Xiaomi's smartphone screen is not just a display, it's a key element of interaction with the device. When it starts to "glut" — flickering, showing artifacts, spontaneously pressing buttons or refusing to turn on — it's out of the ordinary. The reasons can be very different, from a simple software failure to serious hardware failures. In this article, we will analyze all possible malfunction scenarios, learn how to distinguish "treatable" cases from those that require the intervention of specialists, and give step-by-step instructions for self-repairing.
It is important to understand that Xiaomi produces dozens of models – from budget Redmi to flagship Mi and other models. POCO, And the way we approach diagnostics can be different, AMOLED-screens (installed in Xiaomi 13 Pro or POCO F5 Pro) are more likely to suffer from pixel burnout, and IPS-Matrices (in Redmi Note 12) from broken subpixels after impacts, we will take these nuances into account and offer solutions that are relevant to most devices of the brand.
Before you panic and bring your phone to the service, go through our checklist. In 70% of cases, the problem is solved without disassembling the case — just resetting, updating the firmware or calibrating the sensor. And if the screen is still “dead”, we will tell you how to save on repairs and avoid cheating in the workshops.
1. Diagnosis of the problem: how to accurately determine the malfunction
The first step is to identify symptoms correctly, and it depends on what you do next, and here are some of the most common “glitch” of Xiaomi screens and their possible causes.
- 🔄 The screen spontaneously turns on / off - the failure of the proximity sensor, damage to the plume or firmware.
- 🖥️ Artifacts (stripes, stains, distorted colors) – damage to the matrix, graphics chip or plume contacts.
- 👆 Sensor does not respond to touch (or reacts incorrectly) – screen contamination, calibration failure, damage to digitizer.
- 🌑 Black screen, but the phone works (sounds, vibration is) - plume dump, failure of the backlight or graphics driver.
- 🔥 Screen flickering or flashing - backlight malfunction, application conflict, failure in MIUI.
- 💥 Cracks or broken pixels after falling – mechanical damage to the matrix (requires replacement).
If your case is not on the list, try recording a video of the problem, which will help to describe the symptoms more accurately to the master or on the forum.
- Go to dial mode and type ##6484## (to check the display).
- Or use ##4636## → “Equipment Testing” → “Display”.
- For models on Qualcomm, ##225## (calibration check) is suitable.
Critical point: if the screen reacts to touch, but the image is distorted, try connecting the phone to the PC via a computer. USB-Debugging (included in Settings) → The phone. → Version. MIUI → 7 times to tap the version, this will help save data if you need to reset.
2. Software glitches: reboot, reset and update
In 50 percent of cases, the screen glitches are caused by software errors, not hardware, and let's start with the simplest and safest methods.
Forced reset
If the screen is getting stuck or unresponsive, but the phone is showing signs of life (vibrates, lights are on), try a hard reboot:
- 📱 For most models: Press the power button + Increase volume by 10-15 seconds.
- 🔋 If it doesn’t work: connect the charger and try again (sometimes helps with a discharged battery).
After the reboot, check if the problem persists. If so, move on to the next step.
2.2 Resetting settings via Recovery
If the reboot didn’t help and the screen is partially working (e.g., you can see the image but with artifacts), try resetting to factory settings.This will delete all the data, but often solves problems with the display drivers.
Backup (if the screen reacts a little)
Charge your phone at least 50%
Remove the SIM and memory card (if any)
Prepare the unlock code MI-account (if it was linked to)-->
- Turn off the phone (clip Power + Volume Up to Vibration).
- Press Power + Volume Up until the Mi logo appears.
- In the Recovery menu, select Wipe Data → Wipe All Data (manage volume buttons, confirmation – power button).
- After reset, select Reboot.
Important: if after resetting the phone requires the entry of a password from MI-account, and you do not remember it, it will be difficult to restore access - Xiaomi blocks devices after resetting without detachment of the account.
Update or reflash MIUI
Screen failures can be caused by firmware bugs, especially after updates. Check the relevance of the MIUI version:
- 📲 Go to Settings. → The phone. → Updating the system.
- 🔄 If you have an update, install it (preferably via Wi-Fi).
- 🛠️ If the update doesn’t help, try manually flashing through Fastboot or Recovery (instructions for a specific model look at the following: 4PDA Xiaomi Community).
💡
Before you run your firmware, check the phone model in Settings → About Phone → Model. Installing firmware from another model can “brick” the device!
3. Hardware malfunctions: what can be done independently
If the software methods didn't work, the problem is probably hardware, and let's look at the most common cases and how to fix them without disassembling the phone.
