Flashing flash when calling Xiaomi Poco M3: 5 ways to set up notifications

Why the Poco M3 doesn’t flash when calling and how to fix it

Owners of the Xiaomi Poco M3 often face a problem: during an incoming call, the screen goes out, and the vibration or melody may not be noticeable enough in a noisy environment. The solution is to activate the flash flash, which will signal the call even in silent mode. However, in standard MIUI settings, this feature is not always available directly, especially on budget models like the Poco M3.

Reasons why the outbreak may not work:

• 🔹 There is no built-in option in the firmware (characteristically for the MIUI budget-smartphone).
• 🔹 Function disabled in special features settings.
• 🔹 Conflict with third-party management applications LED-indicator.
• 🔹 Hardware restrictions (on some Poco lots) M3 flash does not physically support frequent blinking).

In this article, we will discuss 5 working ways to enable flash flash flashing when calling, from standard settings to using hidden commands and third-party utilities. All methods are tested on the Poco M3 with MIUI 12.5-14 and do not require root rights.

Method 3: Applications for flash control

If the built-in methods didn't work, install one of the specialized applications. We tested them on the Poco M3 with MIUI 13:

• 🔦 Flash Alerts 2 is the most reliable solution with blinking frequency settings and support for notifications from messengers.
• 🔦 Flash On Call is a simple application with a minimalist interface, does not require root.
• 🔦 LED Blinker Notifications – Extended settings for flash and LED-The indicator (if it is on your model).

⚠️ Attention: After installation of the application is required:

1. Go to Settings → Apps → Permissions and give access to notifications.
2. In the application settings, tick Calls and SMS.
3. Add the application to the AutoRun list (in Settings → Battery), otherwise it will be closed by the system.

If the flash flash flash flashes too often after installing the application and drains the battery, reduce the blinking interval in the settings to 1-2 seconds.

1. Install the Light Manager application (link).
2. In the settings, select Call Notifications.
3. Assign a flashing color (e.g. green) and frequency.
4. Turn on the option to Ignore Do Not Disturb mode if you want the indicator to work always.

Frequent problems and their solutions

Even after setting up, flashing may not work properly, and consider typical situations and ways to fix them:

• 🔋 The flash flash flashes only when the charger is connected → Check your energy saving settings: add the flash control app to exceptions (Settings) → Battery → Optimizing the battery).
• 📵 Blinking too weak or intermittently → In applications like Flash Alerts 2, increase the flash duration to 300-500 ms.
