Broken security glass on a smartphone is one of the most common problems faced by owners of Xiaomi, Redmi and POCO devices. The screens of modern gadgets have become thinner and more sensitive to mechanical influences, so even a small fall on the asphalt can lead to cracks or βweb spidersβ. However, as practice shows, damage to the outer layer does not always mean the failure of an expensive display module entirely.
Many users mistakenly believe that broken glass requires a complete replacement of the screen, which significantly increases the cost of repair. In fact, if the image on the phone is not distorted, there are no black spots, and the touch screen (touch layer) responds to touch correctly, then only the top layer can be replaced. This allows you to save a lot by preserving the factory matrix, which costs the most. In this article, we will discuss in detail pricing, repair technologies and nuances that affect the final check amount.
Factors affecting the final cost of repairs
The price of glass replacement on Xiaomi phone is not made of air, but consists of several critical components. First of all, the cost depends on the model of your device and the technology used by the manufacturer in the assembly. Flagship models such as Xiaomi 13 or 14 Pro often have curved edges (curved) of the screen, making the procedure of replacing glass technically difficult and time consuming.
The second important factor is the equipment and consumables used. Quality repair requires a laminator to remove air bubbles and a separator to carefully separate broken glass from the matrix. In addition, the price varies depending on the type of adhesive: OCA (solid transparent adhesive) or LOCA (liquid adhesive). For budget models, LOCA liquid adhesive is often used, since it is easier to apply, but requires perfect sealing of the frames.
And the skill of a master is not to be discounted. Glass replacement is a piece of jewelry where one wrong move can kill the display. An experienced technician with professional equipment will take more for the job but guarantee the result. Cheap offers in garage workshops often result in the glass peeling off or dust particles under it in a week.
β οΈ Warning: If there are purple or black spots on the screen after the fall, or the image begins to flicker, only the glass can not be replaced.
Price difference: replacement of glass or module entirely
To help you better understand the pricing of service centers, let's break down the difference between the two main types of repairs: glass replacement is the process where a wizard carefully separates a broken exterior glass from a work matrix and glues a new one, which is only possible if the display itself functions perfectly, and the cost of this procedure is usually between 30% and 50% of the price of a new module.
Replacing the display module is a more radical and expensive method, which involves installing a new screen assembled (glass + matrix + frame) when the matrix is damaged or when gluing technology does not allow the layers to be separated without risk of destruction. For low-end Redmi models (for example, the entry-level Note series), it is often more cost-effective to buy a new module right away, since the cost of resticking can be comparable to the cost of a spare part.
The table below compares the average prices for repairs of the popular Xiaomi and POCO series of smartphones. Please note that the prices are indicative and may vary depending on the region and the exchange rate.
| Model/Series | Screen type | Price of glass replacement (sticking) | Module replacement price |
|---|---|---|---|
| Xiaomi Redmi Note 8/9/10 | Direct IPS/LCD | 1200 - 1800 rubles. | 2500 - 3500 ruble. |
| Xiaomi Mi 9T / Redmi K20 | Straight AMOLED | 2000 - 2800 rubles. | 4500 - 6000 rubles. |
| Xiaomi 11/12/13 (Pro/Ultra) | Curved AMOLED | 3500 - 5000 ruble. | 8000 - 12000 rubles. |
| POCO F3 / F4 / F5 | Straight AMOLED | 2200 - 3000 rubles. | 5000 - 7000 rubles. |
Recovery Technology: LOCA vs OCA
When choosing a glass replacement service, you may be asked what type of adhesive you have. Understanding the difference between LOCA and OCA will help you make an informed decision. LOCA (Liquid Optical Clear Adhesive) technology uses liquid adhesive. The wizard applies it to the matrix, covers it with new glass, then puts it in a UV lamp for polymerization. The good thing is that the adhes fills all the microsities, but requires high skill to avoid pouring the speaker or buttons with glue.
OCA (Optically Clear Adhesive) uses a pre-made transparent adhesive film, a more modern and reliable method that is more commonly used in factories, the film does not leak, does not dry over time and provides perfect transparency, but for Xiaomi with curved screens, it is more difficult to find quality OCA film, so they use proven LOCA more often.

When changing glass AMOLED-In the case of screens, be sure to require a quality frame or sealant. Cheap glue can cause glass to detach from the edges after a month of use.
Importantly, for models with Always-On Display, the quality of the adhesive is critical. Cheap formulations can turn yellow over time or let light out of the matrix, creating a rainbow effect on the edges of the display, so the savings on materials in this case are false.
Can I replace the glass by myself?
In theory, Xiaomi can also replace glass at home by buying a special set of tools and a new glass on marketplaces. However, in practice, replacing glass on its own without a separator and a laminator is almost impossible. The process requires heating the screen to 80-90 degrees, carefully cutting old glass with a string or blade, cleaning the matrix from glue and the perfect sticker of the new layer.
The main danger of self-repair is the high risk of damaging the polarization film or the matrix itself. If you accidentally push too hard when cleaning the glue, the screen may stop working or become covered with colored stripes. In addition, without a vacuum pump and a laminator, air bubbles will remain under the new glass, which will spoil the image.
Risks of home replacement
If you do decide to experiment, you'll need a hair dryer (building or powerful household), suction cups, a thin string (nichrome), a UV lamp, LOCA glue and a degreasing agent, but remember that the cost of a new glass with delivery and tool kit is often 70-80% of the cost of a professional replacement in the service.
Professional Replacement in the Service
Professional glass replacement in an authorized or specialized service center takes 1 to 3 hours, depending on the model. The process begins with a diagnosis: the wizard checks the touchscreen, the presence of broken pixels and the integrity of the plumes. Only when you make sure that the matrix is intact, the separation procedure begins.
First, the phone is disassembled, the battery is turned off, and the display module is removed from the housing. Then the separator (a device with heating and vacuum) carefully cuts the broken glass. After removing the old layer, the master carefully cleans the surface of the matrix of glue residues, using special solvents and microfiber, this is the most important step, requiring sterile cleanliness.
βοΈ Checklist of check after repair
In the final phase, a new layer of glue is applied (LOCA or OCA), a new glass is installed, and the structure is sent to the laminator under pressure to remove air. After polymerization in the UV camera, the phone is assembled back and tested. A quality glass replacement is visually indistinguishable from a factory assembly.
Warranty and service life after repair
One of the main questions that concern owners of Redmi and POCO is: how long will the screen live after repainting? When using quality materials and observing the technology, the replaced glass lasts as long as the factory glass. Many services give a guarantee of 3 to 12 months for the work performed. However, the warranty usually does not apply to mechanical damage (new falls, impacts).
It should be noted that after changing the glass, the phone loses its factory moisture protection (if it was), since the leakproofness of the case when opening is broken, so after repairs, you should be careful with water and dust, and it is also recommended not to wet the device in the first 24 hours so that the glue finally gained strength.
β οΈ Warning: Keep the check and the certificate of the work performed. In case of defects (detachment of glue, loss of sensitivity), this will be the only evidence for obtaining warranty service.
In conclusion, replacing the glass on a Xiaomi phone is a smart way to save money if the matrix is intact. Prices vary widely, but on average, it costs 2-3 times less to buy a new module. The main thing is to choose a proven service with good equipment and not try to save on materials by choosing the cheapest glue options.

Replacing glass saves up to 60% of the cost of repair, but is possible only with intact (whole) matrix and the absence of spots on the display.
