  2. Remove the case. Set volume to maximum.

Signs water is still trapped

For dust rather than water, use the speaker cleaner sweep mode. To confirm which speaker is affected, run the left/right speaker test.

Frequently asked questions

+Is this the same as Apple Watch Water Lock?

It's a similar idea — Apple Watch plays a tone to push water out. This browser tool works on phones, tablets and laptops, but it is not affiliated with Apple.

+How soon should I use it after water exposure?

As soon as possible, once the device is powered on and working. Wipe it dry first, then run the pulse mode 2–3 times with the speaker facing down.

+My phone is still muffled after ejecting water. What now?

Let it air-dry for a few hours, then try again. If audio remains muffled, the speaker may have debris or damage — contact the manufacturer or a repair shop.

+Should I put my phone in rice?

Manufacturers including Apple advise against rice, since particles can get into ports. Air-drying in a ventilated spot is the safer option.
