How to set up a flash on Xiaomi so it flashes when calling: 3 working ways

Do you miss important calls because you can’t hear them in a noisy room? Or just want to make your Xiaomi more visible? The flash flash feature on incoming calls is not only a stylish accent, but also a useful tool for those who miss calls. In this article, we’ll look at all the possible ways to activate this feature, from standard MIUI settings to hidden features for advanced users.

It’s important to understand that not all Xiaomi models support this feature out of the box. For example, the budget Redmi 9A or POCO M3 may not have an integrated option, while flagships like Xiaomi 13 Ultra or Black Shark 5 Pro offer advanced customizations. We’ll look at solutions for everything from official methods to workarounds using third-party applications.

Method 1: Standard MIUI settings (for supported models)

The easiest way is to use the built-in features of the system, which is available on most devices with MIUI 12 and later, but its location on the menu may vary depending on the firmware version.

To activate flash flashing:

1. Open Settings → Special Opportunities
2. Select the Hearing section (on some models – Sound and Vibration)
3. Find the option Flash at notifications or Light indication
4. Activate the switch and select Calls in the event list

On some devices (such as Xiaomi 12T or Redmi Note 11 Pro+), this path may look different:

Settings → Notifications → Additional settings → Flash at notifications

Once activated, check the function: ask someone to call you or use a second phone. The flash should flash at about 1 time per second during an incoming call. If the blinking is too frequent or infrequent, you can adjust it in additional settings (if available for your model).

Method 2: Use Flash Alerts 2 (for all models)

If your device doesn’t support the flash feature built-in, the best solution is the third-party Flash Alerts 2 app. It works on all Xiaomi smartphones, including models without official support for this feature.

Instructions for setting:

• 📥 Download Flash Alerts 2 from Google Play
• 🔧 Open the application and provide all the permissions requested (camera, notifications, auto-run)
• ⚡ Turn on the Flash on Call (flash on call) switch)
• 🎨 Customize the color and frequency of blinking in the Customization section

Features of the annex:

⚠️ Note: On some models (e.g, POCO X3 Pro) the application may conflict with system notifications. If the flash does not work, check the autorun settings in Settings → Annexes → Application management → Flash Alerts 2 → Auto-start.

Method 3: ADB-Teams for Advanced Users

If you're not afraid to work with ADB, you can activate hidden flash functions even on devices where this option is disabled by default, a method that requires a computer and basic command-line knowledge.

Step-by-step:

1. Install ADB Tools on your computer
2. Enable USB Debugging on your phone (Settings → About Phone → MIUI version – press 7 times, then go back to Additional Settings → Developer)
3. Connect your phone to your PC and execute the command:

adb shell settings put system notification_light_pulse 1

To check the current state, use:

adb shell settings get system notification_light_pulse

If the command returns 1, the function is activated, and some devices may require an additional command to turn on the flash (not the LED):

adb shell settings put system camera_double_click_power_key 1

💡

Before working with ADB, back up your data. Incorrect commands can cause system failures.

⚠️ Attention: On devices with MIUI 14 and newer some ADB-In this case, try using the adb shell pm grant to provide additional permissions to the Flash Alerts 2 application.

Problems and Solutions: Why the Flash Does Not Blink

Even after you set it up properly, it may not work, and here are the most common reasons and ways to fix them:

• 🔋 Low battery (less than 15%) – the system automatically turns off the flash to save power. Charge the device or turn off battery optimization for the Flash Alerts 2 app.
• 📱 Power saving mode - turn it off in Settings → Battery or add the app to exceptions.
• 🔒 Lack of permissions – check that the app is granted camera rights, notifications and auto-run.
• 🛠️ Damaged firmware - if after updating MIUI the built-in function has stopped working, try resetting to factory settings (Settings) → The phone. → Resetting settings).

For devices with AMOLED-screens (e.g. Xiaomi 12 or Redmi) K50 Pro) there is an alternative, which is to use the screen as a flash, and this is enabled in a special feature setting called Screen Flash, which will flash white when you make an incoming call, which is less noticeable during the day, but works well in the dark.

How to turn off flash flash flash when calling

If you don't need it anymore or you start draining the battery, you can deactivate it easily, depending on how you turn it on.

• 🔄 Standard setting MIUI: Back to Settings → Special facilities → Hear and turn off the flash at notifications.
• 📱 Flash Alerts 2: Open the app and deactivate the Flash on Call switch.
• 💻 ADB-Execution of adb shell settings put system notification_light_pulse 0.

After turning off, check if there are any active processes consuming the battery. Go to Settings → Battery → Battery Use and find Flash Alerts 2 in the list. If the application continues to consume charge, delete it or limit background activity.

The effect on the battery: whether to use this feature constantly

Flash flashing on calls does affect battery consumption, but it's not as critical as it might seem.The Xiaomi 11T Pro with active function tests increase energy consumption by about 3-5% in 8 hours of standby. That's a negligible convenience charge, especially if you're not getting dozens of calls a day.

Optimization tips:

• ⚡ Use the function only at the necessary hours (set the schedule in Flash Alerts 2).
• 🔋 Turn off blinking when connected to the charger (this is useless when the phone is lying on the table).
• 📊 Follow the applications in the Settings section → Battery → Battery utilization.

On devices with a small battery (less than a small battery) 4000 mAh) constant flashing flash can reduce battery life on 10-15%. This is especially true for models like Redmi. 9C or POCO C31.

Alternative ways to avoid missing a call

If flash flashing doesn’t suit you, consider other options:

• 🔔 Loud Melodies: Set maximum volume for calls to Settings → Sound.
• 📳 Vibration incremental: Include in Settings → Sound. → Vibration on the bell → Growing.
• 🎵 Individual ringtones: Assign unique tunes for important contacts.
• 📱 Always on Display: On devices with AMOLED-screens show notifications of missed calls (included in Settings) → Screen. → Always On Display).

Xiaomi users with MIUI 13/14 have a Smart Assistant feature that can remind them of missed voice calls. This is activated in Settings → Special Features → Smart Assistant.

Make sure the battery is more than 20% charged.

Check the performance of the flash in manual mode (camera → flashlight)
