About Speaker Cleaner: Water Eject
An app that pushes water out of your phone speaker with low-frequency vibration, and then measures how much of the sound came back.
■ You can see whether it worked
Other apps only play a tone, so you never know if the water actually came out. This one plays the same test tone before and after, picks it up with the microphone, and shows the difference in dB. Water blocks the high notes first, so the recovery of the high range is shown separately.
■ No limits, nothing to buy
The ads are a banner at the bottom and an ad that may appear when you open the app, at most once an hour. It does not appear during a measurement. No feature requires watching an ad, there is no limit on how many times you use it, and there is nothing to buy.
■ A sweep, not a single note
The tone sweeps from 55 Hz to 235 Hz and back every 2.4 seconds. Which frequency shakes the water loose depends on how the phone is built, so a sweep covers more ground than one fixed note. The default run is 18 seconds.
■ The app looks after the volume
It raises the volume while the tone plays and puts it back where it was afterwards. The first time, it tells you that it is about to get loud.
■ It works without the microphone
If you do not allow the microphone, the water ejection still runs. Only the before and after measurement is skipped.
Good for
・A sink, a bath or a pool
・Rain, in a pocket or a bag
・A spilled drink
・Sound that is muffled, quiet or crackly
・Dust that you think is stuck in the speaker grill
How to use it
1. Point the speaker downwards, resting or in your hand
2. Press Start
3. When the tone ends, look at the before and after numbers. If nothing changed, run it again
What to know
Water often takes a few runs, and one run may not clear all of it. This cannot be guaranteed to remove water that has worked its way inside, and it is not a replacement for waterproofing or for repair. If your phone has just been in water, dry it properly instead of forcing it to keep working. The microphone is used only for the before and after measurement, and the sound itself is never recorded or sent anywhere.
