No — and this matters. The sound has to travel through the blocked speaker to do anything, so any connected Bluetooth or wired device defeats the purpose entirely. Disconnect everything first.
Tap the button below. It plays a low‑frequency sound that vibrates the speaker and pushes trapped water and dust out of the grille. Turn your volume up to about 80%.
💡 Point the speaker downward so gravity helps the water escape. Repeat 2–3 times if needed.
This tool is optimized for OnePlus devices. Select your exact model for the most reliable result.
Dry the outside of your phone first.
Let gravity help pull the water out.
Ensure audio plays through the phone's internal speakers.
Never use earbuds. Turn volume up, but 100% isn't required.
Our tool is designed to target the three most common speaker issues using precise acoustic frequencies. Whether your phone took a dive or just sounds muffled from pocket lint, here is how we fix it.
Clear trapped water from your phone in about 60 seconds. The steady 165 Hz vibration physically pushes trapped liquid out of the speaker mesh.
A steady 165 Hz tone — the sweet spot for maximum diaphragm travel — physically pushes trapped water out.
Use our deep clean mode to act as a dust remover. Sweeping low frequencies shake loose stubborn dirt, sand, and lint.
Sweeps across low frequencies (120–400 Hz) to shake loose lint, dust and stubborn droplets the single tone misses.
Act as a volume booster for muffled speakers. Clear out blockages to restore heavy sound, loud bass, and crisp audio.
A clean 440 Hz reference tone so you can hear whether your speaker sounds clear again after cleaning.
Perfectly safe. These are ordinary frequencies your speaker already plays during music. The tool never exceeds normal listening levels — it just concentrates the energy at the frequency range where diaphragm travel is greatest.
OnePlus provides a genuine engineering diagnostic, and its hardware has one quirk that contributes to grille debris on most models.
For a complete overview, see the complete Android guide.
Dial *#808# from the phone app to open OxygenOS's diagnostic suite. It includes separate tests for
the loudspeaker and the receiver, which isolates each driver rather than leaving you to judge by ear. Codes vary
by model and firmware — if nothing happens, the menu is unavailable on that build.
OnePlus's physical alert slider is unrelated to audio, but the recess it sits in collects pocket lint readily, and that debris migrates along the chassis edge toward the speaker grille. Cleaning the slider recess with a soft dry brush while you work on the speaker is worthwhile — it removes a continuing source rather than just the current symptom.
Recent flagship OnePlus models carry IP68. Nord-series devices are considerably less sealed, and some carry no certified rating at all despite marketing that implies resistance. Check your specific model rather than assuming the range is consistent — the gap between flagship and Nord is genuine.
Bottom-firing main driver paired with the earpiece as a tweeter and second stereo channel. The earpiece contributes less bass by design, so mild stereo imbalance is normal rather than a fault.
Inside the SIM tray slot. White is clear; pink or red means liquid reached the internals.
OnePlus's fast charging pushes significant current, which makes charging a damp port a worse idea here than on a slower-charging device. Do not override any moisture warning. Wait 24 to 48 hours in moving air.
Case off, brush the grille and the alert slider recess, Bluetooth fully off, volume 70–80 percent, grille
facing down at roughly 45 degrees. Three cycles with brushing between each, then verify using
*#808#.
No — and this matters. The sound has to travel through the blocked speaker to do anything, so any connected Bluetooth or wired device defeats the purpose entirely. Disconnect everything first.
Eject the liquid the same way, but treat the device as needing professional attention afterwards. Salt and sugar leave conductive, corrosive residue when they dry, and that residue keeps damaging the board long after the speaker sounds normal.
Stop. If three cycles produce no improvement at all, the cause is not blockage. Check the symptoms on our guide to when a sound tool will not help, and have the device inspected rather than continuing to run cycles.
No. The frequencies used sit inside the range your speaker already reproduces whenever you play music, and the tool runs at moderate volume rather than maximum. The one genuine caution is earbuds: never run ejection tones into in-ear devices while you are wearing them.
No. Around 70 to 80 percent is the practical sweet spot. Maximum volume on a restricted diaphragm produces distortion rather than more displacement, and adds avoidable stress to the driver.
Our tool is great for water and dust, but it cannot fix physically blown speakers or electrical damage.
