A broken smartphone screen is always a frustrating situation that gets you off track and makes you look for urgent solutions. For owners of the popular Xiaomi Redmi 8, the cost of restoring the display is especially acute given the budget class of the device. Many users face the dilemma of trying to save and replace only cracked glass or changing the entire display module, which will cost much more.
The price of a service can vary widely, and it is influenced by many factors, ranging from the region of residence to the qualification of the master. In this article, we will discuss in detail what the total amount is, what are the risks when choosing cheap parts and why it is sometimes more profitable to overpay for quality than in a month again to carry the phone in service.
You have to understand that glass replacement and module replacement are fundamentally different processes. One is to carefully remove the broken layer from the matrix and roll in a new one, which requires professional equipment. The other is to simply change the entire unit assembly, and it is the choice of recovery method that directly determines how much money you will have to spend on repairing your Redmi 8.
โ ๏ธ Attention: If the crack is from the edge of the screen and affects the side face, the risk of damage to the matrix or plume during dismantling increases significantly.
Factors affecting the final cost of repairs
Prices in service centers and private workshops are not random, but are based on several key components. The first and most important factor is the type of spare part used. In the Xiaomi component market, there is a gradation of original parts, high-quality copies and frankly cheap low-quality counterparts, the price difference between them can be as high as 50-70%, which significantly affects the repair budget.
The second important aspect is the complexity of the work and the equipment required: the procedure of replacing only glass (lamination) requires a separator, a friser (freeze) and a laminator. Not every service has such a fleet of equipment, so often the masters offer a replacement module assembly, which is technically simpler, but financially more expensive for the owner of the smartphone.
Price is also affected by the urgency and location of the service center, in large cities and shopping centers, renting space is higher, which inevitably reflects in the price lists. In addition, if urgent repairs are required "with a customer", the cost can be higher than when you put the device into operation for several days.
| Type of spare part | Image quality | Touchscreen sensitivity | Term of service |
|---|---|---|---|
| Original (OEM) | Great, bright colors. | Perfect. | 3-5 years |
| Copy (AAA+) | Good, maybe yellow. | Good. | 1-2 years |
| Budget copy | Dim, low brightness | Delays, omissions. | 3-6 months |
โ ๏ธ Attention: Cheap copies of displays often lack oleophobic coating, making the finger slip worse and the screen get dirty faster.
Average prices in the service market in 2026
Analyzing the current situation in the market of repair services, we can identify an approximate price corridor relevant to the model Redmi 8. the Cost of replacing the module assembly (screen + touchscreen + frame) on average ranges from 2500 to 4500 rubles depending on the quality of the spare part. If we are talking about gluing only glass, the price usually varies in the range from 1500 to 2500 rubles, since the spare part itself (glass) costs a penny, but the work requires high qualification.
It is worth noting that the cost of replacing a module assembly is often lower than the cost of resticking glass if you do it yourself. However, in the service, glass resticking can cost less than a full replacement module, since the master does not buy an expensive matrix, but only wastes his time and consumables (adhesives, films). For a budget Redmi 8, replacing the module is often a more rational choice in terms of reliability, despite the slightly higher price of the spare part.
Remember to consider the additional costs. For example, if the back cover or frame is damaged in a fall, replacing them will also require a financial investment. Sometimes the craftsmen offer a comprehensive service "body restoration", which may be more profitable than changing parts separately. Always check the total amount before work begins to avoid unpleasant surprises.

When calling the service, always ask if the price includes the work of the master and glue. Often the price is announced only for the spare part, and on the spot they add 500-1000 rubles for the work.
Comparison: replacement of glass or module in the assembly
The choice between replacing only the glass and replacing the entire module is not just a matter of price, but also a matter of feasibility. Replacing the module assembled for the Xiaomi Redmi 8 is technically simple: the wizard unplugs the old unit, rearranges the internal components (motherboard, battery, cameras) into a new case with a screen and assembles the phone. This method ensures that you get a device with a new matrix, a new frame and a fresh touchscreen.
Glass replacement (lamination) is a more subtle process, which involves removing broken glass from the working matrix, cleaning the glue residues and rolling new glass in a vacuum chamber. The main risk here is to damage the matrix during the glass removal process. If the matrix cracks or there are stripes, repairs will become economically inefficient, as the cost of the new matrix approaches the price of a new phone.
- ๐จ Module replacement: Faster, more reliable, higher final price, but less risk of damage to internal components.
- ๐ Glass replacement: Cheaper (in some cases), retains the original matrix, but there is a risk of rainbow spots or air bubbles.
- โฑ๏ธ Time: Module changes for 30-60 For a few minutes, the glass may take 2 hourly 2 Days (depending on the workload of the laboratory).
For the Redmi 8, which is a low-end model, it often makes no sense to save 500 rubles on glass pasting, risking image artifacts. The new matrix on the module copy may even be better than the old one, which burned out for several years of use.

For budget smartphones like the Redmi 8, replacing the module in the assembly is often more profitable and safer than the risky glass resticking on the old matrix.
Can I replace the glass by myself?
Many users, wanting to save money, consider the option of self-repair. Theoretically, replacing the module assembled with the Redmi 8 is possible at home, if you have a set of tools and straight hands. However, replacing only glass at home is almost impossible without expensive equipment (separator and laminator), so we will talk about replacing the module.
The process requires care. The back of Xiaomi is glued to the glue, and it needs to be warmed up with a hairdryer. There are many plumes inside that are easy to tear by careless movement. There is also a risk of damaging the battery, which can lead to its fire. If you don't have experience disassembling electronics, you better not take the risk.
โ๏ธ Checklist for self-replacement of the module
โ ๏ธ Note: When you replace the module yourself, you lose the warranty on the device (if it was still valid) and the tightness of the case.
If you do, make sure to use quality consumables. A cheap B-7000 glue can not hold the lid, and a poor-quality screwdriver can lick the screws. It is also important to connect the display plume correctly: a skew when inserting a connector can burn the power controller on the board, which will bring the phone down completely.
How to Choose a Reliable Service Center
The choice of a repair site is critical. There are many offers on the market, but not all of them are honest. The first sign of good service is transparency. You should immediately state the full cost, explain the difference between the original and the copy, and show the part itself before installation. Avoid places where you say "bring, see," without even giving an approximate price.
Pay attention to the presence of a warranty card. In the work on replacing the display with a normal warranty period, 14-30 days are considered normal, and for the spare part itself (especially the original), the warranty can reach 6-12 months. If the master says that there is no warranty on the glass, this is reason to doubt his qualifications or honesty.
- ๐ Location: Larger chains often offer more guarantees, but charge more for rent. Private craftsmen in the mall can make cheaper, but the risk of running into incompetence is higher.
- ๐ Documents: Always demand a work-by-work certificate or a check.This is your main claim document if the screen falls off in a week's time.
- ๐ Reviews: Explore profile forums and maps. Look not just for "good / bad", but for specific cases based on the Redmi 8 model.
