A phone speaker that still works but sounds unusually quiet is usually easier to diagnose than a completely silent speaker.
The most useful question is:
Is everything quiet, or only one type of sound?
Check these separately:
- music or video;
- ringtone;
- notifications;
- calls at your ear;
- speakerphone.
That tells you whether the problem is the main speaker, the call receiver, a volume setting, audio routing, or one specific app.
First, Test the Right Volume
Phones use separate volume controls for different types of sound.
While music or a video is playing, press Volume Up.
For an active phone call, raise the volume while the other person is speaking.
For ringtone and notification volume, open the phone’s sound settings.
On Pixel, Google separates:
- media volume;
- call volume;
- ring volume;
- notification volume;
- alarm volume.
If calls sound normal but music is quiet, the media volume may simply be lower.
If music is loud but calls at your ear are quiet, focus on the call receiver rather than the main loudspeaker.
Remove the Case and Screen Protector
A case can partially cover a bottom speaker opening.
A poorly aligned screen protector can also interfere with the top receiver used during calls.
Remove both temporarily and test again.
If the volume improves immediately, the speaker itself is probably fine.
Replace the accessory rather than changing deeper phone settings.
Check the Speaker Openings for Dirt
Dust, pocket lint, and other debris can reduce speaker volume without stopping sound completely.
Inspect the speaker grille in good light.
Apple recommends checking the speaker and receiver openings for blockage and, when necessary, cleaning them with a clean, dry, soft-bristled brush.
Google also recommends gently cleaning Pixel speakers with a soft, lint-free cloth when sound is unclear or too quiet.
Do not use:
- pins;
- needles;
- metal tools;
- liquid cleaner;
- excessive force.
Pushing debris deeper can make the problem worse.
Compare Speakerphone With Normal Call Audio
Make a test call.
First listen with the phone at your ear.
Then turn on Speaker.
Speakerphone is loud but the call receiver is quiet
Focus on:
- the top receiver opening;
- screen protector alignment;
- call volume;
- receiver hardware.
Normal call audio is fine but Speaker mode is quiet
Focus on:
- the main speaker opening;
- Bluetooth routing;
- speaker settings;
- speaker hardware.
If your issue is specifically with iPhone calls, see iPhone Speaker Not Working During Calls.
Turn Bluetooth Off Temporarily
The phone may still be sending audio to another device.
Common examples include:
- earbuds;
- headphones;
- car audio;
- Bluetooth speakers;
- hearing devices.
Turn Bluetooth off and play audio again.
If the built-in speaker becomes normal, the problem was audio routing rather than the speaker itself.
Check Whether Only One App Is Quiet
Play sound from more than one source.
For example:
- play a video;
- play music;
- test a ringtone;
- test another app.
If only one app is quiet, check that app before changing the whole phone.
Possible causes include:
- an in-app volume control;
- equalizer settings;
- media normalization;
- app bugs;
- audio output selection.
Updating or restarting the affected app is more appropriate than resetting the phone.
Check Audio Balance and Accessibility Settings
An incorrect left/right audio balance can make one speaker sound weaker.
On Android, look under:
Settings > Accessibility
The exact path varies by manufacturer.
Look for audio options such as:
- left/right balance;
- mono audio;
- hearing enhancements.
Return unusual settings to their normal position and test again.
Do not disable accessibility features that you actively use unless you are only testing whether one setting is affecting the output.
Check Phone-Specific Sound Features
Some phones have audio features that change speaker output.
On supported Pixel phones, Adaptive Sound adjusts audio based on the surrounding environment.
Google currently places it under:
Settings > Sound & vibration > Adaptive Sound
It does not simply increase volume, but turning it off and testing can help determine whether sound processing is affecting what you hear.
Samsung and other manufacturers may offer features such as:
- Dolby Atmos;
- Adapt Sound;
- equalizer controls;
- sound effects.
If the speaker became quiet after changing one of these settings, return it to the previous or default configuration.
Check for Moisture
A wet speaker can sound:
- muffled;
- weak;
- crackly;
- distorted.
If the phone recently got wet, let it dry properly before judging the speaker.
Do not use heat or push objects into the grille.
For a phone that became quiet after water exposure, use How to Get Water Out of a Phone Speaker.
Persistent distortion after the phone has dried can indicate hardware damage.
Restart the Phone
Restart once after checking the obvious physical causes.
A temporary audio-service or routing problem can occasionally make the speaker quieter than normal.
After restarting, test:
- media;
- ringtone;
- speakerphone.
If one type remains quiet while the others are normal, continue troubleshooting that specific audio path.
Install Pending Software Updates
Check for system updates if the volume problem began recently.
Software updates can include fixes for:
- audio routing;
- Bluetooth behavior;
- modem-related call audio;
- speaker processing.
Do not assume an update is responsible just because the timing is similar.
Use the symptom pattern to confirm whether the issue affects all sound or only one function.
Do Not Use “Speaker Cleaner” Apps as a First Fix
Some apps play tones or vibrations and claim to clean or boost phone speakers.
They may help move small amounts of water in limited situations, but they do not remove packed dirt, repair damaged speakers, or safely bypass hardware limits.
Avoid apps that promise extreme volume increases.
Driving a small speaker beyond its intended level can increase distortion and may damage it.
Be Careful With Volume Booster Apps
Third-party volume boosters can make sound seem louder by increasing gain or applying aggressive equalization.
That can also produce:
- clipping;
- harsh sound;
- distortion;
- speaker strain.
Use the phone’s built-in sound controls first.
If the speaker used to be much louder at the same settings, find the cause rather than trying to overpower the problem with software.
When Safe Mode Is Worth Trying
Safe Mode is useful only when the problem began after installing an app that can affect audio.
Examples include:
- equalizers;
- sound boosters;
- automation apps;
- call-recording apps;
- audio-routing utilities.
If the volume returns to normal in Safe Mode, remove the recently installed audio-related apps one at a time.
If you need help leaving Safe Mode afterward, see Android Stuck in Safe Mode.
When the Speaker Probably Needs Repair
Hardware becomes more likely when:
- the speaker remains quiet across every app;
- cleaning makes no difference;
- both media and speakerphone are weak;
- the phone was dropped;
- the problem followed liquid exposure;
- sound is distorted even at moderate volume;
- the speaker buzzes or crackles;
- volume has steadily decreased despite normal settings.
Apple says that if the speaker still produces no usable sound after checking the opening and sound controls, service may be required.
Google also recommends further support when low or distorted audio continues after basic troubleshooting.
A factory reset should not be the first response to a physically muffled or damaged speaker.
Quiet Speaker vs Speaker Not Working
These are not exactly the same problem.
A quiet speaker still produces sound, but the output is weaker than expected.
A speaker that is not working may produce no sound at all.
If there is completely no audio from the built-in speaker, use Phone Speaker Not Working instead.
