Many people cannot think without their smartphone from waking up in the morning to going to sleep at night. Whether for work or for entertainment, we spend the whole day using smartphones. But there are many things in this smartphone of Sadh, which are unknown to many people. There are many parts of mobile phones that people don’t know about. One of them is a small hole near the phone’s camera setup. Did you immediately turn your phone upside down? There is no reason why all phones will have this hole.
Most phones have this hole…
But you will find this hole in most of the phones these days. Often there is a small hole behind the rear camera of the smartphone. This hole may be slightly smaller or larger in different models. Do you know why the company gave this hole and what it does? Many people think that it is used for the design. But not at all. If you know the reason, you will buy the phone only if you see such holes later. Let’s find out.
What is the function of the small hole?
This small hole on the back of the smartphone is provided for noise cancellation. It is actually a microphone. That is, when you talk to someone on the smartphone, this microphone reduces the noise coming from around you. This means that whenever you talk to someone on the phone, your voice clearly reaches the other person. At the bottom of the smartphone where the charger point is, there is also a microphone, through which your clear voice reaches the person on the other side of the phone. The noise cancellation microphone on the back works to completely reduce background noise. But most of the flagship phones can see this feature. All phones have a microphone near the charger point.
