The secret hole in everyone's phone, but almost no one knows its purpose and without it your phone is worthless

Mobile phone designs are constantly changing and vary greatly from brand to brand. From the camera module to the placement of buttons, including the hole in the screen, every detail has a basic function that makes it more practical and functional.

But there is one element that you may not have noticed or paid attention to before: the small hole present in all mobile phones, whether it is an iPhone, Samsung or Google Pixel. Although it goes unnoticed, its function is very important.

- The secret of the small hole in the mobile phone: What is its purpose?

If you take a look at the bottom of your phone, next to the charging port and near the speaker, you will see a small hole that at first glance may seem like part of the design or just decoration. However, it performs an essential function that ensures that your mobile phone is as useful as you know it to be.

This is the secondary microphone and is specifically designed to improve the sound quality during calls. It works by reducing background noise that might interfere with your voice.

This means that the person on the other end of the line can hear you more clearly, even if you're in a noisy environment, like a street with lots of cars or a place with music playing. Without this microphone, talking on the phone would be much more complicated and noisy.

The location of the hole at the bottom of the phone makes sense. Being close to your mouth means that sound pickup is more direct and clear, which translates to better sound quality during calls and recordings.

In addition, this mode helps to reduce ambient noise, as the microphone is better protected from external noise. In this way, although this small hole is not noticeable, the truth is that without it, the functions of your mobile phone would be very limited.

You won't be able to enjoy clear calls, record videos with sound, or even voice recognition in assistants like Siri or Google Assistant. These built-in microphones are an essential part of the experience that smartphones provide us on a daily basis.
