Do you know why there is a tiny black hole between your iPhone camera and flash?

You may have been using an iPhone since its launch but there are some things about the Apple’s flagship product that you still don’t know about.  In fact, you might be calling yourself a pro in using and understanding iPhone, there are certain features on your iPhone that you may still not know. One such feature concerns the camera on your iPhone. Have you ever noticed a tiny black hole between your iPhone camera and flash?

Basically, every iPhone since the iPhone 5 has had a tiny black dot between the lens and flash. Have you ever wondered why it is there and what does it do?

This tiny hole is basically a microphone. Yeah, you read it right. Technically, it is not a microphone that would listen to your voice but this one is for noise cancellation. This microphone can eliminate background noises so that the caller on the other end hears only crystal clear voice. It also helps to record your voice without any filler and makes Siri’s recognition of your accent even better when recording HD videos.

The iPhone actually has three microphones, one at the bottom, one on the back and one at the front often hidden under the grill for the phone speaker, as it is not active during the normal phone conversation. The reason behind putting two microphones is for stereo output while recording videos, which gives better results while playing it on a stereo sound system.

Okay, iPhone has three microphones! Now, you may wonder why iPhone needs these three microphones. While the bottom and front ones are used for user’s own voice and hearing purpose, the one at the back is useful for video recording and for digitally removing background noise when you’re on a phone or FaceTime call. It also helps a little bit when clicking pictures, by eliminating pixel noise.

There you have it. The secret behind the secretive tiny hole on the back of an iPhone!
