The call does not work on the smartphone. Signs of missing or unstable sound

When in Nokia phone there is no sound, this is almost a disaster: the device ceases to correspond to its main functional purpose.

Typical sound-related complaints

1. The bell is not heard.
2. The subscriber's voice is not heard.
3. The subscriber cannot hear.
4. There is no sound in the headphones.
5. Speakers don't work.
6. The device does not play music or sound when watching videos.

The main reasons why there is no sound in Nokia

1. Settings failed.
2. Mechanical damage due to a fall or impact.
3. Pollution.
4. Contact with water.
5. Software malfunction.

Settings

First of all, you need to check your phone settings.

1. Turn up the volume.
2. The silent mode may be turned on.
3. If the sound disappears after turning off the headphones or in the headphones after turning them on, try disconnecting/connecting the headset again. In the worst case scenario, rebooting the device helps.

Mechanical damage

The disappearance of sound most often occurs due to the following breakdowns:

1. Failure of polyphonic or conversational speakers.
2. Damage to the headset jack.
3. Damage to speaker/headset switching.
4. Damage to the microphone.
5. Damage to the amplifier.
6. Loop break.
7. Headset malfunction.

If your Nokia has lost sound due to mechanical failure, the fault is corrected in the workshop by replacing the corresponding part.

Pollution

Clean dirty/dusty contacts only with alcohol or special compounds for electronics. The use of metal objects and abrasives is prohibited.

Water

Remove the battery and SIM card, shake out and wipe off the water, and dry the device. This is sufficient for surface contact with water. In the event of a serious “drowning”, if the damage has affected the working units, it is impossible to remove oxidation products; replacement of parts is required.

BY

1. If your Nokia has no sound after installation third party application, sometimes it is enough to delete the application and restart the phone.
2. If you have serious problems with your Nokia software, we recommend contacting service center. You should not flash a new phone on your own, because... The device will lose warranty.
3. If the warranty is no longer valid, you can reflash the phone yourself; there is appropriate software for different models on the Internet.

Hello! There is a problem with the sound. While I was watching the clip, the sound began to disappear. After he completely disappeared, I turned the phone off and on. Everything seemed to work again, and then the sound disappeared again. I reset the settings, took out the SIM card, battery, flash drive - nothing helps. When I turn on the headphones, the sound works. When they call me, there is only vibration. When talking to another subscriber, you can hear everything, but as soon as you switch to the loudspeaker, the sound disappears. I'm inclined to think it's simple system error or something like that. Help me please. Thank you in advance(:

The phone lost sound when playing melodies and the hearing speaker also does not work. Although the alarm clock plays and everything. He himself is a master in this matter. And there is one more nuance near the volume scale there is a headphone indicator. Although they are not connected. Even when I took it apart and turned it on without touching the headphone input, it indicated that they were connected. Thank you.

Good afternoon, Denchik. If you are a master, download the diagram to your smartphone and check all the elements along the headset detection circuit, something like headphone_detect, look at everything again under a microscope, you may find out what’s wrong. Good luck.

Note: If your iPhone is stuck in headset mode, use the tips suggested in.

Step 1. Go to menu " Settings» → « Basic» → « Universal access».

Step 2. Select a section AssistiveTouch.

Step 3: Toggle the switch AssistiveTouch V active position. A button responsible for working with the function will appear on the screen.

Step 4. Click on the AssistiveTouch button and in the window that opens, select “ Apparatus».

Step 5: Set the sound option to " On sound", after the button " Louder» Set the volume to maximum.

Step 6: Make about 30-40 calls on your iPhone.

One of the calls will have to return your iPhone full-fledged performance. If this does not happen, there is likely a problem technical plan and, alas, you cannot do without a trip to the service center.

If there is no sound on your smartphone incoming call, do not rush to contact the service. The problem can often be solved on its own. But in order to choose the appropriate method to resolve the problem, you need to find out the cause of its occurrence.

The most common causes of sound disappearance

Most often, the reason for the disappearance of sound is not system failures or problems with the device, but simple errors in the settings.

Volume level at minimum

Incorrect volume setting is the most common reason for no sound during calls

To fix the problem, press the volume up button and move the slider to the right until maximum value. Make sure that the other signal levels are also normal. Click the icon to the right of the slider. The volume levels of all signals (melody, multimedia and alarm) will open. If there is no icon, then go to the phone settings in the “Sound” section and increase the volume of each signal.

