Why does the mobile volume go up and down by itself?

mobile sound volume

It is one of the most common errors that occur on smartphones today. Furthermore, it can sometimes be quite annoying and even cause us problems, such as when we do not answer a call because the sound is so low that we could not even hear it. Why does the mobile volume go up and down by itself? In this post we are going to try to answer this question and propose solutions.

The issue of audio has become more important with the passage of time and the evolution of mobile phones. It no longer only has to do with call sound, but also with the volume of audio for music, games, podcasts, etc.  And with him notification sound of the different applications we use.

Those sudden changes in volume can be irritating. The worst thing is that we often come to the conclusion that it is something that we are not controlling well and that It does not allow us to use the device in the way we really want. The truth is that there are many reasons why the mobile sound may have been misconfigured. We review them below.

Hardware issues

The mobile volume goes up and down for no apparent reason. Why does this happen? The source of the problem may be in the headphones that we usually use or in the device's own speakers. Among the main hardware problems that we can encounter, the following stand out:

Volume button failures

The volume buttons, usually located on the side of the phone, are prepared to fulfill their function and are quite resistant. Nevertheless, Sometimes we put excessive pressure on them, which can lead them to the point of getting "hooked." If this happens, the volume remains fixed at a certain level and it is impossible to adjust it using the button.

To unclog the buttons, it is advisable to rub them gently with gauze and a little alcohol. If the blockage is more persistent, the solution is to replace the pads.

But even before that, We must make sure that the case we are using does not compress the home and volume buttons. This can happen if we use a case that is not compatible with our smartphone model.

Cleaning the speakers

With the passage of time and use, it is inevitable that the phone's speakers end up accumulating dirt, or that water or humidity gets into them at some point. As a result, there are foreign elements that block the hole, and the volume of the mobile goes up and down without explanation.

That is why it is convenient clean the speaker of our phone from time to time. There are two ways to do this: manually or through an application.

  • manual methods: blow out the hole with an air bulb, clean it with an ear swab, applying adhesive tape and pulling it.. What we should avoid is introducing pins, toothpicks and other sharp objects.
  • Through applications that unlock the speaker through sounds and vibrations, such as the Speaker water cleaner.

Problems with wearables and Bluetooth connection


Many times the explanation for the situation in which the mobile volume goes up and down without us doing anything has to be found in the bluetooth connection and connected devices, especially wearables such as smart watches or wireless headphones.

It is quite common for the connected device to take control of the volume of the music and the sound in general that we play on our mobile. For example, many cases have been reported related to Apple Watch, which allows you to raise and lower the volume simply by rotating the watch face. In this way, any slight touch with it will have consequences on the volume of the sound.

On the other hand, it is convenient review Bluetooth connection settings, which can affect the quality and intensity of the sound when we connect the phone to other devices. This is what needs to be done:

  1. First we go to the menu Settings of the telephone.
  2. Click on the option "About device" or "Phone information".
  3. select "Build number" and we click on it seven times in a row.
  4. Now we are going to "System".
  5. In rural areas of India, families in charge of a blind minor frequently isolate and deprive him/her of the care and attention they provide to their other children; such situation becomes even more severe among lower-caste families, orphans and if the blind child is a girl. "Development options", we are going to "Bluetooth audio codec", where we will be able to test until we find the one that best suits our preferences and needs.

Software bugs

If all of the above has not worked and random volume increases and decreases continue to occur, it is likely that we are facing a software failure. To fix it, there are some methods we can try:

Reboot the phone

It is the simplest remedy, although in many cases it usually gives good results. Restarting the smartphone is often enough to eliminate the inevitable failures that occur due to prolonged operation of the same. The best way to do this is to turn off your phone and then wait 20 to 30 seconds before turning it on again.

Set the sound equalizer

Almost all current mobile phone models have a sound equalization tool. Depending on the manufacturer, it may be located in the general menu or in the settings. Through this tool it is possible to change the audio mode. Sometimes the “dynamic sound” option which allows the device to optimize the audio automatically according to the type of content, in order to offer us the best experience. The bad thing is that this makes the volume go up or down on its own, without us doing anything.

Hard reset

It is the last option to resort to, since it is the most drastic. A factory reset which will return the mobile to its original configuration, eliminating all sound problems in one fell swoop. If we make the decision to use this instrument, it is important to carry out a Backup. Once this is done, you must proceed to delete all the data. We advise you to read our post dedicated to this topic: How to format an Android or iOS mobile.

Finally, if even with the Hard Reset we have not been able to solve the problem, we will have to consider the possibility of go to technical service in search of a definitive solution.
