A broken screen on Xiaomi is one of the most common breakdowns faced by smartphone owners. (Redmi Note) 12, POCO X5, Mi 11 etc.) the cost of replacement at the service centre may be 30-50% However, with the patience and the right tools, you can replace the screen on Xiaomi yourself, which will save you a lot of money. 70% In this article, we will discuss the entire process: from the diagnosis of damage to the final testing of the new display.
It's important to understand that the complexity of repairs varies depending on the design of the smartphone. AMOLED-screens (Xiaomi 13 Pro, Mix Fold 3) require accuracy when working with flexible plumes, and budget devices (Redmi) A2, POCO M6) They often have adhesive display fixation that is easier to separate.We will look at the universal steps relevant to most Xiaomi devices, and also point out the key differences for flagships and budget lines.
Before you start repairing, assess the scale of the problem: if the screen does not respond to touch, but the image is there, the touchscreen is to blame; if the display is completely black, but the phone vibrates when turned on, there may be a malfunction of the plume or motherboard.
1.Diagnostics of damage: when a screen replacement is really needed
Cracks on the screen don't always mean that a complete module replacement is required, but here are three main scenarios in which repairs are warranted:
- 🔧 Cracked glass with a working touchscreen: if the sensor responds to touch, and the image is not distorted, you can limit yourself to replacing only the protective glass (cheaper in the case of a glass). 2-3 However, for models with OLED-displays (e.g., Xiaomi) 12T) This is often impossible – the glass is integrated into the matrix.
- 📵 Black screen with the device running: if the phone is on (sounds, vibrations), but the display is not glowing, the problem may be in the plume, backlight or the matrix itself.
- 🔄 "Fluid touchscreen: When the screen reacts to late touch or pushes buttons spontaneously, the touchpad controller is to blame. In 80% of cases, only replacing the entire module helps.
If the screen is completely broken and the smartphone does not show signs of life (it does not vibrate, it does not charge), the problem may lie in a short circuit on the motherboard, in which case replacing the display will not bring the device back to life - you will need comprehensive repairs.
⚠️ Note: Xiaomi models with Always-on Display (e.g. Mi 11 Ultra, 13 Pro) may require calibration of the light sensor even after the screen is replaced.
For accurate diagnosis, connect your smartphone to your computer through USB-C Check if it is detected in Windows or through the adb device command Android. SDK). If the device is recognized, the problem is exactly in the screen.
2. Selection of a new screen: original vs. analogues
The quality of the module being replaced not only affects the appearance, but also the functionality of the smartphone, and there are three types of screens for Xiaomi on the market:
| Screen type | Pluses | Cons | Price (rupe) |
|---|---|---|---|
| Original (OEM) | 100% compatibility, all functions are maintained (AOD, HDR, 120 Hz) | It is hard to find for old models. | 8 000 – 25 000 |
| Premium copy | Quality close to original, supports basic functions | There may be problems with color reproduction or touch screen | 4 000 – 12 000 |
| Budget copy | Low price, quick delivery | Low resolution, no available AOD, Possible dead pixels | 1 500 – 5 000 |
For models with AMOLED-displays (Xiaomi) 12 Pro, Mix 4) It is recommended to buy only original modules or copies from proven manufacturers (for example, the manufacturer is not required to buy them, JDI, Samsung Display.Cheap counterparts often have issues with automatic brightness and support for high refresh rates (90/120 Hz).
When choosing a screen, pay attention to:
- 🔍 Smartphone model: even in one line (for example, Redmi Note 11) can be different versions of the screen for global and Chinese firmware.
- 📦 Set: the set must have adhesive tapes for fixation, plumes (if not integrated) and protective film.
- 🔧 Availability of touchscreen: some sellers offer only a matrix without a touch layer - this option is not suitable.
Checked areas for purchase: AliExpress (shops) HQ Cellphone Parts, Digi-Flavor, eBay, local service centers (sometimes sell used originals after replacement).
3. Necessary tools: what will be needed for repairs
To replace the screen on Xiaomi will require a specialized set of tools.
- 🔧 Plastic mediators (2-3 pc): to separate the screen from the body without scratching.
- 🔥 Dryer or thermo-air station: for softening the glue (optimum temperature - 60-80)°C).
- ⚙️ Screwdrivers: cross-hairdriver (PH00) and five-beam (Pentalobe) for Xiaomi screws.
- 🧲 Magnetic mat or tray: so as not to lose small details (screws, clips).
- 📏 Suction cups (2 pcs): to raise the screen after heating.
- 🔌 Multimeter: to check the lighting circuits and plumes (optional, but useful).
