I got an idea the other day when I was looking at my co-worker’s iPhone X sitting on a desk. I thought that I could have mistaken it for my own phone, since iPhone X comes in two colors and you have a 50% chance of having the same phone color as any other person. I was thinking that if I did mistake it as my phone and entered my passcode, I’d basically be transmitting the key to all of my personal data.

That led me to think about how hard it would be to reproduce the iPhone X’s lock screen and spoof one of my own. It turns out that with some experience with iOS development, it’s not that hard. Thanks to the iPhone X’s Super Retina display, a screen full of black pixels is indistinguishable from a device that’s asleep. And thanks to the omission of the home button, and a public API for disabling the swipe to go home gesture, I was able to make a pretty convincing copy of the iPhone X’s lock screen. Your mileage may vary if you’re trying to spoof other iPhone X models.
