iPhone: This is the black dot next to the camera

The newest iPhone generations have a mysterious black dot next to the camera. Behind it is one of the most practical functions of the iPhone, which most users are unaware of. We solve the puzzle about the black dot.

iPhone: That's why there's the black dot next to the camera

Turn your iPhone over and look closely at the black dot between the camera lens and the flash. You will find that this is actually a small hole. This is somewhat reminiscent of the reset buttons on routers and other devices.

• But the small point is not a reset button. Rather, it hides a small microphone that fulfills two important tasks.
• When you use your iPhone to make a call, the cell phone uses the small microphone on the back to pick up the ambient noise from your surroundings and then filter it out. This creates a much better sound for both you and your conversation partner.
• However, if you record a video or speak to Siri, the small microphone next to the camera works with the microphones on the bottom and front of the iPhone. All three microphones record the sounds from different directions and thus produce an even better sound.

There are many other small functions hidden in the iPhone that almost always go under. On the next page, we will clarify what the blue dot in front of individual iPhone apps is all about.
