How much it costs to change the glass on the Xiaomi phone: prices and nuances

A broken smartphone screen is always a frustrating situation that gets you out of your way and makes you look for a solution. If you have Xiaomi with a cracked security glass in your hand, but the display itself continues to work and show the image without distortion, you are more fortunate than many. In this case, we are talking about a partial repair, which is technically called glass only, which is a procedure much cheaper than a full replacement of the module, but it requires specific equipment and high skill of the master.

Many users are asking, why can't you just buy a new glass and stick it on your own like a protective film? The answer lies in the technology of modern smartphones. The glass is glued to the display matrix with optically transparent LOCA or OCA glue, which provides perfect light transmission and sensitivity touchscreen. It requires a vacuum separator and laminator to apply and remove the old layer, making home repairs almost impossible without the risk of permanently dipping the matrix.

In this article, we will discuss in detail what the final cost of the service is, why prices can vary three times in different services, and whether it is worth taking up the restoration of broken glass at all or it is easier to replace the entire module. Understanding these processes will help you not to overpay and avoid unscrupulous masters who can deceive you by replacing the expensive original with a cheap counterpart.

⚠️ Warning: If you have black spots, stripes, or touchscreens that are no longer responsive to touch in certain areas, replacing one glass won't help.

What the final cost of repair depends on

The price of the service is not taken from the ceiling and is formed from several objective factors. The first and most important parameter is the smartphone model. flagship devices in the Xiaomi Mi or Xiaomi 13/14 series have curved edges of the screen (2.5D or even 3D bend), which greatly complicates the process of dismantling and sticking new glass. Working with waterfalls requires jewelry accuracy, so the price tag for such models is always higher than on the budget Redmi with flat screens.

The second factor is the quality of the materials and the glue used. Quality restoration requires glue that doesn't turn yellow over time and retains optical properties. Cheap analogues can go bubbles or cloudy spots in a month, and cost is also included in the depreciation of expensive equipment: separators, laminators and UV lamps cost thousands of dollars, and services have to pay back these investments.

And the reputation of the workshop is not to be forgotten. Services that provide a 3 to 12-month warranty initially put risks in the price. If you are offered to change glass suspiciously cheaply, it is likely that the master works on his knee without observing temperature regimes, which can lead to detachment of the glue at the first overheating of the processor.

💡

Always ask what glue is used for the glue. Professionals use it. UV-glue (LOCA/OCA), which harden under ultraviolet light and provide better adhesion than conventional transparent adhesives.

Price comparison: replacement of glass or a whole module

The main question that confronts the owner of a broken Redmi or POCO is: which is more profitable? replacing only glass (repairing) usually costs from 30% to 50% of the cost of a new display module. However, there is a caveat: for budget models (for example, Redmi Note 8, 9, 10), the cost of a new original module can be so low that the savings on repatching become impractical.

If a new module costs 2,500 rubles and a glass replacement cost 1,500 rubles, it doesn't make much difference. But when you replace the module, you get a new phone in terms of the screen: a fresh battery (often assembled with a frame), a perfect frame and no trace of glue. When you reglaze the glass, you leave the old matrix, which already has a lifeline.

The original display on the Xiaomi 13 Pro can cost 15-20 thousand rubles and more. In this case, replacing glass for 4-5 thousand rubles looks very attractive, especially if the matrix is intact. However, the risk of damaging the matrix when removing old broken glass remains always, and a good master will definitely warn you about this before starting work.

💡

For low-cost models Redmi is more profitable and reliable to immediately change the display module in the assembly, as the difference in price is minimal, and the quality of the result is guaranteed.

Technological process and risks

The process of replacing glass is not just "pick and stick"; it's a multi-step engineering procedure. First, the master must separate the broken glass from the matrix. This is done by using a special machine, a separator, which heats the adhesive layer and, with a thin thread or blade, carefully separates the glass. At this stage, the risk of damage to the matrix is maximum: any improper movement can damage the plumes or the structure itself. OLED/LCD panel.

After separation, the residues of the old glue must be thoroughly cleaned, done manually or by special machines, using special solvents that should not damage the oleophobic coating (if it survives) and the polarizing filter. Then a new layer of LOCA liquid glue is applied, which is evenly distributed throughout the surface, and the air bubbles are removed in the vacuum chamber.

The final step is to polymerize the glue under powerful UV lamps for a period of time, and only after the glue has crystallized completely, the phone is reassembled, and any failure of the technology at any stage (underheating, dust, poor vacuuming) will cause the glass to peel off or become rainbow stains.

⚠️ Note: After glass replacement, the touchscreen sensitivity may be slightly lower than that of the factory module due to the different thickness of the adhesive layer.This is normal for refurbished displays, but should not interfere with comfortable use.

The impact of Xiaomi on the complexity of repairs

Xiaomi and the sub-brands Redmi and POCO are extremely diverse, and the design of the devices has a huge impact on the price. Entry-level devices often have a plastic frame and flat glass that is held on double-sided tape. These are the easiest to repair, but as mentioned above, it is rarely economically justified.

More difficult is the Xiaomi Mi series (starting with the Mi 10) and the new flagships of the Xiaomi 13/14 series. It uses In-Display Fingerprint technology and curved edges. When replacing glass on such models, it is critical not to damage the layer responsible for reading the fingerprint, otherwise the function will cease to work. In addition, curved edges require the use of glass with a precise bending (2.5D), which is more expensive than a flat counterpart.

A separate category is Black Shark gaming smartphones (developed with Xiaomi support), which have complex cooling systems and often unique connectors, and are harder to find glass and require disassembly of the case, which increases repair time and, accordingly, the cost of service.

Where to replace: service or private

Choosing an artist is a balance between price and quality assurance. Xiaomi’s official service centers (ASCs) often don’t do glass reglazing at all. Their standard procedure is to replace the display unit assembled with the original one. It’s reliable but expensive. For them, the question of how much to change the glass is often irrelevant, since they only offer a full replacement.

Specialized mobile repair service centers are the best option for glass reglazing, they have the necessary equipment (separators, laminators) and experience, and here you can be offered a choice: put glass with an oleophobic coating (expensive) or conventional (cheaper), it is important to pay attention to the reviews and the availability of a guarantee for the work of gluing.

Private craftsmen at home or in small shopping centers can offer the lowest price, but the risk of running into poor-quality glue or an inexperienced specialist is maximum here. Individuals often do not have vacuum chambers to remove bubbles, which in the future will lead to “snowflakes” or detachments at the edges of the screen.

💡

Ask the wizard to show you your old glass after the removal, and it should show that the matrix was not really damaged, and the cracks were only on the outer layer, which will confirm the honesty of the artist.

How long does recovery take?

Unlike replacing a module that takes 30-40 minutes, glass gluing is a long process. Even if the wizard is fast, the process takes time. The average lead time is 2 to 4 hours, and it takes time to clean, apply the glue and, most importantly, polymerize it.

Some services offer a service "on you", but it is often a marketing ploy. Really high-quality gluing in 30 minutes can not be done - the glue simply does not have time to grasp. If you promise to make a flagship Xiaomi in an hour, you should be wary: perhaps the wizard will miss the phase of vacuuming or reduce the drying time, which will affect durability.

In rare cases, if you need glass of a rare model or a specific color (for transparent versions of phones), the period can be extended to 1-2 days until the part is delivered from the warehouse.

⚠️ Warning: After glass is replaced, it is not recommended to expose the phone to extreme loads (bath, frost, shocks) in the first 24 hours.The glue should finally gain strength, and any sudden temperature changes can disrupt the adhesion.
