Owners of the legendary Redmi Note 4 (codenamed nikel or miden) often face the need to replace a broken display, as this smartphone, despite its age, remains popular due to its reliability. The question of how much to replace the screen becomes critical when the device stops responding to touches or cracks interfere with the review. The market for parts today is oversaturated with offers, but prices can vary several times depending on the quality of the matrix and the service chosen.
The cost of repairs is not only the price of the spare part itself, but also the complexity of the work, because this model uses OGS technology, where the glass and matrix are soldered into a single module. It is extremely difficult and risky to change them separately at home, so most users and craftsmen prefer to buy a complete module at once. Let's analyze in detail what the final amount depends on and how not to overpay for a poor-quality part.
The average price of services and parts is influenced by the exchange rate, as most components are imported, as well as by the type of display. The original IPS matrix manufactured by LG or BOE can cost 2-2.5 times more than a budget copy of the TFT type. Understanding this difference will help you make an informed decision: save now or invest in long-term operation of the device.
Factors affecting the final cost of repairs
The first thing that determines the price is the quality of the matrix itself. In the case of the Xiaomi Redmi Note 4, there are three main categories of parts: the original (Original), the quality copy (High Copy) and the cheap counterpart (TFT/LCD). The original screens have perfect color reproduction, wide viewing angles and an oleophobic coating that repels fat and the finger slides easily across the surface. Cheap counterparts often have distorted colors, low brightness and quickly fail.
The second factor is the format of the purchase. You can buy the display module separately and pay only for the cost, but then the installation work will have to be done independently or paid for by the master separately. In authorized service centers (ASCs) and large repair shops, the price is usually indicated on a turnkey basis, that is, including the work of the specialist, diagnostics and warranty. This is more convenient, but usually more expensive by 30-40%.
The third important aspect is the state of the bezels. Many of the Redmi Note 4's modules are sold pasted in a plastic frame, making it much easier to replace. If you buy a bare screen, the wizard will need to carefully move all the small parts (speaker, plumes, sensors) from the old bezels to the new one, which increases the time and cost of service, and the price may depend on the region and availability of the spare part in the warehouse.
Price comparison: original, copy and restored module
Display price spread for Xiaomi Redmi Note 4 It's big enough, and it's important to understand what you're paying for, and the original is a piece that's taken off a factory conveyor belt or manufactured using licensed technology, and it delivers the manufacturer's stated brightness to the point where it's going to be. 450 And the thread and the sensor work correctly, even when you use protective glasses, and the cost of such a module assembled with a frame can reach the level of the sensor. 2500-3000 RUB and higher, depending on the seller's margin.
High quality copies (often labeled as AAA+ Or Premium) visually almost identical to the original, but they may be inferior in durability to backlighting or color accuracy. They are the middle ground for budget repairs. Cheap. TFT-screens are around 800-1200 They consume more energy, have worse viewing angles and are often equipped with a glass sensor instead of a high-quality digitizer, making them more fragile.
There is also a Refurbished category where new glass is re-adhesived to the broken original array, a risky option because the quality of the adhesive and the procedure itself can be low. Below is an approximate table of the cost of components and work at the moment.
| Type of spare part | Part price (ruble) | Cost of work (ruble) | Total (roughly) |
|---|---|---|---|
| Original (IPS) | 2000 - 2800 | 800 - 1200 | 2800 - 4000 |
| Copy (AAA+) | 1200 - 1600 | 800 - 1000 | 2000 - 2600 |
| Budget (TFT) | 700 - 900 | 600 - 800 | 1300 - 1700 |
| Rebuilt | 1000 - 1300 | 800 - 1000 | 1800 - 2300 |
When choosing a cheap screen, you should consider that it may require replacement after 3-6 months of active operation. In addition, budget models often cannot install high-quality 3D protective glass due to the design of the sensor, which in the future will lead to repairs.
Why are the originals disappearing from the market?
Cost of self-replacement vs. service
When you decide to repair, you have to choose between doing it yourself or trusting the professionals. Self-replacement seems attractive because of the savings on the craftsman's job, which is about 30% of the total amount. However, for the Redmi Note 4, this process has its own nuances. The screen is glued to the case, and it requires heating and the use of special tools such as suction cups and mediators to remove it.
If you don't have experience, you're at risk of damaging plumes, breaking a new screen during installation, or breaking the seal of the case. At the service center, you pay not only for the time of the master, but also for the warranty. If the speaker falls off in a week or the sensor stops working, you're obliged to fix the malfunction for free. When you repair yourself, any mistakes fall on your shoulders financially.
