Deep immersion in the device settings will help you maximize the potential of your gadget.
Activation through the control center and widgets
The most common and quickest way to access the flashlight feature on Xiaomi devices is to use a notification curtain, which requires unlocking the screen and swiping the control panel from top to bottom. Depending on the firmware version and regional settings, the icon may be called a flashlight or have a graphical designation in the form of a light bulb.
If you don't find the right icon on the first page, click on the edit button, usually located in the upper right corner or at the bottom of the list. In the menu of available widgets, find the flashlight element and drag it to the active zone. This action will fix the quick access button, allowing you to turn on the lights with one touch in the future without unnecessary movements.
In some cases, especially after a system update, the widget may disappear from the list of available or stop responding to clicks. In this situation, it is recommended to check for system updates or reset the control panel settings to factory values through the device's security menu, this often solves problems with incorrect display of interface elements.
⚠️ Warning: The LED module's long-term operation in flashlight mode heats the body in the camera area. Do not cover the phone with a cloth or leave it on unattended on soft surfaces to avoid overheating.
Using the Google Assistant voice assistant
Modern smartphones, including the Redmi 8, have powerful voice controls. Google's built-in assistant lets you activate a flashlight without having to unlock the screen or search for the right icons, which is especially convenient when your hands are busy or you're in complete darkness and you can't see the display.
To activate the function, you just need to say a key phrase, like, "OK, Google, turn on the flashlight." The system instantly recognizes the command and activates the LED. It's important to note that this function requires a stable Internet connection to work, since voice requests are processed on the company's servers.
You can also set up hand-free activation of the assistant. In the Google Assistant settings, enable the "Hey Google" option to let the phone respond to your voice greeting, which turns your smartphone into a full-fledged voice-controlled smart home device.
- 🗣️ Voice command: "Turn on flashlight" or "Turn on flashlight".
- 🌐 Requirement: Active connection to Wi-Fi or mobile data.
- ⚙️ Settings: Check the input language in Google settings for correct speech recognition.
💡
If the phone doesn't respond to voice commands in the dark, try first waking the screen with a short press of the power button, and then saying the command, which improves recognition accuracy in a quiet environment.
Activation setting by double pressing the power button
One of the most useful features of the MIUI shell is the ability to adjust actions when you double-press the power button. On the Redmi 8 model, this option is often used to start the camera, but it can be adapted for other purposes, including turning on the flashlight through third-party launchers or scripts, although the system natively offers the launch of the camera or Google Assistant.
To check the available settings, go to Settings → Additional Features → Buttons and gestures. Here you will find the option “Start the camera with double pressing.” While direct settings “Dual press flashlight” in stock firmware may not be available, using this feature to start the camera and then activate the flash is a common scenario.
For users who want to get a flashlight by double tap, there are specialized apps from the Google Play store that intercept this event. However, it is worth remembering that such applications can consume additional battery power in the background by tracking the state of the power button.
⚠️ Attention: Installing third-party button management applications requires special permissions (Accessibility) to use only proven high-ranking programs to avoid personal data leakage.
The alternative is to use automation scenarios if your version of MIUI supports advanced macros.You can create a scenario where a certain action (like shaking a phone) will include a flashlight, which may even be more convenient than double-pressing.
Flash mode in the Camera app
The primary purpose of the LED module on Redmi 8 is to illuminate objects when taking photos. The camera app provides the most convenient flash control. At the top of the shooting interface is a lightning icon that changes the modes of operation. LED-module.
There are three main modes of flash in the camera: Auto, On and Off. In Auto mode, the system analyzes the lighting of the scene and decides whether additional lighting is needed. On mode causes the LED to burn constantly during focusing and make a powerful flash at the time of the shot.
And the video mode deserves a special attention, and unlike a photo where the flash is short-lived, when you shoot video, the LED is in constant combustion mode, effectively turning the phone into a professional lighting fixture, which allows you to shoot quality videos even in complete darkness.
- ⚡ The smartphone itself decides when to use the light.
- 🔦 On: Flash burns constantly (lightlight mode in the camera).
- 🚫 Off: Forced shutdown, even if the room is dark.

Troubleshooting and Frequently Asked Questions
Despite the reliability of Redmi 8, users may experience a situation where the flashlight stops working, most often due to a software failure in the Android system or an application conflict. If the widget does not respond, try to restart the device - this solves 90% of problems with suspended services.
Another reason could be overheating. If the phone gets too hot, the protection system will automatically turn off the LED to prevent damage to the matrix or battery. Let the device cool down for 10-15 minutes and the function should work again. Also check if you have an application that has priority over the camera, such as messengers that could "grab" the module.
In rare cases, the problem may be hardware: If the LED does not light up even when an incoming call is made (if the notifications are set to suit), or the camera may have failed the module itself or the plume, in which case a diagnosis will be required at the service center.
