Owners of Xiaomi, Redmi and Poco smartphones often face a situation where a standard vibration signal or melody is not enough to miss an incoming call or message in a noisy place. This problem is especially relevant for people with hearing impairments or for those who are used to keeping the phone in their pocket of jeans, where the vibration can go unnoticed.
In the current MIUI shells and the new HyperOS, the activation process of this option has undergone a number of changes, which often causes confusion among users who move from other brands or older versions of Android. The standard path through the special features menu is not always obvious, and in some cases the system can block the indicator from working due to energy savings. We will discuss in detail all possible ways to activate flashing flashlights for calls, SMS and applications.
Before you start setting up, it’s important to understand that this feature consumes additional battery power, albeit slightly. However, if you plan to use the light indicator all the time, be prepared for the fact that the battery life of the device may decrease slightly. Below is a step-by-step guide that will help you activate this useful option in a couple of minutes, regardless of the model of your smartphone.
Activation through the menu of special features
The most reliable and standard way to turn on flashing flashlights is to use the built-in settings section for people with disabilities. This is where the global switches that make you want to switch. LED-The camera module is operating in alarm mode. This method works on the vast majority of devices running Android and shells from Xiaomi.
First, you need to open the main settings menu for your gadget, scroll down to the Additional Settings section, and in some versions of the firmware, this item may be simply called "Advanced Settings." Inside this menu, find and select "Special Features," and that's where the key options for adapting the interface and device behavior are hidden.
After you go to the special features section, look at the top of the screen where the tabs are located. You need the Vision tab. When you click on it, you'll see a list of features that improve visual perception. Find Flash on alerts. Activate the switch next to it. The system can request permission confirmation — be sure to agree, otherwise the function will not work.
☑️ Checking flash activation
It's worth noting that depending on the version of MIUI, the location of the items may vary slightly. If you don't find the right switch right away, use the search bar at the top of the settings menu. Type "flash" or "flash" and the system will suggest the item itself, which is especially true for users who have upgraded to HyperOS, where the menu structure has been redesigned.
Blinking settings for calls and alarm clock
Once the main function is activated, the system often offers fine-tuning of exactly what situations the flashlight should be lit. By default, the light indication can only be turned on for incoming calls, but ignoring the alarm clock or messenger notifications would be counterintuitive. Let's see how to set these parameters in detail.
In the same menu where you turned on the main function, you usually have a "Settings" subsection or a gear next to the switch, and you can select specific scenarios here, and most commonly, options are "Switch on the flash for calls," "Switch on the alarm clock" and "Switch on the flash for the timer." Make sure that all the items you need are activated.
⚠️ Warning: Using an alarm clock can be critical for people who are sound asleep, but remember that if the phone is lying down on a soft surface (like a pillow), the LED can get hot. Do not cover the device with a cloth while the alarm clock with a flash is running.
In standard Android settings, if silent mode is enabled, the flash can also be blocked at notifications. To get around this limitation, you need to go to the Do Not Disturb mode settings and allow interruptions for contacts from your favorites, while maintaining the visual alert.
It is also important to note that some models with AMOLED-If you want the flashlight to flash, not the display, make sure that the screen settings have turned off the constant display of time, or select the appropriate lock style.
Using third-party applications for flexible customization
Xiaomi’s regular tools are good, but they don’t always allow you to set up blinking for specific apps like WhatsApp, Telegram or Viber. If the standard Flash Notification setting works only for calls, specialized utilities from Google Play come to the rescue. They provide enhanced control over LED-indicator.
One of the most popular and reliable solutions is the application Flash on Call, SMS & Alerts, which has a wide functionality and allows you to create profiles for different contacts, for example, for calls from mom, the flashlight can flash red, and from work – blue (if hardware is possible) or at different frequencies.
- 📱 Flash Alerts 2 – a powerful application with support for flashing screen and flashlight, as well as sound signals.
- 🔔 LED Flash for Alerts is a simple and easy solution that does not load the system and works in the background.
- 💡 Flash Notification – allows you to adjust the flashing color and speed for each application separately.