The sound is in Vibrate or Silent mode

Sound settings on Android are located in the “Device” tab

Sometimes the sound randomly switches from normal mode to the “Vibration” or “Mute” (“Quiet”) mode. Go to the sound settings or system profiles and select a different mode.

Glitch in Android software

The sound may also disappear if a glitch occurs in the software.. You can try to fix it by rebooting your phone.

The person calling you is on the “black list”

The principle of deleting and blacklisting a person on almost all smartphones with the Android system is identical

Sometimes you can mistakenly add a person to the “black list” (block all calls from this contact). As a result, the subscriber calls, but cannot get through. Sound incoming call it won't be.

To make sure that the caller is not on this list, go to the “Contacts” section, select the right person and open that contact's menu. Select "Remove from blacklist" or "Unblock".

Speaker failure

Replacing the speaker with budget models can cost an average of 1000 rubles

If there is no sound in all programs and applications, and not just with an incoming call, try connecting headphones. If sound appears in them, it means that the speaker is most likely damaged. To replace it, it is better to contact a service center.

Other reasons for no incoming call sound

If, after checking all the settings and speakers, the sound problem is not resolved, you should look deeper for the problem.

Incorrect firmware version or failed update

To return to factory settings, while turned off, press the power button and volume up button simultaneously, then select Hard Reset

If the sound disappears after flashing or updating the phone, then the problem may be that the service responsible for sound is turned off:

1. Go to Settings and open the Applications and Application Manager tab.
2. Among the running applications and processes, find the sound service, open it and enable it if necessary.

A more complicated case is when new firmware or the update is missing necessary drivers for your phone's speaker. Then you will need to roll back the firmware or reset the system to factory settings. This will delete data from your phone's memory, so it is recommended to first run backup data.

To return to previous firmware you need to download it from the Internet, and then reflash the phone again.

It's easier to reset your phone and Android version to factory level. To do this, go to “Settings” and select the “Backup and reset” section. All data from internal memory(but not from a memory card), and you will receive the phone in the same condition as when you purchased it. Then from the previously created backup copy move all the information to the phone and all data will be restored.

Conflict between installed applications and smartphone software

The sound of an incoming call may have disappeared after installing a new application. In this case, the problem can be solved by deleting recently one by one installed applications or by digging into their settings. For example, messengers, Skype, Viber, and navigator applications have a function to turn off notifications and sound. The sound of an incoming call may also disappear.

Install programs on your smartphone only from trusted resources, preferably from the Play Market. It is also useful to install an antivirus that will block malicious files.

If the sound disappears on Android, this may indicate a failure in software, settings failure or hardware failure.

Today we will list all the steps you need to take if you encounter such a problem. The main thing is not to panic!

1. Act one. Check your settings

It happens that the sound disappears in one program or section. For example, it is available in applications, but not when making a call, or vice versa. It also happens that the sound is in the alarm clock and nowhere else.

Be sure to first check whether there is sound in applications and in the alarm clock, as well as on the phone in general. To do this, run different programs and operating modes.

You need to do the following:

• Some phones and tablets have the option to see all the volume sliders on the home screen. To do this you just need to click on mechanical button increase or decrease the volume. After this, the main slider will appear and if you tap on the down arrow to the right of it, at least two more sliders will open. Try this.
• If you see that some sliders are on minimum level, move them to maximum. Everything is very simple.
• If your device does not have the ability to see these sliders on the main screen, go to the settings and open the “Sound” section there. You will see the same sliders shown in the image below.

Rice. No. 1. Volume sliders

Sometimes these settings can get lost regardless of the user.

The first step also includes checking profiles.

The Android operating system has several profiles, such as “Normal”, “Silent” and so on. Again, sometimes they turn on on their own or the user turns them on due to inexperience.

So, in such profiles sometimes complete silence is provided. Therefore, be sure to go to settings, select “System profiles” and try choosing a different mode.

Rice. No. 2. "System profiles" in settings

Again, if you notice that profiles are changing without your knowledge, it is better to simply update the operating system. Most likely, there are some glitches in it. This is especially true for cases when the user uses some kind of custom firmware or something like that.

Advice: If no checks help, you may need to do full reset settings. You need to complete this task before updating operating system. This article describes how this is done. First, use a normal reset, and then, if nothing changes, copy all important data to a flash drive or to cloud storage and then do hard reset through the system menu.

