The microphone does not work on your Android phone: causes and methods of troubleshooting

How to turn on the microphone on your phone

The microphone on your mobile phone is turned on by default. You can turn it off only during a conversation or in the engineering menu. In the first case, if the microphone was accidentally turned off, then after the end of the conversation it is automatically switched to the active position. If during a subsequent conversation the microphone does not work again, then you need to check its functionality. First, it is recommended to restart your smartphone, and then you can dial the combination *#7353#. This will allow you to go to the engineering menu and check the operation of the microphone there.

If even after turning on the microphone does not work, this may be due to a program failure. In this case, it is recommended to reset your smartphone to factory settings. If necessary, reflash the mono smartphone again. If the problem is a hardware failure, then you cannot do without a service center.

If water got into your smartphone or it was hit, after which the sound disappeared, you should not try to repair the device yourself.

Method 4: Disable VoLTE

Many Internet users who encountered a similar problem were helped by disabling Voice over LTE technology. Thanks to it, the call is transmitted over a 4G network, which increases the quality and speed of voice stream delivery. For the technology to work, the SIM card and phone must support it.

1. In “Settings”, open the “Connections” section, and then “Mobile networks”.
2. Disable the VoLTE Calls feature.

How to turn on the microphone on an Android phone through headphones

When you turn on the headset, the microphone also turns on automatically, but there are exceptions. A common cause of malfunction is that the microphone on the headphones does not work. This may be due to two reasons.

1. Broken headset jack. To check functionality, it is recommended to connect another device.
2. The sensitivity of a device working with headphones can be set to zero. This rarely happens, and you can correct the situation by going to the engineering menu. To do this, you need a special access code, which is unique for each specific smartphone model.

After entering the menu, you need to go to the Hardware tab, select the line there - Earphones and Mic or something similar, the name may change on different models. Sensitivity is determined by the section - Speech Enhancement. Next, you need to try various parameters and make adjustments so that the microphone starts working in the headphones. After setting up, it’s worth remembering all the menu values, in case you still have problems with the sound.

Software glitch

The first reason why the microphone on the phone does not work is a malfunction in the operating system. It doesn’t matter at all what OS is installed on the device - Android, iOS, Windows or any other, failures happen everywhere and they happen spontaneously.

How can you deal with the malfunction? There are several options, and the simplest one is to reboot the device. As a rule, in most cases this completely eliminates the problem and the microphone begins to function again. The second option is more radical - resetting the settings to the factory state. Sometimes a software failure can be much more serious than it might seem at first glance, and a simple reboot will not fix it.

How to set up a microphone on your phone

Many owners of Android smartphones do not know how to configure the microphone on their mobile phone. But its sensitivity is very easy to change at your discretion. Setup won't take much time.

Microphone settings via the engineering menu

To change microphone settings through the engineering menu, you must gain access using a special code. This code differs for different mobile device models. You can find this code in the instructions for the gadget or on the manufacturer’s official website. This code looks something like *#*#54298#*#* or *#*#3646633#*#*. These combinations can be considered universal; they are suitable for most Chinese devices.

To enter the engineering menu, you need to enter the required combination using the buttons and then press the call button. After this, the user is taken to the engineering menu.

A system application appears on the screen with a list of items. Depending on the Android version, the interface may differ slightly. Find the item “Audio” or something similar that contains such a word. In this section you can see the following items:

• Normal Mode – speaker sound, without a headset;
• Headset Mode – sound level in headphones;
• Loud Speaker Mode – sound parameters in speakerphone mode;
• Headset_ Loud Speaker Mode – sound settings when talking in headphones;
• Debug Info – is responsible for restoring factory settings.

Two numbers will be indicated next to each mode. The first is the current volume level, the second is the maximum possible. Accordingly, the first indicator can be increased to the level of the second. Having selected the desired sound level, press the Set key. It is important not to forget that all manufacturers do not set the maximum volume level. This is due to the fact that high volume not only shortens the life of the mobile device, but also negatively affects the user’s health.

How to check if the microphone on your phone is working

If there is any doubt that the microphone is working correctly, it should be checked. This can be done using the Skype application. The program is first downloaded from the application store, after which the following actions are performed:

• First, open the program and select any contact here. However, it happens that there is no one in the contact list and there is no one to call. There is a special service for this purpose called “echo”. This service is designed to check communications;
• When calling someone or using a special service, you should say a few phrases. They will be automatically forwarded to your smartphone, which will allow you to check the functionality of the microphone.