When installing such applications on Xiaomi, it is critical to configure the permissions correctly. MIUI is known for its aggressive work with background processes and often kills applications that are not in active use. In order for your notifier to work consistently, you need to fix the application in memory and allow auto-start.

Solving the Problem: Why the Flash Doesn't Work
Despite the ease of customization, users often find themselves in a situation where the function seems to be on, but the flashlight does not light up when you call, and this can be caused by several factors, from software conflicts to physical limitations. Let's look at the main causes and ways to address them.
The first and most common reason is energy saving mode: If the Xiaomi smartphone is powered by "charge saving" or "ultra saving", the system blocks the flash for notifications to save energy. Check the battery status and turn off hard saving modes if you need a visual indication.
The second reason is a conflict with other applications that use a camera or flashlight. QR-codes, a voice recorder with a recording function with light or a flashlight application, the system will not be able to use LED-Close all background tasks and try calling the number again.
The third reason is permissions. In the newer versions of Android (11, 12, 13, 14), flash access for notifications requires a separate permission, which must be given manually. Go to Settings → Apps → All Apps → Special features (or Accessibility) and check if there is permission to use the flashlight.
| Problem. | Probable cause | Decision-making |
|---|---|---|
| The flash doesn't blink when you ring. | Switch off in settings | Check the section "Special opportunities" |
| Only the screen flashes. | The "Screen Flash" option has been activated | Select "Camera Flash" in the settings |
| The function turns off itself. | Energy saving regime | Disable charge saving or add to exceptions |
| Does not work in specific applications | Lack of access rights | Give permissions in application settings |
💡
If you use a protective glass or a case with thick sides, they can block the flashlight or the proximity sensor. Remove the case and check the function — perhaps the problem is precisely the mechanical obstacle.
Features of work in HyperOS and new versions of MIUI
With the release of the HyperOS shell, which replaces MIUI, Xiaomi has made a number of changes to the logic of the system, this also affected notification management, the new shell has increased attention to privacy and energy efficiency, which sometimes leads to hiding the good old features in the depths of the menu.
In HyperOS, the path to flash settings can be aligned with global accessibility settings. Now the system more often suggests enabling Light Effects as part of a single visually impaired enhancement package. The interface has become more minimalistic, but less informative for advanced users accustomed to MIUI detail.
The important change was the separation of access rights, so that the flash-control application would not only have permission to access the camera, but also a separate permission to "Background Activity," without which the system demon responsible for blinking would be stopped within minutes of turning off the screen.
Also worth noting is the improved notification experience on the locked screen. In newer versions of firmware, the flash can sync with the animation of the notification appearing on the lock screen, creating a more aesthetic, but less noticeable effect in your pocket. If you want a powerful blink, look for the option “High Brightness Mode” or similar in the special features settings.
Effects on battery and LED life
Many users fear that frequent use of flash notifications can quickly disable the LED or significantly reduce the time of a smartphone from a single charge.
Modern. LED-The modules used in Xiaomi, Redmi and Poco smartphones are designed to last tens of thousands of hours. 1-2 The second incoming call has little or no effect on the LED's overall life, and the crystal's degradation is mainly due to overheating during long-term operation, which is not the case with notification mode.
In terms of power consumption, one flash pulse consumes a minimum amount of power. However, if you are in a poor area of the network and the phone is constantly catching the signal, and notifications are raining every minute, total battery consumption can increase by 3-5% per day.
⚠️ Warning: Prolonged flash operation in a confined space (for example, if the phone fell into a bag and was clamped with things) can lead to local overheating of the camera module. Although the system has overheating protection, try not to allow situations where the phone with an active flash is in a compressed state.
If you want to minimize the impact on the battery but leave a visual alert, consider using a Screen Flash instead of an LED. AMOLED-The screens light up only a small white pixel, which consumes much less energy than a powerful LED-lamp, though less noticeable in bright sunlight.
💡
Using the notification flash is safe for hardware smartphones, but requires monitoring the background activity of applications in new versions of MIUI and HyperOS.
