Very often, smartphone owners face a problem when the microphone on the phone does not work or works very poorly. There are actually several reasons why this happens, ranging from a banal software failure to a hardware failure. Actually, this will be discussed in our article. Also, the question of why the microphone on the headphones does not work, which is also a fairly common problem, will be additionally considered. In general, it will be interesting!
Software failure
The first reason why the microphone on the phone does not work is a malfunction of the operating system. It doesn't matter what OS is installed on the device - Android, iOS, Windows or any other, failures happen everywhere and they happen spontaneously.
How can I deal with a malfunction? There are severaloptions, and the easiest is to reboot the device. As a rule, in most cases, this completely eliminates the malfunction, and the microphone begins to function again. The second option is more radical - factory reset. Sometimes a software glitch can be much more serious than it might seem at first glance, and a simple reboot will not fix it.
Dust and dirt
The next reason why the microphone on the phone may not work well is dust and dirt. The holes for the microphone on the body of your device are quite small and often clogged with small dust particles and dirt particles. As a result of this, the sensitivity of the microphone is significantly reduced, and with very strong pollution, it almost completely disappears.
This problem is fixed quite easily:
- First you need to try to blow the microphone with air. You can try to blow on your own or use a can of compressed air.
- This may not always work, as dust and dirt particles can accumulate quite strongly. In this case, you will have to use a thin needle (or any other thin object). It should easily penetrate the opening of the microphone, 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, not pushing the needle too deep, otherwise there is a risk of damaging the microphone itself.
Bad contact
Oddly enough, falling smartphones also often becomethe 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 lame.
Actually, what is the danger for the microphone of the fall of the device? Everything is simple. If dropped, there is a risk that the microphone cable, which is connected to the main board, may break contact or completely disconnect from its connector. As a result, the microphone will either work with serious interference, or it will completely stop.
There is only one way to fix this problem. You need to disassemble the device and connect the cable to its place. You can do it yourself or take the device in for repair.
Moisture ingress
Moisture is also becoming a common reason why the microphone on the phone does not work. It’s not even worth explaining here how moisture gets inside: wet hands, using the device in the rain, in the shower, bath, sauna, etc. If it gets inside, moisture can not only disrupt the operation of the microphone, but even completely disable it. The only way to fix this problem is to replace the microphone with a new one.
Microphone failure
And, finally, the last reason why the microphone on the phone does not work is the malfunction of the “micro” itself. It often happens that for no apparent reason, the microphone simply breaks. Of course, sometimes a factor for a breakdown can be a marriage duringproduction, but, as practice shows, absolutely correctly assembled microphones also break.
The way to fix the problem here is exactly the same as above - a complete replacement of the defective part with a new one.
Microphone on headphones
Well, as a bonus, it's worth saying a few words about why the headphone microphone on the phone does not work. This is a fairly common problem, which, in turn, is divided into two:
- The first reason why the microphone on the headset does not work is a banal malfunction of the microphone itself or the 3.5 mm input on the phone. The easiest way to check if this is the case is on another device.
- The second reason is that the sensitivity of the microphone through the headset is set to almost 0. Such a malfunction occurs very rarely and is corrected through the engineering menu.
The access codes for the latter must be looked for under a specific model, since they are all different. Once in the engineering menu, go to the Hardware tab and select the Earphones and Mic item there (the name may differ).
The Speech Enhancement item is responsible for setting the sensitivity. You need to experiment with the parameters and find the necessary values at which the microphone on the headphones will start to function. It's also a good idea to write down the original settings in the menu in case something goes wrong.
