Why Your iPhone Has a Hole Next to the Camera
You’ve probably noticed a tiny hole in your iPhone or iPad next to the camera. It’s not a design flaw and those aren’t extra sensors. Actually, that little hole is there for a microphone!
You see, when you are shooting video with the rear camera, these tiny microphones are necessary for capturing clear audio. Without them, the output would sound much less clear. So, Apple has placed these special microphones inside each hole to help out!
