Modern smartphones brand Xiaomi are equipped with many features designed to improve the user experience, but some of them can cause discomfort in everyday use. LED-A light that makes a camera flash flash when an incoming call or notification arrives, and it's useful in noisy places, but in the dark or in meetings, it becomes a serious hindrance.
Many users are faced with a situation where they can not find the switch in the standard settings menu, as the location of the options varies depending on the version of the MIUI shell or HyperOS. In some cases, the system can activate this feature on its own after a major software update, which the owner of the device often does not know.
In this guide, we will go into detail all possible ways to disable blinking, including standard methods and hidden settings of the engineering menu. We will look at the differences between different device models and operating system versions so that you can find a solution for your gadget. It is critical to distinguish between the system function “Flash on notification” and third-party applications-callers, as settings in them are managed independently from each other.
Standard settings of the MIUI and HyperOS interface
The first step in solving the problem should always be to check the basic settings of the system. Xiaomi developers often change the logic of the location of menu items, so even experienced users should double-check the current paths. Usually, LED control is in the section responsible for additional functions or special features.
You need to open the main settings menu of your smartphone and find a section that can be called "Additional Features" or "Advanced Settings." Depending on the regional firmware (Global, China, EEA), the names may vary slightly, but the meaning remains the same.
Inside this menu, you often find the option "Flash at Notifications" or "Blink at Call." If the slider is active, it needs to be put into an inactive state. On some models, such as the Redmi Note series, this switch can be hidden inside the "Special Features" submenu, which confuses many users.
💡
Before changing the settings, write down the current position of the sliders to quickly return everything as it was if necessary.
It's worth noting that the newer versions of the HyperOS shell have redesigned the indicator algorithm, so that the system can ignore the general settings if Do Not Disturb or Power Saving mode is activated, and check if these modes are enabled, as they can block manual control of the flash.
Configure through the application "Phone"
Often the problem lies not in the system settings of Android, but in the configuration of the application itself to make the call. Xiaomi’s standard “call” has its own set of parameters that prioritize the global settings of the system, and this is where the switch is most often hidden.
Open the Phone app and find a three-dot or gear icon, usually located at the top or bottom corner of the screen. In the drop-down menu, select Settings. Here is a list of all available options for managing incoming and outgoing calls.
Scroll down to the incoming calls or call settings section. This is where the flash incoming call switch should be located. If it's active, just turn it off. On some models, POCO this paragraph may be called «LED-indicator».
- 📱 Open the phone application (green handset).
- ⚙️ Click on the settings menu (three dots or gears).
- 🔍 Find the section "Incoming calls».
- ❌ Turn off the switchboard "Flash on call».
It is important to understand that if you use a third-party application for calls, for example, from Google or Truecaller, the settings of a standard Xiaomi call will not apply, in which case you need to look for similar options already inside the interface of the installed application.
☑️ Checking the call settings
Use of the CIT Engineering Menu
If standard methods didn’t help, it could be a deeper level of activation or a software failure. Xiaomi’s smartphones have a custom CIT (Customer Integration Test) menu to diagnose and manage hardware components, allowing you to test and customize individual modules of the device.
To enter the test menu, you need to open the Phone app and type a special code. Once you enter the last digit, the menu will open automatically. Be careful when working in this section, as changing unknown parameters can lead to unstable operation of the device.
##6484##In the list of tests, find the item associated with LED-It's an indicator or a flash. It can be called an indicator «LED You can click on it to check the module's performance. In some firmware versions, there is the ability to reset the module's settings or force it to disable its response to system events.
⚠️ Warning: Don't change the settings you're not sure about.The engineering menu is for diagnostics, and incorrect actions can lead to camera malfunctions or flashes.
Once checked, go back to the main menu and close the test. Often, the mere fact of logging in and out of the CIT menu unchanged reboots the LED control drivers, which can eliminate the software glitch that causes spontaneous blinking.
What if the code doesn't work?
Impact of Third-Party Apps and Themes
Often, the cause of obsessive blinking is user-installed design themes or call management apps. Themes from MIUI Themes store may contain their own scripts that activate the flash for visual effect, ignoring system settings.
Check which theme is currently active. If you’ve recently changed the design of your interface, try switching to a standard Classic or Default theme to see if the problem is with third-party software.
Also worth looking at are flashlight and notification apps, which often request permission to use the flash and can intercept the control of the flash module, and check the list of newly installed applications and their permissions under Protection or Security.
| Type of intervention | Probability of influence | Elimination method |
|---|---|---|
| A third-party topic | Tall. | Resetting the topic to standard |
| Call app | Medium | Setup within the application |
| Flashlight programmes | Low. | Removal or denial of access |
| System bug | Medium | Resetting or resetting settings |
Removing suspicious apps or returning to factory design often solves the problem instantly, and owners of Redmi and POCO devices are advised to be particularly careful about the themes downloaded from unofficial sources.
Problems after system update
An operating system update is always a lottery for custom settings. After installing a new version of MIUI or switching to HyperOS, some parameters can be reset to factory values. The flash flash flash feature is often activated by developers by default in new builds.
If the blinking appears immediately after the update, don’t panic. First, perform a full reboot of the device, which is necessary to ensure that all system services responsible for notifications and hardware, correctly initialized with the new parameters.
In rare cases, an update can damage the configuration file that stores your preferences. If a simple reboot doesn't help, you can try clearing the cache of the Phone app and the Settings system service.
To clear the cache, go to Settings → Apps → All apps. Find the Phone list, click Memory, and select Clear Cache. Repeat the same procedure for the Settings app. Then check flash status again.
⚠️ Warning: Don't confuse "Clear Cache" with "Clear Everything" or "Reset Data" buttons. The second action will delete your call history and reset your call settings to the factory.
Alternative Solutions and Hidden Commands
For advanced users who haven't found a solution in the standard interface, there are alternative methods that require more care, but allow you to get to the settings that are hidden from the average user, and one of these methods is the use of debugging commands.
Some Xiaomi models are responding to hidden USSD-codes or commands in engineering mode that allow behavior to be controlled LED-However, these codes may differ depending on the processor (Snapdragon or MediaTek) and the version of Android.
If nothing works, you can use third-party notification management tools that take precedence over system settings, and apps like NotifyBuddy or similar let you flexibly configure when and how a flash flash should flash, turning it off completely for calls.
- 🛠 Use apps to fine-tune notifications.
- 🔄 Try resetting the settings of special opportunities.
- 📲 Check apps access to camera and flash.
- 🔌 Disable fast commands in the Security app».
Remember that using third-party software to manage system functions always carries minimal risks. Before installing such programs, make sure that they are reliable and that you have positive feedback from other users of Xiaomi devices.
💡
The most effective way is to consistently check the settings in the Phone application and the system menu “Additional functions”.
