Xiaomi’s flash is not just a bright LED, but a powerful tool to improve the quality of images in difficult lighting conditions. However, many users face problems: too bright or dim lights, incorrect operation in automatic mode, or complete lack of response to the press of a button. In this article, we will discuss all the ways to configure the flash on Redmi, POCO and Mi devices running MIUI 14/15, including hidden functions and professional tricks.
It’s important to understand that flash algorithms depend not only on the phone model, but also on the firmware version. For example, on the Xiaomi 13 Pro with Leica optics, flash settings are integrated into the advanced camera module, whereas on the budget Redmi Note 12, only basic parameters are available.
1. Basic ways to enable flash in standard camera mode
To start with, how to activate a flash in the Camera app. Most Xiaomi models have the same algorithm, but there are nuances for older versions of MIUI (up to 12.5).
Open the Camera app and look at the top toolbar, and you'll see the lightning icon, which is the flash switch, and click on it to select one of the modes:
- ⚡ Auto – The phone decides when to use the flash (recommended for beginners).
- 💡 On – flash is triggered with each shot (useful for shooting in complete darkness).
- 🌑 Off – flash turned off (use during the day or in good lighting).
- 🔦 Lantern - constant light (not available on all models, for example, there is a light on the light). POCO F5, but not on the Redmi. 10A).
On some devices (for example, Xiaomi 12T Pro) in Professional (Pro) mode, an additional option to manually adjust the flash intensity appears.
- Switch to Pro mode (usually swipe up or button on the menu).
- Slip on the zipper icon in the upper right corner.
- Flash power will appear – adjust from 1 to 10 (where 10 is the maximum brightness).
2. Hidden flash settings in the engineering menu
If you don't like the standard options, you can go to the MTK Engineering Mode or Qualcomm Service Menu, depending on the processor, which will allow you to fine-tune flash settings, such as changing the pulse duration or adjusting the white balance when shooting with a flash.
⚠️ Warning: Incorrect settings in the engineering menu can cause camera crashes. If you are not sure about your actions, skip this section.
Instructions for Qualcomm Snapdragon devices (most POCO and Xiaomi flagships):
- Open the Phone app and enter the combination: ##36446337###
- Go to the Hardware Testing → Camera section.
- Select Flashlight Test or Torch Mode.
- Here you can test the operation of the flash and change the parameters of Flash Duration (flash duration in MS) and Flash Intensity (intensity).
For devices on MediaTek (many Redmi budget line):
- Enter the phone app: ##4636##
- Go to Hardware Testing → Lights.
- Click Flashlight and select Custom Settings.

3. Flash setting for video shooting
Many users don’t know that Xiaomi can use flash not only for photos but also for videos.
- 🎥 On most models (Redmi Note) 11 Pro, POCO X5) The flash is only running in mode 4K@30fps Or lower. 1080p@60fps It shuts down automatically.
- 🔋 Long-term use of flash when recording video severely drains the battery and heats the case.
- 💡 Flash brightness in video mode is usually fixed (unregulated).
To turn on the flash when shooting the video:
- Open the Camera app and switch to Video mode.
- Click on the lightning icon in the top panel.
- Select On (some models have the option called a flashlight).
- Start recording - the flash will burn constantly.
💡
If the flash goes off after 30 seconds of recording, it's overheating protection. To get around the restriction, lower the video resolution to 720p or use an external light source.
4.Flash problems and their solutions
If the flash doesn't work or doesn't behave correctly, the causes can be both software and hardware, and let's look at the most common cases and how to fix them.
| Problem. | Possible cause | Decision |
|---|---|---|
| The flash is not manually switched on. | Failure in the Camera app | Clear the Camera Cache: Settings → Apps → Camera → Storage → Clear the Cache |
| The flash flash flashes arbitrarily | Conflict with battery optimization | Disable camera optimization: Settings → Battery → Battery optimization → Camera → No restrictions |
| The flash only works in flashlight mode. | Flash driver damaged | Update the firmware or reset the camera settings through the engineering menu |
| Too dim light | Contaminated LED or protective glass | Clean the flash module with an alcohol napkin (without pressing!) |
⚠️ Warning: If the flash stopped working after the phone crashed and cracks are visible on the camera module - don't try to disassemble the device yourself.In Xiaomi, the flash is connected to the motherboard through fragile plumes, and unprofessional repairs can damage other components.
5. Optimizing the flash for different shooting scenes
The right flash setting depends on the shooting conditions, and here are some recommendations for the most common scenarios:
- 🌃 Night portrait shooting: Use Car mode with Night mode on, flash will act as a filling light, and algorithms MIUI smooth out.
- 🎂 Photographing food in a restaurant: Turn off the flash and use Mode HDR. The flash distorts the natural colors of dishes.
- 👶 Photography of children or animals: Set the flash power on 30-40% (in Pro mode, so as not to blind the object.
- 📄 Scan documents: Turn on the flash at full power and use the Document mode in the Camera app.
For advanced users: if your Xiaomi supports RAW-Shooting (e.g. Xiaomi 13 Ultra), try the combination RAW + This will allow the laser to adjust the exposure in Lightroom without loss of quality.

6. Alternative applications for flash control
If the standard Camera app doesn't work, you can use third-party solutions that offer advanced settings, such as adjusting the color temperature of a flash or synchronizing with external flashes.
Top.-3 apps:
- 📱 Open Camera – Open source, Manual Flash Control, compatible with most models.
- 🎯 Footage – professional application with manual setting of power and duration of flash (paid, but there is a trial).
- 🔦 Flash Alerts 2 – allows you to use the flash for notifications (for example, blinking when calling).
⚠️ Note: Some applications (such as Manual Camera) require ROOT-rights to full access to flash settings. On Xiaomi devices with a locked bootloader, this can lead to loss of warranty.
7. How to extend the life of the flash module
The LED flash in Xiaomi smartphones is designed for 50,000-100,000 positives, but if used improperly, it can fail much earlier.
- ⚡ Do not use a flash as a flashlight for more than 5 minutes in a row - this leads to overheating.
- 🔋 Avoid flash shooting with low battery charge (less than 20%).
- 🧊 Do not expose your phone to extreme temperature changes immediately after using the flash.
- 🛠️ Regularly update the firmware in new versions MIUI Optimized flash control algorithms.
Xiaomi 12S Ultra and later devices use a two-tone flash (warm + cold LED) that heats less and lasts longer. If you have an older model (for example, Redmi Note 9), try not to use the flash at maximum power.
💡
Frequent use of the flash at full power reduces its life by 2-3 times, the optimal mode is 50-70% brightness if necessary.
