Many owners of the popular Redmi Note 9 line of smartphones face the need for visual alerts for incoming calls, which is especially useful in noisy places when the phone’s sound is drowned out, or in the dark to avoid missing an important conversation. However, once you go into standard settings, users often find that there is no obvious “Flash on Call” switch in the call menu.
This is due to the features of the MIUI shell, which has its own specific location of parameters, in some versions of the firmware, this option is hidden in the depths of the system menus, and in others it requires the installation of an additional plugin or a third-party application for full operation. Understanding the architecture of the settings Xiaomi will help to quickly solve this problem without undue effort.
In this article, we will discuss in detail all possible ways to activate a flash when an incoming call. We will look at both standard methods available out of the box and solutions using third-party software if the standard capabilities of your region or software version are limited. Follow the instructions to ensure that your Xiaomi Redmi Note 9 always signals calls with light.
Finding a standard function in MIUI settings
The first step is to check if the feature is hidden in the standard interface of your operating system. In some regions (for example, India or the Global version), Xiaomi developers leave the ability to control the flash in basic parameters.
In the list that opens, look for Incoming Calls or Call Settings. If you're lucky, it might have a flash on notification or flashlight. However, on the Redmi Note 9 with MIUI 12 and later, this item is often missing by default due to energy saving policies or regional restrictions.
It's important to understand that not having a paragraph doesn't mean that the device is broken, it's a software limitation that you can bypass. → Settings → There's no incoming tumbler calls, so go to the following methods. Don't try to reset to the factory in the hope of finding this option, it's ineffective.
⚠️ Warning: If you don't find the switch in the standard menu, don't install questionable "patches" from unverified sources. use only official methods or proven apps from Google Play.
It's also worth noting that the feature can only work in a particular mode of the phone. For example, some users have noticed that the flash only activates when the screen is turned off or locked. Check the behavior of the device in different states before looking for complex solutions.
Activation through the menu of special features
There's a lesser-known way that's often overlooked, and there's a special feature section in the MIUI that's designed for people with hearing or vision impairments, and that's where the setting you're looking for might be hiding, which duplicates the sound signal with the light.
To access these options, go to the main smartphone settings menu, find the Advanced Settings section or the Special Features section. Depending on the MIUI version, the path may be slightly different, but the logic remains the same: we need features related to hearing or physical interaction.
Inside the menu, look for a "Hearing" or "Audiovisual Notifications" subsection, and you can have a "Ring Flash" or "Visual Alert" switch, and activating this setting causes the LED flash to flash when a call or message arrives.
- 🔦 Open the Settings. → Special facilities.
- 🔦 Select the “Hearing” or “Physical” tab».
- 🔦 Find the “Flash at Notifications” item and activate it.
- 🔦 Check the function by calling your number from another phone.
If this section is also empty or doesn't have the right options, then the manufacturer has blocked this feature at the firmware level for your model, and in this situation, third-party solutions come to the rescue, which we will discuss later, and you should not ignore this method, since it does not require the installation of additional software.
Why can’t the function function function function even after it’s turned on?
Use of third-party applications for calls
When Xiaomi’s regular funds do not give the desired result, the most effective solution is to install a specialized application. The Google Play store features many utilities that replace the standard call or complement its functionality, adding the ability to flash with a flash.
One of the most popular and reliable solutions is the Flash Alerts app, which is lightweight, doesn’t require complex resolutions, and works great on the Snapdragon processors installed in the Redmi Note 9. Once installed, you will need to give the program permission to use the camera and access calls.
In the application settings, you can flexibly adjust the flash behavior, you can choose to burn continuously during a call, flash periodically or flash once a call arrives, and you can often adjust the duration and intervals of blinking.
⚠️ Note: When installing a third-party call or plugin, make sure you only give the necessary permissions. SMS Untested applications with low rating.
Another important aspect is compatibility with MIUI. Some applications may conflict with the battery optimization system. To avoid problems, go to the battery settings after installing the program, find the installed application and select No Limits mode, which ensures that the system does not kill the blinking process in the background.
Set up notifications through system themes
Xiaomi’s unique feature is its powerful theme system, which, unlike other brands, allows you to change not only icons, but also system sounds, animations and interface behavior. Some themes already contain a built-in flash script when you call.
To use this method, open the standard Themes app, search for queries like Flash call, Light call, or Flash call, and you will be offered themes that modify the incoming call screen, and when you use this theme, the flash can be activated automatically.
However, this method has its drawbacks: Themes can be paid, advertised, or incorrectly displayed on the screen resolution of the Redmi Note 9. Also, after the system update or theme itself, the settings may get lost, which is less stable than using specialized applications.
However, for customizers, it's a great way to personalize your device. You can create your own theme or download a ready-made one that will not only include a flashlight, but also change the style of answering a call. Experiment with popular themes from the top charts labeled "Premium" or "Editor's Choice," which are usually better optimized.
| Activation method | Difficulty | Stability of work | Impact on the battery |
|---|---|---|---|
| Standard MIUI menu | Low. | Tall. | Minimum |
| Special facilities | Low. | Medium | Low. |
| Third-party annexes | Medium | Tall. | Average. |
| Systemic themes | Tall. | Low. | Depends on the topic. |
Solving energy conservation problems
A common reason why the flashlight doesn't light up even after setting it up properly is MIUI's aggressive energy saving policy.The system seeks to extend the Redmi Note 9's life and forcibly shuts down the background processes responsible for managing the flash.
To fix this, you need to manually prioritize the application that manages the flash (whether it’s a standard call or a third-party plugin). Go to Settings → Apps → All apps. Find the right app in the list and click on it.
From the app menu, select Energy Saving or Activity Control. Change the standard mode to No Limits. This is a critical step without which the function may not work smoothly. It is also recommended to stick the app in memory by swiping down the running task menu and pressing the lock.
☑️ Checklist of energy saving settings
Also, make sure you don't have Ultra-Energy Saving mode on or the hard light restrictions at night.These features can block the LED flash regardless of call settings. Check the Do Not Disturb mode schedule, as it can also affect visual notifications.
