The production of technological devices takes a long long time. The device first gets designed in a digital environment, then gets prototyped and finally goes to test before the final market release. During this process, some measures need to be taken so that the design of the phone doesn’t get leaked by a spy or a foolish employee. ¹
If you look at the leaked images, there is an intense effort to prevent the iPhone’s design from leaks. The cases for the prototype devices are covering almost all of the phone. It looks like the rear part is completely closed, but there’s only a very small opening in the camera part. When we look at the front, we can see that all the details are completely hidden including the front camera, speaker, and home key button, or whatever Apple wanted to place there.
Even a very large portion of the screen is covered with black tape. There are yellow bands on the right and left side of the screen. If you want to remove the case, this part gets damaged and leakage attempts can be immediately recognized. In this way, iPhone securely gets delivered from China to the United States of America.
Each prototype has its very own unique passport, and these passports contain information about the device test results. Also, thanks to the QR code and GPS on the back, Apple can track where the devices are and get more details on the prototype.
Despite all this struggle, the measures are inadequate if we think that the iPhone 7 Plus is infiltrated six months before the release. At least we now know how the iPhone tries to protect itself from leaks.
