Xiaomi’s current smartphones are equipped with advanced AI systems for processing photos, but automatic algorithms sometimes work incorrectly. Users often encounter an intrusive pre-flare function that is designed to narrow the pupils, but in practice only prevents them from taking pictures. Instead of instantaneously capturing a moment, you have to wait for a series of pulses, which often leads to blurred frames and missed seconds.
Known as Red-eye reduction, this technology was the standard for compact cameras of the early two thousandth year, but in the era of night mode and optical stabilization, it has lost its relevance. On devices with a MIUI shell or a new HyperOS, this option can be turned on by default in certain shooting scenarios, annoying the owner. To regain full control of the camera, you need to manually change the settings in the app menu.
Disabling this feature will not only speed up the process of taking pictures, but also save battery power, since the screen and flash module will not waste energy. In this article, we will discuss in detail where to look for the switch, how it affects the final image quality, and what alternative methods exist to combat the red eye effect in post-processing.
Why the Red Eye Effect Happens and How the Flash Works
The red eye effect occurs when light from the flash bounces off the retina of the eye, saturated with blood vessels, and returns to the camera lens. This physical phenomenon is especially noticeable in low-light conditions, when a person's pupils are dilated, letting more light into the eyeball. Xiaomi's algorithms try to prevent this by emitting a series of short pulses in front of the main frame.
The logic behind the system is simple: pre-flares cause the pupils to shrink reflexively, reducing the area of the reflective surface. However, in reality, this process takes time for the person being photographed to blink or change the position of the head, which is why many prefer to turn off this option completely, relying on software color correction after shooting.
It is worth noting that on the flagship models of the Mi and Xiaomi series with advanced sensors, the need for mechanical narrowing of the pupils is minimal. Modern image processing (ISP) processors are able to automatically remove the redness during the rendering stage of the photo without requiring preliminary preparation of the subject.
💡
Use external lighting or ask the subject to look toward the light source before the frame – this will narrow the pupils naturally without using a flash.
Step-by-step: disabling in the standard Camera app
To start, you need to run the standard Camera app, which is pre-installed on all smartphones of the brand. The interface may vary slightly depending on the version of the operating system, but the basic navigation logic remains the same for all devices. First step, open the application and make sure that you are in the “Photo” or “Portrait” mode, where you can work with the flash.
Then, look at the top of the screen where the lightning icon is located. When you click on it, you'll see a drop-down menu with the flash options: "Auto", "On", "Off" and "Red Eyes Suppression." It is the last item, often denoted by the eye or sparkling zipper icon, that is responsible for a series of pre-impulsions. Select "Off" or "Auto" mode to remove the intrusive blink.
☑️ Checking flash settings
It is important to understand that settings can be reset when switching between shooting modes. For example, if you choose Night or Portrait mode, you will have to recheck the flash state, since MIUI algorithms can automatically activate red eye suppression for these scenarios.
💡
Auto mode is often the best choice, as the system decides whether a pre-flash is needed based on the analysis of the scene’s illumination.
Settings in Portrait and Night mode
Portrait and Night modes have their own processing algorithms that can ignore the global flash settings. In Portrait mode, the smartphone tries to mimic a bokeh and often forcibly turns on a flash to illuminate the face if it considers the lighting insufficient. Here, the flash settings menu is usually hidden deeper in the interface or called by a long tap on the zipper icon.
Night Mode is even more challenging: to create a high-quality, long-exposure shot, any movement, including flashing from a pre-flash, can ruin the photo. If you notice that in this mode the camera continues to blink in front of the main frame, check the artificial intelligence settings. Sometimes switching to manual Pro mode, where you get full control of exposure and flash settings.
Some users have noted that after updating the firmware settings can “fly” or change the logic of work. If you do not find the right switch in the standard menu, try to clear the cache of the camera application through the system settings. This will not delete your photos, but return the application parameters to factory values, which often solves software glitches.
Secrets of the Pro regime
Use of third-party applications for shooting
If the standard Xiaomi app seems too limited or continues to behave unpredictably, a great alternative will be third-party cameras from the Google Play store. Programs like Open Camera or ProCam X provide detailed control over each device parameter, allowing you to completely ignore the manufacturer’s system limitations.
In these applications, flash settings are displayed on the home screen and work in a completely predictable way. You can set a strict ban on the use of the flash or adjust its behavior as you wish. In addition, third-party software often offers more flexible save format settings, which is useful for later processing.
The installation of an alternative camera is especially relevant for older smartphone models, where MIUI algorithms can run slower. Lightweight applications provide faster start-up and instant response, which is critical in reportage photography.
Table of comparison of flash modes
To better understand the difference between the options available, let’s look at their characteristics in a comparative table, which will help you choose the optimal mode for specific shooting conditions and finally decide on the settings.
| Flash mode | Description of behaviour | Impact on the battery | Recommended use |
|---|---|---|---|
| Automobile | The system decides when a flash is needed. | Average. | Everyday shooting, parties |
| Included. | The flash always works when pressed. | High. | Filling light during the day, macro photography |
| Suppression | A series of pulses before the main frame | Very high. | Group photos in the dark (rarely) |
| Off. | The flash is never used. | Minimum | Concerts, museums, night photography |
As you can see from the table, red eye suppression is the most energy-consuming mode. Continuous use of this mode can significantly reduce the battery life of a smartphone during the day. For most scenarios, “Auto” or “Switched off” mode is the more rational choice.
Alternative methods to eliminate red eyes
If you do get a red-eyed shot, don't rush to delete it. Modern galleries and editors can fix this defect in a few seconds. The standard Gallery app on Xiaomi smartphones has a powerful editor built in that automatically recognizes faces and suggests eliminating the effect.
To do this, open a photo, click Change, and find the Retouch tool or the Red Eyes tool. AI will neatly replace red with a natural black or dark brown color, preserving the glare and texture of the iris. This method often produces a more natural result than trying to prevent the effect hardware.
You can also use third-party apps like Snapseed or Adobe Lightroom, which have local correction tools that allow you to point-to-point reduce red channel saturation in the pupil area, which is a professional approach that gives the best result for important photos.
💡
Software-based red eye removal in an editor is often more effective than a pre-flash, as it does not require re-shooting and does not scare the subject of the photograph.
Possible problems and solutions
Sometimes users are faced with a situation where the flash mode switch is inactive (gray) or disappears from the menu.This may be due to activated Do Not Disturb mode or special energy saving functions. Check if you have an energy saving mode that limits the flash to extend the life of the battery.
Another reason could be that the device overheats, so if the smartphone gets hot, the system can block the use of the flash to prevent damage to the components, let the device cool down and the functionality recovers, and make sure that the Camera app has all the necessary permissions in the system settings.
⚠️ Attention: If the flash continues to flash chaotically even when it's off, it could indicate a software failure or a malfunction of the light sensor.Try to restart your smartphone or reset your camera settings.
In rare cases, the problem lies in damage to the plume or the flash module itself, especially if the phone has previously been hit or moisture. If software methods do not help, it makes sense to contact an authorized service center for diagnosis.