In addition, you can use other means of obtaining information. For example, you can simply call someone from your family or friends. You need to ask the interlocutor how well he hears you.

You can also use a special application in which you record your voice and then listen to the resulting recording. If you can’t hear your own voice on the recording, then indeed the microphone is not working correctly. In the same way, mono record a video and listen to the sound; if there is none, then the device does not work.

Poor contact

Oddly enough, falling a smartphone is also often the reason why the microphone on the phone does not work. This is especially true for budget devices from little-known manufacturers, since their build quality is very poor.

Actually, what are the dangers of falling devices for the microphone? It's simple. If dropped, there is a risk that the microphone cable, which is connected to the main board, may break contact or be completely disconnected from its connector. As a result, the microphone will either work with serious interference or stop completely.

There is only one way to fix this problem. You need to disassemble the device and connect the cable in its place. You can do this yourself or take the device for repair.

The microphone on the phone does not work - what to do?

If the microphone does not work correctly, and the settings do not help correct the situation, then there may be some kind of breakdown. In some cases, you can solve the problem yourself, but more often you have to contact a service center.

Moisture has entered

If moisture accidentally gets into the microphone, the other person may have difficulty hearing you during a conversation. This occurs due to oxidation of contacts. Oxides can form near the microphone, as well as in the system connector, which is used to connect the headset.

To fix problems, it is enough to clean the oxides. But if moisture suddenly gets into the microphone itself, then most often it needs to be replaced with a new element. In some cases, a special EMIF filter may also need to be replaced. It is better to entrust such repairs to a specialist.

Smartphone after impact

After mechanical damage, the smartphone may also stop working normally. If the impact was strong, then the track in the middle of the board, which is responsible for the sound, could break; in this case, the part needs to be replaced with a new one.

The chip inside the mobile device may also be damaged. To fix the problem, you need to find out the exact cause of the failure. Specialists at the service center can determine the damaged area of ​​the microcircuit, and they will also repair the mobile phone.

The microphone is clogged

As you use it, the microphone on your smartphone gets clogged, which is not surprising. Small debris and dust often get into the small opening of the case. When the microphone is clogged, a defect in voice transmission is often observed. Wheezing and other extraneous sounds are heard in the tube. Only in rare cases does the interlocutor stop hearing you altogether.

To eliminate such a defect and improve audibility, just carefully clean the hole with a toothpick or needle. You need to act very carefully, as there is a high chance of completely ruining your mobile device.

Accidental damage to the microphone

Careless attempts to clean the microphone hole can sometimes damage it. If the user carelessly cleans the connector with a needle or toothpick, he may accidentally break the soldering of the controller or processor.

The defect in this case manifests itself in a quiet sound. The interlocutor’s voice is loud and extraneous sounds are heard. If the microphone failure is serious, then the element must be replaced at a service center.

Software errors

A common cause of microphone malfunction on a tablet or smartphone is various software errors. To fix this problem, you first need to restart your mobile device and make sure that the problem with the microphone is definitely related to a software glitch.

You need to remove the battery and wait 10 seconds. After this, the battery is put back into the mobile phone and turned on. Next, you need to make a call to one of your friends to understand whether the microphone is working or not. If the problem is not solved, then you need to connect the smartphone to the computer using a cable. You should make sure that the latest software version is installed on your smartphone. Otherwise, some applications may not work correctly.

You can also check what exactly the problem is using a Bluetooth headset. If the interlocutor hears you well during a conversation, then the problem is clearly not in the microphone.

If there is no special cable and it is impossible to synchronize your smartphone with a computer at home, then it should be taken to a service center.

Dust and dirt

The next reason why the microphone on your phone may not work well is dust and dirt. The microphone holes on the body of your device are quite small and often become clogged with small dust particles and particles of dirt. As a result, the sensitivity of the microphone is significantly reduced, and if it is very dirty, it almost disappears.

This problem can be fixed quite easily:

• First you need to try blowing air through the microphone. You can try to blow it yourself or use a can of compressed air.
• This may not always work, since dust and dirt particles can accumulate quite heavily. In this case, you will have to use a thin needle (or any other thin object). It should easily penetrate the microphone hole, and with its help you can remove all the dirt that has collected there. You just need to act as carefully and carefully as possible, without pushing the needle too deep, otherwise there is a risk of damaging the microphone itself.
