Cellular communications today are the main means of communication. Telephones are an absolute blessing if the device is working properly and we live in a region with a good signal.
But what to do if it’s hard to hear your interlocutor on the handset when talking on a Xiaomi Redmi smartphone—we’ll talk about this in this article. Let's look at all the popular cases and find ways to solve these problems. For smartphone models Redmi Go Xiaomi Redmi Note 7 Redmi 8 Note 8T
Why is it hard to hear the voice on a Xiaomi Redmi phone?
If your friend’s voice is practically inaudible from the mobile speakers, the culprit may be one of three parties: your phone, the phone of the interlocutor and the cellular operator. The reasons can also lie in the basic settings of the mobile phone, or they can be more serious: speaker failure. Since the advent of cellular communications, the process of “catching” a signal has not lost its relevance today. In many villages and areas remote from cell towers, subscribers still have to search for the best conditions for making calls.
The main problem is faulty or unkempt speakers of mobile devices.
Almost any phone model protects the sound of the device being played with a special mesh. And it often becomes clogged with dust, debris from our pockets and other impurities.
Cleaning them will help strengthen the interlocutor's voice if the muffling is minor. If there is no sound coming out of the speakers at all, then it’s time to take your cell phone to the nearest service center for repair. But don’t rush to send the device in for repair just yet. Our recommendations should help even in difficult situations.
Disabling the Google Now app
This application is part of the “Ok Google” function, so the interlocutor may be hard to hear.
- In Google settings, go to “Search & Now” or simply “Search”.
- Go to the “Voice” subsection.
- We are looking for the “Ok Google detection” option.
- Disable all functions.
Determining the Causes of a Quiet Sound
To take action and fix the problem, you must first determine the source of the problem.
| Problem | Action |
| If you have trouble hearing your voice with a certain caller | Try calling someone else. He may be the only one whose speech you can barely understand. And in this case, you have nothing to eliminate. The problem is either in his phone or in the cellular operator whose services he uses. Contact him in another way and notify your friend that the problem is on his side. |
| If you have difficulty understanding the speech of all the subscribers you are trying to call | First you need to restart your mobile device. To do this, there is a special button on the top or side of the case. It must be pressed and held until the shutdown confirmation window appears. |
Modem firmware software error
The treatment for a software error is to replace the firmware. Many desperate people, having tried a million ways and reaching a dead end, rushed to look for a way out on the forums. Countless messages written as carbon copies. I tried everything, tell me what to do. And the answer is almost always the same.
Change the firmware, do a full reset, switch to custom!
I also want to put in my two cents. In principle, the idea is reasonable and will definitely have to be updated. And completely. There are themes available on 4pda with separate archives of modems, ending with the latest versions. But I don’t see the point in fiddling with them and installing only them. Spend the same amount of time. After all, for their spot installation you will need an unlocked bootloader and a pre-installed custom recovery. Everything is the same as for loading the OS itself.
So. You need to flash it. But before you start, you need to be completely sure that the decision you made is correct. To do this: turn off the entire Internet, set the preferred connection type to 2G and try to make a call. If all this has led to the conversation being straightened out, install new firmware after doing a Hard Reset of Xiaomi .
How to clean your smartphone speakers
Xiaomi Redmi mobile devices often have multiple speakers. Some for playing sound during speakerphone and music. Others are for outputting sound during a conversation in normal mode. The latter is located at the top on the front side of the mobile device case.
Just in the place that we habitually apply to our ear. The mesh of this speaker needs to be cleaned if you have difficulty hearing your interlocutor on your phone.
Before doing this, you should turn off your smartphone. To clean, you will need a regular toothbrush, which is found in every home.
Only after using it will you need to buy a new one. Or use the old one, which has already served its purpose. It is necessary to pay attention to the principle of intersection of the mesh bars in order to more effectively remove all debris. It is also better to turn the Xiaomi Redmi smartphone face down and raise it above your head so that you can see where to place the brush head.
If you follow this advice, debris and dirt will not get inside your phone. Where they can cause even more harm. All unnecessary elements, coming off the mesh, will fall down to the floor. You can complete the cleaning session with a cotton swab soaked in alcohol. You should also clean it with a stick: turning the phone face down and lifting it above your head.
