Xiaomi’s current smartphones are equipped with sophisticated image processing algorithms designed to improve the quality of images in low light conditions. However, automation does not always work correctly, and instead of a detailed frame, the user gets a blurry image with unnatural brightness. The question of how to turn off the night mode on the Xiaomi Redmi Note 9 Pro becomes relevant for those who prefer to control each shooting parameter by hand.
Often the problem lies not only in the camera’s software, but also in the display settings, which can distort the perception of color, creating the illusion of an on filter. Device owners are faced with an obsessive desire to “improve” the picture where it is not necessary. Understanding the mechanisms of the AI algorithms will allow you to take control of the device in your own hands and avoid unwanted artifacts.
In this detailed guide, we will take a look at all aspects of nighttime photography on your gadget, we will look at the regular shutdown tools, the nuances of working with MIUI firmware and possible hardware limitations, you will learn to distinguish between software bugs and sensor features, which will make the process of photographing more predictable and enjoyable.
Features of night mode in MIUI
The MIUI nighttime imagery feature is based on multi-frame synthesis technology, where the camera takes a series of different exposures in a short time, and then the image processor combines them into a single file, which allows you to pull the details out of the shadows and not "light up" bright areas, but the process takes time and immobility of the device.
The Redmi Note 9 Pro features a Quad Camera system that is powered by a high-resolution sensor, and AI algorithms automatically analyze the scene and, if they detect a lack of light, can suggest switching to a special mode or activating long shutter speeds, which is the automation that often annoys power users who want to be natural.
⚠️ Warning: Forced shutdown of system algorithms through the engineering menu can lead to unstable operation of the Camera application and the appearance of artifacts in all images, not only night shots.
It is also worth considering that optical stabilization (if supported by a specific sensor modification) works in conjunction with the software. When software improvements are turned off, the stabilization load may increase, which will require a firmer hand when shooting, and understanding these relationships is critical to achieving quality results.
Disabling night mode in the standard application
The easiest and safest way to control the function is in the Camera interface, where when you run the application in low light conditions at the top of the screen or in the mode menu, you may see a moon icon or the words “Night” in the menu. To deactivate this mode, you just need to touch the corresponding icon, returning the camera to the standard “Photo” mode.
If automatic switching happens too often, it’s worth checking the AI settings. The top of the camera interface often has an icon labeled AI or a magic wand, pressing it turns off the script analyzer, which initiates the transition to night mode, and then the camera will use standard exposure settings, ignoring low light levels.
You can use professional mode to fine-tune it, and by switching to the Pro or Manual section, you have full control over your shooting settings, and you can manually set the ISO and shutter speed, eliminating any interference from Xiaomi's automatic algorithms.
☑️ Setup of the camera for manual shooting
You get a raw image that may require further processing in the editor, but this approach allows you to maximize flexibility and predictability in difficult light conditions.
Setting up display parameters and reading
Users often confuse the camera's night mode with the read mode or "paper" screen mode, which makes the image yellow to reduce eye strain.If your Redmi Note 9 Pro constantly displays content in warm colors, the problem may be with the display settings rather than the camera.This is a common mistake that misleads many owners.
To check and disable this feature, go to the main settings of the device. Find the Screen section and then select Read Mode or Paper Mode. Here you can completely turn off the function or set it to activate on a schedule. Make sure the activation slider is in the off position.
Also worth paying attention to is the Dark Mode 2.0 feature, which, although it doesn’t turn the screen yellow, inverts the interface colors, which, when combined with certain wallpapers, can create a “night” look of the system, which can be turned off through the notification curtain or in the Topics → Settings menu.
Why does the screen turn yellow while reading?
Another parameter that affects color reproduction is the color scheme. In the Color scheme menu, select either Standard or Saturated, avoiding the warm balance options. This will return the colors on the Redmi Note 9 Pro screen to factory calibration values.
Using the Profi mode for full control
For those who want to completely eliminate the automatic on-night shooting, Pro Pro mode is the perfect solution, in which the camera ignores script analyzers and works strictly according to user-defined parameters, and this is especially useful when shooting urban landscapes at night, where automation often “overcooks” light spots.
The key here is shutter speed, and if you set the shutter speed to 1/60 or 1/100 of a second, you're guaranteed to avoid the long exposure that nighttime is like, but you're going to have to raise the ISO, which can lead to digital noise in the image.
| Parameter | Recommended value | Impact on the photo |
|---|---|---|
| Excerpt (S) | 1/60 - 1/200 | Freezes movement, eliminates lubricants |
| ISO | 400 - 1600 | It increases brightness, adds noise. |
| White balance (WB) | Auto or 4500K | Corrects the color temperature |
| Focus (MF) | Infinity | For shooting distant objects |
Using RAW in professional mode also provides more post-processing options. DNG files save more information about light and color, allowing you to pull out details in the editor without loss of quality, which is often more effective than built-in night shooting algorithms.
💡
Save your images in RAW if you plan to process them in Lightroom or Snapseed, which will give you more freedom in noise correction than a ready-made JPEG from night mode.
Third-party apps and Google Camera
If Xiaomi’s regular app doesn’t meet your nighttime control needs, a ported version of Google Camera (GCam) is a great solution. Google’s HDR+ processing algorithms often work softer and more natural than standard MIUI solutions, especially on Samsung’s sensors installed in the Redmi Note 9 Pro.
Third-party applications like Open Camera or ProCam X can completely disable all kinds of automatic enhancements, allowing you to prioritize shutter speed or matrix sensitivity, ignoring the system's suggestions about going to night mode.
⚠️ Note: When installing modified versions of cameras (GCam) from unverified sources, there is a risk of personal data leakage or malware infection of the device.
To install GCam on Redmi Note 9 Pro (codename curtana) you need to find a version compatible with the Snapdragon 730G processor. The wrong version may work unstable or not run at all. Configuration files (.xml) will help customize the application to the specifics of a particular sensor.
Solving Software Problems
In some cases, night mode may stick or turn on spontaneously due to a software failure in the camera application. If simple settings do not help, it is worth trying to clear the app cache. To do this, go to Settings → Apps → All apps → Camera → Memory and select Clear the cache.
A more radical but effective method is to reset the app to factory settings, which will return all camera settings to their original state by removing any conflicting configurations, and note that your personal photos and videos will not be deleted, only the configuration of the program will be affected.
If the problem persists after resetting, you may need to update the firmware. Xiaomi regularly releases patches that fix camera errors. Check for updates in the About Phone → MIUI version.
💡
Cleaning the cache and data of the Camera application solves 80% of problems with incorrect switching of shooting modes without losing personal files.
