Modern smartphones Xiaomi and Redmi are equipped with powerful LED-It's very easy to miss an important call, and it's very easy to miss an important call, in a noisy office, in loud music, or just when the phone is down. It is here that the flash function comes to the rescue when calling, which visually signals the incoming connection with bright pulses of light.
Activating this option can make you more accessible, but the standard MIUI or HyperOS shell interface sometimes hides the right switches in non-obvious partitions. Users often search for where this option is located, believing that it should be in the main audio settings, but the logic of the Android system is built differently. In this article, we will discuss all the activation methods, including hidden menus and third-party utilities.
It's worth noting that the behavior of the indicator can vary depending on the firmware version and the specific device model. On some devices, the flash only flashes during a conversation, on others - exclusively when a call is received. Understanding these nuances will help you avoid confusion and customize the gadget exactly as convenient for you.
Standard Activation through System Settings
The easiest and most reliable way to make a flashlight flash when you call is to use the phonebook's built-in functionality. In most current versions of the MIUI shell, this option is available by default and does not require superuser rights or additional software installation. You need to open a standard call app, which usually has a green handset icon on your desktop.
When you start the app, look at the settings menu, which is often hidden behind three dots or a gear in the corner of the screen, and that's where the advanced settings of the communication module hide, find the incoming call point, and activate the flash switch, which will instantly apply the changes to all incoming connections.
However, if you're using a stripped-down firmware or a global build with changes from a local distributor, the path may be different. Sometimes the option is in the general system settings rather than the call menu, so check Settings → Sound and Vibration → Inbound Call, which can also host the switch you're looking for.
If you didn’t find the switch in the places described, your version of Android may require a different approach, which we will discuss in the following sections.
Use of the "Themes" application for customization
A unique feature of Xiaomi’s ecosystem is the deep integration of the Themes app into the interface. Many users don’t know that some themes contain their own scripts for notifications, including flashing a flashlight. This is a great way to diversify the visual style of the device and get the right functionality where it is not in the drain.
To implement this method, open the Themes app and go to the search section, type keywords like "Flash call" or "Flash call" into the query bar, and you will be offered various design solutions that, when installed, can change not only the icons, but also the behavior of the system when the call is in.
⚠️ Warning: When installing third-party themes, always check the permissions they request. Some themes may require access to contacts or location, which is not always justified by their functionality.
Once you have applied the theme, you need to restart the device so that all changes take effect. If the blinking doesn't come right away, try making a test call from another number. Consider that the themes can affect the performance of the system, so choose proven options with high ratings from well-known authors.
What to do if the theme breaks the interface?
Setup through third-party apps from Google Play
In situations where embedded funds MIUI Not meeting your requirements or not, and specialized applications from the Google Play store come to the rescue. There are many utilities, such as Flash Alerts or Call Flash, that take control. LED-They're running on top of the system and they activate the flash when you log the call event.
When you install an app, you'll need to give it a number of permissions, including access to the phone and the state of the device, so that it can "hear" the incoming call and start the blinking algorithm, and without those permissions, the functionality won't work, because Android strictly controls access to the hardware modules.
Popular apps allow you to flexibly adjust blinking patterns: frequency of flashes, duration of glow and even color (if your smartphone has a multicolored light). LED-And a little bit of a light that's rare, but it's possible, and many of them are able to blink and when they arrive. SMS-Messages or notifications from messengers.
- 🔦 Flash Alert 2 is a classic solution with a minimalist interface and low battery consumption.
- 📞 Call Flash - Flash on Call - offers a wide range of effects and the ability to customize for different contacts.
- 💡 LED Flash Alerts is a universal tool that works even on a locked screen.
Using third-party software has one significant drawback: increased battery consumption, because the application must be constantly hanging in the background and monitoring events, it prevents the processor from going into deep sleep, so it is recommended to carefully select the program and check its effect on autonomy during the first days of use.
💡
Set a background activity limit for the flashing app in the battery settings so that the system does not forcefully close it, but also does not allow you to spend too much energy.
Specifics of the work in the mode "Do not disturb"
Special attention should be paid to the flash behavior in the activated Do Not Disturb mode. By default, when this mode is on, the system blocks all light and sound notifications to avoid distracting the user. However, many want the visual signal to still work, since it is easy to see from the corner of the eye without hearing the sound.
Xiaomi's Do Not Disturb mode settings have an exceptions section. You can add select contacts or recalls. If you add contact to exceptions, the phone may ignore the audio ban, but the flash behavior depends on the particular firmware version. In some cases, the hardware indicator continues to work regardless of the software constraints of silence mode.
To test for this behavior, turn on Do Not Disturb mode and ask someone to call you. If the flash doesn't work, try adding the caller to your favorites list or allowing notifications from the Phone app in the mode settings itself, which will keep visual visibility while remaining quiet.
⚠️ Warning: At night, a bright flash near the face can be unpleasant.Make sure the phone is on the screen down or away from the pillow if you leave visual notifications active at night.
💡
Do Not Disturb mode is more important than flash settings, so to make blinking work, you need to add a call to exceptions or allow notifications to the phone app in this mode.
Compatibility table and configuration options
Different Xiaomi, Redmi and POCO models may have different implementations of notifications. Below is a table that will help you navigate where to look for settings depending on your device type and shell version.
| Type of device/Shell | Location of settings | Features of work |
|---|---|---|
| MIUI 12/13 (Global) | Phone. → Settings → Incoming | Standard blinking, low flow rate |
| MIUI 14 / HyperOS | Settings → Sound and vibration | Possible integration with effects |
| Chinese version (CN) | Phone. → A gear. → Advanced Settings | Maximum functionality without bugs |
| The Redmi Go/Go Edition (Shot) | Third-party application required | System function is often cut down |
As you can see from the table, Chinese firmware owners often have more access to hidden features. If you have a global version and the feature is missing, sometimes changing the region in settings (Settings → Additional settings → Region) to India or China helps, although this can affect the operation of some local services.
It is also important to note that in the models with AMOLED-screens and the absence of a separate LED-The lights are the notification indicator (a small LED near the speaker), and the main flash of the camera takes over the indicator.
Troubleshooting and frequent errors
Despite the simplicity of the feature, users often face situations where the flash stops flashing or is not working correctly. One of the most common reasons is the aggressive MIUI energy saving system, which can kill the processes associated with notifications. To avoid this, find the Phone application or the flashing program you installed in the application list, go to the settings and select No restrictions for background activity.
Another problem may be the physical state of the flash module, where if the LED blinks dimly or flashes chaotically even in the camera, there may be a hardware malfunction or a power controller problem, in which case the software settings will not help, and you will need to diagnose in the service center.
☑️ Diagnostics of outbreak
And also, the trivial things to do: check if the camera's lens is covered with a cover or a finger. Some tight cases can block the light, making the blinking invisible. Take off the case and do a second test.
If nothing works, try resetting the Phone app to factory settings. Go to Settings → Apps → All Apps → Phone → Memory → Clean. This will return the standard call settings, and you can re-activate the flash function.
