In todayβs smartphone world, where screens occupy almost the entire front panel, having a physical event indicator has become rare. However, for many users, LED notification indicator remains a critical feature to avoid missing an important call or message, even when the device is lying down or in your pocket. Xiaomi owners often wonder whether this option is still in their gadgets, as the companyβs policy in recent years has shifted towards Always-on Display.
Presence LED-The indicator depends not only on the model, but also on the year of release of the device. Flagship models of past years and budget smartphones of the middle segment often equipped with this element, while new premium devices are increasingly deprived of it to increase the display area. Understanding whether there is an event indicator in your model will help you to properly configure the alert system and avoid unnecessary battery consumption for constant switching on the screen.
In this article, we will discuss in detail which Redmi, POCO and Mi models have retained this useful element, how to activate it in hidden menus and what to do if the system does not allow blinking control by standard means. We will also look at software alternatives for devices where the physical diode has been eliminated by the manufacturer.
List of Xiaomi, Redmi and POCO models with indicator
You can tell if you have an LED by looking at the top of the screen when the display is off, usually a small hole next to a speaker or front camera. Xiaomi's lineup has a clear trend: the newer and more expensive the model, the more likely it is to have no physical indicator. The Redmi Note and POCO M budget series have long maintained this feature, making them popular with conservative users.
It is important to distinguish between the charge indicator and the notification indicator. The former can flash red or green when the charger is connected even when the charger is off, while the latter is activated only when incoming data arrives. Some models, such as the Redmi Note 8 Pro or Mi 9T Pro, use a multicolor LED that can display different colors for different applications, which greatly expands the functionality.
Below is a table with the most popular models equipped with this module. Please note that in global versions of MIUI or HyperOS firmware color management may be limited compared to the Chinese versions.
| Smartphone model | Type of indicator | Location. | Support for flowers |
|---|---|---|---|
| Smartphone model | Type of indicator | Location. | Support for flowers |
| Redmi Note 8 / 8 Pro | RGB LED | Over the screen | Multicolored |
| Xiaomi Mi 9T / 9T Pro | RGB LED | Hidden under glass | Multicolored |
| POCO X3 NFC | Single LED | In the cutout speaker | Unicolor (white/yellow) |
| Redmi Note 9 / 9S / 9 Pro | RGB LED | Over the screen | Multicolored |
| Xiaomi Mi A2 / A3 | RGB LED | Over the screen | Multicolored |

If you're not sure if you have an indicator, call your number from another phone in total darkness. If you have a diode, you'll see a characteristic blinking in the top of the case.
How to adjust the color and frequency of flashing in MIUI
Standard Android settings often do not provide enough control over the behavior of the LED. In the MIUI shell, the situation is similar: basic parameters can be hidden or limited. To get full access to the settings of the indicator, users often have to resort to third-party solutions or engineering menus. However, before installing applications, it is worth checking the basic features of the system.
Go to the Settings menu β Lock screen and password: This may be the "Notification Indicator" item, unless it's hidden by the developers for your particular model. ADB-commands that change the status of a function in the system. For advanced users, there is the possibility of using debugging on the system. USB.
βοΈ Setting up the indicator
β οΈ Attention: Using third-party LED control apps requires constant permissions to read notifications, which can reduce the privacy of your data.
If standard methods fail to configure the color scheme, you can use specialized utilities from Google Play, such as Light Manager or NotifyBuddy, which intercept system events and force the diode to activate the desired color.
Problems with the indicator in new versions of Android and HyperOS
With the release of Android 10 and subsequent versions, and the transition to HyperOS, Google has implemented strict restrictions on app access to the hardware notification indicator, which was done to unify the interface and promote the Always-on Display feature, which as a result, even on phones with a physical LED, it can stop blinking after updating the firmware.
Users often experience a situation where, after updating the system software, the indicator starts to work incorrectly, flashing only when charging or not at all, this is due to changes in drivers and power management policies. In new versions of the shell, priority is given to the software display of information on the locked screen, and the hardware is ignored by the default system.
Why did the indicator disappear after the update?
To solve this problem in HyperOS, it sometimes helps to completely reset the settings and then manually activate all the resolutions for the system application "Indicator" (if it is visible in the process list).However, on devices with Android 13 and above, the physical indicator is often completely software disabled at the kernel level, and it becomes impossible to return it without flashing it to the custom assembly (Custom ROM).
Software emulation of the indicator for models without LED
If your smartphone is from the line of Redmi Note 12, 13 or flagship Xiaomi 13/14 It doesn't have a physical diode, so you don't have to despair. AMOLED-The screens allow you to implement the Always-on Display function (AOD), It uses the minimum amount of energy, displaying only the necessary pixels, and it is an effective replacement, although it is inferior in visibility in bright sunlight.
To simulate the indicator, you can use applications that briefly turn on the screen or change the color of the pixels around the perimeter of the display when you receive a notification. Programs like Edge Light or Breathing Light create a ripple effect of the screen boundaries, which visually attracts attention, performing the same role as the flashing LED in older models.
- π΄ Edge Lighting β highlights the edges of the screen when notified, customizable color and duration.
- π’ Breathing Notifications β simulates a smooth fading glow similar to work LED.
- π΅ Always On AMOLED β Advanced configuring of the constantly on screen with minimal consumption.
The use of software emulation has its drawbacks, the main one being a higher battery consumption compared to a tiny LED that consumes a tiny amount of power. In addition, constant screen operation, even in minimal mode, theoretically can contribute to the risk of burning pixels (burn-in) on the screen. AMOLED-matrices with very long use of static elements.
Impact of the notification indicator on autonomy
One of the main arguments against LED-In fact, the current LED consumes so little power that its effect on the autonomy of a smartphone is almost imperceptible. During the day of active work with dozens of notifications, the diode can βeatβ less than 1% of the battery charge, which is incomparable with the power consumption of the screen or communication modules.
However, there are scenarios where the indicator can cause a discharge: if the controller application is "hanging" and keeps the diode on constantly, or if the system does not properly handle interruptions, the consumption current may increase, in which cases users notice heating of the upper part of the housing, where the LED module is usually located.

Physically LED-The indicator is much more economical than the constant switching on of the screen (AOD) or frequent display wakes to check notifications.
To maximize nighttime charge savings, it is recommended to use Do Not Disturb or sleep schedules, which not only block the sound, but can also turn off the light indication, avoiding the unnecessary blinking in the dark that can interfere with sleep, while still allowing you to skip a truly emergency call from selected contacts.
