Broken smartphone display is always an unpleasant situation that turns a modern gadget into a pile of useless plastic and glass. the Redmi Note 4 model, released by Xiaomi, is still popular due to its reliability, but even the most durable devices are not immune to accidental falls. Owners often wonder about the feasibility of repair, because the cost of a new budget smartphone can be comparable to the cost of restoring the old one.
But you shouldn't rush to buy a new device, because replacing the screen on this model is a well-established and affordable procedure. The cost of repairing the display module itself, the quality of the spare part and the markup of the service center or the master, and understanding these components will help you avoid overpayments and poor-quality repairs.
In this article, we will discuss the price policy of the spare parts market in detail, explain the difference between original parts and quality copies, you will learn why the replacement price can vary by twice in different workshops, and what to look for when choosing a performer.
Factors affecting the final cost of repairs
The first thing to understand is that the price is not taken from the ceiling. There is a clear gradation in the repair market, which depends on the type of matrix used. The display module for the Redmi Note 4 (the model is often labeled as MDE6S or MDT6S) can be made using different technologies, and this directly affects the repair budget.
The most expensive option is the original part with the marking OEM. Such screens fully meet factory specifications for brightness, color reproduction and sensor sensitivity. IPS-Matrixes of good quality, so the difference between the original and the cheap analogue will be noticeable to the naked eye.
The second factor is the complexity of the work. While replacing the glass and display with the Redmi Note 4 isn't technically a very complicated operation, it requires care. The wizard needs to unstick the old module, clean the frame of the glue residue and install a new one. Some services already include a bezel replacement, others have a separate paid option.
Price is also affected by the warranty period: cheap workshops "at home" can offer low prices, but do not give any guarantee or limit to 7 days. Official or large service centers include risk and liability in the price, providing a guarantee of up to 6 months or more.
Pricing policy: Original vs. Copy
The main expense is the display module itself. In the spare parts market for Xiaomi, there is a steady practice of dividing into quality categories. The price of the original screen on the Redmi Note 4 assembled with a frame can vary from 2,500 to 3,500 rubles and higher, depending on the exchange rate and logistics.
The cheapest ones, often called "Hard Glass" or simply "China," are from the Chinese. 1000 before 1500 They have thicker frames, they transmit colors less well and often have less responsive sensors "OLED-copy" (although there is a IPS) or "High Copy," standing in the neighborhood. 1800-2200 The ruble and visually almost indistinguishable from the original.
โ ๏ธ Warning: Buying a cheap copy may lead to a touchscreen dead zone or auto-brightness, and a $500 savings could result in a re-repair in a month.
It is important to consider that Xiaomi original parts often come in factory packaging with a hologram and protective film, while copies come in simple cardboard boxes or bags with antistatics. If you are offered an "original" without packaging at the price of a copy, this is a reason to doubt the honesty of the seller.
How to distinguish the original from the copy before installation?
Comparative table of the cost of spare parts and works
To make it easier for you to navigate the numbers, we've compiled a summary table, which is relevant for the current period and may vary slightly depending on the region and the service.
| Part Type / Services | Cost of the part (ruble) | Cost of work (ruble) | Total amount (ruble) |
|---|---|---|---|
| Original (OEM) with frame | 2500 - 3200 | 800 - 1200 | 3300 - 4400 |
| High quality copy (High Copy) | 1600 - 2000 | 800 - 1000 | 2400 - 3000 |
| Budget copy (Hard Glass) | 900 - 1300 | 600 - 800 | 1500 - 2100 |
| Replacement of Glass Only (Original) | 1000 - 1500 | 1500 - 2000 | 2500 - 3500 |
The table shows that replacing the glass (re-sticking) on the original matrix may be more profitable than replacing the module completely with a cheap copy, but this service is only available if the display (matrix) is intact and only the external glass is broken.
The cost of the work depends on the complexity of the dismantling. In the case of the Redmi Note 4, the procedure is standard, but requires heating the case to soften the adhesive. Some services charge an additional fee for urgency or travel of the wizard to the client.

The optimal choice for the ratio of price / quality is often a high-quality copy, as visually it is not inferior to the original, but costs 30-40% cheaper.
Technical nuances of replacing the display on the Redmi Note 4
The process of replacing the screen with the Xiaomi Redmi Note 4 has its own features that everyone who plans to repair should know about. The design of the smartphone involves using a large amount of glue to fix the module to the frame, which makes the process of disassembling the time-consuming.
The wizard needs to carefully disconnect the plumes without damaging them, since the touchscreen plume and the matrix plume can be combined or separated depending on the revision of the board. Incorrect connection can cause the power controller on the motherboard to fail.
- ๐ ๏ธ Disassembly: Requires heating of the perimeter of the body to 80-90 glue-softener.
- ๐งน Cleaning: You must completely remove the old glue from the plastic frame, otherwise the new module will get crooked or unstuck.
- ๐ง Fixing: The new module requires special glue B-7000 or T-7000 and fixation 1-2 half-hour.
- ๐ Battery: In some cases, temporary battery extraction is required to safely access the plumes.
Another important point is calibration: After installing the new screen, you may need to programmatically calibrate the sensor, and on Xiaomi devices, this is done through engineering menus or special utilities if the sensor is not working properly (for example, โruns awayโ to the side).
โ๏ธ Checking the master before repair
Should I change the screen by myself?
Many users, seeing the cost of spare parts on marketplaces, think about self-repair. Theoretically, replacing the screen with a Redmi Note 4 is possible at home, if you have experience with small electronics and the necessary tool.
But the risks are high, and the main danger is to damage the plume when installed or to overheat the body with a hairdryer, which will detach the plastic from the back cover or blow up the battery, and without vacuum suction cups and thin mediators, it is very easy to crush the new matrix in the process of gluing.
โ ๏ธ Warning: Self-replacement will deprive you of the warranty for the part itself if you install it incorrectly.
If you do, make sure to buy a quality glue and tool kit. Don't use superglue (cyanacrylate) - it creates pairs that settle on the camera lens and matrix, leaving a whitish coating that can not be removed.

Before starting a self-replacement, be sure to take a photo of each stage of disassembly and arrangement of the screws. This will help not to confuse anything during assembly.
Where is it better to repair: service or private?
The choice of repair site directly affects the total amount. Xiaomi official service centers (Mi Service) work only with original parts and have a fixed price list. This is the most reliable, but also the most expensive option, where you pay for the brand, warranty and compliance with all technological regulations.
Private workshops and mobile craftsmen offer more flexible prices, can offer a choice of 3-4 matrix options at different prices, and private specialists have the advantage of speed and bargaining, especially if you bring your own parts (although there is usually no guarantee or minimal guarantee for working with other people's parts).
When choosing an artist, pay attention to the reviews and availability of equipment. A good service will always show you the part before installing, let it check (plug the plume and turn on the phone) and only then begin to glue.
