Xiaomi smartphones have long since ceased to be just devices for calls, becoming universal tools for solving everyday tasks. One of the most popular features remains a built-in flashlight, which may be needed in a dark entrance, when searching for keys or during a sudden power outage. Users often look for a quick way to activate, not wanting to waste time searching the menu.
MIUI and the new HyperOS have many flash scenarios that go far beyond just lighting: you can set up automatic call activation, use it as a strobe or even turn the screen into a soft light source, and the developers have implemented flexible settings to adapt the diode to any needs of the owner.
In this article, we will take a look at all the known activation techniques, from standard gestures to hidden engineering capabilities. You will learn how to adjust the timer, change the color of the screen backlight and solve typical problems with the module. Understanding these nuances will help you to maximize the potential of your gadget Redmi or POCO.
Standard ways to activate through curtain and buttons
The most obvious and common method that most Android smartphone owners are familiar with is using a control center, which requires swiping your finger from the top edge of the screen down to open the notification curtain. In the menu that opens, you should find the icon designated by the flashlight symbol and touch it. If the icon does not appear on the first screen, try swiping left or pressing the edit button to add it to quick access.
An alternative and often more convenient way is to use physical control buttons. The default MIUI shell has a feature that allows you to turn on the flash by double-pressing the lock button when the device is in sleep mode, an option that is especially useful when you need to quickly light up the space without unlocking the phone or wasting charge on the interface.
However, you should note that double-pressing can conflict with other system commands, such as starting the camera. If the function does not work, you need to check its status in the settings. Go to Settings → Additional Features → Flashlight and make sure that the switch is activated. You can also change the sensitivity of the sensor or turn off the function if it interferes with you.
💡
To light up the flashlight instantly, make sure that the screen lock settings do not have too long delay in the response to double pressing.
Control of the flash through the Camera app
The built-in camera app on Xiaomi smartphones has advanced functionality that allows you to use the flash not only for photography. In photo or video mode, the lightning icon in the upper corner of the interface serves as a switch between the diode modes. Pressing it puts the flash into a constant glow mode, which is convenient for video shooting in low light conditions.
In addition, the camera's optional feature menu often hides a separate flashlight mode, which differs from the system mode in that it can offer additional brightness settings or color temperature if the model's hardware allows. Some flagship Xiaomi models support light intensity adjustment directly from the shooting interface.
This is because the device's processor continues to process video streams or keep the camera modules active, and for short-term lighting, it's better to use system tools, and leave the camera for creative tasks.

Customization of gestures and additional functions
The MIUI shell is famous for its customization, and flashlight control is no exception. You can find the option to turn on the flashlight when you hold your phone to your ear during an incoming call, which is useful in situations where your hands are busy and it is difficult to find a companion in the dark.
It is also possible to activate the flashlight by shaking the device, although this feature is more often associated with turning on the screen, in some use cases it can be reassigned or supplemented with the corresponding script through third-party launchers.
☑️ Checking the flashlight settings
For users who often use navigation at night, setting up the automatic lighting of the screen or flash when starting maps is relevant. Although this is difficult to implement with regular means, there are automation scenarios that can be configured through the built-in Auto Tasks app, which will allow the phone to respond to the navigator launch by turning on the light source.
⚠️ Warning: Excessive use of the flashlight function may result in a quick battery drain if you frequently take calls during the day.
Use of the screen as a light source
Not everyone knows that the screen of Xiaomi smartphone can serve as an effective source of diffuse light. Unlike the LED flash, which gives a narrow and bright beam, the screen illuminates a large area, which is ideal for reading or searching for items in a bag.
Some design themes and widgets have ready-made solutions for turning the display into a flashlight, so you can download a picture of all white and open it through the gallery to the full screen, which creates the effect of a soft lamp that does not blind your eyes, but gives enough light for comfortable activities up close.
There are also specialized apps from GetApps or Google Play that display different color schemes and flashing modes, which can mimic a candle, a fire or an alarm, which consume less power than video, but still require active display.
💡
Screen lighting is ideal for reading fine text or searching in a bag, as it gives a soft, non-cutting light.
Comparison of methods and energy consumption
Different ways to activate a flashlight have their own power consumption and impact on the device, and understanding these differences will help you choose the best option for a particular situation and extend the battery life of the smartphone.
Below is a table comparing the main characteristics of different flash usage methods on Redmi and POCO devices:
| Activation method | Brightness | Impact on the battery | Heating the hull |
|---|---|---|---|
| System flashlight (LED) | Tall. | Average. | Notable. |
| Screen (white background) | Medium | High. | Weak. |
| Camera (video) | Tall. | Very high. | Strong. |
| A flash on a bell | Tall. | Depends on the duration. | Moderate. |
As the data shows, the use of LED-The screen consumes a significant amount of energy even in a static white image due to the operation of the matrix and backlight. Therefore, for long-term use, it is better to have a power bank or charger on hand.
Solution and troubleshooting
Sometimes users are faced with a situation where the flashlight stops turning on or is unstable, this can be caused by a software failure, application conflict or overheating of the device. First of all, it is recommended to check if the flash is occupied by another process, for example, a camera application or a scanner. QR-code.
If the software methods don't work, try rebooting your smartphone, which clears your RAM and resets the temporary errors of the drivers controlling the hardware modules, and in rare cases, the problem may be physical damage to the plume or the diode itself, especially if the phone has recently fallen.
⚠️ Warning: If the flashlight does not work after falling or getting moisture, do not try to disassemble the device yourself - this may lead to loss of warranty.
Also worth checking for system updates. In newer versions of MIUI and HyperOS, developers often fix bugs related to managing peripherals. Go to Settings → About Phone → MIUI version and click the update check button.
