Replacing the iPhone 13 screen disables Facebook ID

Apple reduced the notch size of the screen in the iPhone 13 series, but one of the changes it did not mention was that because the screen is connected to the Face ID system, if the screen is replaced by unapproved Apple repairmen, the face ID will be disabled. . This is happening now by IFixit website Also approved.

The component that causes this problem is a small chip that sits on the cable that connects the monitor to the motherboard. This chip did not exist before and there was no problem. But now only repairmen who are members of Apple’s repair program have access to tools that make it possible to accept a new display on the chip.

Unapproved by Apple repairmen, there is only one way to keep Face ID alive: separate the chip from the previous display and solder it back to the new display. But because this chip is so small, it will be very difficult to do. The image below shows the chip next to a grain of rice.

At the bottom you can see the same chip that is out of place. The chip junction is a network of points called the Ball Grid Array, which is used to connect complex chips to high junction points. Due to the small size of this chip, it will not be possible to solder it by hand.

A number of repair centers have developed tools and taught their repairmen how to do this, but their number is very limited. This process is a time-consuming and complex process that poses more challenges than ever before.

Some users still think that this problem is an unintended event and will be fixed in future iOS updates. Last year, a similar problem caused the iPhone 12 camera not to work when the lenses were moved, but Apple later fixed this problem with an update and activated the cameras.
