Why is the screen of the Xiaomi smartphone left a trace of the previous picture?
You open a new photo or video, and you see the contours of an old image appear on the screen -- as if someone had overlaid a translucent film -- this is called the afterglow effect or the "burn-in" effect in severe cases. AMOLED- and OLED-Xiaomi smartphone screens (Redmi Note series) 10/11/12, POCO X3/X4, Mi 11/12 where the pixels over time "get tired" and lose brightness unevenly.
80 percent of the time, the problem is solved software--without going to a service center, but if the trail lasts longer than 24 hours or is visible on a monochromatic background (like a white screen), it can signal irreversible pixel burnout, especially on smartphones older than 3 years, and then we'll look at how to distinguish a temporary defect from a critical one, and what to do in each case.
โ ๏ธ Important: Don't confuse afterglow with broken pixels (colored dots that don't change when you change the picture) or matrix artifacts (bands, flickering.
1. Rapid diagnosis: temporary trace or burnout?
Before you start "treatment", determine the extent of the problem.
- Change the background: open a bright monochromatic image (for example, pure white or red) to a full screen. If the trail disappeared after 5-10 minutes, this is a temporary afterglow.
- Check the video: run a dynamic video (like a movie trailer), and if the ghost remains static, it's burnout.
- Use test pictures: in Settings โ Screen โ In addition, some Xiaomi models have a built-in test for broken pixels.
๐ Signs of temporary afterglow:
- ๐ฑ The trail disappears after a reboot or after 10 to 30 minutes.
- ๐จ Only visible in dark or contrasting backgrounds.
- ๐ Appears after prolonged display of static elements (for example, navigation panels).
โ ๏ธ Warning: If you see the trail on any background and it doesn't disappear for days, it's irreversible burnout, and if you do, you can only replace the matrix (costs 3,000 to 15,000) โฝ model-wise).
2. Software methods of eliminating the trace (without disassembly)
If your diagnosis shows a temporary afterglow, start with these methods, which require no special skills and take between 2 and 20 minutes.
Calibration of the screen through the engineering menu
Many Xiaomi smartphones have hidden settings for resetting color.
- Open the Phone app.
- Enter the combination: ##6484## (for screen test) or #36446337## (engineering menu).
- Select Screen Test or Display, then Color Calibration.
- Click Reset or Restore Defaults.
โ ๏ธ Warning: Do not change other options in the engineering menu โ this may lead to loss of warranty or unstable screen performance.
2.2. โTreatmentโ with colour screensavers
The method is based on the uniform development of all pixels.
- ๐ฑ Install Screen Burn-In Fixer (Android) or AMOLED Burn-In Test.
- ๐จ Start a cycle of color screensavers (red) โ green โ blue-colored โ white for 10-15 minutes.
- ๐ Repeat the procedure 2-3 times with breaks.
๐ก Useful tip: If you can't install the app, use YouTube videos with color transitions. Turn it on full screen and leave it for 20-30 minutes.
โ๏ธ Preparation for color calibration
Resetting the screen settings
Sometimes the problem is that you're setting the color incorrectly, and you can bring it back to the factory values.
- Go to Settings. โ Screen.
- Choose Color Mode (or Color Style).
- Set the standard or default value.
- Turn off options like Automatic Contrast or Adaptive Display.
3. Hardware methods: when software does not help
If the traces remain even after the reset, the cause may be due to physical wear and tear on the matrix or problems with the screen controller.
3.1. Full reset of the phone (Hard Reset)
This method deletes all data, but sometimes solves problems with the graphics driver.
- Open Settings โ About the phone โ Reset settings.
- Select Delete all data.
- Confirm the action (a password may be required).
โ ๏ธ Note: On Xiaomi models with MIUI 13/14 After the reset, you may need to re-assign your Mi Account. Make sure you remember your login and password!
