Even if you use your smartphone on a daily basis, many individuals still don't have a good understanding of all of its functions. One of them is about a hole that is located close to the charging port on the smartphone. It's possible that a lot of people are unaware of what this hole is used for!

You are going to be astonished to learn that in the absence of this hole, you are unable to make or receive phone calls. Despite its apparent simplicity, this hole serves a variety of purposes.

What exactly is the point of having this hole here?

The charging port of the smartphone is located right next to this hole, which can be found at the bottom of the device. In reality, it is a noise-canceling microphone, the kind that is included in every modern smartphone. Because of this hole, you'll be able to make calls of a high quality. If you do not have it, the other person on the line will not be able to hear you as well as they should.

Because of the confinement of this room, it is feasible to achieve total silence regardless of the ambient noise. Even if there is a lot of background noise, you will still be able to hear the other person's voice on the call because of this hole. Even that particular individual can make out your voice quite clearly. Each and every smartphone comes equipped with this capability. It will be tough to have a conversation on the phone if a smartphone does not provide this feature.
