Update for iOS 10.3.2
Apple still has not patched the hole allowing you to bypass the iPhone lock screen. As of iOS 10.3.2 (and the 10.3.3 beta), you can still trick Siri into getting into a person’s iPhone.
It works like this:
- Press the home button using a finger not associated with your fingerprint authentication, prompting Siri to wake up.
- Say to Siri: Cellular data.
Siri will then open the cellular data settings where you can turn off cellular data.
Anyone can do this—it doesn’t have to be the person who “trained” Siri.
By also turning off Wi-Fi, you cut off her connectivity access. You will get an error saying, “Siri not available. You are not connected to the internet.” But you don’t care about that error because you have already bypassed the iPhone lock screen.
