How to turn on flashlight flicker when calling Xiaomi

Modern Xiaomi and Redmi smartphones offer users a huge number of hidden features that allow them to personalize the device to their needs. One of these useful, but not always obvious features is activating the camera flash during an incoming call. This solution is especially important for people with hearing impairments, as well as for those who are often in noisy places or carry a phone in a bag where the sound may not be heard.

Unlike older phones, where a special LED was responsible for blinking, in modern models, the main camera module takes this role. The standard MIUI or HyperOS shell does not always have a direct button to enable this option in the basic call menu, which often confuses users. However, using system settings or special codes, you can activate this mode without installing third-party software. We will analyze all available methods, from simple switches to hidden engineering menus.

It's worth noting that the name of the feature on the menu may vary depending on the firmware version and region, some of which is called "Flash at Notifications" and others are called "Event Indicator." Understanding these nuances will help you find the right setting faster. Next, we'll look at the algorithms for the different versions of the interface in detail.

Standard activation method through phone settings

The easiest and safest way to make a flashlight flash when you call is to use the built-in system settings. In most current Xiaomi shell versions, this switch is hidden in the special features section. You don't need to be a mobile technology expert to perform this setup. You just need to go consistently along the menu path.

To start, open the main settings menu of your device. Find a section called Additional Features or Advanced Settings. This is where you find options that are not in the main menu, but are important for comfort of use. Inside this section, you should look for Flash Activation or Flash at notifications.

After you go to the menu, you'll see a list of notification types. The system will tell you to choose which events the flashlight should respond to. There are usually options available for the camera, voice recorder and, most importantly, incoming call. You need to activate the switchboard opposite the "Incoming call" item.

☑️ Checking flash settings

Done: 0 / 1

It's important to understand that some global firmware versions may have a different name or not. If you don't find the path, try searching by settings. Type the word "flash" or "flash" into the search box and the system will tell you where the switch is hiding. It's a universal method for any Android smartphone.

Use of the Engineering Menu to Activate LED-indicator

If the standard path didn't work, the engineering menu comes to the rescue, and it's a hidden part of the system that's designed for testing by the factory's engineers, and it's accessed through a set of code in the Phone app, and beware, changing unknown parameters in this menu can cause the device to malfunction.

To enter the test menu, dial ##6484##. Once you enter the last star or grille (depending on the model), the test list will open. Find the item associated with LED or Flashlight. Here you can check the module's performance and, in some cases, force the flashing mode to be activated.

However, there is a more specific code that directly opens the flash notification settings menu, bypassing long searches in the settings.

##64663##

In the list that opens, look for the section associated with Notification LED or Call Flash. If your model supports software management of this setting through an engineer, there will be a corresponding switch. Once activated, be sure to restart the device so that the changes take effect.

⚠️ Warning: The engineering menu is a tool for the professionals. Don't change the values in sections you don't know the purpose of, especially when it comes to screen or battery calibration.

It is worth remembering that on new HyperOS models, access to some engineering codes may be restricted by the manufacturer for security reasons, and if the code does not work or gives an error, then this method is not available for your version of the software and other methods should be used.

Configure through the application "Themes" and third-party solutions

Xiaomi’s ecosystem is famous for its store-like features that allow not only wallpaper and icons to be changed, but also system sounds and effects. Some themes have a built-in flashlight feature that activates automatically when you install the design, which can be a workaround if the system settings are blocked by a carrier or region.

Go to the standard Themes app. Search for "Flash call" or "Flash call." See the descriptions of the topics: often authors indicate the presence of a Call Flash feature in the list of features. Once you install this theme and apply it to the system, check the incoming call.

