Flash when calling Xiaomi Redmi Note 8 Pro: how to turn on in 2 minutes

A flash flash on an incoming call or notification is a useful feature for those who often miss a call in a noisy room or want to visually distinguish important notifications. On the Xiaomi Redmi Note 8 Pro, this option is hidden in the depths of MIUI settings, and many users do not even know it exists. Unlike the iPhone, where the flash is activated via Universal Access, on Xiaomi devices, the path is more confusing — especially if you do not have the latest version of the firmware.

In this article, we’ll look at all the ways you can turn on a flash on a call, from standard MIUI settings to alternative methods using third-party apps. You’ll learn why the feature may not work even after activation, how to check for compatibility with your version of MIUI, and what to do if the flash flash flash flashes too weak or blinds your eyes.

If you're looking for a way to make your smartphone more visible in moments of important notifications, you're right here. It's going to take less than 5 minutes to set up, and it's going to be a joy every day, and then you're going to have step-by-step instructions that take into account all the pitfalls of MIUI.

1. Standard method: setting up through "Special features"

The most reliable way to turn on flash calls is to use the built-in MIUI tools, but the path to this feature is not obvious: it is hidden in the section for people with disabilities.

Open Settings → scroll down to System and Device → select Special Features. Here we are interested in the Hearing subsection (on some versions of MIUI it may be called Audio/Visual prompts). If you don't see this item, then your firmware is outdated - update it or use alternative methods (about them below).

Inside the Hearing section, find the Notification Flash option (sometimes called Light Alerts). Activate the slider. The system will prompt you to select the types of notifications that the flash will work for:

• 📞 Calls - blinking when incoming call
• 📩 Messages -- they work on SMS and notifications from messengers
• 🔔 Other notifications – all other push messages

By default, the function works only when the screen is locked. To flash always (even when you use the phone), turn on the additional switch Works when the active screen - it will appear after the main option is activated.

2.Why the outbreak doesn't work: 5 common causes

Even after you set it up properly, the feature may not work, and here are the most common reasons and ways to fix them for the Redmi Note 8 Pro:

Pay special attention to energy saving modes. On the Redmi Note 8 Pro, the flash function is often blocked when notified by battery optimization.

1. Go to Settings → Battery and Performance
2. Choose Battery Optimization
3. Find the phone application in the list and install it without restrictions

💡

If the flash flash flashes too bright at night, stick a translucent tape over it - this will reduce the intensity of the light without losing functionality.

Alternative method: “Flash Alerts 2”

If the standard feature doesn’t work or isn’t in your version of MIUI, a third-party Flash Alerts 2 application will come to the rescue.It doesn’t require root rights and works on all Xiaomi models, including the Redmi Note 8 Pro.

• 🔄 Flexible blinking frequency setting (1 to 10 times)
• 🎨 Choosing the flash color (if you have one) RGB-lighting)
• 🔔 Separate settings for calls, SMS and every messenger
• 🔋 Option to turn off at low battery charge

To set up the application:

1. Download Flash Alerts 2 from Google Play
2. Open the app and provide all the permissions requested (access to notifications, camera)
3. In the main menu, activate the Enable Flash Alerts switch
4. Go to Call Alerts and set up the settings for calls

For stable operation of the application, add it to the autoload:

1. Open Settings → Applications → Application Management
2. Find Flash Alerts 2 and select AutoRun
3. Activate all available permissions

Install the app from the official store |Give access to notifications |Enable autostart in the MIUI settings |Test with a call from another phone |Configure power saving exceptions-->

4. Configure via ADB (for advanced users)

If you're not afraid of the command line, you can activate the flash on your ADB calls -- it works even on custom firmware.

• 🖥️ Computer with installed Xiaomi drivers
• 🔌 USB-cable (preferably original)
• 📱 Included debugging by USB phone-on

Step-by-step:

1. Activate Developer Mode: Go to Settings → About Phone and Tap on MIUI Version 7 Times
2. Return to Settings → More → For developers and enable USB Debugging
3. Connect your phone to your PC and confirm your trust in the device
4. Open the command line (Windows) or the terminal (Mac/Linux) Enter: adb shell settings put global flash_notification_enabled 1
5. To apply the changes, restart the phone

To disable the function, use the command:

adb shell settings put global flash_notification_enabled 0

5. Features of work on custom firmware

If your Redmi Note 8 Pro runs on an unofficial firmware (like LineageOS, Pixel Experience, or HavocOS), the standard flash-on method may not work.

First, check if the feature is in the firmware settings, and it's often in the Display → LED/Notification Light section, and if it's not, you'll have to use one of the solutions:

• 🔄 Install a Magisk module called FlashLight Alert (requires root)
• 📱 Use Flash Alerts 2 (works without root, but may require additional permissions)
• 🔧 Manually edit the build.prop file by adding a line ro.config.flash_notification=true

On firmware like Pixel Experience, the flash feature is often integrated into the system, but is called differently – look for Ambient Display → Flash notifications. If the flash does not flash after activation, check if it conflicts with other Magisk modules (for example, ViPER4Android).

💡

On custom firmware, first check for the feature in standard settings – often it’s simply renamed or moved to another section.

6.How to calibrate the brightness and frequency of blinking

A flash that is too bright or frequent can be annoying - especially at night. On the Redmi Note 8 Pro, you can fine-tune the blinking settings:

If you use the standard MIUI function:

1. Go to Settings → Special features → Hearing → Flash at notifications
2. Click on Settings (cog in the upper right corner)
3. Adjust Flash Brightness slider (not available on all versions of MIUI)
4. Set the frequency of blinking (optimally - 2-3 times with an interval of 1 second)

For the Flash Alerts 2: app

1. Open the app and go to Advanced Settings
2. In the Flash Duration section, set the blinking duration (recommended 200-300 ms)
3. In Flash Interval, set the pause between blinking (optimally 500-700 ms)
4. Activate Adaptive Brightness to automatically adjust brightness

💡

To save battery power, set the flash to flash only for the first 10 seconds of the call. This is enough to attract attention, but will not drain the battery.

7.Safety: When an outbreak could harm

While flashing is very useful, in some situations it is better to turn it off.

⚠️ Warning: Do not activate flash on notifications if you or others have epilepsy or light sensitivity.Frequent flashing of bright lights can trigger an attack.

Other risks:

• 🔋 Increased battery consumption – constant blinking discharges the battery 5-10% faster
• 📸 Camera overheating – prolonged flash operation can temporarily degrade photo quality
• 🚗 Distraction behind the wheel – if the phone is lying on the torpedo, blinking can interfere with the driver
• 🛌 Insomnia – bright flashes at night disrupt melatonin production

To minimize the negative effects:

• Turn off the function at night or use the "Do Not Disturb" mode.
• Reduce the brightness of the flash to a minimum comfortable level
• Do not put your phone flashing down on soft surfaces – it can cause overheating
