Owners of modern smartphones Xiaomi, Redmi and POCO often face unpleasant visual defects that can appear after prolonged use of the device, this is a residual image, when the screen is barely visible traces of static interface elements, such as keyboard, navigation buttons or status bar icons, this phenomenon causes panic among users who fear that the matrix of their gadget irretrievably damaged and requires expensive replacement.
However, not always the appearance of βghostsβ on the display indicates a fatal breakdown. AMOLED-Most of the time, we're dealing with a temporary effect that can be corrected by software or by a simple change in usage habits, and understanding the physical nature of this process is the first step to successfully solving a problem without going to a service center.
In this article, we will discuss in detail how to distinguish between temporary effect and burnout, what built-in MIUI and HyperOS tools can help in the fight against artifacts, and when to think about replacing the display module. We will consider both safe ways to βcureβ the screen, and myths that can only make things worse with your device.
The nature of defects on AMOLED screens
To effectively combat the problem, you need to understand its origin. Modern Xiaomi smartphones are predominantly equipped with AMOLED or Super AMOLED arrays. In such displays, each pixel glows independently thanks to organic LEDs. Over time, the organic matter that emits light degrades and loses its brightness. If certain pixels were used more intensively than others (for example, displayed a white status bar), they burn out faster, creating a difference in color reproduction.
It is important to distinguish between two basic concepts: Burn-in (burnout) and Image Retention (residual image). Burnout is the irreversible physical wear of organic matter when a pixel ceases to emit light at the same intensity. Residual image is a temporary state where pixels "remember" a previous state due to charge in capacitors or short-term overheating, but are able to recover.

Use a dark interface theme β this not only saves battery power, but also reduces the load on blue and white subpixels, prolonging the life of the screen.
On Xiaomi devices with high refresh rates (90, 120 Hz and higher), the likelihood of artifacts being produced may be higher due to the more intense work of the power controller. OLED-It's the combination of high brightness and static content that creates the perfect conditions for defects to occur.
Diagnosis: Burnout or temporary effect
Before running any utility for "treatment", you need to conduct a thorough diagnosis. Often users mistake temporary sticking of flowers for permanent burnout. To check, turn on the all-white image at maximum brightness and carefully examine the screen when the automatic adjustment is turned off.
If you see clear keyboard contours or icons that do not change their intensity over time 15-20 When you're in a smartphone, it's probably a Burn-in. If the image turns pale, changes color, or disappears completely after you reboot or change the picture, you're dealing with Image Retention. 100%.
For accurate diagnosis, you can use special test images that are easily available on the Internet for the "screen burn test": uploaded (single) images of red, green and blue colors, uneven glow in one of the colors will indicate the degree of degradation of specific subpixels.
Built-in protection and recovery of MIUI and HyperOS
Xiaomi engineers are well aware of the problem of burnout OLED-panels, so in the shell MIUI And the new HyperOS has built-in protection algorithms, and one of the key tools is the image shift function, which, unobtrusively, shifts the image a few pixels in different directions so that the load is evenly distributed.
You can check for these features and status in the settings menu. The path is usually: Settings β Screen β Burnout Protection (or similar item depending on the firmware version). Make sure the switch is activated. Also pay attention to the screen timeout: set it to a minimum value (30 seconds) so that the static picture does not burn too much time.
βοΈ Setting up screen protection
Newer versions of firmware have introduced an advanced color calibration mode that sometimes helps to smooth out the difference between burnt-out and normal zones. Although this does not treat physical wear, the visual effect becomes less noticeable, and the system can automatically reduce the maximum brightness of the static display, which is a normal protective reaction.
Software Methods of Treatment of Residual Image
If the diagnosis shows that this is a temporary residual image, you can try to "swing" the pixels. There is a method based on rapid color change that causes the subpixels to actively switch, eliminating the charge that causes "ghosts." You can use specialized applications from Google Play, such as Screen Burn Fix or"OLED Tools".
The way these tools work is simple: they run a video cycle where the screen changes colors quickly (red, green, blue, white, black) and can take anywhere from 15 minutes to several hours, and it is important to leave the phone out of the room and keep it cool, because the array is very hot when it is running at full brightness.
β οΈ Warning: Do not leave your phone for "treatment" overnight or unattended for long periods. Excessive heating can damage the battery's adhesive layer or the matrix itself, causing the battery to bloat or yellow spots.
Alternatively, manual burnout: Turn on a video with fast-changing bright shots (like tech test clips on YouTube) at maximum brightness for 10-15 minutes. This is less effective than specialized software, but safer for the device's thermal mode. If after 2-3 sessions there is no result, further attempts may be useless.

Software "treatment" is effective only for temporary sticking (Image Retention). Physical burnout of organic matter (Burn-in) is impossible to fix software, you can only visually hide the defect.
Table of comparison of recovery methods
To make your defect control strategy easier to choose, we have compiled a basic method comparison table that will help you assess the risks and expected effectiveness of each approach, depending on the type of device you have and the extent of damage.
| Method | Efficiency in Retention | Efficiency in Burn-in | Risk to the device |
|---|---|---|---|
| Changing Static Content | Tall. | Absent. | No. |
| Annexes (flowercycles) | Very high. | Low (cloaking) | Medium (heating) |
| Engineering Menu (CIT) | Medium | Absent. | Low. |
| Replacement of the matrix | 100% | 100% | Loss of water protection |
It is worth noting that using the engineering menu (#6484##) allows you to run screen tests, but does not contain a "treatment" function, but it can check the uniformity of the response of the touch screen, which sometimes helps to identify hidden problems with the display controller, which are mistaken for burnout.
Secret combination for resetting calibration
Prevention and extension of the life of the display
The best treatment is prevention. To avoid residual images in the future, you should change your smartphone usage habits. First of all, you should avoid installing static widgets with bright elements on the home screen if you use AMOLED. The constant operation of the same pixels accelerates their degradation.
Use Auto Brightness. In modern Xiaomi smartphones, the light sensors work quite correctly. Manually twisting the brightness slider to the maximum indoors is a sure way to reduce the life of the screen. It is also recommended to periodically change the wallpaper so that the statics do not βgotβ on the same areas.
β οΈ Warning: Avoid using your smartphone in extremely low or high temperatures. Cold slows down pixel response, causing temporary plumes, and heat accelerates the chemical destruction of the organic layer.
Remember to update your firmware. MIUI and HyperOS updates often come with new display power management algorithms that can improve the performance of the residual image. If the problem occurs immediately after the update, try resetting (pre-backup), as conflict of old configuration files can cause artifacts.
When it is necessary to replace the display module
If none of the software methods worked, and the residual image remains clearly visible against any background, at any brightness and after rebooting, then the matrix resource is exhausted. In this case, the treatment is useless, you need to replace the display. On modern Xiaomi smartphones, the display is often assembled with a frame, which makes it easier to replace, but requires glass reglazing.
When contacting the service center, be sure to check the type of matrix you install. The original screens have the right color reproduction and support for DC Dimming technology (or its analogues), which reduces flickering. Cheap analogs (copies) can have the worst viewing angles and burn out even faster than the original.

When changing the screen, require a touchscreen check throughout the area, often after a poor replacement, "dead zones" or false presses on the edges appear.
The cost of replacement can be up to 40-60% It is important to consider the cost of repairing a new phone, and it is sometimes more profitable for older models to buy a new phone than to change the original display. Pro/Ultra), Replacing the original screen is fully justified and will return the device to a second life.