⚠️ Note: When you replace your screen on Redmi Note 4, be sure to turn off the battery before connecting the new display plume. Turning on the phone with the screen plume connected when the battery is disconnected or vice versa can lead to short circuit and combustion of the power controller on the motherboard.
In addition, the service often conducts additional diagnostics of other nodes, for example, check the status of the battery or charging connector, which can save from future breakdowns. Self-repair is justified only if you are confident in your abilities and have the necessary tool.
☑️ What you need for a self-replacement
Where to buy parts: markets, online or services
Buying components is a lottery, if you don't know the places you've checked. Large online stores of mobile parts usually value their reputation and provide an honest description of the product, specifying the type of matrix. Here you can find both originals and copies, often with photos of the real product. Prices are average in the market, but there is a guarantee of return if the part turns out to be defective.
On popular marketplaces and Chinese online stores, prices may be lower, but the risks are higher. Often sellers write “Original” in the title, and in fact send a copy. Read reviews carefully, especially those where customers post photos of the screen on. Pay attention to the country of the sender: goods from warehouses in Russia will come faster, but may cost more.
Repair service centers typically buy parts in bulk from trusted suppliers. Buying a screen immediately installed in such a place gives you a single check and responsibility for the result. If you buy a part yourself and carry it to the master, many services can refuse a warranty for work or charge an additional fee for “risk”.
💡
When buying a screen online, be sure to ask the seller to check the integrity of the matrix before shipping. Many stores go along and can send a photo or video of the working display, which will save you from receiving a broken product.
Technical nuances of replacing the display on the Redmi Note 4
The process of replacing the screen with Xiaomi Redmi Note 4 is technically more complicated than on modern smartphones with a modular build. Here the back cover is glass and glued around the perimeter, which requires careful warming up and removal. Once the lid is removed, you can access the battery, which is also attached to the glue, and the plumes.
The challenge is that the display module itself is also glued to the front plastic bezel, and to replace it, you either need to buy the module already in the frame (which is recommended), or gently unstick the old broken screen, clean the frame of the glue residue and glue the new one. The use of B-7000 glue or a similar polymer composition here is critical to the reliability of the design.
Also, you should consider that after changing the screen, you may need to calibrate the sensor, and there is a special command in the phone's engineering menu, so if the sensor is not working correctly (missing touch or "phantomite"), this can be fixed software, but only if the digitizer itself is working.
Code for logging into the engineering menu (to check the sensor):
##6484##
(Select Touchpad or Sensor to check in on the menu)It is important to properly install the moisture pad (if it was bundled with the new module) or apply a new layer of glue around the perimeter so that dust does not get into the phone. Ignoring this step will cause dirt to quickly accumulate under the screen.
Frequent problems after screen replacement and their solution
Even after a successful replacement, there can be trouble, and one of the most common is a failed proximity sensor, and the screen may not go out during a conversation, leading to occasional cheekstrokes, often because of the wrong protective film on the sensor, or because of the factory failure of the screen itself, where the cutouts don't match.
Another problem is dead zones or stripes on the display, which indicates poor plume contact or matrix failure, so you need to take off the screen and reconnect the connector, making sure it snaps to the characteristic click, and if the stripes remain, the piece is defective and must be replaced under warranty.
⚠️ Note: If the phone has stopped seeing after the screen has been replaced SIM-If you're not tidy, you can easily move the clamping bars or damage the thin antenna plumes that go from the bottom board to the motherboard.
Users also sometimes complain of dim lighting or yellow tint, a sure sign that a cheap lighting system has been installed. TFT-copy IPS. Unfortunately, it is impossible to correct color reproduction or brightness in this case, only a repeated replacement with a high-quality matrix will help.
💡
The quality of soldering and assembly of a new module is often more important than the brand of the seller. Visual inspection of the plumes and the absence of distortions during installation is the key to long-term screen service.
Is it worth repairing Redmi Note 4 in 2026-2026?
On the one hand, the Redmi Note 4 still has a good margin of performance for basic tasks: calls, messengers, navigation and video. The Snapdragon 625 processor (in the global version) is famous for its energy efficiency. If the case is intact and the battery holds charge, replacing the screen will extend the life of the device for another year or two.
On the other hand, the cost of a quality original screen can be up to 70-80% of the market price of a used phone in working order. If you plan to install an expensive original matrix, it is more economical to consider buying another used smartphone in good condition.
Ultimately, the decision depends on your attachment to the device and your willingness to accept possible compromises as a picture, and for many, this phone remains a workhorse that is a pity to throw away because of broken glass.
