Specifically, in the video you can see that a person opens the control center of the iPhone by covering the front camera to prevent it from detecting the face. Then turn off mobile data, WiFi and Bluetooth. Once this is done, click on the airplane mode to activate it and leave the iPhone without any type of connection. When this is complete, you must allow the iPhone screen to rotate.

When you have done all this open the calculator from the shortcut that can be found in the control center. When you open it, rotate the mobile to have it in a horizontal position so that the scientific calculator options open. Once you are here you simply have to click on the decimal point, followed by the 'ln' button. If everything goes well, the calculator should throw an error that is eliminated with the 'Rad' button. When removing it, swipe up to have the iPhone fully unlocked.

Apple is already working on the solution

Without a doubt we are facing a security flaw of considerable importance since it leaves the iPhone totally unprotected. In a very simple way you can access all the information on the device without it being yours. What is really interesting is how convoluted the system that must be used is to be able to generate the problem that causes the bug to unlock the iPhone completely.

Although Apple is already aware of this security flaw and they are already working on them. In the tests that have been carried out in this writing in the iOS 14.6 beta, it is not allowed to rotate the calculator when the iPhone is locked, while in previous versions this does not happen with the possibility of accessing all the keys. This makes the solution closer to being a reality, although a priori it is possible that a 'cumulative' update will be released to resolve it before the arrival of iOS 14.6.

Although, another of the short-term solutions is to disable access to the control center when the iPhone is locked. This is achieved by following the path Settings > Face ID and code. Within these options, simply deactivating the option 'Allow access when blocked' in the control center, the security problem is solved.
