In this article, we will discuss all possible ways to customize visual alerts – from standard tools to hidden chips through the Internet. ADB You will learn how to make a flash flash flash when calling, why the LED does not work on some models (for example, the Redmi Note 10 Pro), and how to circumvent the restrictions. MIUI 14 without root permissions, and also a feature compatibility table by model and answers to frequent questions.

1. Standard settings MIUI: light-emitting diode

So let's start with the simplest one, built-in options. MIUI The 12-14 path to notification settings may vary depending on the firmware version, but the general logic holds. Importantly, not all Xiaomi models support flash when alerts are at the system level. 9A and POCO M3 This function is not available due to hardware limitations.

To check the available options:

  1. Open Settings β†’ Notifications and Status bar.
  2. Select Application Notifications.
  3. Tapping on the desired app (such as WhatsApp or Calls).
  4. Find the Light indicator or flash at notifications.

If there's no flash, your model doesn't support it at the software level, but don't despair, we'll look at workarounds below, and if there is, you can choose:

  • πŸ”¦ Blinking color (blue, green, red – depends on the model).
  • ⚑ Frequency of outbreaks (slow, fast, constant).
  • πŸ”” Notification types (calls, SMS, messengers).

If the settings do not include the item "Light indicator", try to update MIUI until the last version. MIUI 13.5+ Flash support for some budget models that previously did not have it.

In the models with AMOLED-screens (e.g. Xiaomi) 12T or Redmi K50) Instead of LED, you can use the backlight of the screen - the so-called "Always-On Display" (AOD). To activate it:

The outbreak is triggered with a delayBattery Optimization Limits Background ProcessesAdd the app to exceptions (Settings β†’ Battery β†’ Battery Optimization)
The function disappeared after the updateXiaomi has removed support in the new version MIUIRecoil on previous firmware or use ADB

Critical Feature: Starting with MIUI 14, Xiaomi has begun gradually removing flash support when notifying on budget models (e.g., Redmi). 10A or POCO C40). This is due to optimizing power consumption, and if your smartphone is released after 2022, it’s likely that the feature is locked at the software level.

πŸ“Š Your Xiaomi smartphone supports flash when notified?
Yeah, it works out of the box.
Yeah, but I had to manually adjust.
No, but the model is not budgetary.
No, and I don't know why.
I have a different brand.

Another common problem is the power saving problem, where if the battery is under 15 percent, the system automatically turns off all visuals, including flash, to avoid this:

5. Alternative methods: screen blinking and vibration

If neither flash nor LED is available, other visual and tactile alerts can be used:

Screen flashing (Screen Flash)

Some Xiaomi models (e.g. Mi 11 or Redmi) K40) They support the flashing of the screen when you're notifying:

6.A Guide to Specific Xiaomi Models

Not all Xiaomi smartphones are equally supportive of flash notifications, here is a brief guide to popular models:

ModelSupport for the outbreakSupport for LEDRecommendations
Redmi Note 10 Pro❌ No. MIUI 13+)❌ No.Use Flash Notifications or AOD
POCO X3 Proβœ… Yes. ADB)❌ No.Activate through ADB third-party
Mi 11 Liteβœ… Yes.❌ No (AMOLED)Set up in Notifications β†’ Flash or use it. AOD

Xiaomi 12βœ… Yes.❌ No (AMOLED)Configure in standard settings or through AOD

For models POCO (for example, POCO F3 or POCO X4 Pro) often requires unlocking the bootloader to fully work the flash, due to Xiaomi's policy of limiting functionality in "global" firmware:

  1. Unlock the bootloader through the official Xiaomi tool.
  2. Install custom recovery (such as TWRP).
  3. Sweep through the Xposed or Magisk module with a flash patch.

πŸ’‘

Unlocking the bootloader resets all the data on the smartphone! Backup is mandatory. Also note that this can take away the warranty.

7 Energy consumption and how to reduce it

The constant flashing or backlighting of the screen increases battery consumption. According to our tests, on the Redmi Note 11 with an active flash for WhatsApp and Telegram, consumption increases by 8-12% in 8 hours.

  • πŸ”‹ Turn off the flash for low-value apps (such as games or newsfeeds).
  • ⏱️ Set a time limit (for example, blinking only from 20:00 to 8:00).
  • πŸŒ™ Use the Dark Theme -- on AMOLED-screens, it reduces the load.
  • ⚑ Turn off Constant Screen Activity in Notification Settings.

If the battery is running out too quickly, check which apps are using the most power:

  1. Open Settings β†’ Battery β†’ Battery Use.
  2. Find apps with a flash in the top of the flow.
  3. Limit their activity in the background or turn off the blinking.

πŸ’‘

On smartphones with Snapdragon 8xx (For example, Xiaomi 12 Pro, the flash power consumption is lower than on budget chips.

It is also worth considering that MIUI It aggressively optimizes the background. If the flash stops working after a few hours, add the app to the exceptions:

  1. Go to Settings β†’ Battery β†’ Battery Optimization.
  2. Find a notification app (such as Flash Notifications).
  3. Choose No Limits.

8. Frequent mistakes and how to avoid them

When setting up a flash when notifying users, they often encounter typical problems. Here's how to solve them:

Mistake 1: The flash only works once.

Reason: In the application settings, flashing is set 1 time. Solution:

  1. Open the Flash Notifications (or analogue) settings.
  2. Select Repeat Flash (Repeat Flash).
  3. Set the interval (e.g. every 3 seconds).

Mistake 2: LED lights constantly, not blinking

Reason: Conflict with other system notifications.

  • Turn off the Light indicator for unnecessary applications in the settings MIUI.
  • Reboot your smartphone.

Error 3: The flash does not work in Do Not Disturb mode

Reason: MIUI It blocks all alerts, including visual alerts:

  1. Open Settings β†’ Sound and vibration β†’ Do not disturb.
  2. Add an exception for the desired applications.
  3. Or shut down the mode completely.

If it didn't work, try rolling back to the previous version. MIUI via Fastboot (instructions on the forum Xiaomi.eu).

Mistake 4: The outbreak is triggered by a delay

Reason: Battery optimization or slow processor. Solution:

  • Add the notification app to Battery Exclusions.
  • Turn off the energy saving for the processor in the developer settings.
  • Use lightweight apps (e.g. Flash Alerts 2 instead of Light Flow).

πŸ’‘

If none of these things work, check the hardware health of the flash. Open the camera and turn on the flashlight -- if the LED doesn't burn, the camera module is the problem.

FAQ: Answers to Frequent Questions

Can you customize different flash colors for different applications?

The flash is working, but the battery goes down very quickly. What do we do?
Blinking a flash or backlight does increase battery consumption. To reduce consumption: Reduce the blinking frequency (e.g., 1 time every 5 seconds instead of a constant one). Turn off the flash for low-value notifications (social media, games). Use Dark Theme and turn off Always-On Display during the daytime. Check if notifications are duplicated (for example, if you have two messengers installed for one account). MIUI Go to Settings. β†’ Battery β†’ Battery usage and see how much power Flash Notifications or its analogue spends.
Can you make the flash flash only at night?
Yes, you can configure this in two ways: Through third-party apps: Flash Notifications or Light Flow has a Schedule option. Set an interval, for example, from 22:00 to 7:00.
