Why do they call me and I don’t hear? Why there is no sound on the phone - reasons and explanations

We treat “deafness” in Android smartphones

The modern smartphone has long become a multifunctional device. Today, owners use their mobile phones as webcams. gaming consoles, multimedia players, modems, remote controls remote control and so on. However, the main function still remains Voice connection. Therefore, if the microphone on the phone does not work, then its usefulness tends to zero. This malfunction may have many different causes.

Why doesn't the microphone on my phone work?

First, let's delve a little deeper into the technical sphere of the problem. A microphone is an electromechanical device that converts sound waves into an electrical signal. Thus, for it to function, at least two conditions must be met. Firstly, it is necessary to ensure unhindered passage of sound to the sensitive element, and secondly, the microphone must be in good working order.

And if these conditions are met, the processor receives correct digital data, and nothing else depends on the microphone.

However, the formulation of the question should be expanded. The fact is that the problem due to which the interlocutor can no longer hear your voice is not necessarily related to the performance of the microphone. The reason for the lack of sound may be due to application settings, “glitches” of the smartphone’s operating system, and even a malfunction of the speaker in your interlocutor’s mobile phone.

Let's look at the most common situations.

“Fixing” sound in Skype

So, your interlocutor cannot hear you. In this case, we proceed according to the following algorithm.

• Let's call someone else. If there is no one else to call, we use the built-in Echo service - this service specially designed to check the quality of communication. We call the service and say a few words - the voice will be recorded and forwarded to your phone. If everything is fine, it means that the problem is not with you, but with the interlocutor, for example, the speaker is faulty.
• Let's understand the settings. If no one can hear you, including the Echo service, go to the phone's privacy settings menu and click on the microphone icon. Here we will get a list of programs that have access to the microphone - we should make sure that Skype is among them. If this does not help, try reinstalling the application.
• We use a headset. There are rare cases when Skype flatly refuses to work with the built-in microphone. A radical decision Bluetooth headsets may become a problem. At the same time, you will receive a significant improvement in sound quality.

A fairly common problem that smartphone owners face is poor hearing during conversations. Moreover, both Android and other devices are susceptible to it. operating systems, such as iOS and Windows Phone. I bring to your attention several proven methods of what to do if you can’t hear your interlocutor on the phone.

It’s hard to hear your interlocutor on the phone: causes of malfunction

So what could be the reason that the speaker became quiet or the sound disappeared altogether? In most cases, the problem lies on the surface and does not require the intervention of service center specialists. Let's talk about everything in order:

• If you can't hear one of your interlocutors, you need to make sure that the problem is not on your side. Try making a call to someone you know working phone and check the sound quality. If this is not your case, then move on.
• Check the volume level. To do this, during a conversation, press the volume rocker up and check if there is a result. No result? Read below.
  
  
• Inspect speaker phone for dirt. Often it is the dirt in the speaker grill that causes the sound to deteriorate during a call. If you find dirt, take a toothpick with a piece of soft cloth or a cotton swab and gently wipe the dirty area, lightly moistening it with a drop of alcohol. You can also use a soft toothbrush.
  
  Do not use a needle or other metal objects for this purpose, as this can easily damage the speaker, which will only worsen the problem.
  

  I came across a funny situation when a person after iPhone purchases, leaves the factory film on the screen to protect the screen. But the whole point is that this film covers the speaker and practically nothing is heard during a call. You don’t need to do this, if you want protection, buy yourself a normal protective film or glass, especially since they are not at all difficult

• Make sure you don't have a headset connected to your phone, as this will cause sound to come through the headset and not through the phone's speaker. The same applies to bluetooth headset and other bluetooth devices.
  
  
• Reboot your phone. This will help if the problem is caused by a device software failure.

If none of the methods help, then the problem is more serious and it will not be possible to solve it on your own without the appropriate experience. You need to contact a service center for help.

I'll try to suggest the basic principles of setting up sound in the engineering menu.

On the same phones, but with different version Firmware, engineering menu may differ slightly. We describe using the example of engineering iPhone menu H6.

We enter engineering menu by entering the appropriate code. For example, for some phone models *#9646633#

Go to the Audio menu. By default, the audio settings use three modes:
- normal mode – the main mode of using the phone
- loudspeaker mode – hands-free mode
- headphone mode – headset mode

We choose the sound in which mode annoys us. For example, we don't like the microphone sensitivity in “Normal Mode”. Go to the menu “Normal Mode” - “Microphone”. We observe the menu items “Volume 0” - “Volume 1” - “Volume 2” - “Volume 3” - “Volume 4” - “Volume 5” - “Volume 6”. These menu items determine the microphone signal level when various installations the general volume of the phone, which, if necessary, is regulated by the phone volume rocker. Now, by changing the values ​​in each of the 7 points, you can customize the phone for yourself. The basic principle is “The higher the volume of the speaker, the lower the sensitivity of the microphone” (if there is noise outside, the volume of the speaker is higher to hear the interlocutor and the sensitivity of the microphone is lower, to reduce the transmission of external noise, and vice versa - in a quiet room, with a quiet sound from the speaker, You can increase the sensitivity of the microphone so as not to raise your voice). Minimum value specified parameters- 0, maximum - 255.
Those. set type settings:
Volume 0 - 255
Volume 1 - 235
Volume 2 - 215
Volume 3 - 205
Volume 4 - 195
Volume 5 - 185
Volume 6 - 175

