Owners of Xiaomi, Redmi and POCO smartphones often face the unpleasant phenomenon: a screenshot on the screen of the device looks perfect, but when viewed in a gallery or sent to the messenger, the image becomes noticeably darker. It is not a matrix defect or a defect of a particular instance of the phone. The problem lies in the image processing algorithms that the company is actively implementing in the shell of MIUI and HyperOS.
The main reason lies in technology. HDR-When you take a picture of the contents of the display, the system tries to maintain dynamic range, but when played back to standard. SDR-screen (or applications that do not support the HDR) This is especially noticeable if you have Ultra enabled. HDR or activated reading mode.
To make matters worse, many popular apps like Instagram or WhatsApp compress the image further when it is uploaded and apply their color correction filters, making the dark screenshot even fadier. In this article, we will analyze the technical causes of the phenomenon and suggest working ways to fix the situation without loss of quality.
HDR technology and screen capture in MIUI
Xiaomi’s current flagship and mid-range smartphones feature displays that support extended dynamic range, allowing for very bright highlights and deep shadows at the same time, but the standard screenshot format (usually PNG or JPG) has not historically been designed to store such a wide range of brightness.
When you take a screenshot at the moment it is displayed HDR-content (e.g. high quality YouTube videos or games with support) HDR10+), The system stores the metadata of brightness. When viewing such a file on a device without adequate support or in a simple viewer, this metadata is interpreted incorrectly, and the image appears underexposed.
Xiaomi engineers have implemented a mechanism that tries to make up for this difference, but often the algorithm works backwards, darkening the final file to "keep the details in the lights." This is a software feature, not a physical breakdown.
- 📱 Format PNG It is better to save details, but filesize can be more.
- 🎨 Dolby Vision Mode Often Conflicts With Standard Screen Capture.
- 🔋 Energy saving can limit the brightness of the exchange buffer.
⚠️ WARNING: If you take screenshots for further editing in Photoshop or Lightroom, be sure to check the histogram.Inflated brightness on your phone screen can hide the real under-lighting of the file.
💡
Use the built-in MIUI editor immediately after you create a screenshot to force the exposure to be raised until the file has been compressed by the messenger.
The Impact of Night Mode and Dark Themes
Another factor that affects the perception of brightness of screenshots is the global dark theme of the system. The MIUI shell implements a function called Dark Mode 2.0, which inverts the colors of not only the interface, but also some elements of the web pages. When you create a screenshot, the system can capture already inverted, darkened pixel values.
This is especially true at night, when the automatic brightness control is active, and if the light sensor thought it was dark when it captured the screen, it could have software-generated the brightness of the display, and the screenshot is saved for these software adjustments, rather than the physical brightness of the backlight.
Also worth mentioning is the Reading mode (Eye Comfort), which adds a warm yellow filter, which can be baked into the image when you take a screenshot, making it dull and dark compared to the original content.
For users who care about accurate color reproduction, it is recommended that all automatic controls be turned off before creating important screenshots, which will ensure that the image is “clean” without the intervention of system filters.
- 🌙 Night mode reduces the overall brightness of the interface.
- 👓 Reading mode adds yellowness and reduces contrast.

Display settings and color profiles
The key parameter that determines how your screenshot will look is the color profile you choose. The Settings menu → Screen → Color scheme usually provides options for “Saturated”, “Standard” and “Classic”.
The Vivid profile often uses an extended color space that loses brightness when converted to standard sRGB (the format for most social networks), and if you choose a Classic or Standard profile, the difference between what you see and what you get in the screenshot will be minimal.
DC Dimming (or Anti-flicker) also plays an important role, regulating the brightness of the screen not by changing the backlight power, but by the frequency of the flicker. Another phone’s camera or some screen capture algorithms may misread the image from a screen operating in low frequency mode, resulting in dark bars or a general darkening of the frame.
| Parameter | Impact on screenshot | Recommendation |
|---|---|---|
| Color profile | The saturated darkens when converting | Use the Standard |
| DC Dimming | May cause artifacts of brightness | Turn off for screenshots |
| Autobrightness | Changes brightness at the time of capture | Lock it with a slider |
| TrueColor | Adjusts the white balance | Leave it on. |
| Frequency of update | 120 Hz can produce lubrication | Doesn't affect brightness. |
Remember that different Xiaomi models (e.g. Mi 11 vs Redmi Note 10) use different types of matrices (AMOLED vs IPS), and the color profiles may behave differently.
Problems with specific applications
Sometimes the problem is not with the system, but with the optimization of the app. Some programs, especially banking clients or streaming services like Netflix, use DRM protection. When you try to take a screenshot of such a screen, you either get a black image or an image with a very low brightness and distorted colors.
In the browser Chrome or MI Browser can be activated mode traffic saving or night mode of the browser itself, which regardless of the system settings darkens the web pages.
Social media also makes adjustments. If you take a screenshot inside the Instagram app and then send it there, there's a double compression. JPEG compression algorithms often cut bright areas, making the picture dim.
⚠️ Attention: Content Protection Apps (DRM) They can deliberately distort screenshots to prevent piracy.

Instructions: How to fix dark screenshots
If you are not happy with the quality of the images you are saving, you can try a series of steps to set up the system, the first thing you need to do is check the developer's settings, although in new versions of HyperOS, some items may have moved or disappeared.
Try turning off adaptive brightness before an important capture, manually set the value to a comfortable level (about 60-70%), take a screenshot and compare the result, and temporarily turn off all image enhancers in the gallery.
☑️ Checklist settings before screenshot
There is also a method of resetting the screen to factory settings if the problem occurs after the firmware update. Go to Settings → Screen → (bottom) Reset screen settings. This will return all color gamuts and calibrations to their original state.
In some cases, cleaning the cache of the system component responsible for the UI helps. This will require access to a hidden menu, but be careful: inexperienced users are better off limiting themselves to standard methods.
- 🛠 Reset the screen settings in the system menu.
- 📉 Turn off all blue light filters.
- 🔄 Update the Gallery app through GetApps.
💡
The most effective way is to use the Standard profile and manually fix the brightness before the shot.
Third-party solutions and alternatives
If Xiaomi’s built-in tools don’t work, you can always turn to third-party software.Screenshot apps from the Play Market often have their own capture algorithms that ignore the system’s brightness limits.
Popular programs like Screen Master or Screenshot Easy allow you to adjust the save format, compression quality, and even automatic color correction immediately after capture, and they can force the brightness of the final file to improve.
Another option is to use the Long Screenshot feature, which sometimes works differently when you run a long image, and the resulting brightness may be different from a normal single shot, which is not a guaranteed method, but in some versions of MIUI it works as a workaround.
For professionals who need perfect color rendering, it is recommended to use USB image output on a PC followed by capture via OBS or similar software, although this requires having a computer at hand.
