Actually this is a well-known technique: turn up the volume of the loudspeakers to the maximum and emit frequencies to that the vibration pushes and expels the remains of water that may have entered through these holes. And if you have a Xiaomi or Redmi, the MIUI customization layer has this exclusive function.
How to fix a wet phone speaker
The route to follow to activate this function is as follows:
- Get in the ‘Settings‘ of the system.
- Now scroll down to the ‘Additional settings‘.
- You will find a specific function called ‘clean speaker‘. It’s that.
- Now a test will be carried out for 30 seconds where a frequency sweep will be carried out, from the lowest to the highest, to try to expel any possible element that is obstructing the speakers.
Although this method exists essentially to clean your speakers, it is actually one of the best tricks out there for spit out the water that may have entered your mobile superficially.
If the damage has worsened, do not forget that you have three years of repairs and an official guarantee on each and every one of the Xiaomi products that you have purchased through Spanish stores and shops.

If the system tool itself doesn’t convince you, don’t worry. The FixMySpeakers website, also available as an application downloadable from Google Play, or this other Hoel Boedec application, recommended “when water has entered the smartphone speaker and the sound seems attenuated”.
Both are very practical alternatives to achieve, on the one hand, that the sound improves exponentially and spit out possible obstructions and, on the other hand, protect the internal components so that they do not get wet.
