Many users who switch to smartphones of the line of Redmi, faced with the unexpected lack of the usual flashing LED on the upper edge of the case. In the model Redmi Note 9 engineers Xiaomi decided to abandon the classic LED. LED-This is often a puzzle for those who are used to seeing color alerts for missed calls or messages when the screen is off.
But don't worry, because the alert functionality hasn't gone away, it's just been moved to the software shell. The MIUI system that the device is based on offers alternative, and often more informative, ways to notify the user visually, and understanding how it works on your gadget will allow you to customize it as conveniently as possible for your own needs.
In this article, we will discuss in detail why there is no physical diode, how to activate its software counterpart and what settings you need to change to avoid missing important events. You will learn about the hidden features of the shell and ways to customize the interface that make using a smartphone even more comfortable.
⚠️ Note: Do not try to find an LED lamp around the speaker or front camera – it is physically absent in this model, so no software methods will not cause a non-existent element to burn.
Technical features of the display in Redmi Note 9
The Redmi Note 9 features a 6.53-inch IPS LCD display that occupies almost the entire front. In the pursuit of increasing the usable area of the screen, manufacturers are forced to remove physical buttons and sensors that were previously placed within the framework, which is why the classic LED indicator, which was placed over the screen or under the logo for years, was abolished in this model.
Instead of flashing a dot, Xiaomi has implemented Always On Display and the Flash Screen feature, which allow the screen to light up or change color when notifications arrive, not only replacing the good old diode, but also providing much more information: you can see not just the fact of the notification, but also its type, sender and time.
The rejection of the physical LED also has a positive effect on the power consumption and tightness of the case. Fewer holes and elements simplify assembly and make the device more reliable in operation. Although some users lack the usual blinking in the off state, modern OLED-screens (although the Note 9 is IPS, Blinking technology works similarly, allowing for more flexible backlight scenarios.
Activation of the "Switching Screen" function
The main replacement for the LED in the Redmi Note 9 is a feature that makes the screen briefly light up when an incoming call or message arrives. To activate this mode, you need to go to the system settings. Find the Settings section, then select the Lock Screen, and that's where the key parameters for visual signals in sleep mode are hidden.
Inside the menu, find the option Blink screen and move the switch to the active position. SMS Or the display will flash to attract attention, and it's the closest analogue of work. LED-It's important to note that for this function to work properly, the screen doesn't have to be completely off in deep sleep, but instead is in standby mode.
You can also adjust the duration and frequency of the flashing, if this option is available in your version of MIUI firmware. In some updates, the settings shells may be hidden in the Advanced Settings or Special Features section. If you do not find the switch right away, search by settings by typing in the "blink" or "indicator" request.

Setting up Always On Display for notifications
A more advanced way to visually control events is the Always On Display feature (AOD). Unlike a simple flash, this mode allows you to keep part of the screen constantly active, displaying the hours, date and icons of the received notifications. IPS-The matrix is implemented with some limitations compared to AMOLED-screens, but the basic functionality is present.
To enable, go to Settings → Lock screen → Always On Display and Lock screen. Here you can choose the display style and adjust the schedule. For example, you can set the function to turn on only from 8:00 to 23:00 so that the screen does not light up or interfere with sleep at night. This is especially true if you put your phone next to the bed.
It's important to understand that the constant glow of the screen consumes battery power. Although the Redmi Note 9 has a capacious 5020 mAh battery, active AOD can reduce battery life by 10-15%. So it's wiser to use Scheduled Mode or tap activation to balance convenience and energy efficiency.
⚠️ Note: Use the Always On Display mode on IPS-screens can cause uneven wear of backlights in the long run, so it is not recommended to keep it on 24 hours a day.
Lighting effects in the Camera app
Users often confuse the notification indicator with the camera flash, which can also be used as a light signal. Xiaomi has a feature that allows you to use the LED flash of the main camera module as an indicator of incoming calls. This can be useful in noisy places or when the phone is lying down the screen.
To enable this option, open the standard Phone app. Click on the three dots in the upper right corner or go to Settings inside the app. Find Incoming Calls and activate Flash when notified. Now when the flash rings, the flash will rhythmically light up.
This feature is independent of the state of the screen and works even if the phone is locked, but it is worth considering that frequent use of flash can heat the device body and land the battery faster.

Comparison of warning methods
Users often find it difficult to choose between different types of notifications, as each has its own advantages and disadvantages. To help you decide on the optimal setting for the Redmi Note 9, we have prepared a comparative table of basic methods.
| Method | Battery consumption | Visibility. | Informativeness |
|---|---|---|---|
| Blinking screen | Low. | Medium | Low (just the fact of the event) |
| Always On Display | Medium/High | Tall. | High (who and when) |
| Camera flash | Medium. | Very high. | Low (just the fact of the event) |
| Sound signal | Minimum | Depends on the environment. | Medium |
As you can see from the table, the most versatile solution is a combination of methods, for example, you can leave beeps for all applications, and for critical contacts (for example, from your boss or close relatives) you can set up a separate profile with a flash screen or flash, which will allow you to avoid missing a critical call, even if the phone is in your bag.
Also worth mentioning are third-party applications that emulate the LED light, programs like NotifyBuddy or Light Flow can make the screen flash different colors depending on the application, but they require constant CPU resources, which can negatively affect the autonomy of the Redmi Note 9.
💡
For maximum energy saving, set up a “Sleep” or “Night” profile, which automatically turns off all light and sound notifications from 23:00 to 07:00, leaving only the alarm clock active.
Solution: Why the Indicator is Not Working
There are situations where even after you turn on all the settings, notifications don't come or the screen doesn't light up, and most often the problem lies in the aggressive MIUI energy saving system, which kills background processes to save charge, and if the application you're waiting for the notification to come from is unloaded from memory, then the signal will not arrive.
To fix this, go to Settings → Battery and Performance. Find the right app in the list and select Unlimited mode. This will prevent the system from forcibly shutting down the program. Also check if Do Not Disturb mode is on, which blocks all visual and audio signals.
Another reason may be the outdated firmware version. Xiaomi regularly releases updates that fix screen and notification bugs. Check for updates along the Settings → About Phone → MIUI version. If a new version is available, it is recommended to install it by backing up the data beforehand.
⚠️ Note: When you reset to factory settings, all custom indicator configurations will be removed and will have to be manually configured again after the first boot of the system.
Additional personalization opportunities
MIUI is famous for its customization capabilities. In addition to standard settings, you can use a theme that changes the style of the lock screen and how notifications are displayed. Themes app has thousands of options, many of which have unique animations when messages arrive.
You should also pay attention to the Smart Lock Screen feature, which allows you to display weather, steps or news when the phone is in standby mode, which makes using the device more interactive and eliminates the need to constantly unlock the phone to check status.
Developer mode is available for advanced users, where you can find additional parameters for debugging the interface. However, these settings should be changed with caution, since incorrect values can lead to unstable system operation. LED-There is no indicator, since the hardware part in this model is not provided.
💡
The most reliable way to avoid missing the notification on the Redmi Note 9 is to use the sound signal, vibration and “Flash screen” settings in a comprehensive way, since there is no physical LED in the device.