For these purposes, non-standard, but no less effective means are often used. For example, a cream to eliminate blackheads on the face. The principle of their work is better known to women.
It is necessary to spread a thin layer on the area with the mesh and wait until the cream hardens. After this, tear off the elastic mask. And with it you will remove almost all the dirt from the speaker mesh.
When talking on the phone, the sound goes through the loudspeaker, not the earpiece
As I wrote above, technically these are the same sound-reproducing element, but operating in different modes.
To switch them, there is a special button in the conversation menu on the phone, it is located to the left of the red button “Reset call” , which you see while dialing a number or during a conversation.
If the speaker icon glows blue, the speakerphone is turned on for hands-free calling. Click on the icon, it will turn gray, in this mode you should bring the phone to your ear and talk as usual.
The volume in both modes is controlled by buttons on the side of the phone.

Increasing the volume in the Xiaomi Redmi engineering menu (instructions)
This method is suitable for most Xiaomi Redi mobile phones. Not all users know that this operating system has an engineering menu that makes it possible to change inaccessible settings. Getting into it turns out to be not so difficult. You need to unlock the screen and enter the following numbers without entering anywhere: *#*#3646633#*#*.
The combination must be entered without spaces.
After entering the last character, the smartphone will open a previously unseen menu for you:
- Depending on the model and manufacturer, the engineering menu may look different. You need to find the “Audio” item;
- Then select "LoudSpeaker Mode";
- In this menu, scroll down the screen if necessary to find the “Max. Vol." with a numeric value. This can be set to 140, 148 or something else;
- You need to manually enter 160. This is the maximum value of the smartphone's ear speaker. Finally, click the “Set” button next to the number.
Now exit this menu, restart your device and try calling your loved ones. Or a subscriber with whom the sound from the smartphone speaker was quiet during a conversation. If the provided code is not suitable for entering the menu, try to determine it for your model by creating a request in Google or Yandex search engines. There are also special utilities that help open unusual menus. But most of them require root rights. Having which you can increase the volume of the speakers without utilities.
To get root rights, you need to read the instructions. Which also need to be found through a search. A few years ago, this procedure scared many Android smartphone owners. Today, phone hacking is easier. And you will need a minimum of effort and knowledge to become an Android superuser.
Turning off the noise canceling feature
Before this, we tried to enable this function, but if it did not help, then, having elevated user rights, we will disable it.
- Launch the explorer application: Root Explorer or ES Explorer.
- Find the file in the following path: \system\build.prop.
- Open and edit as follows.
ro.qc.sdk.audio.fluencetype=none
persist.audio.fluence.voicecall=false
- In the settings, turn off the “Noise Cancellation” function.
- Reboot the phone.
If the above method does not solve the problem and the file has not changed, try downloading a tool from the app store to change the contents of build.prop. For example, you can download Build Prop Editor. Naturally, the application will require superuser rights.
Additional Tips
If there were no problems with sound on Xiaomi before, but now the speaker on your phone has become quieter, try resetting the settings to factory settings. This can be done with any mobile operating system.
For example, on Android the process looks like this:
- Open settings;
- Select "Backup and reset";
- Click on "Reset"
- Confirm the setup and wait for the process to complete
After rebooting and cleaning the speaker, you should not be able to hear clearly the person you are talking to on your mobile phone. If the problem persists and you don’t know what to do, contact your nearest service center.
Changing values in the system file
This method is relevant for those users whose headphones sound is not loud enough. To change system settings, your device must be Rooted. You can read how to install them here. Download any file manager, for example, ES Explorer. Go to the “Root Explorer” item, search for the next file “mixer_paths_tasha”. We open the found file and see many lines, we only need:
The values are highlighted in red (in our case 11), you need to replace them with “16”, save the changes and restart the smartphone.
Microphone check
This option is suitable for checking the microphone for working condition:
- open the Voice Recorder application, record your voice in different tones and check for defects in the recording;
- in the dialer enter the command *#*#64663#*#* or *#*#6484#*#*;
- find the Loopback test and check the microphone;