- 🧴 Isopropyl alcohol (90%+): glue-cleaner.
- 🎨 Double-sided tape or glue B-7000: fixate.
The cost of a full set of tools - from 1,500 to 5 000 rubles. If you plan to repair smartphones regularly, it makes sense to buy a professional kit (for example, iFixit Pro Tech Toolkit).
⚠️ Warning: Do not use metal mediators - they can damage the plumes or body. Also avoid overheating the screen with a hairdryer: temperature above 90°C can damage OLED-battery.
For models with moisture protection (IP53) (Xiaomi 13, Redmi Note 12 Pro+) You'll need to restore the leakage after you change the screen. UV-glue and ultraviolet lamp (cost of set — ~1,000 rubles.).

4. Step-by-step instructions: how to disassemble Xiaomi and replace the screen
The screen replacement process can be divided into 5 key steps. Follow the instructions carefully - errors at any step can lead to additional breakdowns.
Step 1: Disconnect and heat the body
Turn off your smartphone and remove the tray for SIM-Then warm up the edges of the screen evenly with a hair dryer for 2-3 minutes, holding it at a distance of 5-7 cm. The purpose is to soften the glue, but not overheat the display.°C).
Step 2: Separation of the screen from the body
Attach the suction cups to the bottom of the screen (where the charging connector is) and gently pull up. Insert a plastic mediator into the resulting slit and slowly guide it around the perimeter, separating the screen. Be careful about the flexible plume (usually on the right or bottom) - it is easy to damage!
If the screen doesn't respond, reheat the problem area. AMOLED (For example, Mi 11) the plume is often glued to the back cover - it must be carefully disconnected with a mediator.
Step 3: Disconnect the plumes and batteries
Once the screen is separated, you'll see the battery and the motherboard, and the first thing you do is turn off the battery connector (usually marked in red or black) with a plastic blade, which will prevent short circuits.
Then disconnect the screen plumes, which can be captured:
- Latch (lift it up with a screwdriver).
- Screw them and carefully pull out the plume.
- Glue (please use the mediator).
⚠️ Note: On Xiaomi models with a backlit screen on a separate plume (for example, POCO F4 GT) If you turn off the LEDs incorrectly, if the screen is lit after assembly, but the image is missing, check the lighting circuit with a multimeter.
Step 4: Install a new screen
Move all the additional parts (speaker, front camera, sensors) from the old screen to the new one. Then plug the plumes in reverse and lock them. Before final assembly, temporarily plug the battery and turn on the phone to check the new display.
If it works,
1. Apply bilateral scotch or glue B-7000 perimeter.
2. Carefully press the screen, starting at the top.
3. Twirl the screws (do not pull!).
4. Warm up the edges with a hair dryer (temperature 50)°C) for better fixation.
Step 5: Final check
After assembly, check:
- Does the touchscreen react to touch (use the test in Settings) → The phone. → All parameters. → Equipment test).
- Does the automatic brightness work (cover the light sensor with your hand).
Are there artifacts on the display (bands, broken pixels).
If you find problems, take the phone apart again and check:
- The density of the plumes.
- Integrity of contacts on the motherboard.
- Display settings in Settings → Screen (sometimes update frequency is lost).
What if the screen doesn’t work after replacement?
5. Frequent mistakes and how to avoid them
Even the skilled craftsmen sometimes make mistakes when changing the screen. TOP-5 Problems and ways to prevent them:
- 🔋 Battery damage: when the screen is separated, the mediator can puncture the battery. Solution: use plastic tools and don't push too hard.
- 📶 Breaking antenna contacts: on some models (Xiaomi) 12T) antennae Wi-Fi/4G Solution: Before disassembling, take a picture of the contacts.
- 🎨 Bad fixation of the new screen: if the glue is applied unevenly, over time, there will be gaps. UV-fixation.
- 🔌 Mixed plumes: some Xiaomi display and touchscreen plumes are separate. Solution: check the connection scheme for your model.
- 🔍 Broken pixels: Cheap screens often have defects. Solution: Check the reviews of the seller before you buy.
Another common problem is that the proximity sensor is broken after the screen is replaced, and this is because the plume is not connected correctly or damaged, so to check the sensor, call your phone and put your palm over the top, the screen should go out, and if that doesn't happen, take the device apart and check the contacts.
On models with infrared port (Xiaomi) 10T, POCO X3) When you change the screen, the remote control can stop working, and that's because the IR sensor is often attached to the back cover, and when you don't build it, it shifts, and the solution is to take the phone apart and align the position of the sensor.
