The current situation in the service market dictates its conditions, and the price of glass restoration can vary depending on the region, the level of the workshop and the quality of consumables used. It is important to understand that the Xiaomi Mi 9 is equipped with curved glass at the edges, which greatly complicates the process of removing and installing a new layer compared to flat screens. This technological feature often becomes a decisive factor in the formation of the final amount of the check in the service center.
In this article, we will discuss in detail what the cost of repairs is, why it is so important to choose the right workshop and whether it is worth taking up this procedure yourself without specialized equipment.

Factors Affecting the Cost of Repair
The first thing to consider when calculating the budget is the degree of damage to the display unit. If the matrix is intact, the image has no stains, stripes or broken pixels, and the sensor responds throughout the area, it is called glass gluing, which is a more budget option, but requires a high skill master and the presence of a separator to carefully separate the layers.

Difference Between Glass Replacement and Display Module
Many users mistakenly believe that the screen is a monolithic part that can only be replaced in its entirety. In fact, a modern smartphone display consists of several layers: a protective glass, a touch screen (touch layer), and the matrix itself, which is responsible for the output of the image. Only the top layer (glass) can be replaced only if the underlying components are completely serviceable.
The process of replacing the module is much simpler and faster: the wizard simply turns off the train of the old screen, installs a new one and sticks it to the frame, in which case you get an essentially new screen with a perfect image and a factory oleophobic coating, and the cost is high, but it ensures that there are no color reproduction and sensitivity problems in the future.

Another risk is damage to the fingerprint scanner built into the screen, which is that when you get too hot or pressurized during glass change, you can disrupt the calibration or physically damage the sensitive element, and then the finger unlock function will stop working, and software can often not restore this function without authorized hardware.
- 🔥 Overheating: Local overheating when glass is unplugged can cause battery bloating or plumes to detach.
- 🔌 Footage: Thin plumes of the display and touch screen are easy to break with careless handling of the tool.
