How Does Your Phone Know You're Standing Still?

Imagine your phone is like a little detective watching you. It uses special tools, called sensors, to tell if you’re moving or still. When you walk, it knows; when you stand still, it notices too. These tools are like tiny helpers inside the phone that work together so your screen can turn on only when needed and stay on while you read a message.
