That Tiny Hole Next To Your Phone Camera Isn't A Sensor

You've stared at it a thousand times and guessed wrong every single time.

Look at the back of your phone near the camera. See that little pinhole? Most people assume it's a light sensor. It isn't.

It's actually a microphone. Phones carry more than one, tucked into corners you never think about.

That second mic helps cancel background noise on calls. When wind or traffic roars, it quietly does the math.

So next time a call sounds crystal clear in chaos, thank the tiny hole you've been ignoring for years.
