Flash flash when calling Xiaomi? remove once and for all

Are you tired of the annoying flash blinking every time a call comes to Xiaomi?This feature, designed to alert incoming calls in noisy conditions, is often a source of irritation - especially at night or in dark rooms. Fortunately, you can turn off flash blinking in several ways, from standard MIUI settings to hidden settings and even commands via ADB.

Complicating the problem, different firmware versions (MIUI 12, 13, 14) and different models (Redmi Note 12, POCO X5, Xiaomi 13) may have different paths to shutdown. In this article, we’ll look at all the current methods, including those that are not documented in the official help, and you’ll learn why flashes can flash even after switching off in settings – and how to fix it.

Why flash flash flashes when calling: the logic of the function

Flash-blinking function (LED-It was introduced in Xiaomi as part of an alert system for hearing-impaired users or for use in noisy environments, but by default it is activated on most devices, regardless of the owner's needs:

• 🔦 Triggers: flash flashes not only when incoming call, but also when SMS, notifications from certain apps (such as WhatsApp or Telegram) if allowed in the settings.
• ⚡ Energy consumption: Despite being short-lived, frequent blinking can affect battery consumption (up to a point in time) 1-2% day-to-day with active use).
• 📱 Hardware limitations: on some models (e.g, POCO M4 Pro) flash flashes even when the screen is off unless the function at the kernel level is disabled.

I wonder what in MIUI 14 The logic of the work has changed: now the flash can flash in sync with the ringtone, which increases the annoyance effect. AMOLED-screens (e.g. Xiaomi) 12T) Sometimes there is a "ghost" flashing of the backlight of the screen - this is a separate problem associated with the display drivers.

Method 1: Standard disabling in MIUI settings

The most obvious method is to use the built-in options, but there are pitfalls: the path to settings may vary depending on the MIUI version and regional firmware.

For MIUI 12 and 13:

1. Open the Settings. → Sounds and vibrations.
2. Go to Call Notifications (or Call Notifications).
3. Find the flash or light indicator and turn off the slider.

For MIUI 14 (and HyperOS):

1. Go to Settings → Notifications and Control Panel.
2. Select Call Notifications.
3. In the Additional Settings section, find the Lighting Effects and deactivate the option.

⚠️ Note: On some devices (e.g. Redmi) 10C) This item may not be in the GUI. In this case, move to Method 2.

Method 2: Disconnection through "Special Opportunities"

If the standard path didn't work, try turning off the blinking through the special feature settings, which works even on custom firmware devices:

1. Go to Settings. → Special facilities.
2. Choose Hearing (or Audio/Visual Tips).
3. Find the option of flashing flash at notifications or visual alerts.
4. Turn it off and restart the device.

💡 Useful tip: If this section does not have the right option, try turning on and off the Hearing-impaired Mode. Sometimes this will unlock hidden settings of light notifications.

Method 3: Use ADB-Teams (for advanced teams)

If flash flashing is not switched off through the interface, the ADB (Android Debug Bridge) option remains, which requires connecting the phone to a computer, but is guaranteed to work on any Xiaomi device.

🔧 What's the matter:

• 🖥️ Computer with installed ADB Tools.
• 📱 Included Debugging by USB on the phone (in Settings) → The phone. → Version. MIUI Press 7 times, then return to the Additional Settings → For developers).
• 🔌 USB-cable (preferably original).

📌 Step-by-step instruction:

1. Connect your phone to your PC and open the command prompt (cmd on Windows or Terminal on macOS/Linux).
2. Enter the command to check the connection: Adb devices should appear serial number of your device.
3. Execute the command to disable flash flash flash: adb shell settings put global flash_notification_enabled 0
4. To apply the changes, restart your phone: adb shell reboot

⚠️ Attention: On some firmware (MIUI 14 China) this command may be reset after the system update, in which case repeat the procedure or use Method 4.

💡

If, after the execution, ADB-The blinking commands are not lost, check if it does not block the setting of a particular application (for example, Truecaller or Google Phone).

Method 4: Edit the build.prop file (risky method)

For users with unlocked bootloader and root rights, there is a radical way - editing the system file build.prop. This method irreversibly disables flash flash flash flashing at the firmware level, but requires caution.

⚠️ Warning: Incorrect editing build.prop can result in loss of communication or a cyclical reboot of the device!

🔧 Instructions:

1. Install a file manager with root support (such as Root Explorer or Mixplorer).
2. Go to /system/build.prop and open the file in the text editor.
3. Add a line to the end of the file: persist.sys.flash_notification=false
4. Save the changes, set resolutions 644 (rw-r--r---) and restart the device.

📌 Note: On some devices (Xiaomi) 11T, POCO X3 Pro) this parameter may be called otherwise:

ro.vendor.flashlight.notification=0

Check the relevance of the option for your model in forums (e.g. 4PDA or XDA Developers).

Method 5: Disconnection through third-party applications

If you don't want to go through the settings or use ADB, you can use third-party utilities.

• 📱 Flash Notification Off (from Google Play) – a simple utility to disable blinking without root.
• 🛠️ MacroDroid – allows you to create a rule that will block blinking when an incoming call is made.
• 🔧 Tasker – for advanced users (requires settings for triggers).

💡 How does Flash Notification Off work:

1. Download and install the app from Google Play.
2. Grant permissions to access notifications (Settings → Applications → Special Access → Access to Notifications).
3. Activate the Disable Flash on Call option.

⚠️ Note: Some apps (such as Truecaller or WhatsApp) may ignore these settings and still make the flash flash flash flash.

Why does the flash keep blinking after the shutdown?

If you have followed all the instructions, but the blinking is not gone, the reasons may be as follows:

• 🔄 System cache: Sometimes settings are reset after an update MIUI. Try clearing the cache in Settings → Annexes → Application management → Three points. → Clear the cache.
• 📲 Application conflict: Programs like Google Phone, Truecaller or Mi Dialer can have their own flash settings.
• 🔧 Firmware with bug: On some versions MIUI 13.5 and 14.0.3, there is a bug when the flash flash flashes despite the shutdowns.

🔍 Diagnostics:

1. Call your phone from another device and watch for a flash.
2. If blinking only occurs with certain contacts, check the notification settings for those contacts in the Phone app.
3. If the flash flash flashes even when the screen is off, the problem with the LED driver is only firmware or ADB will help.

💡

If flash flashing is accompanied by vibration or sound that you also want to turn off, look for settings in Settings → Sounds and Vibration → Modes (for example, “Silent Mode” or “Do Not Disturb”).
