Xiaomi’s Redmi series has long proven to be robust and feature-rich. One of the most sought-after features that can be needed at any time is a flashlight. Redmi 9 owners often look for quick ways to activate this option, especially at night. In this article, we’ll take a look at all the flash triggering methods available, from standard buttons to hidden system settings.
Understanding how to control the backlight on your device greatly improves the usability of the gadget in everyday life. We will consider not only basic algorithms of actions, but also advanced scenarios to make the flashlight more functional, and will also discuss issues related to possible failures in the module and how to fix them.
Quick activation through the notification curtain
The most obvious and quick way to light up is to use the control panel, which requires unlocking your Redmi 9 screen and swiping your finger from top to bottom. In the icon menu that opens, find a flashlight icon, which is usually located in the first or second row of quick settings.
If you don't see the icon right away, try swiping right or clicking on the edit button (often looks like a pencil or three dots). In the list of available widgets, find the flashlight and drag it to the active zone, and then access the function in one touch.
It's worth noting that some versions of the MIUI shell, if you press the flashlight icon long enough, open an additional menu, you can set a shutdown timer or select a blink mode, which is a useful feature if you use the phone as a signal beacon.
💡
If the flashlight icon is gray and not pressed, it may be that the function is occupied by another application, such as the camera. Close the background processes and try again.
The use of notification curtains is a standard method that works consistently on most devices, requiring no additional software installation and is available immediately after the phone is turned on.
Use of a combination of volume buttons
Xiaomi owners often wonder if it is possible to turn on the lights with buttons when the screen is off. In standard MIUI firmware, this feature is not activated by default, but it can be added through system settings or special applications. However, there is a caveat: on global versions of firmware, this option can be called “Switched-off flashlight”.
To check if you have this capability on your Redmi 9, go to Settings → Advanced Settings → Switched-off flashlight. If you have one, activate it. Then double-pressing the volume button (when the screen is off) will light the flash. This is extremely convenient when the phone is in your pocket or bag.
The system can limit the operating time in such a mode to prevent the LED from overheating. Do not keep the flashlight on through the buttons for too long unattended.
If this option is not available in standard settings, users often resort to third-party launchers or utilities from Google Play that emulate this feature, but native methods are always preferred in terms of energy efficiency.
Adding a flashlight widget to the desktop
For those who often require lighting, the best solution is to place the widget directly on the home screen, which allows you to start the flash without even unlocking the phone completely (depending on the security settings). On Redmi 9, the process of adding a widget is as follows:
- 📱 Make a long tap over an empty space on your desktop until the editing menu appears.
- 📂 Click on the "Widgets" button at the bottom of the screen.
- 🔦 In the list, find the "Tools" or "Lightlight" element and select the desired size.
- ✅ Drag the widget to the free screen space and release your finger.
Now you have permanent access to the feature. Some widgets allow you to change the color of the backlight if your phone supports it. RGB-notifications, although Redmi 9 uses a monochrome LED. widget can also display battery status, which is useful to know before long-term use.
Don’t overuse the number of widgets on the screen, as this can slow down the interface. Redmi 9 is equipped with a Helio G80 processor, which copes with tasks well, but the extra load on RAM is useless.
☑️ Optimizing the desktop
Placement of the widget is a matter of personal convenience. Some people find it easier to reach for the curtain, and some prefer to have a big button in front of their eyes. Choose the option that is right for you.
Voice control via Google Assistant
Modern smartphones, including the Xiaomi Redmi 9, have powerful voice controls, and if your hands are busy or your phone is far away, the easiest way to use Google Assistant is to say the activation phrase (usually "OK, Google" or "Hey Google") and the command "Switch on the flashlight."
To make sure that the method works correctly, make sure that the phone settings allow the assistant to access system functions. Sometimes after updating the MIUI, permissions may be reset. Check the Settings section → Apps → Google → Permits and make sure that access to the equipment is open.
Voice control is especially important in situations where visual contact with the screen is difficult, such as if you are holding tools or products, and the accuracy of the Russian command recognition in Google Assistant is quite high, which makes this method reliable.
⚠️ Attention: Voice assistant requires an Internet connection to handle some commands.
Also, keep in mind that the microphone must be clean and unobstructed, that in noisy environments, the phone may not recognize the command the first time, and that you should train diction and speak clearly for the best result.
Timer and operating mode settings
The built-in flashlight app in MIUI is often underrated, but it's a waste of time. It has more than just a constant light. When activated through a standard app (if it's displayed on the screen) or through some widgets, you can set up an automatic shutdown timer, which saves the battery if you forgot to turn off the lights.
And then there are strobe and SOS modes, which can be vital in emergencies, and to switch mode, you usually just have to tap the gear icon inside the flashlight interface or swipe through the active window.
The table below shows a comparison of the different flash modes on Redmi 9:
| Regime. | Description | Battery consumption |
|---|---|---|
| Permanent. | Continuous glow of maximum brightness | High-pitched |
| stroboscope | Frequent flashes with a given frequency | Medium. |
| SOS | Morse signal (three short, three long) | Low. |
| Timer. | Shutdown in 1, 5 or 10 minutes | Depends on the time. |
Using a timer is an effective way to save energy. If you use your phone as a nightlight, set a shutdown in 30-60 minutes, which will prolong the life of the battery and prevent deep discharge.

Auto-switch timer is the main function for saving battery power when using a flashlight as a temporary light source.
Don't ignore these settings as they help extend the device's autonomy in critical situations.The Redmi 9 has a 5020mAh battery, but LEDs consume power quite intensively.
Possible problems and solutions
Sometimes users are faced with a situation where the flashlight on Redmi 9 stops turning on or does not work correctly, most often due to a software failure or application conflict. If the button does not respond, the first thing you should do is try to restart the device, which solves 90% of the software problems.
If the reboot didn't help, check if the camera is being used by another app.The flash module is part of the camera and two apps can't use it at the same time.Close all background tasks through the menu of running apps.
In more complex cases, you may need to reset the Camera app settings or update drivers through the MIUI Update Center. Go to Settings → About Phone → System Update and check for new versions of the software.
⚠️ Warning: If the flashlight does not work even after rebooting and checking the settings, the plume or the LED itself may be damaged.

What to do if the flashlight flashes and goes out?
Detecting the problem in a timely manner avoids more serious breakdowns, and if you notice that the flashlight is dimmer than before, it may indicate LED degradation or power problems.
Effect of flashlight on battery
Many users worry about how frequent use of flash affects the battery condition of Redmi 9. LEDs consume significant current, especially in maximum brightness mode. Prolonged operation of the flashlight can quickly land the battery, especially if it is already worn out.
