A cracked or broken screen on Xiaomi is one of the most common breakdowns faced by smartphone owners. A service center can charge anywhere from 3,000 to 10,000 rubles, depending on the model, and repair time often stretches for several days, while replacing the screen with Xiaomi can be done on its own, saving up to 70% of the cost and gaining invaluable experience.
This article will suit the owners of most popular models of the brand: from the budget Redmi Note 10/12 and POCO X3/X5 to the flagships Mi 11 Ultra or Xiaomi 13 Pro. We will analyze not only the process of dismantling and installation, but also the nuances that are often missed in the general instructions: how to avoid damage to the plumes, how OLED differs from AMOLED when replacing, and why the touchscreen may not work after repair. If you have never disassembled a smartphone, do not worry: with our step-by-step instructions and video examples, even a beginner can cope in 1-2 hours.
Important: before you start, evaluate the scale of the problem. If the screen is completely black, but the phone is making sounds and vibrating, the problem may be in the plume or motherboard, not the display. In this case, self-repair without diagnosis can aggravate the breakdown. For accurate diagnosis, use the combination of Loudness up + Power - if the Fastboot menu appears on the black screen, the display is definitely defective.
Preparation: tools and spare parts
The first thing to do is buy an original or high-quality screen counterpart. Xiaomi will be suitable for displays from manufacturers BOE, Samsung (for AMOLED), Tianma or JDI. Avoid cheap “no-name” screens with AliExpress – they often have poor color reproduction, incorrect sensor performance or quickly fail.
Where to look for parts:
- 🛒 Xiaomi official service centers – sell original screens, but at an inflated price (suitable for models on warranty).
- 🔧 Parts stores (for example, FixPriceService, MobiPart, GSMMaster) - the best option for price / quality.
- 🌍 Overseas sites (eBay, Amazon) – suitable for rare models, but delivery can take up to a month.
List of necessary tools:
| Tool. | Appointment | Where to buy |
|---|---|---|
| Plastic shoulder blades (mediator) | Separation of the shell without scratches | Renovation kits in Ozon or Wildberries |
| Screwdriver T3, T4, T5 | Xiaomi screws are usually under Torx | Any tool store |
| Fryer-dryer | Softening of glue (temperature 60–80 °C) | Construction shops |
| Screen suction cup | Lifting the display after heating | Included in remakes |
| Isopropyl alcohol (90%+) | Cleaning glue residues | Pharmacies or radio shops |
⚠️ Warning: Do not use metal blades or knives to disassemble the body! Even a small scratch on an aluminum frame can become a source of corrosion, and damage to the plume will lead to a broken touchscreen.
For example, the Redmi Note 10 Pro has two types of displays: DM-C10Q-P (120 Hz) and DM-C10-P (60 Hz). If you install the wrong screen, you will get a sensor malfunction or no high refresh rate. You can check the model in the phone settings (Settings → Phone → MIUI version) or through the CPU-Z application.
2. Disassembly of the smartphone: a step-by-step process
Start by turning off your phone and retrieving it. SIM-cards and memory cards (if any:
- Heat the case. Turn the dryer on to the minimum power (or set the temperature 60-70 ° C at the thermo-air station) and evenly warm the edges of the screen for 2-3 minutes. This will soften the glue that holds the display. Don't overheat! Temperatures above 90 ° C can damage the battery or plumes.
- Lift the screen. Attach the suction cup to the bottom of the display (where the charging connector is) and gently pull up. If the screen doesn't respond, warm up the edges again. Once there's a gap, insert a plastic blade and slowly move it around the perimeter, separating the display from the body.
- Disconnect the plumes. When you take off the screen, you'll see 1-3 plumes (depending on the model) attached to the latches. Carefully apply the latches with a screwdriver and disconnect the plumes. AMOLED-screens (e.g. Xiaomi) 12T) The touchscreen plume and display are often combined into one – do not pull it around the corner so as not to break it!
Features of disassembly for popular models:
- 📱 Redmi Note 11/12: The battery plume is located under a metal cover - it must be unscrewed with a screwdriver. T3.
- 📱 POCO X4 Pro: The display is mounted on 12 screws - do not lose them when disassembling!
- 📱 Xiaomi 13 Lite: The front camera plume is integrated into the screen module – when replacing the display, the camera will also have to be transferred.

If the screen cracks but still reacts to touch, back up your data via Settings → About Phone → Backup or connect your phone to your PC in MTP mode before disassembling. After replacing the display, all data will be saved, but if the plume is damaged during repair, there is a risk of losing information.
3. Installation of a new screen: nuances and errors
Before installing the new display, clean the case of old glue with isopropyl alcohol and a napkin without pile. Do not use acetone or solvents - they can damage plastic parts!
Next:
- Apply new glue. Optimally use 3M double-sided tape (0.1-0.2 mm thick) or B-7000 liquid glue. If you use Scotch, cut the strips along the contour of the screen, leaving holes for the speaker and cameras.
- Connect the plumes. Start with the widest one (usually a display plume), then connect the touchscreen and additional plumes (such as the front camera or light sensor). Click all the connectors until the characteristic click.
- Place the screen carefully on the body, combining screw holes and connectors. Start at the top, then gradually press the screen against the body, avoiding distortion.
⚠️ Note: On models with an infrared port (for example, Xiaomi Mi). 10T) When you install the screen, it's easy to damage the IR sensor. Check it after it's built in the Mi Remote app.
Common errors in installation:
- 🔌 Fragile fit of plumes - leads to flickering of the screen or "dead zones" touch screen.
- 📏 Screen skewing – if the display is unevenly installed, over time the glue will peel off, and gaps will appear.
