffled after water? Open the WaterEject tool, point the speaker down, run a cycle, and use the built-in test sound to check the result. Or install the app for more cleaning modes.
