How Do Smartphones Know When You're Walking?

Smartphones have little helpers inside them called sensors that can feel how you move. One is like a tiny gyroscope, which helps the phone know when it's spinning, and another is an accelerometer, which tells it when you're speeding up or slowing down. Together, they work like a team to tell if you're walking, running, or even just sitting still. It’s like having a mini detective inside your phone that follows you everywhere.
