There are a lot of QR codes printed on the internal components of a device IPhone Your device and you can easily see it if you open the device (of course we do not recommend this). These barcodes or QR codes help Apple know more details about the origin of the iPhone’s components, but surprisingly, even the iPhone screen also contains On a hidden code, let's find out why Apple places a secret barcode on the iPhone screen?
Why does Apple put a secret barcode on the iPhone screen?
Since 2020 until now, Apple has placed two quick response codes (QR Code) on the iPhone screen, but what is the benefit of these codes for the company? The answer is that they help save a lot of money for Apple.
This bar code cannot be seen with the naked eye
The story began when Apple felt that its suppliers (Lens Technology and Bell Crystal) were deceiving it by hiding the real number of defective screens that were manufactured for the American company, and thus the iPhone maker incurs additional costs in exchange for producing a large number of screens for its iPhone devices, and this is why Apple decided Spending millions of dollars to add two barcodes to each iPhone to track how many units of the glass cover were produced by its suppliers.
According to the “The Information” website report, Apple has been using barcodes in iPhone devices for approximately 4 years, and the location of the QR codes has changed over time. For example, in the iPhone 12, the barcode was located above the front speaker, while in the models. Newer, the icons are located next to the bezel at the bottom edge of the screen.
Screen barcode development
The report also indicates that the process of developing this type of barcode was very difficult for Apple. Initially, the codes were laser-etched into the glass, but this eventually weakened the iPhone's screen and in drop tests, cracks in the glass often came from where the QR code was placed.
That's why Apple engineers had to invent new technologies using microscopic lenses with ring lights, and the result turned out to be positive. Since introducing these symbols (one is the size of a grain of sand and can only be seen using special tools, while the other is about the size of a pen tip), Apple suppliers have reduced the number of defective glass units to 10 in 3, compared to 10 in XNUMX. Previously cut.
Finally, Apple's keen attention to detail in manufacturing devices such as the iPhone is what drives it to search for any solutions to its problems. That's why it was able to reduce defective screens and prevent its suppliers from stealing them; Which helped her reduce the costs she incurred every year.

By God, Apple deserves respect and is more trusted than any company in the world, whether Eastern or Western. It has no equal in terms of credibility, attention, and respect for privacy.
There is no reason for concern or fear. All it has to do is that it is set to track the components of the device and the screen, and it does not carry any information related to the user. This is a smart move by Apple to limit the deception of the factories contracting with it 🌹
Welcome, Muhammad Al-Jaber 🌟, thank you for your constructive and useful comment. You are absolutely correct. The codes inside the iPhone do not contain any user-specific information, and are only for tracking components and the screen. This is one of the smart steps that Apple is taking to ensure the quality of its products and maintain its good reputation in the market 🍏. Indeed, Apple always proves that it is not only a company that makes electronic devices, but rather an artist in the world of technology! 🎨📱
May God’s peace, mercy, and blessings be upon you. I expect that this code allows hackers to spy on the iPhone, but is this code present in the iPhone 15?
May the peace, mercy, and blessings of God be upon you, Sultan Muhammad 🌹. Don't worry, this code does not allow hackers to spy on the iPhone, it is only designed to track components by Apple. As for the iPhone 15, we believe that Apple will continue to use this technology in its future devices. 😊📱💡
