The flash on Xiaomi Redmi smartphones is not just a light source for night shots, but a full-fledged tool that can transform your photos. However, many users face difficulties when turning it on: the button is inactive, the flash is not working at the right time, then it is not on the menu at all. In this article, we will discuss all possible ways to activate the flash from basic to hidden MIUI functions, and also explain how to avoid typical errors.
Redmi's feature is that the manufacturer often changes the layout of the controls depending on the model and firmware version. For example, on the Redmi Note 12 Pro+, the path to the flash settings is different from the Redmi 10A. We took these nuances into account and prepared universal instructions that will suit most devices in the line, and you will also learn how to use the flash not only for photos, but also as a flashlight, and also in video shooting mode.
Basic method: enabling the flash in the Camera app
The most obvious method is to activate the flash directly in the interface of the standard Camera application, but even here there are pitfalls: on some Redmi models, the flash button may be hidden or not work properly due to power saving settings.
To turn on the flash:
- 📱 Open the Camera app (the icon is usually on the home screen or in the app menu).
- 🔍 In the top toolbar, find the flash icon (stylized lightning) ⚡). In some models, it can be hidden under the button More or ⋮.
- 🔄 Tap the icon to switch modes: Off. — flash will not work. Auto — smartphone will decide whether to flash. On. — flash will work with each shot.
If the flash icon is missing, check if Professional mode is activated (it can turn off the automatic flash). MIUI The button appears only after the first click on the screen to focus.
💡
On the Redmi Note 11 Pro and later, the flash button can hide when the screen is horizontally oriented. Turn the phone vertically to see it.
2. Flash like a flashlight: quick turn on from the notification panel
The flash on Xiaomi Redmi can be used not only for photos, but also as a full-fledged flashlight, which is convenient when you need to light the road or find an object in the dark.
Instructions:

- 🔘 Touch the icon once to turn on the flashlight. Re-pressing it will turn it off.
On some models (e.g. Redmi 9A), the flashlight may not work if the battery level is below 15%, which is done to save energy. It is also worth remembering that prolonged use of the flashlight warms up the case of the smartphone and can reduce the life of the LED.
Video flash: why it doesn’t work and how to turn it on
Many Redmi users have a problem: the flash works great for photos, but refuses to turn on when recording video, because of the limitations of MIUI firmware, which block constant backlight during shooting due to overheating.
To make the flash work in the video:
- 🎥 Open the Camera app and go to Video mode.
- ⚡ Click on the flash icon (if it is active) and select the On mode..
- ⚠️ If the button is inactive, try: Switch to Professional Video Mode (if any); disable Stabilization in the camera settings (sometimes it conflicts with the flash); install a third-party shooting app (such as Open Camera).
Why Xiaomi is limiting flash when video is on?
On Redmi Note 10 Pros and older, there's a hidden feature called a flash pulse in video, which is activated through an engineering menu (which we'll talk about below) and allows the LED to blink at a given frequency, mimicking a strobe, which is useful for shooting dynamic scenes in the dark.
4. Hidden settings: engineering menu and codes for flash control
If standard methods don’t work, you can try activating the flash through an engineering menu or special commands, which is suitable for advanced users, as improper actions can disrupt the camera.
Instructions for accessing hidden settings:
- 📞 Open the Phone app and enter the code: ##36446337## This will open the hardware component testing menu (some firmware may not work on some firmware).
- 🔧 Select a point. LED Flashlight (name depends on the model).
- 🔄 Turn on the flash test and check it, and you can adjust the brightness and the frequency of the flash.
For Redmi models based on Qualcomm Snapdragon (for example, Redmi Note 12 Pro+) works alternative code:
##7594##It opens the camera control menu where you can manually turn on the flash even if it is locked by the system.
⚠️ Note: Do not change other options in the engineering menu unless you are sure of their purpose. For example, an incorrect setting of the Sensor Calibration can cause autofocus to fail.
5.Flash problems: why it doesn't work and how to fix it
If the flash is not triggered by any of the above methods, the causes can be both software and hardware.
| Problem. | Possible cause | Decision |
|---|---|---|
| Flash button inactive | Energy saving regime or MIUI restrictions | Turn off Battery mode → Energy saving or reset camera settings |
| The flash flash flashes, but does not shine constantly | Failure of the LED or driver | Check the engineering menu or contact the service |
| Flash only works in some applications | Restrictions on access rights | Give permission to use the camera and flashlight in Settings → Apps |
| The LED is glowing dimly. | Pollution of the lens or wear | Clean the module with alcohol or replace the LED |
If none of these methods worked, try resetting the camera settings:
- Go to Settings → Applications → Camera → Storage.
- Click Clear Data and Clear Cache.
- Reboot your smartphone.
☑️ Diagnostics of outbreak failure
6. Third-party flash control applications
If standard MIUI tools don't suit you, you can use third-party utilities, which offer advanced features: brightness adjustment, strobe, timer control, and even remote activation via SMS.
Top.-3 applications to work with the flash on Xiaomi Redmi:
- 📌 Flash Alerts 2 flashes when incoming calls and notifications. Supports color and frequency settings.
- 📌 Tiny Flashlight + LED — allows you to use the flash as a flashlight with adjustable brightness and blinking mode.
- 📌 Flash Notification 2 - Advanced settings for notifications + vibration + sound).
Before installing, check compatibility with your Redmi model.Some applications require permission to access the camera and may not work on MIUI firmware older than version 13 due to security limitations.
⚠️ Note: Applications from unverified sources may contain malicious code that uses the flash to transmit data (Li-Fi method).Install software only from Google Play or the official Xiaomi store.
7.How to extend the life of a flash LED
The flash LED is one of the most vulnerable elements in the camera, and when used intensively, it can fail in 1-2 years.
- ⏱️ Do not use a flashlight for more than 5 minutes in a row - let the LED cool down.
- 🔋 Avoid flashing when battery is low (below 20%).
- 🧹 Clean the camera module of dust and dirt regularly (use a soft brush or compressed air).
- 🌡️ Do not overheat your smartphone (for example, do not leave it in the sun with the flashlight on).
On the Redmi models with AMOLED-screen (e.g. Redmi) K50) You can use a Screen Flash instead of an LED, it's less bright, but it's completely safe for the hardware.
💡
The flash LED is designed for ~50,000 inclusions. When you use it intensively (for example, a flashlight for 10 minutes every day), the resource is exhausted in 1-1.5 years.
