Flash when calling Xiaomi Poco: how to turn on and configure the notifications highlighting

Are you missing important calls because you can't hear the signal in noisy environments? camera flashlight on Xiaomi Poco could be your lifesaver! LED-flashing into a visual indicator of incoming calls, messages and notifications is the perfect solution for people with hearing impairments or those who are often in high-profile places.

Unlike the iPhone, where the flash is activated via Universal Access, on Xiaomi this setting is hidden deeper in the MIUI settings. Moreover, on different Poco models (from the budget Poco M to the flagship Poco F/Pro), the path to activation may differ. In this article, we will discuss all possible ways to enable the flash, from standard settings to hidden functions through the engineering menu.

Important: the feature only works when the screen is unlocked (in sleep mode, LED is not active) and can reduce battery life by 5-10% when used intensively. If you own a Poco X3/X4 Pro or newer models, check for Ambent Display – it can conflict with a flash.

Why the flash doesn’t work when calling Poco: common reasons

Before you set up the function, eliminate these typical problems:

• 🔋 Low battery charge (less than 15%) — MIUI switch off LED-energy-saving indicators.
• 📱 Active Do Not Disturb – Blocks all notifications, including lights.
• 🔧 Lack of feature in firmware – on some Poco C models and older versions MIUI (below 12.5) the option may be removed.
• 🛠️ Damage. LED-module – if the flash does not work in the chamber, repair is required.

If your Xiaomi Poco is under a global update MIUI 14, check the Special Options section, where a new Visual Notifications switch could appear. AMOLED-screens (e.g. Poco) F5 Pro) sometimes available alternative flashing screen instead of LED.

Method 1: Standard activation via MIUI settings

This is the most reliable method for most models, and the instructions are relevant for MIUI 12/13/14:

1. Open the Settings app (cog icon).
2. Go to the Special Features section (some firmwares call Universal Access).
3. Choose the Rumor. → Notification flash.
4. Activate the flash switch when you call.
5. Optionally: Enable Flash when notifications are available for messages.

On the Poco X5 Pro and new models, the path may be different:

Settings → Notifications → Additional settings → Flash notifications

- Battery charge >20 per cent

- LED-flashlight running in the chamber

- Do Not Disturb mode is off.

- The latest version has been installed MIUI-->

⚠️ Note: Some of the firmware for Poco M3/M4 If it's not on the menu, try resetting the Phone app through Settings. → Annexes → Application management → Phone. → Warehouse → Reset.

Method 2: Using a Hidden Engineering Menu (for Advanced)

If the standard method does not work, you can activate the function through the engineering menu, which is suitable for the Poco F1-F4 models and requires caution:

1. Open the Phone app.
2. Enter the combination: ##36446337## (code for the LED test).
3. In the menu that appears, select LED Testing.
4. Activate Flash Notification.
5. Save the settings and restart the device.

On Poco X3 NFC and later, this code may not work – instead, try ##4636## and go to the Equipment Testing tab.

Method 3: Third-Party Applications for LED Management

If you don’t have built-in features, use the apps from Google Play:

• 📱 Flash Notifications – Supports color, frequency and flash duration settings.
• 🔔 Flash Alerts 2 – works on Android 11+ It allows you to assign different colors to different contacts.
• 💡 LED Blinker – Compatible with Blinker MIUI 14 and supports screen blinking on AMOLED-model.

When installing, grant applications the rights to:

• Reading notifications (Notification access)
• The use of the camera (camera permission)
• Auto-start (Auto-start in MIUI settings)

⚠️ Attention: Management applications LED If you have problems with the camera after installation, clear the Camera app cache through Settings → Annexes.

💡

For models with IR-blaster (e.g. Poco) X3 Pro) you can use the infrared port as an additional indicator. IR Blaster Notifications and set up blinking IR-diode.

Frequency and color settings (for supported models)

On the Poco F5 Pro and some other models with RGB-LED, you can customize the backlight:

1. Install the Light Manager app (root or ADB required).
2. In the Notification LED section, select:

Incoming Call

Without root rights, the functionality is limited, but you can use it. ADB-base-setting:

adb shell settings put global notification_light_pulse 1


adb shell settings put global notification_light_color 0xFFFF0000

Where 0xFFFF0000 — It's the red color in HEX-For green, use the format. 0xFF00FF00.

💡

In the models with AMOLED-screens (e.g. Poco) F4 GT) A flashing display consumes significantly less energy than LED-We recommend using it as an alternative.

Solving problems: flash doesn't work after setting up

If LED doesn’t blink when calling, follow these steps:

1. Check the permits: 📋 Settings → Annexes → Permit management → Autostart – turn on the phone for the application. 🔔 Settings → Notifications → Additionally. → Priority Notifications – Add Your Phone to the List.

Reset the settings:

Settings → System → Resetting settings → Resetting all settings

This won’t delete your data, but it will return system parameters to factory settings.

Check the conflicts:

Disable ad blocking apps (like AdGuard) – they can block system notifications.

For Poco M5s and newer MIUI 14 models, you may need to disable battery optimization for system applications:

Settings → Battery → Battery Optimization → All apps → Find “Phone” and select “No Limits”

Alternative ways to visually notify Poco

If LED-Outbreak is not available, consider these options:

• 📱 Blinking screen (for AMOLED): activated through settings → Screen. → Blinking screen at notifications.
• 💡 Blind buttons: on some models (e.g. Poco) X3) You can set the flashing of touch buttons.
• 🔔 Backlit vibration: combination of tactile recoil and short-term screen turn on (tuned to Sounds and vibrations).
• 🌈 RGB-backlight: for Poco F5 Pro with Aura Light support - settings through Settings → Additionally. → Aura Light.

On the Poco C40 and other low-end models without LED, you can use a screen flash through the Screen Flash Notifications app. It briefly turns on the display to full brightness when an incoming call is made.
