Find out what the little hole on the side of your cell phone is for

What is this hole and what is it for?

But if you look closely, you will observe that there is a discrepancy that usually goes unnoticed.

Just like there is a hole to remove NanoSIM and MicroSD slot, there is another one on top of the smartphone. But what is this strange hole in the Android smartphone for?

A mysterious location

To begin with, it differs from the NanoSIM and MicroSD slot because when you press it with the key or stick in the box, no tray comes out. Phones usually have a hole in the bottom, near the charging port where the microphone is.

If you imagined that the speaker also had the specificity that it acts as a microphone, you were wrong. Android phones also have another hole in the top, very similar to the bottom. Well, it’s another microphone too, and the special thing about this hole is that it’s responsible for limiting or canceling the noise coming from outside or from your environment. Then your calls become so clear and you hear e.g. not what happens on a construction site or traffic noise. It’s really very practical.
