• 🔧 Activate the option and adjust the color/blinching interval.

Setting up a flash for individual applications

1. Open Settings → Notifications and Status bar → Notification light indicator.
2. Click App Setup.

Problem Solving: Why doesn’t flash on notifications work?

If you have enabled the function but the flash does not work, check the following points:

• 🔋 Battery level: when <15% function is automatically disabled.
• 🔕 Do Not Disturb: Turn it off in the notification curtain.

• 🛠️ Firmware damage: if the phone has undergone unofficial modifications (for example, custom recovery installation).

A critical feature of the Redmi Note 9 Pro is that the flash doesn’t work if the phone is upside down (the proximity sensor blocks the function).This is done to save battery power. To get around the restriction, turn off the proximity sensor via the engineering menu (#6484## → Proximity Sensor → Disable), but note that this may affect the operation of calls.

⚠️ Warning: If the screen does not go out during the call after the proximity sensor is turned off, return the settings back. Otherwise, you risk accidentally pressing the buttons with your cheek.

1. Check the flash operation manually (open the Camera and turn on the flashlight).
2. Reset the Settings app settings (Settings → Applications → Application Management → Settings → Storage → Clear data).
3. Install an alternative launcher (like Nova Launcher) and check if it conflicts with system notifications.

1. Go to Settings → Screen → Ambient Display
2. Enable the option of New Notifications.
3. Choose a display style (e.g. Color for better visibility).
4. In the Applications section, specify messengers for which you need to activate the backlight.
