However, after our tests, most of them have been unworkable so far. Only one can magically help bypass iPhone screen lock. Here are details for you to refer.

1.1 Exact Steps to Unlock iPhone through Calculator

In the actual test scenario, we use iPhone 13 running on iOS 17.2.1 to successfully bypass screen lock (unlocking failures for iPhone 8 running iOS 16.7.2 and iPhone 6 running iOS 12.5.7). Here we show the complete operations for you to follow. This worked on an iPhone that tester actually doesn't have both Face ID and passcode to unlock.

1.2 Fail to Unlock iPhone with Calculator? Try to Fix!

Through our test, this solution is proved to be feasible. However, the success rate cannot be guaranteed. If you fail to unlock your iPhone using Calculator app, you can try the following workarounds. That's what we've done ourselves after several unlocking failures and luckily all of them are effective. However, what the result is going to be will still be influenced by a lot of uncertainty, like the iPhone model, iOS version, device status, etc.

  • Workaround 1: Change device language by tapping on Settings → General → Language & Region. (In the test, we changed it from English to Chinese)
  • Workaround 2: Power off your iPhone and wait for a while to restart it.
  • Workaround 3: Update the iOS version to the latest one by clicking Settings → General → Software Update.

1.3 Does Calculator Trick Actually Use Face ID to Unlock iPhone?

In the course of information collection, we found posts suggesting that the Calculator trick used to unlock the iPhone is a hoax. The reason it works is because when you swipe down or up on the locked screen, the iPhone camera automatically detects and recognizes the Face and uses Face ID to unlock the device. But in our practical operation, this statement remains to be examined. Because in our successful cases, the tester did not use his own phone and never enrolled personal facial ID to the tested iPhone.
