Owners of Xiaomi smartphones often face a situation where the usual notification indicator stops responding to incoming messages or works incorrectly. MIUI There is no possibility of detailed adjustment LED-It provides tools to control this functionality, although they are hidden deeper than on pure Android.
Understanding the principles of LED display is necessary for comfortable use of the device. LED-The indicator allows you to visually monitor battery status, missed calls and new messages without turning on the screen. In this article, we will discuss all available methods for adjusting color and flashing modes.
It is worth noting that the configuration options directly depend on the installed version of the firmware MIUI or HyperOS. In some cases, standard means to change the color will not work, and you will need to use third-party software.
Principles of LED-indication in MIUI
Xiaomi’s Android shell system uses a hardware LED to transmit status information. By default, the notification indicator lights up with a certain color depending on the type of event. For example, green usually signals a full charge or low battery level, and blue indicates a missed call or message.
It is important to understand that not all applications have management rights. LED-The system prioritizes system events and calls, and if you have installed the messenger, but it does not appear in the list of programs that use the indicator, then the hardware diode is closed by default.
⚠️ Note: On current Redmi and Xiaomi models, the LED can be software-operated to save energy or because of design features (using Always-On Display instead of the LED). LED). In such cases, the color adjustment program is not possible.
The indicator algorithm is written at the kernel level of the system. Changing standard color schemes requires tampering with system files or using special utilities that can intercept system calls.
Standard settings of the indicator through the menu
The first step that any Xiaomi user needs to take is to check the basic system settings, often solved by simply enabling a feature that was deactivated after the update. → Lock screen.
In the menu that opens, look for Notification Indicator, where you can find switches to enable the function as a whole. If the slider is active, the system allows applications to use LED, but the choice of a specific color is not usually provided here.
- 🔵 Blue: Most often denotes a missed call or message from social networks (Telegram, WhatsApp).
- 🟢 Green: Standard incoming signal SMS full battery.
- 🔴 Red: Critically low battery charge or missed important system call.
- 🟡 Yellow/Orange: notifications from third-party apps or low charge (depending on model).
Additional settings can be found in Settings → Advanced Settings → LED indicator (the path may differ on different versions of MIUI). Here, sometimes the option of flashing with a discharged battery is available. Make sure that all necessary switches are activated.
☑️ Checking the indication settings
Use of the Light Manager application
If standard settings aren't enough, the popular Light Manager app comes to the rescue, a powerful tool that allows you to customize the color of the indicator for each application separately, and is available on the Google Play Store and requires minimal access rights.
Once you install and run Light Manager, you need to give the application the permissions it needs, and it will request access to notifications and the system. LED-The controller will not be able to intercept signals from other programs and change the color of the glow.
In the application interface, you'll see a list of all the programs installed. Select the messenger or game you want. In the profile settings menu that opens, you can specify:
- 🎨 Color of glow: a choice from the full palette RGB, cliché.
- ⚡ Blinking mode: constant glow, slow or fast blinking.
- ⏱️ Duration: The time the indicator burns after receiving the notification.
- 🔇 Sound and vibration: the ability to synchronize a light signal with an audible signal.
⚠️ Note: Indicator management applications may consume additional battery power as they operate in the background, constantly polling the system for new events.
It is important to set priorities if you have multiple such utilities installed. Conflict of applications trying to manage the same hardware resource can lead to chaotic blinking or complete failure of the function.
Why are the settings resetting?
Configure with ADB and system commands
For advanced users who want to change the color of the indicator without installing third-party software, there is a method using debugging over USB and the ADB command line.
First, activate Developer Mode. Go to Settings → About Phone and click on MIUI seven times. Then, in Advanced Settings → For Developers, turn on USB Debugging.
Connect your smartphone to your computer and execute a command to check the connection. If the device is identified, you can change the parameters via shell commands, although there is no direct command to change the color of the LED in the standard ADB, often changing the values in the settings database:
adb shell settings put secure notification_light_pulse 1This command forces the pulse of the indicator, but to change the color (RGB values) often requires root access or specific modifications of the system, because these parameters are rigidly set by the vendor in the drivers.
| Parameter | Value 0 | Value 1 | Description |
|---|---|---|---|
| notification_light_pulse | Off | On | Global Blinking Included |
| led_brightness | Low. | Tall. | Brightness of the LED (depends on the model) |
| breath_light_color | Standard | Custom | Color selection mode (rarely available) |
| charging_light | Off | On | Indication of the charging process |
Using ADB requires caution. Changing system keys incorrectly can lead to unstable interfaces. Always back up the data before experimenting.
Solving problems with a broken indicator
There are times when the notification indicator stops lighting up completely, even after setting it up correctly. The first reason may be the Do Not Disturb function or the set sleep mode. Check the schedule of these modes in the Zen mode settings.
The second common problem is aggressive energy saving. The system can turn off LED power for background applications. Go to Settings → Battery → Application Energy Saving and find the problem program. Set No Limits mode.
- 🔄 Reboot: A banal but effective way to reset driver errors LED.
- 📱 Approximation sensor check: sometimes sensor contamination blocks screen and indicator switching on.
- 🛠️ Resetting: a last resort if a software failure blocks hardware.
It's also worth checking if Pocket Mode is enabled, and if the system thinks the phone is in your pocket, it blocks all light and sound notifications to keep the battery from running out of steam.
💡
If the indicator flashes red when you connect the charger, but the phone is not charging - this may indicate a deep battery discharge. 30-60 minutes.
Alternatives: Always-On Display and Screen Notifications
With the development of technology OLED-Smartphone manufacturers including Xiaomi have begun to abandon physical LEDs in favor of the Always-On Display feature (AOD). This is an energy-saving mode in which a portion of the pixels remains active, displaying the time and icons of notifications.
You can set up AOD through the Settings menu → Lock screen → Always-On Display. Here you can choose the display style, color and schedule. This is a more informative replacement for the blinking diode, since it shows not only the fact of the notification, but also its source.
The advantages of AOD over LED are obvious:
- 🖼️ Informative: you can see who wrote it, not just blinking.
- 🎨 Customization: You can choose any color and font.
- 🔋 Savings: modern matrices consume a minimum of energy on a black background.
⚠️ Note: Always-On Display is available only on smartphones AMOLED/OLED On devices with screens. IPS-matrix (LCD) This function is technically impossible, as it requires full screen lighting.
If your budget Redmi does not have LED-indicator AMOLED-The only option is audio notifications or widgets on the desktop. LED-Cases that are put on the phone and have their own programmable indicator.
💡
The rejection of physical LED in favor of software display on the screen (AOD) is the main trend of the modern smartphone industry, providing greater flexibility in settings.
