Modern Xiaomi smartphones have a huge number of hidden features that often go unnoticed by users. One of these useful options is the ability to activate the LED flash during an incoming call. It is not just a beautiful visual backlight, but also a practical tool for people with hearing impairments or for those who are in noisy places where the sound of the call may not be heard. In this article, we will discuss in detail how to turn on the flashlight on Xiaomi when calling using standard tools of the MIUI and HyperOS system.
It’s worth noting that the functionality may vary slightly depending on the operating system version and the specific model of your device. However, the basic principles of customization remain the same for the entire ecosystem of the Chinese manufacturer. We will look at both the software settings and the possible limitations imposed by the hardware in some budget segments. Understanding these nuances will help you avoid confusion and quickly adjust the desired effect.
Before you get to the front, make sure your phone is fully functional and working correctly. If you've just upgraded to a new firmware version, some menu items may have changed their location. System changes to MIUI shells often take functions to new sections, so it's important to navigate not only by name but also by the meaning of the sections.

Standard Notification settings in the MIUI shell
The first and most obvious way to activate a flash is to use the built-in capabilities of the system. In most current versions of the MIUI shell and the new HyperOS, this feature is hidden in the special features section. You do not need to install third-party applications, since the developers have already foreseen this use case.
Find a section called "Additional Settings" or "Special Features." Depending on the regional firmware (Global or Chinese), the name may vary. Inside this menu, look for the item associated with auditory or visual notifications. That's where the light display switch is hidden, and activating this slider is the first step to setting up.
- 🔦 Open “Settings” and go to the “More” section».
- 🔦 Select the option “Accessibility).
- 🔦 Find the “Hearing” or “Notification” tab».
- 🔦 Activate the “Flash for notifications” switch».
Once this feature is enabled, the phone will start to blink to any incoming events, including calls and messages. However, the standard setting often works in "blinking" mode, which may not always be convenient. Some users prefer to have the flashlight light up and burn constantly while the call is going on, or flash at a certain rhythm.
💡
The standard MIUI feature activates the flash for all notifications at once, without the option of selectively configuring just for calls.
Using the “Themes” app to visualize calls
Xiaomi's ecosystem is famous for its store-like features that allow for dramatic changes in the look and feel of the interface, but what few people know is that many themes contain not only new icons and wallpaper, but also custom inbound screens. Some of them include sophisticated animations using an LED flash, which is a great way to combine the good with the good.
To find the right design, open the standard Themes app. In the search bar, type in flash or light calls. You'll see a variety of options where flash effects are indicated in the description. When you install such a theme, the system may request additional permissions to use hardware components, which is normal behavior for this type of content.
It is important to understand that topics can affect battery consumption in different ways. If you choose a topic with a flashlight burning during a conversation, the battery will run out faster. In addition, some topics may conflict with the notification system settings, so after installation, it is recommended to conduct a test call. If the effect does not work, try restarting the device.
Why do some topics not work?
Application of third-party applications from Google Play
If built-in tools are not enough and you want to have full control over the flashlight's behavior, specialized applications from the Google Play store will come to the rescue. There are many utilities, such as Flash on Call or LED Flash for Alerts, that intercept the incoming call signal and control the flash using specified algorithms, which gives flexibility not available in standard settings.
Once you install an app, you'll need to give it a number of critical permissions, without access to a phone or a camera, it won't know when to turn on the lights, and be careful when granting rights: trust only trusted, highly-rated developers to avoid putting personal data at risk of leakage.
☑️ Setting up a flash app
The advantage of third-party solutions is that you can customize the blinking patterns, so you can have the flashlight flash twice quickly, then pause, or only turn on contacts from a certain list, and this is especially useful for identifying the caller without having to look at the screen or pull the phone out of your pocket, but it's worth remembering the potential conflict of these applications with energy-saving modes of the system.
Configuring flash modes
Once you have chosen the activation method (standard or through the application), you need to decide on the mode of operation. In specialized applications, the settings are usually divided into several categories: “During the call”, “After the answer”, “For those who are missed”, This allows you to create a complex logic of device behavior that will be most comfortable for you.
While ringing makes the flashlight blink or burn until you pick up the phone. This is the most popular option. Permanent mode can be useful in the dark when the phone is on the table, and it serves as a kind of nighttime indicator. However, using a constant glow can greatly heat the case of the smartphone in the area of the camera.
| Mode of work | Description of behaviour | Impact on the battery | Recommended use |
|---|---|---|---|
| Blink (Blink) | Short-term intermittent flashes | Low. | Daily use, energy savings |
| Permanent (Solid) | Continuous burning before response | High. | Noisy places, poor vision |
| Pulse (Pulse) | Smooth build-up and attenuation of light | Average. | Aesthetic effect, at night |
| SOS | Signal rhythm (three short, three long) | Average. | Emergency situations, attracting attention |
When choosing a mode, consider the operating conditions of the phone. If you are often in the bright sun, the pulsation mode may be invisible, and it is better to choose aggressive blinking. At home, on the contrary, bright constant light can be annoying, and then a soft blink is preferable. Experiment with settings to find the perfect balance.
The impact of energy saving mode on the operation of the flashlight
The MIUI shell is known for its aggressive power optimisation, which can force the system to shut down background processes and restrict access to hardware components if it thinks an application is consuming too much resources, often causing a customized flash to stop working suddenly or to run unstablely.
To avoid this, add the app you are using (or the system notification process) to the exception list. Go to the battery settings, find the app, and select the option “No restrictions” or “Out-start” that will give the program the right to run in the background and use the LED module even when the screen is off.
⚠️ Warning: Turning off power saving restrictions for a large number of applications can lead to a significant reduction in the battery life of the device.
It’s also worth checking if the phone is running a general Power Saving or Ultra Saving mode, which blocks most background activities, including visual notifications. If it’s critical to see a flash, make sure the phone is running in Performance or Balanced mode.
Removal: Why the outbreak doesn't work
Even with the right setup, users may encounter a situation where the flashlight does not light up. One of the common causes is application conflict. If you have multiple call management or flashlight programs installed, they can block each other. Try removing unnecessary utilities and leaving only one main one.
Another reason is the physical feature of the model: some Xiaomi smartphones (especially older or ultra-budget models) do not have the hardware ability to use the camera flash as a notification indicator, despite the presence of a software function. In such cases, the system simply ignores the on command. Check the specifications of your model on the official website.
- 🔦 Check if the camera lens is covered with a cover or finger.
- 🔦 Make sure that the “Do Not Disturb” mode is not activated».
- 🔦 Restart the device after making changes to the settings.
- 🔦 Check for system updates in the About Phone section».
If nothing works, try resetting special features to factory values. Sometimes, system configuration files can have errors that can only be solved by completely resetting availability, and this won't delete your personal data, but will return all interface settings to their original state.
💡
When you use flash as a call indicator, keep an eye on the temperature of the body in the area of the camera. Prolonged heating can reduce the life of the LED module.
