Tiago Costa on Instagram: "If someone steals your iPhone, here’s the first thing they’ll try to do: swipe down the Control Center, turn on Airplane Mode, and then power off the phone—so you can’t track it. But here’s how to stop that from happening: Go to Settings > Face ID & Passcode, scroll down, and turn off Control Center access when locked. Now no one can access it from your lock screen. Next, go to Settings > [Your Name] > Find My > Find My iPhone, and make sure all options are turned ON.
