Xiaomi Redmi 9C is a budget smartphone with a minimalist design, in which the manufacturer has saved on many “chips”, including hardware LED notifications. However, users often look for ways to return the usual indication of charge, messages or missed calls. In this article, we will discuss all possible methods of activating light alerts, from standard MIUI settings to bypass solutions using third-party applications.
It's important to understand that the Redmi 9C (M2006C3LG/M2006C3MI) is not physically equipped with a separate LED, like Xiaomi's flagship models. But that doesn't mean that the display is impossible to organize. Current versions of MIUI offer alternatives to screen notifications (screen blinking) and software emulation through a display or camera. We tested all the methods and collected working instructions with the latest updates in 2026.
Why is there no light indicator on the Redmi 9C?
The lack of hardware LED on the Redmi 9C is Xiaomi’s conscious solution to reduce the cost of the device. In the budget segment, manufacturers often sacrifice “secondary” features for the sake of price.
- 🔋 Battery savings: Hardware LED consumes energy even in standby mode, which is critical for smartphones with a 5000 mAh battery and a weak processor (Helio). G35).
- 📱 Trend to frameless screens: In models without “bangs” (like Redmi) 9C) It is difficult to place an LED without compromising the design.
- 🤖 Programming alternatives: MIUI It offers a replacement in the form of Ambient Display (screen notifications) and Always-on Display (on some models).
Interestingly, even in more expensive Xiaomi models (like the Redmi Note 10 Pro), the LED is often missing. The manufacturer is betting on screening — a short-term turn on the display when notified — this method is less noticeable, but more energy efficient.
Method 1: Enable notification screening (Ambient Display)
The simplest and most formal method is to activate the Ambient Display function, which briefly illuminates the screen when you receive notifications. It's not a full-fledged LED, but it visually performs the same role.
- Open the Settings → Screen.
- Select Ambient Display (in some versions of MIUI - Notifications Illumination).
- Activate the Display Notifications switch.
- In the Style section, select Colored for better visibility.
- Set the Blinking Frequency (we recommend it always or when you are notified).
Note: Ambient Display only works when the screen is off. If the smartphone is down or in your pocket, notifications will go unnoticed, and the feature may not work when power saving mode or if the application is locked in Battery Settings.

Method 2: Using the camera as an indicator (hidden MIUI function)
Little-known life hack: MIUI has a hidden option to use the camera flash for alerts. This method does not work on all firmware, but on Redmi 9C with MIUI 12.5+ it can be activated through special features settings:
- Go to Settings → Special Opportunities → Hearing.
- Select Notification Flash (or Light Alerts).
- Activate the function and adjust the flash color (white or color).
- In the Applications section, mark those for which indication is needed (calls, SMS, instant messengers).
The flash will only work when the screen is off and the smartphone is upwards, a method that is more visible than Ambient Display, but has limitations:
- ⚡ Quickly drains the battery (the flash consumes) ~0.5% charge in 10 blinks).
- 📵 Does not work in Do Not Disturb or with a silent profile.
- 🔦 May disturb at night (bright flash in a dark room).
💡
If the flash doesn’t flash, check permissions for the Special Opportunities app in Settings → Apps → Permissions management.
Method 3: Third-party applications for LED emulation
If standard methods don't work, you can install applications that emulate a light indicator through a screen or notifications. 9C:
| Annex | Functionality | Pluses | Cons |
|---|---|---|---|
| Always On Edge | Illuminating the edges of the screen at notifications | Low battery consumption, customizable colors | Does not work on a locked screen |
| Light Flow | Emulation of an LED through a screen or flash | Customization support for each application | Requires root rights for full functionality |
| Notification Light | Blinking the screen with a customizable frequency | Simple interface, no advertising | It can be a conflict with Ambient Display. |
For installation:
- Download the app from Google Play (e.g. Always On Edge).
- Grant permissions to Overlay over other Apps and Notices.
- Customize colors, blink duration and apps in the whitelist.
⚠️ Attention: LED emulation apps can increase battery consumption by 5-15% per day.Switch them off if you notice Redmi overheating or rapidly draining. 9C.
Method 4: Manually Incorporated through ADB (for Advanced)
If you're ready to experiment, you can activate hidden MIUI settings through ADB (Android Debug Bridge), a technique that requires a PC and basic command-line knowledge, but allows you to enable features that are not available in the interface.
Instructions:
- Activate Developer Mode on Redmi 9C (7 times click on the MIUI version in Settings → About Phone).
- Enable USB debugging in Settings → Additional → For developers.
- Connect your smartphone to your PC and open Command Prompt (Windows) or Terminal (macOS/Linux).
- Enter the command to check the connection: adb devices must appear serial number of the device.
- Execute the command to activate hidden indication: adb shell settings put global notification_light_pulse 1
After the reboot, the smartphone can start flashing the screen at notifications. However, this method does not work on all firmware and can cause MIUI to crash. If nothing changes after the command, return the default settings:
adb shell settings put global notification_light_pulse 0What to do if after ADB-commands the smartphone began to slow down?
Frequent problems and their solutions
Redmi 9C users often find that notifications don’t work even after setting up, and consider the typical reasons and ways to fix them:
- 🔕 Notifications blocked: Check permissions for applications in Settings → Annexes → Notification management: For example, WhatsApp or Telegram can be disabled from displaying alerts.
- 🔋 Energy saving mode: In Settings → Battery disable optimization for applications whose notifications are important.
- 📱 Smartphone lies screen down: Ambient Display and flash fail if proximity sensor picks up obstacle.
- 🔄 Firmware failure: After update MIUI You can reset the settings. Reactivate the Ambient Display.
If the display is unstable, try resetting the notification settings:
- Go to Settings → Applications → Notification management.
- Click on the three dots in the top right corner and select Reset Settings.
- Confirm the action and restart the smartphone.
⚠️ Attention: On some firmware MIUI 13+ Ambient Display may conflict with Always-on Display. If the screen does not go out completely, turn off Always-on in the screen settings.
Alternative means of warning
If light indication is important, but none of the methods are satisfied, consider alternatives:
- 🔔 Sound cues: Set up unique tunes for different apps in Settings → Sounds and vibrations.
- 📳 Vibration: Enable Vibration at Notifications and Configure Patterns in Settings → Special facilities → Vibration.
- 🌐 Smart devices: Connect Redmi 9C to Xiaomi Smart Home and set up the flashing of a smart lamp (e.g. Yeelight) at notifications.
- ⏰ Alarm Reminder: Apps like MacroDroid can trigger a timer or reminder when missed calls are made.
For owners of Xiaomi Mi Band or Smart Watch, there is another option: set up notifications on a wearable device, for example, the Mi Band 6 vibrates and illuminates when incoming calls or messages, which replaces the LED on the smartphone.
💡
If lighting is critical, consider buying a smartphone with a hardware LED (like the POCO X3 Pro or Redmi Note 11).
