Owners of Xiaomi, Redmi and POCO smartphones often face the need to avoid missing an important call in noisy environments or when the device is lying down. Standard vibrations and melodies may not be enough, and here comes the help of light indication. Built-in LED indicator (if you have one in your model) or flash of the main camera can create a powerful visual signal that can not be ignored.
However, activation of this feature is not always obvious, since in the shell of MIUI or HyperOS settings can be hidden or called out-of-the-box. Many users mistakenly believe that this option is only available on older models, but modern Android smartphones successfully emulate the operation of the flash software methods. Let's see how to get your gadget to give light signals effectively.
In this guide, we will take a closer look at standard activation methods, customizations for different firmware versions, and alternative solutions through third-party software. You will learn how to manage the blinking frequency and understand why a feature may not work in the background without the right power saving configuration.
Activation through standard Android settings
The easiest and most reliable way to make a flash flash flash flash when you call in is to use the built-in capabilities of the Android operating system. In pure Android and most shells, this feature is hidden in the special features section. To find it, go to your device's Settings.
In the menu that opens, scroll down to Special Features (or Additional Settings) to find the section related to hearing or notifications. Depending on the version of MIUI, the path may be slightly different, but the logic remains the same: the system offers a visual replacement for audio signals.
Find the option "Flash for notifications" or "Flash on call" activate the switch next to this item. LED-It is important to understand that some models without a separate LED indicator will use a powerful camera flash.
- 🔍 Go to Settings. → Special facilities.
- 💡 Find the section "Hearings or Notifications.
- ✅ Activate the flash toggle for notifications.
- 📞 Check the work by making a test call.
It's worth noting that on some versions of the HyperOS shell, developers could change the location of this item. If you don't find it on the specified path, search by settings. Type the word "flash" or "notifications" into the search bar, and the system will suggest the desired switch.
Setup in the application Phone Xiaomi
The MIUI shell has its own set of features that can overlap with standard Android settings. Xiaomi’s built-in Phone app has its own call processing engine, so it’s logical to assume that display settings may be located directly inside the app.
Open the standard caller and click on the three dots or menu button in the top right corner. Select Settings. In the list that opens, look for Incoming calls. This is where the settings that control how the phone behaves during the call are hidden.
Inside the incoming call menu, find the flash when you call. Unlike the system setting, this option guarantees that it will work during the incoming connection, even if the system notifications are not working correctly. This is a priority rule for the Phone application.
⚠️ Warning: If you have enabled this feature but the flash does not light up, check if Do Not Disturb mode is activated. In this mode, visual notifications are often blocked by the system to ensure silence.
You can also set additional settings in this section, such as vibration or call volume, to create a comprehensive notification profile, and make sure the switch is active and lit in blue or green, indicating the function's state of operation.
☑️ Checking the call settings
Use of third-party applications
If the standard means to activate the blink failed, or the functionality of your Xiaomi model is limited, third-party applications from the Google Play Market will come to the rescue. They provide more flexible settings, allowing you to adjust the frequency of blinking, color (if iron allows) and signal duration.
One popular solution is the Flash Alerts app, or its analogues, and once installed, you'll need to give the program access to the camera and phone, so that the app can intercept the incoming call event and activate the flash at the right time.
The advantage of third-party software is that you can fine-tune it, you can set the delay before you turn on the flash, or you can make it blink only at certain times of the day, which is especially useful for saving battery life, which we'll talk about later.
| Annex | Type | Pluses | Cons |
|---|---|---|---|
| Flash Alerts | Universal. | Flexible setup | Advertising in the free version |
| LED Flashlight | Specialized | Minimum right. | Not enough settings. |
| Call Flash | For calls. | Working in the background. | Could be in conflict. |
| System Settings | Built-in | No installation required | Limited functionality |
When using third-party software, it is critical to configure permissions correctly, and without permission to work in the background, the MIUI system can kill the application process to save energy, and the flash will not work.
Problems with energy conservation MIUI
Aggressive battery optimization is one of the main features of Xiaomi smartphones, which aims to close all background processes to extend battery life, and unfortunately, useful features such as flash flashing when calling are often also under the knife.
To ensure that the flash is triggered, add the application you are using (whether it’s a standard Phone or a third-party program) to the exception list. To do this, go to Settings → Apps → All Apps.
Find the app you want and click on Battery or Energy Consumption, select No Limits mode, which will prevent the system from forcibly closing the app, allowing it to activate the camera or LED at any time.
💡
For maximum reliability, set up auto-start for the flash-controlling app, which will prevent it from turning off after the phone has restarted.
Also check the settings in the Security app, which is preset on all Xiaomi devices. In the "Permissions" section, make sure the app has the right to autorun. Without this right, after restarting the smartphone, the feature may stop working until you manually open the app again.
Features of work on different models
The implementation of the light display function depends heavily on the specific iron of your device. Flagship models of the past (for example, Mi 9, Mi 10) often featured a separate LED indicator under the screen that consumed minimal power.
Current low-end and mid-end models of the Redmi Note and POCO series often lack a separate diode, which uses a main camera flash to put additional stress on the battery and can heat the case with long series of missed calls.
Also, on AMOLED-type screens, which now dominate Xiaomi’s lineup, the “Always On Display” feature can conflict with the flash. If the screen is on to show the time, the flash may not be activated to avoid creating excessive light output.
⚠️ Attention: Frequently using a camera flash instead of an LED light speeds up wear on the camera matrix and drains the battery faster.
Users of models without OLED-screens (from IPS-The matrixes are more fortunate, they have fewer restrictions on the simultaneous use of the display and flash. However, the principle of operation remains the same: software emulation of flashing through the camera.
FAQ: Frequently Asked Questions
Why does the flash flash only flash once and stop?
Does this feature affect the battery’s discharge rate?
Can you set up a blink for specific contacts?
Will the flashlight stop working if this function is enabled?
Does it work in "Do Not Disturb" mode?
💡
The main secret of success is a comprehensive setup: turn on the function in the system, check the settings of the Phone application and be sure to add an exception to energy saving.
To sum up, flash activation on Xiaomi is a simple process, but requires attention to detail. The combination of system settings and the right power-saving configuration will allow you to never miss important calls, even in the noisiest places.
