Owners of the popular Xiaomi Mi 9T smartphone often face an unpleasant situation when the screen cover gets damaged. Falling from a small height or careless movement can lead to cracks that not only spoil the appearance, but also interfere with the comfortable operation of the device. The issue of the cost of recovery becomes relevant immediately after the incident, since the type of damage directly depends on the price of repair.
Now, you have to understand that changing the glass and replacing the display module are two fundamentally different procedures, and they have a significant difference in price. In modern smartphones, including the Redmi K20 (the global version of the Mi 9T), the screen is a multi-layered structure where the glass is tightly glued to the matrix, and it's the complexity of separating these layers that affects the total amount you're going to hear in the service center.
In this article, we will discuss in detail what the cost of repairs is, why prices can vary several times and what is more profitable: change only the glass or the entire module assembled. You will also learn about the risks of self-repair and get up-to-date data on the prices for services of masters.
⚠️ Warning: Operating a smartphone with cracked glass can lead to further destruction of the matrix.Splinters put pressure on the display, and even a light press can finish off the desktop screen, turning a simple glass repair into an expensive module replacement.
Factors affecting the cost of repair Xiaomi Mi 9T
The price of the Xiaomi Mi 9T screen repair is not fixed and depends on many variables. The first and foremost factor is the degree of damage. If only the top security glass is broken, and the image remains bright, without spots and stripes, then it is a budget option for repair. However, if the matrix is affected, the cost will increase by 2-3 times, since you have to change the entire knot.
The second important aspect is the quality of the components used. In the Xiaomi smartphone parts market, there is a gradation in quality: original parts (Original), high-quality copies (High Copy) and budget counterparts. Original glass with an oleophobic coating will provide the same sensitivity and color reproduction as factory glass, while cheap counterparts can distort colors or react less to touch.
The price is also affected by the service center policy: Official authorized centers often charge more for work, but give a guarantee and use certified materials. Private workshops can offer a lower price, but here it is important to make sure that the master is qualified, since the Mi 9T has a complex design with a retractable camera, requiring careful disassembly.
- 💰 Type of damage: glass or matrix only + glass.
- 🏷️ Quality of spare parts: original, OEM budgetary.
- 🛠️ Master’s qualifications and level of service center.
- 📍 Region of work and pricing policy of the city.
Replacement of glass or display module: what is the difference?
Many users confuse these concepts, believing that the screen is a single unit. In fact, the display module Xiaomi Mi 9T consists of a touchscreen (touch layer), matrix (indicates image) and protective glass. In factory assembly, these components are soldered or glued into a single unit. Replacing the module involves installing a new unit as a whole, which is faster, but much more expensive.
Replacing only glass is a more delicate job, requiring special equipment. The wizard needs to separate the broken glass from the entire matrix using a separator (heat) and a string. After that, a new glass is glued to a new matrix or old one (if it is intact) in the vacuum chamber to avoid bubbles. It is the presence of lamination and re-adhesive equipment that makes this service available not in every service.
If you have broken glass, but the image is perfect, replacing only the glass is an economically viable step. You only pay for the work of the master and the cost of glass, saving up to 60% of the price of the new module. However, if the screen appears black spots, stripes or it stopped responding to touch, replacing the glass will not help — you will need a complete replacement of the module.
Why can’t you make the glass at home?
⚠️ Attention: Don't try to heat the screen with a hair dryer and tear the glass off with a blade yourself.The Matrix in Mi 9T It's very thin and sensitive to overheating, and there's a high risk of damage to the plumes or the matrix itself, and then repairs will be impossible.
