A broken display is one of the most common and unpleasant problems faced by Xiaomi smartphone owners. The moment the glass cracks and the image begins to distort or disappear, the user faces a pressing financial question. The cost of replacing can vary widely, and often the price range is puzzled: why in one place they charge 3,000 rubles and in another – 8 thousand for the same model. Understanding the pricing structure will help you not overpay and avoid fraud.
The price is not only the cost of the spare part itself, but also the quality of the materials used, the complexity of disassembling a particular device and the skill of the craftsman. In some cases, it is cheaper to buy a new phone than to repair an old one, especially if it is a budget model, it is important to immediately assess the condition of the device and make an informed decision based on facts, not emotions.
In this article, we will discuss in detail what the total sum is, what types of matrices exist, and why the original part is always more expensive than the analogue, you will learn what you can save on, and where you can not save, and we will also discuss the topic of self-repair and explain why calibrating the touchscreen after replacement can be a decisive factor in quality.
What is the final cost of repair
The final price is generated in a service center or from a private master using a transparent but multi-component formula: the first and most important component is the cost of the display module itself. Smartphone manufacturers, including Redmi and POCO, use different panel technologies, and the price can vary significantly even within the same model range.
The second component is the complexity of the case design: Flagship models often have curved screen edges or glued structure, where the glass and matrix are soldered in the factory, disassembling such devices requires special equipment, heating and high skill, which directly affects the cost of work, while replacing glass on a budgetary framed device takes 15 minutes.
The third factor is warranty policy: Xiaomi’s official service centers provide a guarantee for work and parts, which is included in the price; private workshops can offer lower prices, but often operate without formal contracts, transferring risks to the customer. Below is a table showing the approximate ratio of the cost of parts for different classes of devices.
| Class of device | Type of matrix | Approximate cost of module (ruble) | Difficulty replacing |
|---|---|---|---|
| Budget (Redmi 9/10/12) | LCD IPS | 1500 - 2500 | Low. |
| Medium (Redmi Note 11/12/13) | AMOLED | 3500 - 6000 | Medium |
| Flagship (Xiaomi 12/13/14) | AMOLED 120Hz | 8000 - 15000+ | Tall. |
Keep in mind that fluctuate components fluctuate depending on the exchange rate and logistics chains. Original parts will always cost more because they are controlled by the vendor. Copies can cost two to three times less, but their resource and color reproduction often leave much to be desired.
Difference between original, copy and glued glass
When you come to a service, you're almost always offered a choice between "original" and "analogue." But the parts market is much more diverse. The original is often understood as a module taken from another phone (donor) or manufactured on the same line as the Xiaomi factory, which has perfect color reproduction, proper proximity sensor and fingerprint scanner.
Copies fall into several categories of quality. OLED" or "Soft" OLED" — These are matrices that try to mimic the original. They may have the right colors, but they're often less bright or have thicker frames. LCD-matrices installed instead of AMOLED. Visually, the phone works, but the Always On Display feature and the in-screen fingerprint scanner won’t work.
⚠️ Attention: When installed LCD-screen-in AMOLED In models where the fingerprint scanner is built into the display, the finger unlock function will stop working forever.
The third option is glass reglazing, and if your matrix is intact and only the outer glass is broken, some workshops suggest replacing only the glass, which requires factory equipment for vacuum gluing, and the quality of this repair is high, because the matrix remains native, but the risk of damaging the matrix in the process is great, so not all services take this job.
The choice between these options depends on your plans for the device. If you plan to use the phone for another year or two, it is better to look for an original module or a quality one. OLED-If the phone is being prepared for sale or use as a navigator, a budget copy will do.

Factors affecting the price in different services
Why is it 2,000 rubles in a subway and 5,000 rubles in a mall? Location and business format dictate their rules. Large network services pay rent, taxes, salaries, and maintenance of a spare parts warehouse, which guarantees you a check, a contract and the ability to make a claim, but the price will be higher.