Display plume dumping or damage
Symptoms: the screen periodically goes out, stripes appear, or the image flickers when you press the body, often after falls or severe vibration.
Decision:
- 🔧 Carefully press the phone body in the area next to the volume buttons (there is a train.
- 🛠️ If you're an experienced user, you can take your phone apart and reconnect the plume (you need a set of screwdrivers and patience). POCO Often suitable universal plumes with AliExpress (cost) ~300–500 ₽).

Lack of illumination
Symptoms: the screen is dim, the backlight is flashing or completely absent (the image is visible only at an angle).
Reasons:
- 💡 The exit LED-lighting (often on the AMOLED-screen).
- 🔌 Problems with power backlight (burnt out resistor or transistor on the board).
Decision:
- 🔦 Light a flashlight on the screen at an angle - if the image is barely noticeable, the problem is in the backlight.
- 🔧 The service will replace the backlight or the entire screen module (cost from 2 000). ₽). Self-repair is complicated - a soldering station is required.
Damage to the matrix or digitizer
Symptoms: cracks, broken pixels, broken zones of the sensor.
Decision:
- 🔍 If there are no cracks but the sensor is not working, try recalibrating it through the engineering menu (#6484##).
- 💸 For mechanical damage, only a screen replacement.For Xiaomi, prices vary: Screen type Model Cost of replacement (₽) Redmi Note 10/11IPS LCD3 500–5 000 POCO X3/X4IPS LCD4 000–6 000 Xiaomi 12/13AMOLED8 000–12 000 Redmi 9A/9CIPS LCD2 500–4 000
💡
Replacing the screen in an unofficial service can lead to loss of leakage (dust, moisture under the screen) or incorrect operation of the sensor. Always check the warranty for work!
4.Sensor problems: calibration and cleaning
If the screen does not respond to touches or presses buttons on its own, not only a hardware failure, but also a software conflict can be to blame.
Sensor calibration
For calibration:
- Enter the dialer ##6484##.
- Select the Touch Screen Test.
- Follow the instructions on the screen (usually touch the crosses several times).
If calibration didn’t help, try turning off gestures in the settings:
- Go to Settings → Display → Full-screen mode.
- Select navigation buttons instead of gestures.
Screen cleaning and film checking
Sometimes the sensor gets bugged because of:
- 🧴 Fat marks on the screen (wipe with microfiber with isopropyl alcohol).
- 📱 Sticked film or glass (poor quality can block the signal).
- 💧 Moisture under the screen (if the phone falls into the water).
💡
If the sensor is only operating in a certain area (e.g., at the edges), it can be a sign of the digitizer detachment, in which case only a replacement screen will help.
5. When to contact the service: signs of serious breakdowns
Not all problems can be solved by yourself, but here are the signals that it is time to bring the phone to the workshop:
- ⚡ The screen does not turn on at all (no lighting, sounds, vibrations).
- 🔥 There is a smell of burning or the phone overheats.
- 💥 After the fall, the screen “went waves” (damaged matrix).
- 🔌 Phone is not charging or discharges quickly (maybe the charge is damaged).
The cost of repair in the service depends on the model and type of breakdown:
| Type of repair | Average price (₽) | Date(days) |
|---|---|---|
| Replacement of the plume | 1 000–2 500 | 1 |
| Replacement of illumination | 2 000–4 000 | 1–2 |
| Replacement of the matrix (IPS) | 3 500–6 000 | 1–3 |
| Replacement of the matrix (AMOLED) | 8 000–15 000 | 2–5 |
| Board repair (screen power) | 5 000–10 000 | 3–7 |
How to choose a service:
- 🔍 Check reviews on Yandex.Maps or 2GIS.
- 📋 Ask if you have a job guarantee (at least 3 months).
- 💰 Check if the original parts are used (for the purpose of the AMOLED It's critical).
💡
Xiaomi's official service centers often overprice parts. Unofficial workshops can make it cheaper, but the risk of running into poor repairs is higher. Always ask for a check and a guarantee!
6.Prevention: How to Avoid Screen Problems in the Future
To make the Xiaomi screen last longer:
- 📱 Use high-quality protective glass (such as Spigen or Nillkin).
- 🧤 Don’t press too hard on the screen (especially on the screen) AMOLED — pixel burnout).
- 🔋 Avoid full battery discharge – this can cause a malfunction of the display.
- 🌡️ Do not leave your phone in the sun (overheating damages the matrix).
- 🔄 Update regularly MIUI — In new versions, bugs with screen drivers are corrected.
If you drop your phone frequently, consider Gorilla Glass-protected models (like the Xiaomi 13T or POCO F5). For budget Redmis, you can buy a bumper with shock-absorbing corners.
