How to turn off the indicator light on Android when there is an incoming call on Redmi

Modern Xiaomi and Redmi smartphones running on the MIUI shell or the new HyperOS are equipped with many functions designed to improve the user experience. However, sometimes these functions become intrusive, especially at night. One of these features is the LED notification light, which starts flashing brightly when there is an incoming call.

For many users, this is a serious problem that disrupts sleep and irritates the nervous system. Manufacturers often hide the settings for this element deep in the menu or completely remove the ability to disable it in the standard settings. In this article, we will analyze in detail all the available ways to deactivate the light alarm on Redmi devices.

You will learn how to find hidden engineering menus, what applications can help solve the problem, and why standard settings sometimes do not work. We will look at the nuances for different versions of the Android operating system, since the logic of the system changes with each major update.

Searching for standard settings in the MIUI interface

First of all, you need to check the basic system settings. In earlier versions of the MIUI shell, control of the light indicator was placed in a separate menu item. However, with the release of Android 10, 11 and higher, Xiaomi developers decided to simplify the interface, removing many of the settings “for advanced users.”

However, in some firmware the path to configuration still exists. You should go to section Settings → Notifications and status bar. Here, carefully review the list of available options. If you see the item Indicator light or LED indicator, simply move the switch to the inactive position.

It’s also worth checking the settings of the “Phone” application itself. Sometimes flashing control is tied specifically to the bell function, and not to the system as a whole. Go to Settings → Applications → Manage applications → Phone and look at the notifications section.

It is important to understand that the absence of a switch in this menu does not mean the phone is broken. This is a conscious decision by the developers and can be circumvented using other methods described below. Do not rush to reset the settings to factory settings, this rarely helps in this case.

Using the CIT engineering menu to disable

If the standard interface does not provide the necessary options, the CIT (Customer Integration Test) service menu comes to the rescue. This tool is designed to diagnose hardware, but also allows you to control some hardware functions, including the LED.

To enter the menu, enter a special code on the phone keypad ##6484##. After entering the last star, the menu will open automatically. The interface is a list of tests, each of which is responsible for a specific module of the smartphone.

In the list you need to find an item related to LED or Light. Names may differ depending on the model Redmi Note or Redmi K. Often this is item LED Test or Notification Light. By clicking on it, you can check the functionality of the diode and, in some software versions, disable it.

⚠️ Attention: Be extremely careful in the engineering menu. Changing unknown parameters may lead to incorrect operation of the sensor, battery calibration, or failures in the communication module. Change only those settings that affect the light indicator.

It is worth noting that in the latest HyperOS updates, access to some tests through this code may be limited or require entering an additional password. If the code does not work, try the alternative ##4636##although it is more often used to configure the network.

Using third-party applications to control LED

When system methods are exhausted, applications from the Google Play Market come onto the scene. There are a number of utilities that intercept control of the LED and allow you to flexibly configure its behavior, including completely turning it off during calls.

One ​​of the popular solutions is an application Light Manager or analogues like NotifyBuddy. These apps require special permissions, such as access to notifications and control over other windows. After installation, you can create a profile in which the LED action will be set to “Off” for the “Incoming Call” event.

The advantage of this approach is flexibility. You can set the light to flash only for missed calls or messages from certain contacts, ignoring regular calls.

• 🔹 Light Flow: A powerful tool with support for thousands of applications and complex operating scenarios.
• 🔹 LED Blinker Notifications: A simple and lightweight application that allows you to quickly turn off the light for specific events.
• 🔹 NotifyBuddy: Uses a screen instead of an LED, but also has control hardware LED on older models.

However, using third-party software has its drawbacks. Such applications run in the background, which may slightly increase battery consumption. In addition, MIUI's aggressive power saving policy can "kill" the application process, resetting your settings.

Hidden features via ADB and computer

For advanced users who are not afraid to work with the command line, there is a method to disable the indicator via USB debugging. This method requires connecting your smartphone to your computer and installing ADB drivers.

First you need to activate developer mode. Go to Settings → About phone and quickly click on the item MIUI version seven times in a row. After the message “You have become a developer” appears, go to Additional settings → For developers and enable Debugging USB.

Connect your phone to your PC, open the ADB console and enter the command to get a list of packages responsible for notifications. Often a system package com.miui.aod or notification services is responsible for the LED.

adb shell pm list packages | grep notification

Once you find the package you need, you can try to disable it or change the settings through commands pm disable, but this is a risky method that can disrupt the operation of the entire notification system. A safer option is to use utilities like ADB AppControl, which has a graphical interface and allows you to safely freeze the system components responsible for the LED.

Features of working in the "Not" mode disturb"

Often users do not want to turn off the lights always, but only at certain times, for example, at night. The built-in mode Do not disturbis ideal for this. Unlike completely turning off the indicator, this mode allows you to flexibly customize the behavior of the phone at specified hours.

You can activate it through the notification curtain or in settings Sound and vibration → Do not disturb. In the parameters of this mode, find the section Behavior for incoming calls. Here you can prevent the screen from turning on and, importantly, the indicator blinking.

Setting a schedule will allow the phone to automatically switch to quiet mode, for example, from 23:00 to 07:00. During this time, the LED will not respond to calls, but the phone will continue to receive calls (unless you set a full lock).

⚠️ Attention: In some versions of MIUI, the Do Not Disturb mode turns off only sound and vibration, but leaves the indicator light active. Test this setting experimentally before going to bed.

There is also a function Scheduling on/off in the main phone settings. It allows you to completely turn off the device at night, which is guaranteed to get rid of any light, but you will miss emergency calls.

Hardware solutions and physical limitations

It is worth mentioning that modern Redmi smartphones are gradually being phased out full multi-color LED indicator. In budget models and many new products in the middle segment, its place is taken by a notification screen Always-on Display or simply blinking of the main screen.

If you have a model where the screen plays the role of an indicator, you can turn off the “light” only through the settings Always on screen or by prohibiting the display from turning on for notifications in the lock settings. It is impossible to physically seal the LED in such models, since it is not there.

In older models, where the LED is located under the glass of the front panel, the most radical but effective method is physical blocking. You can use opaque tape or a special sticker. This requires no software intervention and works 100%.

However, if you plan to sell the phone, traces of glue may reduce its value. Therefore, software methods are preferable. If none of the methods helped, perhaps the problem lies in a specific bug in your firmware version.
