How to set up flash flash flash when calling Xiaomi: all ways

Incoming lighting is a useful feature for those who often miss a call in noisy environments or when the sound is turned off. On Xiaomi smartphones, you can implement flash flash flashing in several ways: through standard MIUI settings, using third-party applications or even through hidden engineering menus. In this article, we will analyze all the current methods for different versions of firmware and models, from budget Redmi to flagship Xiaomi 13/14.

It's important to understand that not all devices support this out of the box feature. For example, on some Poco models, the option may not be on the menu, and on older versions of MIUI 11 and below it was not at all. We'll look at workarounds for such cases, including installing specialized utilities and changing system parameters, you will learn how to adjust the blink color, flash frequency, and even synchronize the LED with the ringtone.

══════════════════════════════════════════════════════════════════════════

1. Standard setting via MIUI menu (for supported models)

On most modern Xiaomi smartphones with MIUI 12-14 firmware, the flash flash option is built into the system settings.

1. Open the Settings app (the gear icon on the home screen).
2. Go to the section Sound and vibration.
3. Select Incoming Calls.
4. Activate flash flash slider (or Light display on some models).

If this item is not available, then your model does not support the function at the software level, in which case move on to the next section with alternative methods.

Check the version of MIUI in Settings → About the phone

Make sure the flash is running in flashlight mode.

Update the firmware to the latest version

Try restarting your phone if the option doesn't show-->

On some devices (for example, Xiaomi 11T Pro or Redmi Note 12 Pro+) additional options are available:

• 🔄 Blinking frequency: slow/fast/synchronized with ringtone
• 🎨 Flash color: white/warm/cold (on models with RGB-flash)
• 🔔 Exceptions: you can turn off blinking for specific contacts

⚠️ Attention: On devices with AMOLED-With screens (e.g. Xiaomi 13 Ultra) a long flash can cause the matrix to overheat at high brightness.

2. Alternative method: application "Flash Alerts 2"

If there are no standard settings, the most reliable solution is to install a third-party application. Flash Alerts 2 (from NoxLabs developer) works on all Xiaomi models, including those where the function is disabled by the manufacturer. The application is free, but contains advertising (it can be disabled through the purchase of the Pro version).

Download the utility from Google Play and follow the instructions:

1. After installation, open the application and provide all the permissions requested (access to notifications, camera, phone).
2. In the main menu, activate the Flash on Call switch.
3. In the Customize section, set up: 🔦 Brightness (recommended 70-80% for battery savings) ⚡ Blinking mode: constant/intermittent/synchronized with melody 📱 Exceptions: You can turn off for specific contacts or applications

Persistent Notification

The advantage of this method is the flexibility of settings, for example, you can adjust different colors of blinking for calls, SMS And notifications from messengers. It also supports the work with LED-Indicator (if you have it on your model).

💡

If the flash doesn’t flash after installing Flash Alerts 2, check if the battery optimization is blocking it. Go to Settings → Applications → Application Management → Flash Alerts 2 → Battery and select Unlimited.

3. Customization through the engineering menu (for advanced users)

On some Xiaomi models (e.g. Redmi 9 or Poco X3), the flash flash blink option is hidden in the engineering menu, a method that requires caution since incorrect changes can lead to system failures, and is recommended only for power users.

Instructions:

1. Open the Phone app and enter the combination: ##36446337## (code may vary for different models).
2. From the engineering menu, select Hardware Testing → Audio → Flashlight.
3. Find the Flash on Call option and set the Enabled value.
4. Save the settings and restart the device.

⚠️ Warning: Changes to the engineering menu can reset network settings or cause errors in the camera. Before experimenting, back up your data via Settings → Additionally. → Backup and reset.

Flashing through ADB (no root)

If standard methods don’t work, you can activate the feature via Android Debug Bridge (ADB), which doesn’t require superuser rights, but you need basic command line skills.

Step-by-step:

1. Download and install ADB Tools on your computer.
2. On the phone, activate Developer Mode (7 times click on the Build Number in Settings → About Phone).
3. Enable USB debugging in the developer menu.
4. Connect your phone to your PC and type in the command line: adb shell settings put global flash_notification_enabled 1
5. To check, enter: adb shell settings get global flash_notification_enabled (return 1).
6. Reset the device.

If the team doesn’t work, try an alternative:

adb shell content insert --uri content://settings/system --bind name:s:flash_notification_enabled --bind value:i:1

This method works on most MIUI 12+ devices, but may not be supported on custom firmware or heavily stripped-down models (e.g. Redmi Go).

5. Problems and Solutions: Why Flash Blinking Doesn't Work

Even after setting it up properly, the function may not work. Consider the reasons and ways to fix them:

If none of the methods worked, check:

• 🔋 Battery charge: on some models, the blinking is turned off at a charge level below 15%.
• 📱 System Updates: In Older Versions MIUI (below 12) the function may not be.
• 🔧 Hardware damage: If the flash doesn’t work even in flashlight mode, repairs are required.

💡

On infrared flash devices (such as the Redmi Note 8 Pro), flashing when calling may not be available due to hardware limitations. LED-indicator (if any) or vibration.

6. Additional features: synchronization with melody and color effects

Some Xiaomi models (such as the Xiaomi 12S Ultra or Poco F4 GT) have advanced light display settings available.

• 🎵 Synchronize blinking with the ringtone: the flash will pulse in the beat of music.
• 🌈 Set up color schemes: for example, red for work calls, green for personal calls.
• ⏱️ Set timer: disabling flashing through 20/40/60 seconds.
• 📵 Use in silent mode: only visual alert.

To activate these functions:

1. Install the Flash Alerts 2 app (described above).
2. Go to the Advanced Settings section.
3. Activate the Music Sync Flash option to sync with the melody.
4. In Color Settings, select the color scheme (available on devices with RGB-flash).

On front-flash models (such as the Xiaomi Mi 11 Lite), you can set up the blinking of both LEDs at the same time. In Flash Alerts 2, activate the Dual Flash option.

7.Battery savings: how to reduce energy consumption

The constant flashing increases battery consumption by 5-15% (depending on the model) to minimize the impact on autonomy.

• ⚡ Reduce the brightness to 50-70% in the app settings.
• ⏳ Reduce the time of blinking: set the timer for 15-20 seconds.
• 🔄 Disable for unnecessary contacts (such as spam calls).
• 📴 Use it. LED-indicator instead of flash (if it is on the device).

On the tests Xiaomi Redmi Note 11 Pro+ with activated flash flash (brightness 80%, time 30 seconds) battery consumption was:

• 🔋 10 calls a day → +3-5% of the cost
• 📞 20 calls a day → +8-12% of the consumption
• ☎️ 30+ day-calling → +15-20% of consumption

⚠️ Warning: On devices with a small battery (less than 4,000 mAh), a constant flash blinking can reduce battery life by 1-2 hours.

8. Comparison of methods: which way to choose

Each of these methods has its pros and cons, depending on the phone model, the MIUI version and your technical skills.

For most users, Flash Alerts 2 is the best option. The app is simple to set up, stable and offers maximum customization. If you prefer a "clean" solution without third-party software, try it. ADB-Method or standard settings (if available).

💡

On MIUI devices for POCO (like the Poco X5 Pro), the standard flash blink option may be called Strobe Light and is located in the Display Settings section.
