Low volume during phone calls is one of the most common problems on smartphones. The signal quality may be sufficient and there may be no interruptions in the conversation, but if the sound is not quite loud enough , the experience of a conversation can be horrendous. Therefore, we are going to see why this happens and how we can solve it.
Depending on the mobile we have, that is, its own factory configuration, and other external factors, the volume may not be as desired . It is something that many users live with every day. Some even have to activate the speakerphone for the hands-free or even use a headset. This will not be necessary if we review the possible causes of this problem and implement the appropriate solutions.
Why are the calls heard under
Before we get into deeper causes, we must perform a series of checks . These tests will be the fastest and possibly solve the problem in many cases. So we recommend you try each of these options. Of course, every time you do one, do a test to check if the audio of the calls from your phone is still low or is already fine.
Restart the mobile
In the same way that when other software problems arise, restarting the mobile should be the first action. Basically, because it is still the solution that can put an end to this specific failure of low sound during calls. If it is a software problem, a simple restart on the phone can free the cache of the terminal, making it work normally afterwards. This happens, especially, when we have not turned off and on the mobile for a long time. Once this is done, we can test the phone again to see if the problem has been solved.
Check for updates
Another of the main reasons is due to a failure in the operating system software . That is, the problem may already be reported, so the firm of your Android phone has already launched a firmware update that solves this error. Therefore, our option in this case will be to check from your Android settings> System> System updates.
Turn up the volume
Although it seems silly, maybe for some reason, or simply because we did not remember, the audio of the conversations has been lowered. Therefore, this step will only be to ensure that during the call the audio is at maximum, leaving the volume up button pressed when the conference is active. If it is at the maximum, we should try the following alternatives that we will explain in detail later.
The volume is low
If after trying the previous alternatives, the audio of the calls is still low … We will have to continue trying the following methods, which will go from less to more to try to definitively solve this sound problem on your mobile phone.
Remove the case or shell
Many users blame the phone, but in reality it may be the case or the shell of our mobile, which is interfering with the headset. The idea is to remove these accessories and try again to try to have a conversation to see if it was the cause of the problem.
Clean the speaker or earphone
It is surprising to see in many forums, how the mere cleaning of the front speaker fixes the problem of low volume . And it is surprising because it is something that not many users fall for, and that, nevertheless, makes the sound adequate again.
Dirt can clog the headset. The solution is to use an alcohol swab to moisten the area and pass it several times to make the dirt dissolve with the alcohol. The next step is to use a pin or needle to very gently poke the speaker grill. This process must be repeated at least twice. After problems check how the sound of the calls becomes loud again.
Use BuidProp Editor
Android terminals have a system file called build.prop. In addition to other parameters, the volume of the earpiece during calls depends on it. With this tool we can improve the sound of conversations. To do this we will have to download the following app so that later you can open the build.prop file:
Then, click on the pencil to edit the file and modify the following lines: ro.config.media_vol_default = 30 Then click on the save icon in the upper right corner and restart the mobile. Now we test a call, since the volume should now be louder.
Clear cache
Another solution is to clear the cache and data of the application of the system that manages the calls. If there has been a conflict with a third-party app, or even if a system file has been corrupted, with this setting we can try to solve it. For this we will have to go to Settings / Applications and search for ‘calls’ . Once inside we touch on Storage and Cache, and then click on User Data and Cache. When deleting the data we restart the terminal and test the volume again with a conversation.
Try in Safe Mode
The safe mode of our mobile allows us to know the origin of many problems. The system will boot without the applications installed by us, so if the call volume is correct in safe mode , it is possibly a third-party app that is causing the problem. The goal is to search through the installed apps, from newest to oldest, that may be causing the problem. Then we will uninstall one by one, testing the calls in between in normal mode, and continue with the next one until we find the failure. We can start safe mode by holding down the shutdown button and tapping ‘OK’ when restart to Safe Mode appears.
Reset to factory settings
When all else fails, one of our last options is to reset the mobile to the initial factory settings. This solves the problem on many occasions, especially when we have been with the device for a long time and there have been hundreds of applications installed and uninstalled in the storage. Once we have our personal data safely, we can click on Settings> System> Reset to factory settings. Once the process is finished, we will perform the test again to see if the problem has disappeared.
Hardware problem
If all the above fails, we can conclude that, probably, the mobile has a hardware problem. Generally, it is most likely that the headset has a problem causing our conversations to be too low in volume. So it will be practically impossible for you to solve it on our own.
Therefore, if after we have been trying to try all these methods to fix this fault, but it continues, we will have no choice but to visit a technical service . In this case, we can do it through the official technical support of the brand of our terminal or in the physical store where we acquire the mobile device, who will give us the steps to follow in the process.
More than anything, because the problem is most likely due to the hardware of the device as we said before. If it was a software bug, the reset, or whatever we’ve done, it would have served to put an end to this audio glitch. Therefore, it is best to make an appointment with a specialized technician who will help us solve the fault and even change the part if necessary.
