You must be clicking pictures and selfies on a daily basis but have you ever noticed the tiny black hole between the camera and the flash?

Here is the answer.

The tiny black hole is a microphone but it will not pick up your voice. Its function is to cut off the microphone noise and remove the background noises while you talk to the other person on call. It provides more clarity to your voice.

It also helps Siri (a built-in ‘intelligent assistant’ that enables users of iPhone to speak natural language voice commands in order to operate the mobile device and its apps) to understand accents, improves Facetime and conference calls. It also helps in clicking pictures by eliminating pixel noise.
