A broken smartphone screen is always an unpleasant surprise that knocks you off track and makes you look for urgent solutions. For owners of Xiaomi Redmi 9 with NFC, the situation is complicated by the fact that in this model the display module is a single design, where the glass, touchscreen and matrix are soldered together. That is why the question of the cost of repairs stands edged: do you change everything entirely or look for a master who will reglaze the glass?
In the current market, the prices of components and services of service centers vary widely, and the total amount is influenced by many factors, from the region of circulation and the status of the service center to the quality of the parts used. The original display will cost much more than a quality copy or a restored module, but ensures the preservation of all functions, including the operation of the NFC module and the brightness of the screen.
In this article, we will take a closer look at pricing in the service market, explain the difference between parts types, and help you make an informed decision, explain why spare parts savings can lead to the loss of important functions and how to properly prepare for a visit to the service.
What is the final cost of repair
The price you'll see on the price list is not just the cost of a piece of glass or plastic, but the price of a part that depends on currency and logistics. The situation for the Redmi 9 is very specific: original displays (OLEDs or quality IPS) are harder to find than copies, and they cost 40-60% more.
The second important component of the price is the complexity of the work of the master. Replacing glass on modern smartphones requires the use of a separator (a special machine for splitting glass and matrix) and a professional adhesive base LOCA. If the service offers you to simply glue the glass without removing the frame, this should be alert, since the tightness and uniformity of the fit will be violated.
Cheap garage shops often don’t make any commitments, while authorized centers include maintenance, seal checks and water protection (if it was declared by the manufacturer) in the price. It is important to understand that when replacing the entire display module in the assembly, the risk of damage to the internal components of the smartphone is minimized, which also justify the higher cost.
Price difference: original, copy and refurbished module
Xiaomi’s parts market is full of offerings, and it’s easy for a beginner to get confused in terms. Original is a detail identical to the one installed in the factory. It has factory color calibration, perfect touchscreen sensitivity, and full system compatibility.
Copies (Copy, High Copy) fall into several quality classes. Budget options often have dimmer backlights, thickened glass and a less accurate touchscreen. Cheap copies for Redmi 9 often suffer from the proximity sensor and fingerprint scanner if it is built into the screen (although in this model the scanner is at the back, but the plumes can be poor).
The third option is Refurbished, which is the original displays that had broken glass but the matrix was intact, and the factory replaced the glass with the original matrix, which is the middle ground for price and quality, if the master did the job perfectly.
- 🔍 Original: Perfect color reproduction, the work of all sensors, high price.
- 📉 Copy: Understated brightness, possible "dead zones" touch screen, low price.
- 🔄 Refact: Original matrix, new glass, mid-price segment.

Why NFC Affects Part Selection
Xiaomi Redmi 9 with NFC has its own design features. NFC antenna module is often located at the top of the body or integrated into the display plumes. When poor-quality build or use cheap copies of displays, contact with the antenna can be disrupted or shielded.
If you choose a cheap analog, you risk losing the ability to contactless payment or fast pairing with devices. In some cases, after replacing the screen with low-quality NFC, it simply ceases to be determined in the system, since the wizard could damage the plume or not install the shielding pad in place.
Experts recommend that if you have NFC, you do not save on the class of spare parts. Checking the work of contactless payment should be a mandatory stage of acceptance of work after repair, this is the case when overpaying for the original or quality refact is an investment in the functionality of the device.
💡
After changing the screen, be sure to check the NFC by bringing the phone to the payment terminal or other device. If the feature does not work, require rechecking the connection of the plumes.
Self-Substitution or Service Center: Risk Analysis
Many users are looking at the price of components on marketplaces, but replacing glass with Redmi 9 at home without a separator is almost impossible — you just break the matrix, trying to peel off the fragments. You can only replace the entire module assembled, but there are nuances.
Careful disassembly requires special heating (thermofile or hair dryer), suction cups and mediators. The main problem is to carefully unstick the back cover and remove the frame without damaging the plumes. In Redmi 9, the display plume is quite thin and easily breaks when handled ineptly.
When you go to the service, you pay for the experience and the tools. The wizard knows how to apply the glue correctly, how not to overpress the matrix when you build it, and how to check the leakiness. A self-assembly error can cause dust to appear under the screen or the display to detach after a week.
- 🛠 Homes are difficult to find a professional separator and UV lamp for polymerization of glue.
- 💸 Guarantee: The service gives a guarantee for work, when you repair yourself, you risk everything.
- ⏱ Time: The professional will make a replacement for the 40-60 minutes, the newcomer can tinker half a day.

Comparative table of the cost of spare parts and works
To make it easier for you to understand prices, we have compiled a table with approximate prices, and note that prices may vary depending on the region and the specific service center.
| Part Type / Service | Approximate cost (ruble) | Quality. | Guarantee |
|---|---|---|---|
| Display module (Original) | 3500 - 5000 | High. | 6-12 months. |
| Display module (AAA Copy) | 1500 - 2500 | Average. | 1-3 months. |
| Replacement of glass (patching) | 2000 - 3000 | Depends on the master. | 1-6 months. |
| Work of the master (without spare parts) | 1000 - 2000 | - | Work. |
As you can see from the table, glass resticking can only be economically viable if the matrix is perfectly intact, but many services don't do it on budget models, because the risk of damage to the matrix is high and the profit is low, and it's often more profitable and reliable to buy a new module assembled.
💡
The most profitable option for the ratio of price / quality for Redmi 9 is the installation of a high-quality display module (Original Refurbished) in a specialized service.
