How to turn on a flashlight on a call on Xiaomi: all ways + error solving

Are you missing important calls because the phone is screen down or in a noisy room? The flashlight feature on incoming calls on Xiaomi (including Redmi and POCO) solves this problem — a bright flash will catch your attention even in your pocket or bag. But where is this setting hidden in MIUI 14/15, and why might it not work on some models?

In this article, we have 3 proven ways to turn on a flashlight on your call (including hidden settings for older versions of MIUI), a table of model compatibility, and solutions to typical problems from the lack of an option on the menu to a conflict with energy saving. If your Xiaomi ignores the settings, here you will find the cause and fix.

Why the flashlight on the bell does not work on Xiaomi: 5 reasons

Before you set up the function, check if one of these problems is blocking it:

• 🔋 Energy saving regime: MIUI Automatically disables background processes, including flashlight control, when the battery is low (less than 15%).
• 📱 Outdated firmware: On MIUI 12 The option may not be available or may not work smoothly (especially on Redmi budget models). 9A/8A).
• 🔧 Application Conflict: Third-party launchers (like Nova Launcher) or optimizers (like Greenify) can block system notifications.
• 🛠️ Hardware limitations: On some models (e.g, POCO M3) flashlight doesn’t physically support fast blinking because of camera drivers.
• 🔄 Resetting settings: After the update MIUI or reset to factory settings, the parameter may return to the default value (off).

If your smartphone falls under at least one of the points, first eliminate the cause, and then move on to the setting. For example, for the Redmi Note 10 with MIUI 14, it is enough to turn off power saving for system applications - the instruction below.

Method 1: Standard configuration with “Special Opportunities” (MIUI 13–15)

This is the main method that works on most modern Xiaomi devices (2020 and later), the instructions are relevant for MIUI 13-15 firmware, including global and Chinese versions:

1. Open the Settings. → Special facilities.
2. Scroll down and select Notifications → Flash at Notifications.
3. Activate the flash switch when calling.
4. (Optional) Adjust the flash color (white/color) and the flash frequency (fast/slow).

On some models (e.g. Xiaomi 13 Pro), the path may be different: Settings → Additional → Notifications → Flash. If no point – see alternative methods.

Method 2: Hidden settings for older versions of MIUI (up to 12.5)

On Xiaomi smartphones from 2018 to 2019 (e.g. Redmi Note 7, Mi 9), the option can be hidden to activate:

1. Install Activity Launcher from Google Play.
2. Open the app and find it in the list of com.android.settings.
3. Inside the section, find the activity of.notification.LightSettings and run it.
4. In the menu that opens, activate the Flash when calling.

Important: This method requires developer rights, so if you reset after you reboot, use the third method.

Method 3: Forced Entry Through ADB (for Advanced)

If standard methods don’t work and the feature is physically supported by your model (check the compatibility table), you can turn it on via ADB. This method is suitable for Xiaomi with an unlocked bootloader or root rights.

Instructions:

1. Install ADB Tools on your PC.
2. Connect your phone to your computer and allow debugging over USB (Settings → About Phone → MIUI Version → 7 times click to activate Developer Mode, then Settings → Additional → Developers → Debugging over USB).
3. Open the command line in the folder with ADB Enter: adb shell settings put global flash_notification_enabled 1
4. To adjust flash color (if supported): adb shell settings put global flash_notification_color 0xFFFFFFFF (where 0xFFFFFFFF — white).

After applying the command, restart the phone. If the flashlight does not blink, check the logs through adb logcat | grep "flash" - there may be a driver error.

💡

If ADB issues a device unauthorized error, reconnect the phone and confirm the debugging permission on the smartphone screen.