2. Act two. Check the sound in your headphones

The cause of the above problem may be the failure of the speaker, that is, the mechanical sound source. Checking this is quite simple - you need to connect the headphones to the device. If there is sound in the headphones, the problem is definitely something mechanical, most likely in the dynamics.

There is one interesting program, which allows you to identify hardware problems on your tablet or smartphone. It's called Phone Doctor Plus. You can download it.

And you need to use it like this:

• Click on the testing icon at the top.
• Select the “Speaker and Microphone” block.
• On the next page, click the “Play” button.

Rice. No. 3. Testing the speaker and microphone in Phone Doctor Plus

As a result, you will see what the problem may be. If it's something software, you can fix it right away. In most cases, such problems are resolved by resetting the settings or updating the operating system. Perhaps we should do this again.

But if the cause of all the troubles is a mechanical component, everything is much more serious.

Perhaps the issue is:

• malfunction of the sound amplification circuit;
• damage or complete breakdown of the cable;
• malfunction of the speaker itself.

In principle, nothing more can happen. Such problems cannot be corrected without appropriate experience. You will have to resort to the help of professionals.

And if you have experience, then you know perfectly well what a cable is and can disassemble your smartphone or tablet to check all the cables for damage. The speaker looks like the picture below.

Rice. No. 4. Phone speaker

In any case, if the problem is not in the software, it is better to take your smartphone or tablet to warranty repair(even if the warranty has expired, it’s better to pay). The problem will be fixed there quickly.

The main purpose of any phone is to communicate with another person. If during a conversation the interlocutor is hard to hear or the speech is cut off and interference appears, then, accordingly, the usefulness of such a conversational device sharply tends to zero.

On modern mobile devices, in addition to communication, there are many other functions. So with their help you can listen to music, watch movies, play games, use various applications. All this entertainment will be less interesting without accompanying audio effects.

Let's try to figure out why the sound on the phone doesn't work? What can cause this type of malfunction and how can it be eliminated? Although all mobile phones have their own device, but general signs Problems are observed in all models.

Signs of missing or unstable sound

Let's look at the main signs by which we can say that the audio signal has disappeared on the mobile phone.

• the first sign can undoubtedly be called complete absence any sound signals;
• can be heard during a conversation extraneous noise or creaks coming from the speaker;
• the interlocutor’s voice periodically rises, falls or is interrupted;
• melodies are not produced or their sound changes, crackling sounds are heard.

If the signs are not so obvious or occur periodically, this may mean either an accidental failure or the beginning of the speakers or other parts of the cellular device to fail.

Let's check

To figure out why the sound on your phone doesn’t work, you don’t have to immediately run to the service center. Perhaps the cause of the problem is trivial. To do this, you should first check the external regulators or check the settings in the mobile phone menu.

Both operations will not take much of your time. Although each mobile has its own design features, all of them have an external volume control and menu subsections responsible for audio.

Video: Setting up sound through the engineering menu

Volume control

The first thing you should do if you have a problem with poor sound on your mobile device is to check the regulator.

It is usually located on the right side of the mobile phone body. There may be several types:

• in the form of a solid button. The sound is adjusted depending on the pressing of a certain end. On the one hand it decreases, on the other it increases;
• as individual buttons, which display plus or minus icons.

Make sure the slider is set to the right level. Move it if necessary. If the problem was in the regulator, then the adjustment should fix it.

IN normal condition the audibility of the call changes, system commands. In order to increase the voice of the interlocutor during a conversation, you need to make adjustments precisely at the time of the conversation or during a call.

To increase the sound when playing video or music, as well as in games and applications, adjustments should be made specifically when open files multimedia.

Volume in the setup menu

If external adjustment does not bring results, it is quite possible that the reason lies in the system settings.

To check you need to do several steps:

• go to the “Menu” section on your device;
• in the window that opens, find the “Sound” subsection;
• On the “Volume” tab, move the slider in the desired direction.

By these actions we will increase the overall audibility of the phone. Like the external control, the sound settings can be divided into separate parameters: for multimedia, for conversations. Depending on the symptoms of the problem, make the necessary settings.

The reason for the silent sound may also be one of the modes of your device. There are “silent”, “quiet”, “on the plane” and others. Accordingly, if you replace one of these modes with a simple one, the problem may be resolved.

Main causes and solutions

If conducting regulatory checks and system settings did not eliminate the problem, then the reason lies elsewhere. These could be either software glitches or mechanical damage or failure of one of the device parts.