These are not specific values. This is the principle. Specific values ​​may depend on the characteristics of your microphone.
Parameter values ​​are selected using the volume rocker.
Then “Install”.
Excessive sensitivity of the microphone leads to an echo effect when the interlocutor hears himself.

The volume of other audio devices is adjusted in the same way as the microphone:
Speech – speaker level in talk mode
Keyboard Tone – the volume of the beep when you press keys.
Melody – ringing signal volume
Sound – TV and FM volume

Likewise Normal mode– Sets the values ​​for Speaker Mode and Headphone Mode.

Additionally:
In each of the items (Speech, Melody, etc.) there is a final item “16 Level Setting”. It has 2 parameters: Max Analog Gain and Step. This is for setting 16-step volume control of the audio player in the appropriate mode (Normal, Headphones, etc.)
Max Analog Gain is maximum volume audio player. Step is the step to decrease the volume (from maximum) when you press the rocker. Thus, if for example Max Analog Gain=160, Step=10, then the volume will change from maximum (160) to zero. If Max Analog Gain=160, Step=5, then the volume will be from 160 to 80.
These parameters are duplicated in all items (Speech, Melody, etc.); it is enough to set them in one item.
P.S. Their influence on the volume of the video player was not noticed (although there is also 16-step regulation)

What should I do if the person I’m talking to can’t hear me well on the phone? If the device is under warranty, then you can simply contact the service center, where they will repair or replace the relevant parts. What if the warranty has unfortunately already expired? Then you should try to independently determine what is the cause of this defect: software glitch or hardware failure?

Why can't my interlocutor hear me on my Android phone?

You can find out the cause of the problem quickly enough by simply connecting the headset.

At times, simply rebooting the smartphone helps.

Sometimes the consequence of the fact that the interlocutor cannot hear you well on the phone is system failure, which you can try to fix yourself without turning to specialists. In this case, you should proceed as follows:

Frequent users of brand smartphones Sony Xperia dissatisfied with the quality of audibility during communication with a contact, and this situation also occurs in the reverse order. In this article we will look at all possible problems of audibility during communication. In most cases, the issue can be resolved by program level without much effort, free of charge and without having to go to repair centers.

We will consider the reasons in order of frequency encountered by owners of smartphones from this company.

First reason. Software enhancement of sound quality.

There are a couple of functions, the essence of which is to improve sound quality; in fact, not all smartphones implement them adequately. These functions are “Subscriber Voice Enhancement” and “Noise Reduction”. If during a conversation your contact is concerned that your voice is not being heard adequately and this affects more than just one person, try taking the simplest steps to disable these functions. To do this, just go to the call settings and deactivate them. Just keep in mind that your smartphone may require a reboot after the operations performed.

The second reason. I can’t hear the other person due to the type of network

Network settings failed. This is not a common case, but since it’s easy to check, do the following: go to the following points: Settings -> Mobile network -> Network type -> select WCDMA/GSM. We overload the device, in this case, preferably by removing the battery (with technical feasibility, after turning off we remove it)

Third reason. Google OK

A much-hyped Android feature (in practice, it’s nothing more than a toy, and even harmful due to bugs in operation that can affect many programs). This thing sometimes results in the inability to hear the contact. Disable the “Voice search” function in Google services, the settings there are standard and intuitive.

Fourth reason. Serious software failure

From this point on, we move on to extreme ways to solve the problem when the interlocutor is not heard or is hard to hear. And perhaps at this stage it will be relevant for you to contact a special service center - sony-helpers.ru, but if you still want to figure it out on your own, read on.

"Hard Reset" or " Hard reset smartphone to factory settings." Important point- during this procedure, remember that all data (except for those on the card) will be erased, so be sure to make a preliminary backup contacts, correspondence and other necessary information. We will not describe this procedure in detail, because there is a lot of information on this topic on the Internet and it is easily accessible.

Fifth reason. The technology failed

Your earphone or speaker is faulty. The saddest and most expensive thing is that the only way to resolve this situation is to contact a service center where qualified specialists can help you. We do not recommend trying to carry out repairs yourself; if you lack experience, no video tutorial can protect you from causing even greater damage to the device.

As you can see, hiring experts to resolve the issue is not so necessary; you can carry out certain diagnostics yourself without spending extra money. But keep in mind that all actions that you perform on your smartphone will occur solely at your own responsibility.
