How to make a flash on Xiaomi when calling: a step-by-step guide

Many smartphone owners face a situation where a missed call goes unnoticed due to loud music, noise in the street or simply because the device was lying down the screen. In such cases, the standard vibration or melody may not be effective, which is why the flash feature when calling becomes an indispensable tool for users who want to make sure that they do not miss an important conversation under any circumstances.

In Xiaomi smartphones running MIUI shells and the new HyperOS, the implementation of this feature may differ from standard Android. Often users look for this option in the general settings of the system, unaware that it may be hidden in specific application menus or require inclusion through third-party utilities. Understanding the logic of the system will allow you to quickly activate the desired mode.

In this article, we will discuss in detail all the available ways to activate light notifications. We will look at both the built-in system tools and the capabilities of the standard Phone application, as well as touching on the nuances of the function on different device models. This guide will help you customize the gadget as convenient as possible for everyday use.

Built-in MIUI and HyperOS functions

The first thing to start looking for a cherished setting is the system notification menu. In recent Xiaomi firmware versions, developers often change the layout of interface elements, so even experienced users should recheck the current paths. The function may be called differently, but the essence remains the same: LED lighting must respond to an incoming call.

Usually, the path to setup is to go to Settings → Notifications and Status bar. Here, you should carefully look at the list of options available. If you don't see a direct mention of a flash, try looking for "Event Notice" or "Lighting Indication." In some regions of the firmware, this functionality may be hidden or renamed.

It is worth noting that some global versions of the shells may not have this feature out of the box in the system menu, as the company's policy sometimes limits the use of the camera in the background to save battery power.

⚠️ Note: Using flash as an indicator greatly speeds up battery life.If you plan to use this feature all the time, make sure you have the ability to recharge the device during the day.

You can search the settings menu for a deeper setup, just type the word flash or flash into the search box, and the system will offer you the available LED backlight options, especially for new models that came out in 2026-2026, where the menu structure may have changed.

Configure via the phone application

The most reliable and common way to activate the flash on Redmi and Poco smartphones is to use the settings of the application itself for calls. The standard MIUI dialer has advanced functionality that allows you to control the behavior of the device during an incoming call.

To get to the settings, open the Phone app and find the menu icon, usually three dots in the corner of the screen or a gear settings, and in the list that opens, you have to select Incoming Calls, and that's where the flashing flashing flashing switch is hidden.

Once the Flash Incoming Call (or similar name) slider is activated, the system will request confirmation of access to the camera, which is a standard Android security procedure that must be adopted, and from now on, every time you call, the LED will give you light signals.

It's important to understand that this setting only works when the device's screen is turned off or locked. If you're using your phone when you call, the flash will generally not light up so as not to interfere with your view or distract from your current routine. It's a thoughtful interface logic.

Use of third-party applications

If the system failed to activate the feature, applications from the Google Play store come to the rescue. The market offers many utilities that take control of the flash, and they can be even more flexible in settings than standard Xiaomi tools.

One popular solution is the Flash Alerts app or its analogues, and once you install it, you don't have to look for hidden menus, but it creates its own layer on top of the system and responds to calls or messages by launching the camera using a given algorithm.

When using third-party software, you need to be careful about the permissions you request, the application needs to have access to your phone, contacts, and camera, and without those permissions, it can't properly handle the incoming call script.

• 📱 Flash Alerts 2 is a classic solution with a minimalist interface and low resource consumption.
• 🔦 LED Flash for Alerts – an application with advanced blinking pattern settings for different contacts.
• 📞 Call Flashlight – a utility that is specifically designed to control the flash during calls.

The use of such programs is especially relevant for older models of smartphones, where the manufacturer could programmatically limit the functionality of the camera in new versions of Android.

Table of compatibility of functions

Not all smartphone models support the flash in the same way. Below is a table that will help you navigate the capabilities of different Xiaomi series of devices.

As you can see from the table, the most versatile way is to configure through the Phone app. System setting in the general menu only appears on flagship models with the latest shells. For budget devices, reliance on third-party applications remains the only option if the standard dialer does not support the function.

It is also important to note that on devices with AMOLED-The light display may work differently in some cases, the system prioritizes the glow of the screen, ignoring the request to turn on the LED flash to save the matrix life.

Addressing problems and conflicts

Even with the right setup, users may find themselves in a situation where the flash does not light up, most often due to the aggressive MIUI energy saving system. The operating system can "kill" the process responsible for blinking, considering it an inactive background process.

To avoid this, you need to go to the battery settings and find an application that manages the flash (be it a standard dialer or a third-party program). In the autostart and background settings, you need to set a limit "No restrictions" to give the system a signal not to interrupt the utility.

Another reason could be a conflict with other apps that use the camera: if Instagram, Telegram (while recording a video) or an augmented reality navigator are running in the background, access to the LED can be blocked, in which case the flash on the call will not physically work.

⚠️ Note: Do not use flash as an indicator if your smartphone case completely covers the main camera module. In some dense cases, the light may not break out, creating the illusion of a malfunction.

Also check if Do Not Disturb or Sleep is on, and in these modes, the system can block not only sound, but also visual notifications, including lights, to keep the user awake.

Additional notification settings

Xiaomi's functionality allows you to flexibly configure not only calls, but also notifications from messengers. If you want to flash when you receive messages on WhatsApp, Telegram or Viber, you need to look deeper for settings. Often this requires activating the "Advanced Notifications" function in the corresponding part of the system.

New versions of HyperOS offer the ability to assign different blinking patterns to different contacts, a unique way to know who is calling without even pulling the phone out of your pocket, by going to Contacts, selecting a subscriber, and looking in their card for Melody and Vibration, where the light option may be hidden.

Remember to clear the cache of Phone and Google Play Services from time to time. Temporary files can cause system notifications to crash, and you can do this through the Settings menu → Apps → All apps.

💡

Use Pocket Mode with caution, if it's too sensitive, it can block the flash from turning on, believing that the phone is in a dark enclosed space.

For advanced users, you can customize scripts through the Auto Tasks app, and you can create an algorithm that says, "If it's 23:00 to 7:00 and there's an incoming call." → Turn on flash 3 times. This gives maximum control over the behavior of the device.