- 🔥 Overheating when drying glue – some masters use a dryer to accelerate the polymerization of the glue, but the temperature is above 50°C can deform plastic clips.
After setting the screen, don't turn the phone on immediately. Let the glue dry for 10-15 minutes (or 1-2 hours if you used liquid glue), then gently press the screen around the perimeter and check if there are any gaps.
💡
If the screen is working after the replacement, but the touchscreen does not respond to touch, check if the sensor plume is connected. On some models (for example, the Redmi 9A), it is hidden under metal protection and requires additional disassembly.
Testing and calibration
Turn on the phone and check:
- 🎨 Color rendering: Compare the shades to another device. Cheap screens often have a greenish or bluish tint.
- 👆 Touchscreen: Test multi-touch (simultaneous touches in different zones) with the Touch Screen Test app.
- 🔊 Speakers and microphone: Call your phone or record a voice note to make sure the holes aren't blocked.
- 📶 Sensors: check the proximity sensor (during the call, the screen should go out) and illumination (automatic brightness adjustment).
If the touchscreen is not working properly (for example, touches are recorded with a bias), calibration may be required.
- Go to Settings → System → Additional → Screen calibration (on some firmware, the path may differ).
- Follow the instructions on the screen by touching the crosses at the specified points.
- If you don’t have a calibration point, install the Touchscreen Calibration app from Google Play.
In the models with AMOLED-After replacing, you can experience a pixel burn, or residual images from old icons, not a defect in the new screen, but a feature of the technology. To eliminate the effect, use the Screen Burn-In Fixer app or play a 1-2 hour video with running colors on YouTube.
What to do if the screen flashes after replacement?
Frequent problems and their solutions
Even with a careful replacement, there can be problems.
| Problem. | Possible cause | Decision |
|---|---|---|
| The screen is off. | Display plume is not connected or the motherboard is damaged | Check the connection of the plumes, test the phone with a known working screen |
| Touchscreen's not working. | Sensor plume or incompatible screen is damaged | Reconnect the plume, update the firmware, check the screen model |
| There are "dead" pixels | Screen marriage or mechanical damage during installation | Return the screen to the seller under the guarantee or replace it with another one. |
| The proximity sensor is not working. | The sensor plume is not connected or blocked by the screen | Take the phone apart and check the position of the plume |
| The screen spontaneously presses | Poor calibration or sensor damage | Calibrate if it doesn’t help – replace the screen. |
If after the replacement the screen works, but artifacts (strips, flickering, distorted colors) appeared, the reason may be:
- 🔌 Bad plume contact - try reconnecting it or clearing contacts with alcohol.
- 🔋 Lack of power – check if the battery is swelling (it can press on the plumes).
- 📱 Incompatible firmware – some models require a phone to be flashed through Fastboot after changing the screen.
⚠️ Note: On models with a subscreen fingerprint scanner (such as the Xiaomi Mi 11), the scanner may stop working after changing the screen, because the sensor is glued to the inside of the display and is often damaged when dismantled. In this case, you will need to replace the entire screen module with a sensor.
6. Tips for extending the life of a new screen
To make the new screen last longer, follow these guidelines:
- 🛡️ Use a protective glass and cover – even a small impact on the corner can lead to a crack.
- 🔋 Avoid overheating – do not leave your phone in direct sunlight or on charging near heat sources.
- 💧 Avoid getting moisture, even if the phone has protection. IP53, The glue under the screen gets soaked over time.
- ⚡ Charge with the original cable – cheap cables can cause voltage surges that damage the display controller.
If you drop your phone a lot, consider a high impact screen. For example, for the POCO X3 Pro, they release displays with a protective layer of Gorilla Glass Victus, which are 2 times stronger than standard ones. They cost 20-30% more, but pay off when you first drop.
Also, pay attention to the brightness of the screen. AMOLED-In the case of displays at maximum brightness, the pixels wear out faster. To extend the life of the display, set automatic brightness adjustment or limit the maximum to 70-80% in the developer settings (Settings) → The phone. → Version. MIUI → 5 times to tap → For developers → Limitation of brightness).
💡
If the phone starts to run out faster after changing the screen, check if the high refresh rate (for example, 120 Hz) is still on, and on some models it is reset to factory settings after repair.
7.The cost of repair: comparison with the service center
Replacing the screen on your own is cheaper, but it takes time and care. Consider the comparison table for popular models (prices are up for 2026):
| Xiaomi model | Screen price (self) | Cost at the service center | Savings |
|---|---|---|---|
| Redmi Note 12 | 2 500 – 3 500 ₽ | 4 500 – 6 000 ₽ | 2,500 ₽ |
| POCO X5 Pro | 3 000 – 4 000 ₽ | 5 000 – 7 000 ₽ | up to 4,000 ₽ |
| Xiaomi 13 Lite | 5 000 – 6 500 ₽ | 8 000 – 10 000 ₽ | up to 5,000 ₽ |
| Xiaomi 12T Pro | 7 000 – 9 000 ₽ | 12 000 – 15 000 ₽ | up to 8,000 ₽ |
| Redmi 10A | 1 500 – 2 000 ₽ | 3 000 – 4 000 ₽ | 2,500 ₽ |
When calculating savings, consider that the service center often offers a warranty for repairs (usually 3-6 months), when replacing the screen, only the screen seller guarantees (if you bought from a trusted store), and the SC may offer additional services, such as replacing the battery or cleaning the charging connector, which will increase the total cost.
If you are not confident in your abilities, but want to save money, consider the option of "self-substitution with advice." Some service centers offer rental tools and help with a wizard video call (cost about 1 000 000). ₽). It is cheaper than a complete repair and reduces the risk of errors.
