Light indicator on Xiaomi Poco M3: full setup of notifications and backlights

Xiaomi Poco M3 — pop-up AMOLED-It's a display and a minimalist design, but many users don't know how to make the most of its notification light. LED-Not only can it signal missed calls, it can also be part of your device's unique style. Unlike flagship models, where backlight is often integrated into the screen, the Poco has a unique design. M3 It is implemented classically - through a separate diode in the upper part of the body.

The problem is that the factory settings of the indicator are often limited to basic functions. Users are faced with the fact that the LED either does not work at all (due to the options disabled in MIUI), or flashes standard white without the possibility of customization. Meanwhile, with the help of hidden settings and third-party applications, you can adjust individual colors for each type of notification, change the blinking frequency and even synchronize the backlight with music. In this article, we will analyze all the ways, from official to advanced, including solving typical problems.

Where is the light indicator on the Poco M3 and how does it work?

On the Xiaomi Poco M3, the LED light is located in the upper right corner of the front panel, next to the front camera. It is a small round element that is illuminated when notifications are received. Unlike newer Xiaomi models (for example, the Poco F4 or Redmi Note 12), where the backlight is implemented through the screen (Always-on Display function), it uses a classic LED.

By default, the indicator supports the following states:

• 🔴 Red: Low battery charge (less than 15%) or missed call.
• 🟢 Green – Full battery charge.
• 🔵 Blue - new messages (SMS, messengers).
• ⚪ White – General Notifications (Mail, Social Media).

It is important to understand that the colors and behavior of the indicator depend on the version of MIUI. For example, in firmware based on Android 10 (MIUI 12), the list of supported colors is limited, while in MIUI 13/14 additional options appear.

⚠️ Warning: If the indicator does not flash at notifications, check if it is covered with a protective film or cover.

How to turn on the light indicator through standard MIUI settings

By default, the notification indicator is activated on the Poco M3, but its behavior can be adjusted.

1. Open Settings → Notifications and Status bar.
2. Go to the Notification Indicator (in some versions of MIUI it may be called Light Indicator).
3. Activate the switch Show notification indicator.
4. Select the apps you want to turn on the backlight (e.g. WhatsApp, Telegram, Calls).

In standard settings, the following parameters are available:

• 🔄 Color indicator - a choice of predefined options (red, green, blue, white).
• ⏱️ Blinking duration – short/long/permanent glow.
• 🔔 Types of notifications – calls, messages, system alerts.

The limitation of the standard menu is that you can't assign a unique color to each app, for example, you can't make WhatsApp flash green and Viber flash blue, and you need third-party solutions (which we'll talk about later).

Advanced configuration with Notification LED application

If standard settings are not enough, use Notification LED (available on Google Play) to:

• 🎨 Assign individual colors for each application.
• ⚡ Change the frequency of flashing (from slow to fast).
• 🔕 Turn off the lights at certain times (for example, at night).
• 🔄 Synchronize the indicator with music or alarm clock.

Instructions for setting:

1. Install Notification LED from Google Play.
2. Grant the application the rights to Notices and Special Features (required to read alerts).
3. In the main menu, select the app (such as Telegram) and set: Color of the backlight (you can choose from the palette or enter it). HEX-Blinking mode (Constant, Blinking, Pulse) Priority (if multiple notifications are sent at the same time).

Save the settings and test by sending yourself a test message.

⚠️ Attention: Some versions MIUI They block third-party apps with the indicator because of the energy saving policy. LED It doesn’t work, add it to your settings. → Battery → Optimizing the battery → All applications and disable optimization.

Adjust the indicator via ADB (for advanced users)

If you want to gain full control of the LED, you can use ADB commands. This method requires connecting the smartphone to the computer and basic knowledge of working with the terminal, but allows you to:

• 🔧 Change the brightness of the indicator (by default it is fixed).
• 🎯 Designate non-standard colors that are not available in MIUI.
• ⚡ Turn on the backlight even when the screen is off (bypassing the system limitations).

Step-by-step:

1. Turn on Developer Mode on Poco M3: Go to Settings → About Phone → MIUI Version. Click on MIUI Version 7 times until you become a developer!

USB debugging

Settings → Additional → For Developers

CMD

PowerShell

adb devices

If the device appears in the list, you can continue.

# Include red (values R, G, B 0 to 255)


adb shell"echo 255 0 0 > /sys/class/leds/red/brightness"




Blinking at 1 second interval



adb shell"echo 1000 > /sys/class/leds/red/delay_on"




adb shell"echo 1000 > /sys/class/leds/red/delay_off"

On the way to the indicator files instead of [color] substitute red, green or blue – it depends on the model of the LED in your Poco M3. Some devices may have only one RGB-diode controlled through /sys/class/leds/notification/rgb.

💡

Before experimenting with ADB, back up the data. Incorrect commands can cause the system to crash or turn off the indicator.

Frequent problems and their solutions

If the light indicator on the Poco M3 is not working or is not behaving correctly, check the following points:

• 🔋 Low battery power at a level below 5% MIUI Automatically switches off lighting to save energy.
• 📱 Update MIUI — After updating the system, the indicator settings may reset.
• 🛠️ Failure to work – restart your smartphone or reset your notification settings (Settings) → Annexes → Application management → ⋮ → Reset the settings).
• 🔒 Locking with a case - even transparent covers can scatter light. Try removing it and testing the indicator.

If the light flashes in the wrong color you set up:

1. Check if the settings of the standard MIUI menu conflict with third-party applications (e.g. Notification LED).
2. Turn off and turn on the Notification Indicator option again in the settings.
3. Update the apps responsible for notifications (such as WhatsApp or Viber) – sometimes bugs in their work affect the backlight.

How to turn off the light indicator completely

If you're annoyed by the backlighting (e.g., at night), you can deactivate it completely.

Method 1. Through MIUI settings:

1. Go to Settings → Notifications and Status bar → Notification indicator.
2. Turn off the switch Show notification indicator.
3. Save the changes.

Method 2. Through Notification LED (if previously used):

1. Open the app and go to the Global Settings section.
2. Activate the option to turn off the indicator.
3. Set a time when the backlight should be turned off (for example, from 23:00 to 7:00).

⚠️ Note: If you use Do Not Disturb Mode (Settings) → Sound and vibration → Do not disturb), the notification indicator will be turned off automatically, even if its settings are ticked.

Additional chips: synchronization with music and alarm clock

The light indicator on the Poco M3 can be used not only for notifications, but also for visual effects, for example, using the Music LED Control app (available on Google Play), you can:

• 🎵 Synchronize the flashing of the indicator with the rhythm of music.
• 🔄 Set up color transitions in the track time.
• ⏰ Use backlighting as an alarm clock (gradual brightness increase before waking up).

To set up:

1. Install Music LED Control and give access to the microphone (for audio analysis).
2. Select the source of the music (Spotify, YouTube Music, local files).
3. Adjust the sensitivity of the microphone and the color of the light.
4. Activate Synchronization with the music.

This is especially useful if you use the Poco M3 as a music station (e.g., connected to speakers via Bluetooth or AUX), and the backlight will add visuals and make listening more atmospheric.

💡

Synchronizing the indicator with music only works when the screen is on or the charger is connected. In the background, MIUI can block applications from accessing the LED.
