Smartphone Tiny Hole: Did you know that the tiny hole next to your phone’s charging port isn’t just a random design element? Many people mistake it for a reset button or an extra microphone, but it actually serves an important purpose. It's not for cosmetic flair or for venting steam. That tiny hole exists by design, and its role matters a lot more than you think. Some mistake it for the SIM ejection hole. But this is elsewhere and requires a tool or pin.