Accordingly, depending on the type of malfunction, there is a method for eliminating it. In some cases, you can do it on your own and with minor manipulations, and sometimes you can’t do it without the help of a specialist.

In any case, first of all you should find the original source of the breakdown and only then decide how to fix it and whether it would be advisable to do so.

The speaker is broken

One of the reasons for the loss of any audio signals is a broken speaker. This is a serious malfunction and in most cases can only be solved by replacing the part.

It should be said that modern mobile devices have 2, or even more speakers. Usually one is responsible for music, games, applications, the second is for conversations. If sound is not produced from any of them, then most likely the problem lies in other causes.

One of the simplest ways to check whether it is broken speaker- This is to switch the conversation to the loudspeaker. If the interlocutor can be clearly heard, it means that a breakdown has been detected.

Types of breakdowns and ways to solve them.

• One of the reasons for the deterioration of audibility from the speaker may be its clogging. The sound in such cases decreases, but does not disappear completely. You can try to clean the speaker using a thin needle, a cotton swab or a toothbrush. This is best done with compressed air;

Important! The main thing is not to overdo it and not damage the membrane during cleaning.

• There is a short circuit in the speaker coil or it is burnt. It is difficult to hear a person or sometimes crackles. Solved by installing a new spare part;
• there is a break in the coil. The sound disappears completely. It can only be fixed by replacing the component.

Important! In cases of decreased audibility in a mobile device, problems with the speaker occur in 80% of cases.

Audio amplification circuit malfunction

It often happens that a mobile device's audio amplification circuit fails. In such cases, when adding or decreasing the volume, audibility will not change. It is quite difficult to fix this problem yourself. It is best to contact a service center, where they will carry out diagnostics and replace the amplification circuit.

Reasons why the amplification circuit may burn out:

• mechanical damage;
• when the mobile phone is operating in a heavily overloaded mode and its temperature has risen significantly;
• liquid ingress;
• factory malfunction of the amplification circuit.

Broken cable

One of the most common breakdowns is the failure of the cable. Most often, such a malfunction occurs in sliders and clamshells. Since every time you open the device, the cable itself moves, which leads to rubbing of the contacts.

The main symptoms are loss of audio signals and failure of volume controls. When replacing the part, all problems should disappear.

In addition to chafing of the cable connection, its malfunctions can also be caused by physical damage or moisture getting on the contacts.

Software glitch

Every day the number increases useful applications for mobile phones. Unfortunately, not all of them pass a sufficient level of testing for compatibility with various models mobile devices. Not to mention obviously harmful programs.

Some software glitches can be simply fixed by uninstalling the installed application. Some require a factory reset. More complex conflicts that started a chain of failures will require reflashing your cellular device.

Mechanical damage

Happen quite often. Not every device can withstand being dropped or hit by a heavy object.

Mechanical damage can be divided into three groups::

• external faults. If dropped, the speaker or volume control may be damaged. In this case, the visible faulty part should be replaced;
• damage to microcircuits. After an impact, both the cable and the sound card or other fragile elements of the device, the defects of which are visually impossible to see without opening. You need to disassemble and then understand which element is damaged and, if possible, repair or replace it;
• cracks in the main board. The worst of the options. Depending on the model of the device, it may be more advisable to buy a new mobile phone than to have it repaired.

Pollution

If dust or small debris gets on the phone contacts, the boards or parts may burn out. More easy option– this is contamination of external parts. This could be the speaker grid, by cleaning which you can remove the negative effect.



It is better to do cleaning with special devices and tools, or even better to entrust this task to professionals.

Moisture has entered

Rain, snow, dew or any other liquid that gets on your mobile phone is unlikely to prolong its life. This also applies to any parts of the device responsible for playing audio signals. Excess moisture can cause any components to burn out or contacts to oxidize, which will ultimately lead to loss of voice or music

If you manage to notice the problem in time, the consequences can be minimized. You should turn off the phone, carefully disassemble it and leave it to dry. It is advisable to wait long time, since the desire to quickly check the operation of the device can lead to its final breakdown.



Losing sound on your phone is of course an unpleasant situation, but in no case should you panic. Perform an initial check of the volume controls and settings in the menu. Then check various programs and apps that may mute the volume or cause crashes.

If the fault lies inside the device, then it is better to turn to professionals who will carry out comprehensive diagnostics and return your mobile device to working order without any problems.