Checking the plume and screen contacts
If the trail is after a fall or a hit, the problem may be the disconnected plume, and it's risky to test it yourself, but you can try:
- ๐ง Carefully press the top and bottom of the screen (without undue effort!).
- ๐ Reboot your phone โ sometimes it temporarily restores contact.
- ๐ฆ If the trace disappears when pressed, contact the service for soldering the plume (cost: 1,500-4000). โฝ).
What if the screen starts to flicker after a fall?
Replacement of screen: when justified
If all methods did not help, and the trail interferes with the use, you will have to replace the matrix.
| Smartphone model | Cost of the matrix (โฝ) | Cost of work (โฝ) | Totally (โฝ) |
|---|---|---|---|
| Redmi Note 10 Pro | 4 500โ6 000 | 1 500โ2 500 | 6 000โ8 500 |
| POCO X3 Pro | 5 000โ7 000 | 1 500โ2 500 | 6 500โ9 500 |
| Xiaomi 11T | 8 000โ12 000 | 2 000โ3 000 | 10 000โ15 000 |
| Redmi 9A (LCD) | 2 500โ3 500 | 1 000โ1 500 | 3 500โ5 000 |
๐ฐ Tip: Before replacing, check to see if it's cheaper to buy a used phone of the same model. For example, the Redmi Note 10 Pro on Avito can be found for 10,000-15,000. โฝ.

Replacing the screen in an unofficial service can lead to loss of leakage (dust/moisture under the glass) or incorrect operation of the fingerprint sensor.
4. How to prevent the appearance of traces in the future
You don't have to treat it, you have to warn it.
- โฑ๏ธ Reduce the time of displaying static elements: turn off the always active display (Settings) โ Screen. โ Screensaver) and reduce sleep timeout to 15-30 seconds.
- ๐ Alternate wallpaper: Don't use the same bright images for months. Change them every 1-2 weeks.
- ๐ Lower the brightness: keep it at 50-70%. Maximum brightness accelerates wear. OLED-pixel.
- ๐ฎ Limit game time: In dynamic games, pixels wear out evenly, but static interface elements (for example, a map to a game). PUBG) may leave traces.
๐ Term of service AMOLED-The risk of burning out increases by 2-3 times with moderate use - 3-5 years.
5. frequent user errors (what NOT to do)
Many people try to remove the mark, and they make the problem worse.
- ๐ฅ Heating the screen with a hairdryer or battery โ this can damage the matrix or glue holding the glass.
- ๐งฒ Magnets use โ they affect compass and sensors, but not pixels.
- ๐ง Attempts to โwashโ the trail with alcohol are a physical defect of the matrix, not dirt on the glass.
- ๐ง Disassembling the phone without experience โ the risk of damage to plumes or battery.
โ ๏ธ Attention: Forums sometimes advise you to "swipe the screen" through Fastboot. It's a myth - firmware does not affect the physical state of pixels. McMoom, what it can do is reset the color settings, but this is already described in section 2.1.
6. Comparison of AMOLED and LCD: Which screen is less prone to footprints?
If you are choosing a new Xiaomi smartphone and are worried about the traces, pay attention to the type of screen:
| Parameter | AMOLED/OLED | LCD (IPS) |
|---|---|---|
| The risk of afterglow | High (due to organic pixels) | Absent. |
| Contrast | High (deep black) | Medium (lighting is always on) |
| Energy consumption | Low (dark pixels do not consume energy) | High (lighting always works) |
| Term of service | 3-5 years (degradation of brightness) | 5-7 years (stable work) |
| Xiaomi models with such a screen | Redmi Note 11 Pro+, Xiaomi 12, POCO F4 | Redmi 9A, POCO M3, Redmi 8A |
๐ก Conclusion: If you are interested in the durability of the screen without the risk of traces - choose models with a high-quality screen. LCD. But be prepared for higher power consumption and less saturated colors.

On smartphones with AMOLED, turn on a dark theme โ it reduces the load on pixels and saves battery power.
