How to Clean Samsung Galaxy Speakers (S22 through S25)

Samsung Galaxy phones have two speakers: the earpiece at the top (which doubles as a stereo tweeter for media playback) and the bottom-firing main speaker. Both trap dust. On foldable models the hinge area adds a third debris collection point. Fortunately, Samsung gives you more cleaning tools out of the box than any other manufacturer.

This is how to use all of them properly, in order.

What's special about Galaxy cleaning

Three things make Samsung cleaning different from iPhone cleaning:

1. The built-in water-eject tool. Samsung Members app includes a Diagnostics section with a "Clean speaker" feature. It plays a 165Hz tone for 10 seconds. Surprisingly few users know it exists.
2. Two actual speakers, not just one with stereo processing. Both need cleaning, but they collect debris differently — the earpiece collects skin oil and face-side dust, while the main speaker collects pocket lint.
3. Foldable hinges change the geometry. On Z Flip and Z Fold, the speakers move relative to the hinge during opening and closing, which can shift debris around in ways that don't happen on slab phones.

Each of these affects the routine.

Using Samsung's built-in cleaner first

The water-eject routine in Samsung Members is the easiest starting point if your phone has been near water.

1. Open the Samsung Members app. (Pre-installed on most Galaxy phones; free download if missing.)
2. Tap Support → Diagnostics → Clean speaker.
3. Tap Start. The phone plays a tone for 10 seconds.

What this does: pushes water out of the speaker cavity using the same mechanism other water-eject tools use. What it doesn't do: clean dust, verify audio quality, or handle the earpiece cleaning.

Run it once after water exposure. If audio is still muffled, proceed to the full routine.

The full cleaning routine

For dust, run the built-in tool plus additional steps:

1. Brush the bottom speaker grille with a soft-bristle toothbrush, parallel to the grille slot. Catches surface lint.
2. Brush the earpiece slit along the top of the phone. Same technique, smaller brush.
3. Open the Samsung Members cleaner if you haven't already.
4. Play a 165Hz sustained tone from a cleaning website or app for 30 seconds at max volume, speaker-down.
5. Test with a voice memo. Samsung's recorder app is built-in and works well for this.

If audio is muffled only on the earpiece (calls sound bad but media sounds fine), focus on the top speaker — clean the slit carefully and play the cleaning tone while holding the phone with the earpiece facing down.

Galaxy S24 and S25 specifics

The S24 and S25 introduced a slightly different speaker assembly. Changes that matter:

• Tighter grille tolerances on S24 and S25 mean less dust gets in, but what does get in is harder to remove.
• The earpiece is slightly larger than older models to improve stereo separation, which means more surface area to accumulate skin oil.
• IP68 rating is unchanged but the water-eject pulse works marginally faster because of the tighter cavity.

Practical implications:

• Run cleaning tones slightly longer (45 seconds instead of 30) on S24 and S25 because debris is stickier.
• Clean the earpiece more frequently. Weekly for phones used heavily for calls.
• The water-eject can be shortened to two 10-second pulses rather than three.

Z Flip cleaning (Flip 4, 5, 6)

The Z Flip has the main speaker at the bottom of the bottom half, plus an earpiece at the top of the top half. Between them: the hinge.

Cleaning the speakers:

1. Open the phone fully.
2. Run the Samsung Members cleaner first.
3. Brush the bottom speaker with the phone open, grille-down.
4. Close the phone, open it again, and run a 165Hz cleaning tone for 30 seconds. The opening motion can redistribute debris that was sitting above the speaker.
5. Check the hinge gap for visible lint — use a soft brush, not a pin.

Z Flip phones are especially prone to pocket lint accumulating at the hinge gap and eventually working its way to the speakers. A monthly hinge brushing prevents most of this.

Z Fold cleaning (Fold 4, 5, 6)

The Z Fold has stereo speakers split between the cover display edge and the unfolded inner display edge. Different cleaning depending on orientation:

1. Unfold the phone fully for the cleaning routine.
2. Hold it in landscape with both speakers facing down.
3. Run Samsung's water-eject, then a 165Hz cleaning tone for 30 seconds.
4. Refold and retest on the cover display speaker specifically.

Fold speakers collect less pocket lint than Flip speakers (because the Fold is larger and rides higher in pockets) but more dust from desk surfaces because the device spends more time lying flat open.

Water resistance on Galaxy foldables

Z Flip and Z Fold have IPX8 ratings, which covers immersion but explicitly excludes dust. That's different from iPhone's IP68.

Practical meaning:

• Foldables can survive a dunk.
• Foldables cannot survive a dusty environment at the same rated level as a slab phone.
• Fine dust entering the hinge mechanism can eventually affect the speakers adjacent to it.

If you use a Fold or Flip in construction, gardening, or any dusty environment, the cleaning routine should run weekly rather than monthly.

Dolby Atmos and audio processing

Samsung enables Dolby Atmos by default on most Galaxy phones. It does real audio processing that can make speakers sound different from unprocessed output.

If you're trying to diagnose muffling, turn Dolby Atmos off temporarily:

Settings → Sound and vibration → Sound quality and effects → Dolby Atmos → Off

Test a voice memo with it off. If audio is crisp with Atmos off but muffled with Atmos on, the problem is processing, not the speaker. The cleaning routine won't help.

Similarly, Adaptive Sound (which adjusts EQ based on ambient noise) can make speakers sound quieter or muffled in quiet rooms. Turn it off during diagnosis.

When to stop cleaning and book service

Samsung repair pricing varies, but some signs that point to needing service rather than another cleaning cycle:

• Audio muffling persists after thorough cleaning and 48 hours of drying
• Crackling at specific frequencies that wasn't there before
• Speaker produces no sound through one channel even at full volume
• Physical damage visible to the grille or mesh
• Water exposure beyond IP rating (hot tub, salt water, prolonged submersion)

Samsung's Care+ covers speaker repairs on newer Galaxy models. Out-of-warranty repair at a Samsung Experience Store is typically in the $100-200 range for the speaker module. Third-party repair is cheaper but often breaks water resistance.

The short version

Run Samsung's built-in water-eject first. If that's not enough, brush the grilles and play a 165Hz cleaning tone for 30 seconds. On foldables, open the phone fully before cleaning and check the hinge separately. Most Galaxy speaker complaints resolve with this sequence and monthly maintenance.

Samsung phones are actually easier to clean than most because Samsung ships the cleaning tool in the device. Using it — along with the basic physical cleaning and a proper cleaning tone — covers 95% of the cases people would otherwise consider hardware failures.
