Have you ever wondered why your iPhone has a tiny hole next to the camera? Well, next time you have your phone on you take a look and see if you can guess what that tiny hole is.
There's no reason to be alarmed. The tiny hole is not a hidden camera, but is actually one of the three microphones on Apple’s iPhones. The iPhone has three microphones in total. The main microphone is located at the bottom of your phone where you talk into. Then there’s a hidden one beneath the iPhone’s speaker grill and finally there’s the tiny microphone located between the camera and flash on the back of an iPhone.
The tiny microphone serves mostly for analyzing and removing background noise during phone and FaceTime calls or when recording your voice on the “voice memos” app. It helps SIRI with voice recognition as well. The microphone hidden beneath the iPhone's speaker grill is turned off during phone calls because the main microphone is used. Yet, the hidden microphone helps record great stereo audio when recording videos.
