How much to replace the screen on Xiaomi Mi 9: a full analysis of prices

Owners of flagship smartphones such as the Xiaomi Mi 9 often face an unpleasant situation when the front panel is broken after a fall or mechanical impact. At this point, the user is faced with the question of whether to repair, given the age of the device and current market realities. AMOLED-The display can vary widely, and understanding pricing will help avoid unnecessary spending.

The price is made up of several factors: the quality of the component (original or copy), the cost of work of the masters in the service center and additional costs of delivery or urgency. It is important to understand that the Xiaomi Mi 9 has a screen with a built-in fingerprint scanner, which greatly complicates the replacement procedure compared to budget models. Poor build or cheap part can lead to a broken fingerprint sensor or problems with the touch screen.

In this article, we will discuss in detail what the total check amount in the service is formed from, whether to buy a display module for self-installation and what pitfalls are hidden behind attractively low prices in the market of spare parts. It is critical to consider that when replacing the screen with the Mi 9, it is often necessary to repaint the frame, which increases the cost of work.

Factors affecting the final cost of repairs

The first thing that determines the price is the type of display module. In the spare parts market for Xiaomi Mi 9 (model M1903F11G), you can find three main categories of components, each with its own price niche. The most expensive option is the original module with the OLED marking, which fully meets the factory specifications for brightness, color reproduction and response speed.

Cheaper analogues, often called "copies" or "replicas," can vary significantly in image quality, often using In-Cell-type matrices that cannot reproduce the deep black and saturated hues characteristic of the original. AMOLED-In addition, budget modules often lack oleophobic coating, and the glass may be less durable.

The second important factor is the workload. Replacing the screen with the Xiaomi Mi 9 is a complex process, requiring heating the case, carefully removing the back cover (which is glass and easily beats), and turning off many plumes. If the repair requires replacing the frame or body, the price will rise. The cost is also affected by the region and the service center policy: in large cities, the rent and salary margins for masters will be higher.

Price comparison: original vs. quality copy

The price difference between the original display and its counterpart can reach a double size, which makes many users think about the feasibility of overpaying. However, when choosing a spare part for the Xiaomi Mi 9, the savings can come out sideways, since this smartphone is positioned as a multimedia device with an emphasis on image quality.

The original module ensures that the Always On Display function works correctly, that colors are displayed correctly in DCI-P3 mode, and that 60Hz video frequency (or 90Hz in some modes if supported by firmware) is stable. Cheap copies often have a low-brightness “shimmer” effect (PWM), which can negatively affect the user’s vision.

The following table shows the approximate distribution of prices in the market of spare parts and repair services at the moment, prices are shown in rubles and can vary depending on the exchange rate and the specific region.

It is worth noting that buying a module with an already pasted frame is often justified, as it speeds up the assembly process and ensures the tightness of the case. Self-adhesive pasting of the old frame on a new screen requires special glue B-7000 or T-7000 and skills with adhesive compounds.

💡

When buying a display, always check the configuration: the set should have disassembly tools and adhesive base if the module is without a frame.

Hidden costs when replacing the display

When planning a budget for repairs, many people forget about the associated costs that can occur during the work. For example, when removing a broken screen, the back cover of the Xiaomi Mi 9 is often damaged, since it is glued around the perimeter. If the service is not warned about the risks, replacing the cover will be an unpleasant surprise.

Another expense is the battery, because you have to take the entire smartphone apart and remove the battery to replace the screen, and there's a high risk of damaging it, and if the battery is a few years old, it makes sense to replace it preventively while the phone is disassembled, which would add another 1,000 to 1,500 rubles to the check for a new battery and work.

⚠️ Warning: If the under-display fingerprint scanner is no longer working after the screen is replaced, the problem may not be the display, but the wrong plume or lack of calibration. In cheap copies, the scanner may not work at all.

Also worth considering is the shipping cost if you order a part online rather than buying from a local store. The original module can take 2 to 4 weeks to wait, while copies are often available. Time is also a resource that has value.

Self-Replacement: Is the Risk Worth It?

For users with technical mindset and experience with electronics, self-repair can be a way to save up to 50% of the cost of service. However, the Xiaomi Mi 9 is not one of the devices that are easy to disassemble by a beginner. The design of the smartphone involves a dense layout and use of a large amount of glue.

You'll need special tools to do the surgery: a thermophen or heating pad, suction cups, mediators, a set of Phillips and Torx screwdrivers, and tweezers, and the absence of at least one of these tools can cause the body to break or damage the internal components.

The replacement process begins with the device switching off and retrieval. SIM-Then you need to heat the perimeter of the back cover to a temperature of about 80-90°C to soften the glue. With the lid carefully removed, you need to turn off the battery plume to turn off the board, and then start dismantling the motherboard and the old display.

How to check the quality of the installed screen

Once the repair is done, it is important to conduct a thorough diagnosis to ensure the quality of the work performed and the spare part itself.You should not limit yourself to just turning on the phone; you need to check the operation of all sensors and display colors. For the Xiaomi Mi 9, checking the fingerprint scanner is especially important.

In the smartphone's engineering menu, you can run display tests. In the Phone app, dial ##6484##. In the CIT menu that opens, select tests related to display (Display), color (Color) and touch screen (Touchpanel), which will reveal dead pixels or areas that do not respond to touch.

• 🎨 Color rendering check: Turn on white image at maximum brightness – the background should be uniformly white, without yellow or pink spots.
• 🖐️ Multi-touch test: swipe multiple fingers across the screen at the same time to make sure all points are tracked correctly.
• 🔋 Heat check: when working on a bright white screen, the phone should not heat up in the display area stronger than usual.
• 📶 Sensor operation: check the proximity sensor during the call and autobrightness.

If you notice that the maximum brightness is lower than it was before the breakdown, or the colors look faded, you probably have a low-quality copy installed, in which case you should raise the issue of warranty in front of the craftsman or store.

💡

The warranty for the work of the master and the display module itself in authorized services is usually from 3 to 6 months, which is an important criterion for choosing a repair site.

Where is better to repair: service or private?

The choice of repair site directly affects the final cost and risks. Official service centers Xiaomi will offer only original parts and professional equipment, but the price will be maximum, and the timing can be stretched due to waiting for delivery. Private workshops often work faster and cheaper, but it is important not to run into unscrupulous performers.

When contacting a private service, be sure to specify which module will be installed. The phrase "original" in the ad can mean "original copy" or "restored module." Demand a guarantee in writing and a check for payment. A good wizard will always give time to check the phone right in front of you.

⚠️ Avoid services that offer to “re-stick” your broken glass onto a new matrix during the course of the day. 1-2 Good quality factory gluing (OCA Lamination takes hours or days and requires industrial equipment.

If you’re choosing between buying a used phone for parts and repairing your own, do a calculation.Sometimes the cost of a refurbished Xiaomi Mi 9 with a full screen on the aftermarket can be comparable to the cost of repairing your current device, but with a bonus of a serviceable battery and case.
