Users who are first-time users of MIUI or HyperOS interfaces often wonder about the location of LED backlight control. Unlike older button phones where the flashlight and flashlight could have separate switches, in modern Xiaomi smartphones, all control is concentrated in software. Physically, the LED is located on the back of the device, usually in a block with main lenses, but it can only be activated through the screen.
The Camera application interface is designed to keep the basic functions at hand, however, some settings can be hidden in the additional menus. LED-The flash has a dual function: it lights objects when you're shooting, and it works like a flashlight when you're off. Understanding the logic of how the interface works will allow you to quickly find the controls you need in any situation.
In this article, we will discuss in detail where the power button is, how to switch modes and what to do if the indicator has stopped responding to commands. It is important to know that some Redmi and POCO models may not have a physical flash, replaced by software emulation or screen lighting. Let's understand the nuances of the optical system of your gadget.
Location of the control button in the interface
The default control panel in the Camera app is at the top of the screen. To activate the flash, you need to swipe your finger over the top panel from left to right or find the appropriate icon. The standard position of the control is the top left corner, next to the resolution and HDR settings.
When you press the lightning icon, the mode switch cycle goes through several states. Usually the system offers a choice between automatic mode, forced on and off. Some versions of the MIUI shell also have a Stop frame mode or strobe that flashes light at a certain frequency.
💡
If the flash icon is grey or crossed out, then at the moment the selected shooting mode does not support the use of LED-backlighting, for example, when the Portrait mode is active on some models.
It's worth noting that the location of the elements can vary slightly depending on the orientation of the smartphone. In horizontal mode, the toolbar often moves to the side of the screen, which is ergonomic for shooting with both hands, so that the right thumb can quickly get to key settings.
- 📸 Automatic mode: flash only works in low light, determined by algorithms.
- ⚡ Forced turn on: LED lights constantly while aiming and makes the picture brighter.
- 🚫 Turned off: flash will not work even in complete darkness.
- 🎬 Video Mode: Separate setting for permanent light when recording rollers.
LED lighting modes
Modern camera modules in Xiaomi devices support various scenarios for using the built-in LED. The basic mode "Auto" is the most reasonable choice for everyday shooting, as artificial intelligence algorithms analyze the scene and decide whether additional light is needed.
For video, the logic of the work changes, so when you switch to video recording mode, you have a separate button for controlling the light, which often looks like a lightning bolt that says "Video." LED-The diode burns continuously throughout the recording, which can significantly discharge the battery and heat the device body.
⚠️ Warning: Prolonged recording of video with flash on can cause critical heating of the camera module.If you notice a temperature warning on the screen, immediately stop recording to avoid damage to the sensor.
There's also a hidden or rarely used Stop Frame (or strobe) mode that turns a flash into a high-frequency flashing beacon, a feature that can be useful in emergencies or for attracting attention, but is not related to photography.
In professional shooting modes (Pro), light control can be made into a separate exposure settings menu, where the user gets full control of shutter speed and ISO, and flash is often blocked, as manual settings involve using external light or a tripod.
Setting up additional camera functions
In the back of the Camera app settings, there's a menu called "Additional Features," where you can find a fine-tuning of the flash behavior. To get there, click on three horizontal bars in the corner of the screen and select a gear, and there are switches that affect the optical system in different conditions.
One useful feature is Screenlight or Screen Flash. If the main LED is damaged or you want a softer light, you can activate a mode in which the screen lights up white when you take a selfie. This is true for a front-facing camera that doesn’t have its own. LED-component.
You can also find noise reduction settings in this section when you use a flash, and when you turn on the lights in the dark, the camera can take a picture of artifacts, and software filters help to smooth this effect out, but it's worth remembering that any digital improvements reduce the detail of the final image.
| Function | Description | Influence on photo |
|---|---|---|
| Auto-flare | Illumination analysis | The natural balance of light |
| Persistent light | It burns all the time. | Increases contrast, can blind |
| Screen flash | Light from the display | Soft diffused light for selfie |
| Slow-motion | A series of pulses | Creates a stroboscope effect |
☑️ Checking the light settings
Using the flash in night mode
Night Mode on Xiaomi smartphones works on the principle of complex mathematical processing of several frames with different exposure. LED-flashes are often contraindicated, as sharp pulsed light destroys the algorithms of gluing frames. The camera can automatically turn off the LED when activated "Night».
If you force a flash on in night mode, the result can be unpredictable: the foreground will be overlit and the background will remain black. Optical stabilization combined with long night exposure is designed to capture ambient light, rather than reflected from objects close by.
⚠️ Warning: Do not use the flash to capture reflective surfaces (mirrors, windows) in the night mode. This will create a powerful illumination that completely spoils the frame.
For high-quality shooting in the dark, it is better to rely on sensor capabilities and software stabilization, holding the phone still. If there is critically little light, it is better to use an external light source or a “Bright Night” mode that is specifically sharpened to work without pulsed backlight.

Problems with the outbreak and how to solve them
When the camera is running but the flash is not lit, it can be caused by software failure or physical damage. The most common problem is application conflict: if the flashlight is busy with another process, the camera will not be able to access the hardware module. Close all background applications and try to restart the device.
In rare cases, the failure occurs at the driver level of the Android operating system, which can help clear the Camera cache. To do this, go to the phone's settings, find the Apps section, select Camera, and click Clear Cache. This action will not delete your photos, but reset temporary settings files.
If the flash flash flash flashes once and goes out or lights dimly, it may indicate power problems or oxidation of contacts inside the enclosure, in which case the software methods are powerless, and a diagnostic at the service center is required, and it is also worth checking whether the power saving mode is on, which can block energy-intensive functions.
- 🔄 Reboot your smartphone to reset temporary system errors.
- 🧹 Clear the Camera app cache through Android settings.
- 🔋 Turn off the energy saving mode if it is active.
- 🛠 Check for system updates in the About Phone menu».
💡
If the flash doesn’t work after the camera resets and resets, it’s likely that the problem is hardware in nature and requires a module replacement.
