Smartphones know where you are like a detective knows who did it. They use clues from GPS satellites, your phone’s Wi-Fi connections, and the nearby cell towers to figure out where you are, even if you don’t tell them. It's like having invisible friends helping you find your way.
Examples
- Your phone knows you’re at school because the Wi-Fi there is familiar to it.
- Even if your GPS is weak, your phone can tell where you are by checking nearby cell towers.
