Although the different problems with the microphone of the mobile are not frequent, the truth is that it can be one of the most annoying inconveniences that we can experience as users of a telephone… Isn’t it frustrating when you are in the middle of a call and suddenly you see that don’t they hear you? What if the situation repeats itself with all the apps that have access to this component? The cause may be a software malfunction or hardware damage.
Has your smartphone taken a hit recently? Has it gotten wet? Have you applied any updates recently? The causes for which this component of the terminal can fail are many and varied, but, fortunately, almost all of them have a solution like the ones that we are going to leave you below these lines. So we recommend that you do not stop paying attention if you want to repair the microphone of the mobile.
If the mobile has been wet or hit…
This is one of the main reasons why your phone microphone has stopped working . Luckily, newer smartphones are fairly waterproof, but you may have some liquid blocking the sound. To solve it, the most opportune thing is that you blow in all the openings of the terminal, including this component of the terminal.
If this doesn’t work, you can try letting it dry naturally, but as long as it’s not in direct sunlight. Since it could completely damage the device.
Although, we cannot ignore the possibility that it has been damaged due to a small blow that we have given it or because it has fallen from our hands.
Don’t put it in rice
The urban legend says that rice is capable of absorbing all the water that is in a smartphone that has gotten wet and, although it is not a lie, the reality is that the remains of the rice can reach places where they can cause more harm than good.
Instead of rice, you can use a ziplock bag and place your smartphone inside along with a couple of cotton balls, make-up remover wipes, or the classic silica or anti-humidity balls. If after leaving it for a few hours without using it, you verify that it has dried properly, but the microphone of the mobile does not work, it is most likely that this part will have to be repaired or replaced.
It has fallen
Another of the possible factors that have been able to leave us without this component of the terminal could be due to a blow, even if it was minimal, or an accidental fall. In these cases, the only alternative that we have within our reach is to go to an official technical support so that you can repair the microphone of the mobile. The main problem with this is that it will not be covered by the warranty , so we will have to be the ones who assume the responsibility of repairing the smartphone.
If nothing has happened…
If the microphone of the mobile has stopped working right away, it may be a hardware error, for which you must claim the manufacturer’s warranty and take the device to repair or, directly, change the smartphone. However, before you know it, you can perform a series of checks that can fix the failure of your Android.
do a reset
If you haven’t restarted your phone in a while, now is as good a time to do it as any. Restarting the mobile completely cleans the cache of the device, basically because it deletes all open applications and eliminates possible errors that appear after continuous and long use. This is the fastest solution to your problem as you simply have to turn off the smartphone and wait between 10 and 30 seconds before turning it on again. Later, we will have to check if the bug with the sound of the microphone has been solved.
removes dirt
Few of us are used to cleaning our mobile from time to time . The phone is one of the devices that accumulates the most dirt throughout its useful life because we carry it with us at all times, in our pocket or bag, and we leave it exposed to different external agents.
Although most phones already have protection against dust and dirt , the truth is that some are still vulnerable to these factors or small elements that can enter through the small openings of the phone. The microphone is a small hole that is usually located next to the USB connector and to clean it you can try to blow lightly into the hole or use a small pin without using much pressure to remove any foreign body that is causing the failure. Although, the best option will be to use a brush with soft and good quality bristles to remove the dirt that may have accumulated inside.
Do you have any headphones connected?
You may not remember, but surely you have connected a Bluetooth device to the phone that has its own microphone, be it a headset, a speaker, the car radio.
Therefore, make sure to disconnect other devices from the mobile. The quickest thing in this case will be to turn off Bluetooth directly if necessary, and restart the smartphone to see if it works fine again.
Watch out for updates
Taking OnePlus as an example, you can see how a simple system update can make the phone stop working specifically . When several smartphones of the brand were updated to OxygenOS 10.5.10, the microphone stopped working for almost all applications. You could make calls but it didn’t work for Google Assistant or WhatsApp voice memos.
If the problem has arisen after updating the mobile, you will have to wait for the brand to release a new patch that solves the error or go back to a previous version of the operating system. The easiest way to return to the original version that came on your Android phone will be to reset the device, something that we will explain later.
Is it a permissions problem?
If you find the problem only in certain applications, it may be that they do not have access to use the mobile’s microphone or, if they did, it has been revoked at some point.
You can check the applications that are using this component by going to the terminal Settings> Applications and notifications> Permission manager> Microphone permissions.
If the app you’re having trouble with isn’t among the allowed ones, you can add it from this panel.
Turn off noise reduction
Some versions of Android come with a cool feature called noise suppression/noise reduction . This feature is used to remove background noise when you are on a call or recording a video. However, this can be one of the causes of your phone’s microphone malfunctioning.
To disable this option open the Settings panel, select Call Settings, scroll to the Noise Reduction option and turn it off. Reboot the phone and check if the issue is resolved.
Have you installed anything recently?
Some apps may cause your phone to malfunction. Sometimes they can interfere with the microphone in the same way as with any other component of the smartphone and knowing it is as simple as starting the mobile in safe mode . To enter it, the easiest thing will be to go to the on/off menu and press and hold on the Restart option. After a few seconds it will ask us if we want to enter this mode when the terminal restarts.
This allows you to temporarily disable all third-party applications so, if when trying to make a call or use the recorder, you see that this component works fine, the problem is with an app that you have recently installed on the device.
Go deleting and reinstalling one by one the ones you have downloaded in recent days until you find the one that causes the error on your Android.
Restore the phone
Once again we reach the final point that awaits us every time we try to repair a mobile and we do not find the key. As you already know, returning the smartphone to its original state implies losing all the data stored in the memory, so you must first make a backup of all your photos, videos, apps and content that you save on the terminal.
After doing so, open the Settings panel, go to the System section > Reset options > select the Erase everything option. The mobile will turn off and on so you can configure it again and check if the microphone works again .
Take the terminal to repair
If after carrying out all the operations that we have proposed in these lines, you will have no choice but to execute the mobile warranty (if it is still valid) and take it for repair, as long as it was not due to a blow, fall or have wet.
If it is out of the protection period, you can take it to a brand workshop or a technical support specialized in phone repair and make sure that, if you have to replace the microphone, it is done with original spare parts so that you do not give trouble in the near future.
