The Xiaomi Mi 9, which was released in 2019, is still popular due to its stylish design and performance. However, the glass back panel, which is part of the design, is extremely vulnerable to bumps and falls. When cracks appear on the body, the owner is asked about the cost of restoration. The price of repair depends on whether it is affected, only the external glass or the display matrix.
It's important to understand that in modern smartphones, including the Mi 9, the display module is often a single assembly. This means that the glass, touchscreen and matrix are glued together in the factory. Replacing only the glass requires specialized equipment and experience, whereas replacing the module assembly is a more common but expensive procedure. In this article, we will discuss pricing in detail so that you can make an informed decision.
The cost of the work varies depending on the region, the status of the service center and the quality of the components used. The average cost of replacing glass with Xiaomi Mi 9 in specialized workshops is from 2500 to 4500 rubles, which is much cheaper than replacing the entire display module. Self-repair without skills can lead to final failure of the device, so risk assessment is critical here.
Factors Affecting the Cost of Glass Replacement
The first thing to consider when calculating the repair budget is the type of damaged element. If only the exterior glass broke and the image remains clear, without stains and stripes, then you're in luck. OCA-It's a time-consuming process, but it retains the original matrix, which is often more profitable.
If the matrix is damaged (black spots appear, touchscreen is not working or the image is flickering), a complete replacement of the display module will be required. The cost of such a service for the Xiaomi Mi 9 will be much higher, since the matrix itself is the most expensive component of the smartphone. Original parts are expensive due to AMOLED technology and high screen resolution.
The final amount is also affected by the status of the service center: Official authorized centers use only certified components, which guarantees quality, but increases the check. Private workshops can offer lower prices using analogues or refurbished modules. It is important to specify which component will be installed: the original, copy or OEM-analogue.
Price comparison: service center or self-repair
When considering repair options, many users try to save money by ordering parts on marketplaces. Indeed, buying glass or a module separately may seem cheaper. However, the Xiaomi Mi 9 is characterized by a complex design with adhesive support and moisture protection. Self-replacement requires the purchase of special glue, opening tools and skills with micro soldering or separator.
Service centers charge not only for the part, but also for the guarantee. If you repair yourself, you risk damaging the plumes, breaking the matrix when you remove old glass or breaking the seal of the case. In a professional workshop, you will be provided with a check and a warranty card. If there are defects during the warranty period, repairs will be carried out free of charge.
Below is a table showing the approximate price range for repair services for display group and glass for the Mi 9 model in the current season.
| Type of service | Cost of spare part (ruble) | Cost of work (ruble) | Total (roughly) |
|---|---|---|---|
| Glass replacement (lamination) | 1000 - 1500 | 1500 - 2500 | 2500 - 4000 |

💡
When ordering a service in the service, always require a preliminary defect. The wizard should show you whether the touchscreen and matrix are working before starting disassembling the phone.
Why replacing only glass is more profitable
Many owners of Xiaomi Mi 9 do not know that you can replace only broken glass, retaining the factory matrix. AMOLED-When replacing the module in the assembly (especially for cheap copies), color calibration and viewing angle often suffer. Keeping the native matrix through the lamination procedure allows you to keep the image quality at the same level.
The process of replacing glass takes longer than simply replacing a module: the wizard needs to heat the case, separate the glass with a special machine, clean the adhesive base and paste new glass under vacuum. Despite the complexity, the final cost is often lower than buying a new original display module.
⚠️ Warning: Don't try to unstick the glass with a hairdryer yourself at home. Overheating can damage the battery or cause the matrix to burn out, turning a simple glass repair into an expensive replacement for the entire screen.
In addition, changing the glass allows you to maintain the factory moisture protection (at least partially), if the master uses a quality B-7000 or a special sealant. When installing cheap copies of modules, the tightness is often completely violated.
Risks of self-replacement of glass
When you decide to make a self-repair, you take all the risks. Xiaomi Mi 9 has a glass back cover that attaches to a powerful layer of glue. To get to the internal components or display, often requires heating and the use of suction cups. Inexperienced user can crush the lid permanently or damage the internal plumes.
One of the biggest problems is dust, because if you replace glass in unsterile conditions, microscopic dust or villi can get between the layers of the display, and you can't remove them after gluing them, and they will horn your eyes all the time you use the phone, and professionals work in laminator chambers where there's no dust.
☑️ Checklist before going to the service
Another risk is the use of poor-quality glue: Cheap analogues can turn yellow over time, peel off or even release harmful substances. In addition, the wrong dosage of glue can cause the phone to stop holding charging or lose the network signal due to pressure on internal antennas.

How to Choose a Reliable Service Center
Choosing an artist is half the success. Don't chase the lowest price in the ads of "private owners." A reliable service center always provides a guarantee for the work done and parts. For the Xiaomi Mi 9, it is important to find craftsmen who have experience with this model, since the design of the case has its own nuances.
Pay attention to the equipment. To replace glass properly, you need a separator, a laminator, a vacuum chamber and ultraviolet dryer. If the master suggests doing it on the knee with a hair dryer, you should decline this service. Also, it is a good form to be present at the repair or have access to video surveillance.
Ask about the origin of the parts. An honest craftsman will tell you if he's putting the original, the quality copy or the refurbished module.Secrecy is a wake-up call. It's also helpful to read reviews about a particular specialist or center on the Internet, paying attention to dates and details of comments.

The warranty for glass replacement is usually less than for a module replacement, and often does not cover mechanical damage after repair, but it should be mandatory.