The current price list for screen repair Mi 9T
The cost of screen repair can vary depending on the region and the service chosen. Below is a table with the approximate prices for repair services Xiaomi Mi 9T at the moment. Prices are indicated in rubles and can vary depending on the exchange rate and logistics costs.
| Type of service | Quality of spare parts | Average cost (ruble) | Time limit for implementation |
|---|---|---|---|
| Replacement of protective glass | Original (copy) | 2 500 – 3 500 | 2-4 hours |
| Module replacement (screen + glass) | OEM (quality copy) | 4 500 – 6 000 | 30-60 minutes. |
| Module replacement (screen + glass) | Original (Service Pack) | 7 000 – 9 500 | 1-2 days (on order) |
| Diagnostics | - | 0 – 500 | 15-30 minute |
As you can see from the table, changing glass is much cheaper, but it takes more time to complete the work. The module is replaced faster, because the master does not need to carry out complex operations to separate the layers, just replace the unit. When choosing an original spare part, the price can be comparable to half the cost of the smartphone itself, which makes owners think about the feasibility of repair.
It’s also worth considering that in some cases, services may offer “repair repairs” when you change the glass to a used matrix, which is a risky option, since the resource of the old matrix is unknown. It is better to choose proven services that give a guarantee for their work and used materials at least for the first time. 3-6 months.
☑️ How to check the quality of repairs before paying
Can you save money: self-replacement or used spare parts?
The desire to save is understandable, and many are considering buying a spare part on marketplaces and self-installation. For the Xiaomi Mi 9T, this is possible, but requires the availability of tools: suction cups, mediators, heat dryer (or heating pad) and a special glue B-7000 or T-7000. However, without experience, you risk damaging the plumes or back cover, which in this model is also glass and easily beats.
Another option to save money is to buy a used module or screen with a broken back cover (donor), and you can find these offers on forums and ads. OLED-screens installed in Mi 9T, They burn out over time, may have a residual image (burn-in) or microcracks that are invisible when the screen is turned off.
If you decide to order parts yourself, look for the Mi 9T or Redmi K20 markings, as they are the same model. Also pay attention to the color of the plume and the location of the speakers holes. The wrong module may simply not fit into the case or jam with the board.
💡
When buying a screen on AliExpress or other sites, always ask the seller to send a photo of the screen on white and black background, which will help to identify broken pixels and uneven backlights before buying.
Technical features of the screen Xiaomi Mi 9T
Xiaomi Mi screen 9T technologized AMOLED permittingly 2340×1080 This means that each pixel glows on its own, providing deep black and high contrast. AMOLED-Matrices are less mechanically strong than IPS, And when you hit, cracks often go spider webs all over the surface.
An important feature is the built-in fingerprint scanner. When replacing a module or glass, you need to calibrate the sensor, although in most cases, after replacing the original or high-quality compatible module, the scanner starts working immediately. If you change only the glass, the wizard must be extremely careful not to damage the layer that reads the fingerprint.
Also worth mentioning is the screen frame, which is quite thin in the Mi 9T, which increases the risk of damage when falling on the edge. When installing a new module, it is important to check the density of the fit so that moisture and dust do not get inside, which can quickly disable electronics.
- 📱 Type of matrix: AMOLED, Samsung or Tianma production.
- 🖐️ Fingerprint scanner: optical, subscreen.
- 🛡️ The Corning Gorilla Glass 5.
- 🎨 Color rendering: support HDR10 and wide color coverage.
⚠️ Note: After changing the screen to AMOLED-It's not recommended to immediately set the maximum brightness. Let the new screen warm up and adapt for a few hours of operation in normal mode.
Warranty and Risks: What You Need to Know Before Renovation
When contacting the service, always specify the warranty conditions. The replacement of glass warranty is usually less than (1-3 months), as it is fine work, and the risk of re-breaking is higher. The replacement module warranty can reach 6-12 months. Be sure to require a check or a certificate of work performed with the serial number of the device or a note about the operation performed.
One of the risks is that you lose waterproofing. The Xiaomi Mi 9T factory assembly uses adhesives to protect you from splashes. When you repair, even in good service, the airtightness is broken, so you don't have to test your phone for waterproofing after you've repaired it.
Another important thing is the software, and in rare cases, when you change the screen, you may need to flash or calibrate through the engineering menu, and make sure that the wizard has the skills or access to the right software if the touchscreen doesn't work properly after you change it.
💡
The main criterion for choosing a service is not the lowest price, but the availability of own equipment for gluing glass and a transparent guarantee for the work performed.
