10 iPhone Security Settings You Should Change

Disable Control Center on Lock Screen

An easy way for thieves to prevent the iPhone they just stole from being tracked is to disable the GPS, which can easily be done by bringing up Control Center and toggling off the GPS, as well as cellular and WiFi.

However, thieves can't do this if Control Center is disabled on the lock screen. To disable it, go into Settings and select Control Center. From there, turn off the toggle switch next to Access on Lock Screen.
