Many Xiaomi smartphone users who are switching from other brands or simply want to expand the functionality of their device often face the lack of obvious system settings. In particular, the question of how to make the camera blink when an incoming call or message remains one of the most popular in the MIUI owners’ communities. The standard HyperOS shell and earlier versions of MIUI do hide this option in non-obvious places, and in some regions it can be completely disabled by the manufacturer by default.
Activating a light signal is not just an aesthetic decoration, but also a useful accessibility feature, which allows you to notice a missed call, even if the phone is lying down on the screen or in your pocket (provided the latter is transparent). LED-The indicator worked correctly, you need to take into account a number of software limitations and features of the power management system. In this article, we will discuss in detail all available activation methods, including hidden menus and third-party software.
It should be noted that the presence of a hardware flash does not guarantee its operation as a notification indicator at the software level. Different models of Redmi and Poco may have differences in the camera drivers, so there is no universal switch “on everywhere”.
Built-in settings for MIUI and HyperOS
The first thing to start looking for a cherished feature is the phone's standard settings menu. Xiaomi engineers periodically change the location of items, but the logic remains the same: the feature is hidden in the special features section. This is done to avoid overloading the interface with unnecessary switches for those who don't need this option, and you can find it by going down the Settings path. → Advanced settings → Special facilities.
Inside the special features section, the interface may vary depending on the shell version. You need to find a tab that is usually called "Vision" or "Hearing", although in new versions of HyperOS, the menu structure has been redesigned. Look for "Flash at Notifications" or "Flash Notification". If the switch is active, the system will briefly turn on the camera LED when the signal arrives.
⚠️ Note: Some global firmware versions (Global) ROM) This item may not be physically present even if it is in the Chinese version (China). ROM) This is due to regional certification restrictions.
If you find a switch that is inactive (gray), check whether the power saving mode is on or Quiet Mode. The system can block the flash to save battery power. Also make sure you do not activate the Do Not Disturb feature, which often takes precedence over visual notifications. Turning on the light signal in normal mode is the most stable option, not requiring the installation of excess software.
Use of the Camera application to activate
There is a lesser-known activation method that works on a number of models through the Camera app itself. It's a kind of hidden flag that sometimes persists even after a reboot, although it's not a permanent solution. To try this method, open the camera app and go to settings (icon or gears).
In the list of options, scroll down to the end. Some people say they're successful in activating "Flash on Notification" if it's available in your version of the app. But most often, this method requires you to do something like open the camera, turn on the flash, turn on the app, and check the notifications. It's more of a bug than a feature, but on older Redmi Note models, it sometimes works.
💡
If the standard camera doesn’t give you access to flash settings, try installing Google Camera (GCam) – some builds have a separate module to control. LED-notice.
A more reliable option in system applications is to use Task Manager or built-in optimizer. Go to the Security app (green lightning icon), select Notifications and check permissions for system services. Sometimes, banning the background operation of the notification service blocks access to the flash hardware.
Third-party flash management applications
When the built-in means activate LED-The indication fails, and Google Play apps come to the rescue, and the market is full of utilities that take over the control of incoming events and force the flashlight on. The most popular and time-tested are Flash Alerts, Blink Call Flash, and the most popular"LED Flash for Alerts".
The way these programs work is simple: they hang in the background, they monitor the call and message log, and when a new event happens, they send a command to turn on the flash. But this method has its own nuances. First, they require permanent permissions to access contacts, phone and SMS. Second, they can conflict with the aggressive MIUI energy saving system, which will try to "kill" the process in the background.
- 📱 Flash Alerts 2 is a classic solution with flexible blinking frequency settings and a selection of applications that need a flash.
- 🔔 Blink Call Flash is a minimalist application that consumes almost no battery and has a simple interface without ads.
- 💡 LED Flash for Alerts is a powerful tool that allows you to customize different colors (if hardware allows) and blinking patterns for different contacts.
When installing third-party software, be sure to add it to the battery exception list. Go to Settings → Apps → All Apps → [Application Name] → Battery and select "No Limits." Without this step, Xiaomi will turn off the program 15-20 minutes after the screen is turned off, and the flash will stop lighting up.

Comparison of Indicator Activation Methods
To make it easier for you to choose the right option, we have prepared a comparison table that will help you assess the pros and cons of each method, taking into account your priorities: stability, battery consumption or the availability of additional features.
| Method | Stability | Battery consumption | Difficulty setting up | Dependence on software |
|---|---|---|---|---|
| System setup | Tall. | Minimum | Low. | Depends on the region. |
| Apps from Play | Medium | Medium. | Medium | It doesn't matter. |
| Hidden codes | Low. | Minimum | Tall. | Depends on the model. |
| Root rights | Maximum | Minimum | Very high. | Full control. |
As you can see from the table, system configuration is the most preferred option if it is available on your device, it does not require additional code, it does not hang in RAM and does not ask for unnecessary permissions, but if you own a rare model or a specific version of firmware, you will have to resort to installing third-party utilities.
⚠️ Note: Using applications that require Root rights may result in loss of warranty and inability to operate banking applications (Google Pay, Mir Pay) without additional disguise.
Solving energy conservation problems
The most common reason a flash stops working or is unstable is Xiaomi’s aggressive power saving mode, which can find the background service responsible for blinking harmful or simply unnecessary and turn it off, and to avoid this, manual optimization is necessary.
Go to the Security app and select Battery, and find the mode and switch it to Performance for at least a temporary check. You can fine-tune it through the app menu by finding the program that manages the flash (or the system notification service) in the list and not autostart it only when the system starts, but allow background activity.
Secret code to check LEDs
It's also worth checking the Advanced Energy Saving settings. If this mode is on, it blocks all background processes, including flashlight blinking. Turn it off if you want to use your phone to its full potential. Remember, the flash running in the background still increases charge consumption, albeit marginally.
Setup for different applications (WhatsApp, Telegram, Viber)
Special attention should be paid to setting up flashes for specific instant messengers, which often happens that the phone flashes on calls and does not blink on messages from WhatsApp or Telegram, because system settings often cover only standard SMS and calls.
To set up third-party apps, you can use the functionality of the messengers themselves or specialized utilities. For example, Telegram has a built-in but hidden function: Settings → Notifications and Sounds → Light indicator. WhatsApp has a similar path: Settings → Notifications → Light. Make sure the ticks are set there.
If the messaging settings are not working (which is common on Android 11/12/13/14 due to security limitations), use a proxy app like "Notify for Android." It can intercept notifications from any application and convert them into flash, vibration or sound signals. It is a powerful tool for advanced users to create unique blinking patterns for each contact.
💡
For stable operation of notifications from messengers, it is critically important to allow them to auto-start and work in the background in the MIUI battery settings.
