How to turn on flash when calling Xiaomi Poco X3 Pro: 3 working ways

Xiaomi Poco X3 Pro is one of the most popular smartphones among gamers and fans of powerful equipment at an affordable price. But even such a “charged” model sometimes hides useful features that users do not immediately learn about. One of them is the flash of the camera when an incoming call or notification is sent, which helps not to miss an important call in a noisy room or when the phone is lying down.

You can turn this option on in just a few taps, but not everyone knows where it hides in the MIUI firmware. Moreover, there are three ways to activate it on the Poco X3 Pro at once – through standard settings, using the developer mode and even through third-party applications (if the first two options did not work).

Important: the function only works when the rear flash is active – if the LED is damaged or turned off at the system level (for example, after an informal firmware), none of the ways will help. Also check that the phone does not have an energy-saving mode that can block additional lights.

1. Standard method: through notification settings

The easiest and safest method is to use the built-in MIUI options, which is suitable for most users and does not require superuser rights or changes to system files.

1. Open the Settings app (the gear icon on the home screen).
2. Go to the Notifications and Status bar section.
3. Select Flash when notified (in some versions of MIUI it may be called Flashlight).
4. Activate the switch next to the Incoming Calls option.
5. Optionally: Turn on the flash for Messages or other notifications.

If you don't have Flash notifications on your menu, it's hidden because of regional firmware restrictions or MIUI versions.

Make sure the rear flash is working (test it in the camera app)

Turn off the power saving mode in Settings → Battery

Check that the latest version of MIUI is installed on the phone.

Nuance for Poco X3 Pro: Some firmwares have a flash option tied to Special Options. If you don't find it in notifications, try the path:

Settings → Special features → Hearing → Flash at notifications

2. Alternative method: through the developer mode

If the standard method didn’t work, you can try activating the function through hidden settings for developers.This method requires a little more action, but often helps on custom firmware or after resetting.

First, you need to turn on the developer mode:

1. Go to Settings. → The phone.
2. Find the MIUI version and tap it 7 times in a row (you will be notified “You became a developer”).
3. Go back to the main settings menu and open a new section for developers.

Now we're looking for the flash option:

1. In the For Developers section, look for Flash at Notifications (could be called Notification Light or Notification Light). LED-indicator).
2. Activate the switch and select Incoming calls.
3. Save the settings and restart the phone.

On the Poco X3 Pro with MIUI 12.5+ firmware, the option may not be available even in developer mode, which is a feature of a particular model, so move on to the third method.

3. Third-party applications: if nothing works

If the first two methods fail, Google Play apps will come to the rescue, mimicking the system flash and often saving on devices with limited firmware. X3 Pro:

• 🔦 Flash Notifications is a simple application with flexible settings (you can choose the color, flash frequency and applications for which the flash will trigger).
• 📱 Flash Alerts 2 – supports not only calls, but also notifications from messengers (WhatsApp, Telegram, etc.).
• 💡 LED Blinker Notifications – Advanced settings with pre-saving testing.

How to set up (for example, Flash Notifications):

1. Install the app from Google Play.
2. Open it and provide all the permissions you request (access to notifications, camera).
3. Enable the Enable Flash on Call switch.
4. In the Apps section, select which applications the flash will work for (calls, SMS, instant messengers).
5. Adjust the blinking frequency in Flash Settings (recommended 1-2 blinks per second to avoid planting the battery).

⚠️ Note: Some applications may conflict with system notifications MIUI. If after installation, notifications from messengers stopped coming, disable the flash function for them or use another application.

Possible problems and solutions

Even after setting it up properly, the flash may not work, and let's look at the typical causes and ways to fix them:

⚠️ Note: If after the update MIUI If the flash stops working, reset the notification settings to the factory. → Annexes → Application management → Three dots (menu) → Resetting your application settings. It won't delete your data, but it will return all permissions to default».

5. How to turn off the flash when calling

If the function is too intrusive (e.g., the flash is triggered at night and wakes others up), it is easy to deactivate, depending on how you turn on the option:

• 🔄 With Standard Settings: Return to Settings → Notifications → Flash at notifications and turn off the switch.
• 🛠️ Through Developer Mode: Go to Settings → For developers and deactivate the Flash option at notifications.
• 📱 Through a third-party app: Open it and uncheck the box from Enable Flash on Call.

If the flash continues to flash after turning off, check:

• Are there other notification management applications installed (e.g. Light Manager or Notification LED)?
• Is the function activated in several places at the same time (for example, in the MIUI settings, and in third-party software).

💡

Create a shortcut to quickly turn on/off flash: add the Flash Notifications app widget to the home screen, so you can control the function in one tap without going into the settings.

Energy consumption and battery impact

Many users fear that flashing constantly at notifications will quickly drain the battery. In practice, the effect is minimal: the LED consumes ~0.1-0.3 W per actuation, which is comparable to the operation of the proximity sensor.

• 🔋 Blinking frequency: if you set up 5-10 blinks in a row, battery consumption will increase by 1-2% per day.
• 📉 Temperature: during prolonged operation, the flash can heat up, which temporarily reduces the battery capacity (the effect is reversible after cooling).
• ⚡ Battery mode: If Ultra Mode or Energy Saving is activated, the system can block the flash to save charge.

To minimize the impact on the battery:

• Set no more than 2-3 blinks per notification.
• Turn off the flash for unnecessary apps (such as games or social networks).
• Use the feature only during daytime (some apps have a schedule).

💡

A flash on a Poco X3 Pro uses less power than 1 minute of active camera use, and at moderate settings (1-2 blinks), the effect on the battery does not exceed 0.5% per day.

7. Comparison with other Xiaomi models

The flash notification function is implemented differently on Xiaomi devices, and for comparison, we will give data on popular models:

As you can see from the table, the Poco X3 Pro is not the most “comfortable” smartphone in terms of setting up a flash – often requires activation of developer mode or third-party utilities. For comparison, on the Redmi Note 10 Pro or Mi 11, the option is available out of the box without additional manipulation.

If you are planning to buy a new Xiaomi smartphone and you are important to the flash function at notifications, pay attention to the models with the new smartphone. AMOLED-screens (e.g. Xiaomi 12 or Poco) F4). They support Always-On Display, which can replace flash, saving battery life.