💡
If the phone starts to drain faster after changing the screen, check if you have damaged the battery contacts or charging plume, sometimes the cause is a malfunction of a new display (for example, the constantly active Always-on Display).
6. Replacement of the screen on popular Xiaomi models: features
The design of the screen and the way it is mounted can vary greatly depending on the model. Let’s consider the nuances for the most popular Xiaomi smartphones:
| Model | Screen type | Features of replacement | Difficulty (1-5) |
|---|---|---|---|
| Redmi Note 12 Pro+ | AMOLED, 120Hz | It's a thin plume, it requires a little bit of precision when you disconnect, and the light sensor is integrated into the screen. | 4 |
| POCO X5 Pro | AMOLED, 90 Hz. | Easy access to the plumes, but the screen is glued very tightly - you need a powerful hair dryer. | 3 |
| Xiaomi 13 | AMOLED, 120 Hz, HDR10+ | Difficult disassembly due to protection IP53. Required. UV-sealant. | 5 |
| Redmi A2 | IPS LCD, 60 Hz | Simple replacement, the plumes are securely fixed, suitable for beginners. | 2 |
| Mix Fold 3 | Flexible AMOLED | Replacement is possible only in the service center - special equipment is required. | 5+ |
For Xiaomi with a high refresh rate (90/120/144 Hz) after the screen change may require calibration through the engineering menu:
- Enter the code ##4636##.
- Choose Equipment Testing → Display.
- Check support for all update modes.
On stylus-enabled models (Xiaomi Pad 6, Mix Fold), the Wacom digital pen may not work after the screen is replaced, because the touch layer for the stylus is integrated into the original matrix, the solution is to buy the original screen or refuse to use the pen.
7.Substitution cost: comparison of self-repair and service center
The price of a screen replacement in Xiaomi’s official service depends on the model and type of breakdown. For comparison, here are the average prices for 2026:
| Model | Cost in the service (ruble) | Screen price (ruble) | Savings in self-replacement |
|---|---|---|---|
| Redmi Note 12 | 6 000 – 9 000 | 2 500 – 4 000 | 60% |
| POCO X5 | 7 000 – 10 000 | 3 000 – 5 000 | 55% |
| Xiaomi 13 | 15 000 – 22 000 | 8 000 – 12 000 | 50% |
| Mix Fold 2 | 30 000 – 50 000 | 20 000 – 35 000 | 30% |
Self-replacement is beneficial not only from a financial point of view, but also in time: in the service center repairs can take from 3 days to a week, whereas at home you can cope in 1-3 hours (depending on experience).
However, consider the risks:
Loss of warranty (if the phone is warranty, the service center will refuse repair after self-intervention).
Damage to other components (for example, the motherboard when working with a screwdriver in a careless manner).
Incompatibility of the new screen (especially relevant for copies).
If you’ve never repaired a smartphone, we recommend you practice on your old device first or watch video instructions for your model on YouTube (Fixez, Repair Universe channels).
1.The cost of repair in the service exceeds 50% of the price of the phone.
2.You have experience with small electronics.
3.You are willing to spend time searching for a quality screen and tools.
Otherwise, it is better to turn to professionals.-->
8.Alternative solutions: when replacing the screen is not appropriate
In some cases, replacing the screen can be unnecessarily expensive or technically difficult.
- 🔄 Sale for parts: if the cost of repair exceeds 70% of the price of a new smartphone, it is more profitable to sell a faulty device (on Avito, Yule or specialized sites like FixPrice).
- 📱 Use of external display: for models with support USB-C → HDMI (For example, Xiaomi 13 can connect an external monitor and use the phone as a mini PC.
- 🔧 Partial repair: if only glass is broken and the matrix is intact, you can apply a protective film or use a phone with cracks (not recommended for the use of a stained glass). AMOLED, as the glass can be broken down).
- 🆕 Upgrade to a new model: If your Xiaomi is older than 3-4 years, it may make sense to consider buying a new smartphone (e.g. Redmi Note 13 Pro).+ or POCO F6).
For models with a bendable screen (Mix Fold, Mix Flip) self-replacement is almost impossible – you need special equipment to calibrate the flexible matrix, in this case, repair in the service will cost 30-50,000 rubles, which is often comparable to the cost of a new phone.
If you decide to sell a faulty Xiaomi, indicate in the ad:
- Exact model and year of release.
- The nature of the breakdown (for example, "the screen is broken, the touch screen does not work, the rest is working").
Battery status (capacity can be checked through AccuBattery)
This will increase the chances of a quick sale.