If there's not enough built-in tools, third-party apps from Google Play come to the rescue. There are many utilities like Flash Alerts or Call Flashlight that take control of the LED, they work on top of the system and have more flexible settings:

  • 🔦 The ability to select the number of flashes before the response.
  • 🎨 Setting the flash color (if hardware is supported).
  • 🔇 Separate profiles for silence and vibration.
  • ⏱ Adjust the duration of one pulse of light.
The effect of third-party applications on the battery
Using flashing apps can increase battery consumption, as they are constantly hanging in the background and monitoring sensors. Try to choose applications with a high rating and a minimum set of resolutions.> When installing third-party software, the system will request a number of permissions. Be sure to give access to the phone and camera, otherwise the program will not be able to control the flash. Without these permissions, the functionality will be limited only to visual effects on the screen. The features of Do Not Disturb mode are designed to ensure that the phone does not distract the user with sounds and vibrations. However, visual notifications such as flashing will often remain an ideal function for a flash flash. To make sure that the flash will work when the phone is silenced, you need to check the settings of the "Do Not Disturb" mode itself. Go to Settings → Sound and Vibration → Do Not Disturb. Here you need to find a clause allowing visual notifications or repeated calls. In some versions of MIUI, the logic of the operation is as follows: if the sound is turned off completely, the flash may not work if it is not allowed explicitly. Check the table below for understanding the behavior of the system in different states: Phone Sound Vibration Flash (if it is on) Normal There is No Sound - There is No sound - There is a combination of the signal - If the network does not worrying, and the phone does not work. This allows you to avoid missing an important call from loved ones, even if the phone is on the screen down. Why the flash doesn't work: main reasons and solutions There are situations when all the settings are correct, but the flashlight does not light up. The first and most common reason may be the work of another application using the camera. If Skype, Telegram (during a video call) or the camera is opened, the system flash module is busy and can not be used for notifications. The second common problem is energy saving. Xiaomi's aggressive algorithms can "kill" the background processes responsible for monitoring incoming calls, especially if you use the application on the battery, you also select the physical mode on the phone. If the flash doesn't work even in the camera app, it might be hardware, and then the software settings won't work, and you'll need a diagnostic at the service center, and the other thing is video calls. When an incoming video call is made via messengers (WhatsApp, Viber), the system flash may not activate, as these applications use their own notification mechanisms. They often require separate configuration within the messenger itself. MIUI The interface of Xiaomi smartphones is constantly updated, and the location of the settings can change. MIUI 10-12 The feature was often available immediately in the call menu, in newer versions such as MIUI 13, 14 HyperOS, the developers hid this option deeper to avoid overloading the interface. On flagship models such as the Xiaomi 13 or 14 series, the implementation may differ due to the design features of the camera module. It is important not to confuse the “Ring-Break” function with the “Event Indicator”, which can be implemented through the glow of the logo or the edge of the screen (on models with curved displays). POCO Often there is no physical LED light, so a software flash is the only way to provide light alerts, and owners of such devices are advised to carefully check for system updates, as new security patches often expand the functionality. ⚠️ Warning: Frequent use of flash as an indicator can cause the camera module to heat up.Do not cover the phone with a cloth during long periods of waiting for a call if the function is active. If you have upgraded to a new version of Android or MIUI If you're not settings, check "Flash at Notifications" again. Updates often return settings to factory values. Frequently asked questions (FAQ) Does flashing a flashlight affect battery life? Yes, but only slightly. LED consumes little power compared to a screen or communication module. However, if the phone is lying idle and constantly blinking from notifications, this can add to the energy consumption of the LED. 1-2% You can't do that with standard Xiaomi tools. You can set up different blinking colors for different contacts. You can set up this in detail, you need to install third-party apps from Google Play that have access to the contact book and management. LED-Will the flash work if the phone is turned down. The proximity sensor, in this case, doesn't block the flash, because it's designed to attract attention when the user doesn't see the screen, and that's one of the main advantages of the feature. What if the flashlight flashes but there's no sound? Check if the silent mode or the "Do Not Disturb" mode is on, and also make sure the volume of the call is not turned to zero. The flash works regardless of the sound settings, so it can signal even a quiet call. 💡The flashlight flicker function when ringing is not just a decorative effect, but an important element of accessibility that can be vital for people with hearing impairment.