Private craftsmen working from home or in small stalls often pay no taxes and rent, so their prices are lower, but in the case of marriage, it may not be possible to find such a craftsman in a month, and private workers rarely have a choice of parts: they put what the supplier brought today.
The frame is important. The framed module is more expensive, but it's easier and more reliable to install. The adhesive in the factory frame is already applied, and the wizard only needs to rearrange the insides. If you take a frameless module, the wizard will have to carefully clean the old adhesive and apply a new one, which increases the risk of dust falling under the glass or skewing the elements.
- 📍 Geography: In the center of Moscow or St. Petersburg, rents are higher than in the regions, which affects the final check.
- 🛠 Equipment: Services with separators and laminators can offer glass gluing, which is cheaper than replacing a module, but takes time.
- 📦 Availability of spare parts: Urgent ordering of rare parts for a specific model can cost more because of logistics.
Don't chase the lowest price, because the cheapest parts are often the lowest quality parts that fail in a month, and the best repairs can't cost a penny, because good matrices are getting more expensive every year.
💡
Always ask if it's a cost to replace the frame, and if the frame is curved or warped, the new screen may lie down with a gap or unstuck in a week.
Self-substitution: is the game worth the candle
Many users, when they learn the cost of a spare part on Chinese sites, think about self-repair. Indeed, on AliExpress, a module can cost one and a half to two times less than in a service with work, but there are hidden risks that are not written about in the reviews of sellers.
The first problem is the tool. To do a good job of disassembling, you need suction cups, mediators, screwdrivers, thermophene (or heating pad) and adhesive B-7000 or T-7000. Buying this whole kit eats up a lot of the savings. The second problem is the fragility of the plumes. Inexperienced movement can damage the main camera plume or the charging port, which is often under the screen.
Procedure for replacement:
1. Turn off the device.
2. Heat the perimeter of the body to 80-90 degrees.
3. Gently peel the glass off with a suction cup.
4 Unscrew the screws of the protective plate.
5. Disable battery and display plumes.
6 Replace the module and assemble in reverse order.The third risk is calibration. After installing the new screen, the sensor may need to be engineered calibrated, especially on models with a refresh rate of 120 Hz. Without special software and knowledge, the phone can "glut", incorrectly respond to touches or have brightness problems.
⚠️ Attention: Opening the case of a smartphone almost always leads to loss of water protection. IP68 no longer guaranteed.
If you don't have experience in electronics repair, you don't have to risk it. The cost of re-repairing after a failed "do-it-yourself" attempt often exceeds the cost of an initial professional replacement. The complexity of disassembling modern smartphones is high because of the dense layout and the use of a lot of glue.

Specifics of repair AMOLED and curved screens
Modern Xiaomi models, especially the Mi series and the flagship Redmi Note, are equipped with AMOLED-It's a technology where each pixel glows independently, and these screens give you deep black and high contrast, but they're extremely fragile. Mechanical damage to the outer glass causes 95% of the time to fail the matrix itself.
Of particular difficulty are curved-edged screens (2.5D or more) in which the glass and matrix are glued over the entire area, including the curved sidewalls. Only glass cannot be replaced at home, using a separator (separates the glass and matrix with a laser or string) and a laminator (glues new glass under vacuum).
The cost of these works is high, not only because of the cost of the equipment, but also because of the risk. If you reglaze the glass matrix can be damaged, and then the master will have to compensate you for the cost of a new module, so many services simply change the module assembly without taking up the gluing.
- 🔥 Thermal sensitivity: AMOLED-screens are afraid of overheating, so when disassembling, you can not warm the body for a long time above 90 degrees.
- 💧 Moisture: Moisture falling under the curved edge of the screen often causes colored spots to appear, which grow over time.
- 🔋 Energy consumption: Quality AMOLED Saves charge, while cheap copies can plant the battery faster than the original.
When buying a phone with a curved screen, you should immediately consider buying a quality protective glass or hydrogel film, which can cost up to 50% of the price of a new device, making repairs economically inefficient.
💡
For the curved AMOLED-Replacement of the module in the assembly is the only reliable way to restore the screens, ensuring tightness and proper operation of the touch.
