Modern smartphones rarely feature the familiar LED lights that lit up at the top of the case, signaling missed calls. Owners of Xiaomi, Redmi and POCO devices often wonder how to make a flash camera act as such a alert, a feature that is not only aesthetically pleasing, but also extremely useful in situations where the phone is lying down screen or in a noisy room.
Activating this option requires understanding the differences between system notifications and third-party applications. Depending on the version of the MIUI shell or the new HyperOS, the algorithm of actions may vary slightly. We will consider all current methods, including hidden settings and third-party software that is guaranteed to work.
It’s worth noting that standard Android features allow you to flexibly adjust flash behavior, but manufacturers often hide these settings or change their location to favor minimalist interfaces. Below is a detailed guide to help you avoid missing any important call.
Standard Activation through System Settings
The easiest way to make a flash flash flash flash when an incoming call is to use the built-in functionality of the system. In most current versions of Xiaomi shells, this option is available by default, but you need to find it. It is usually hidden in the section responsible for additional features of the device.
To start, you need to open the main settings menu. Scroll down to Advanced Settings or Additional Features. This is where tools that aren't critical to basic work but improve user experience are hidden. In some firmware, this section may be called Special Opportunities.
Inside the menu, find the item "Flash at notifications" or "Call notification." Once the slider is activated, the phone will start using the device. LED-It's important to understand that in standard mode, the flash can flash not only when you call, but also when you receive messages.
Setting up a flash for specific applications
System settings don’t always allow you to flexibly manage which apps can use the flash, and users often only want to see blinks when calling from certain contacts or messengers like Telegram or WhatsApp, which requires a deeper setup.
In the Notifications and Status bar section, you can find the indicator management options, and you should be careful here, because the menu can be overloaded with unnecessary information. LED-It's the pointer or the lights. This is where the priority of the applications is set.
- 📱 Open “Settings” and go to “Notifications and Status Bar».
- 🔍 Find the item "Notification Indicator" or "Light Indicator».
- ⚙️ Select the desired application from the list and enable the use of flash for it.
- 🔔 Check if the flash switch is activated».
Some versions of MIUI have a bug where settings are reset after rebooting. If you encounter such a problem, try turning off the phone after you turn on the feature and turning it on again to check if you save the settings.
💡
If the standard switch doesn’t work, try resetting your phone’s app settings through the Apps menu → All Apps → Phone → Clear → All Data.
Using third-party applications for blinking
If the built-in tools fail to achieve the desired result, third-party developments will come to the rescue. Google Play offers a variety of utilities that take control of the flash, which often have more functionality than the standard system.
One of the most popular solutions is Flash on Call, which allows you to set your flash modes, select colors (if you have a multi-LED flash), and schedule your work, and installing this software is a great solution for older models where system functions are limited.
| Annex | Type of license | Key feature | Impact on the battery |
|---|---|---|---|
| Flash on Call | Freemium | Flexible pattern setting | Average. |
| LED Flash Alerts | Free of charge. | Working in the background without lag | Low. |
| Notification Flash | Paid. | Integration with contacts | High. |
When installing third-party software, be sure to give it all the permissions you ask for. Without access to the camera and notifications, the app will not be able to function properly, and it is also worth checking the energy saving settings so that the system does not “kill” the process in the background.
Why can third-party applications drain the battery?
Features of work in the mode “Do not disturb”
Do Not Disturb (DND) mode is designed to be quiet, but visual cues may be needed even in this case, such as you can sleep but want to see a flash flash flash if your favorite contacts are calling, and setting up this scenario requires special attention.
There are exceptions to the standard Do Not Disturb menu: You can allow calls from Favorites or re-calls. However, visual displays are often turned off globally, and to get around this, you need to create an exception for the Phone or Contacts app itself in the notification settings.
⚠️ Warning: In Do Not Disturb mode, the flash may not flash if the screen is off and the phone is lying on a hard surface, as some proximity sensors block camera activation to save energy.
Check your Important Notifications settings. Android has a concept of priority notifications that break through any locks, and if you assign a contact Important status, the likelihood of a flash trigger increases significantly even with active restrictions.
Solving flash flash flash problems
There are times when all the settings are right, but the flash persists in blinking, and most often the problem is a conflict of software or hardware constraints, and the first thing to do is check if the flash is not occupied by another process, such as a flashlight or a camera.
Also, the cause may be overheating of the device. Xiaomi's protection system can block work LED-If the body temperature is above the normal limits, let the phone cool down and try calling it again.
☑️ Diagnosis of outbreak failure
If the flash flash flashes randomly or only once, it may be the camera drivers. Try updating system components through the Security app or the GetApps store. Sometimes resetting the network settings that restarts communication modules helps.
Impact of energy saving on the indicator
Aggressive battery optimization is a scourge of modern smartphones, and the system can turn off background processes that monitor incoming events to keep the battery charged, especially for models with large screens and powerful processors.
To keep the flash running smoothly, add the apps you use (call, messengers) to your power saving exception list. The path usually looks like: Settings → Battery and Performance → Application Activity Control. You need to set the No Limit mode here.
💡
The stable operation of the flash depends on whether the application is allowed to operate in the background without power consumption restrictions.
Remember, the constant operation of the flash as an indicator is itself energy-consuming. LED-The elements consume little, frequent notifications can significantly reduce battery life by the end of the day.
Specifics of settings on different versions of MIUI and HyperOS
Xiaomi’s shells are constantly updated, and the menu layout changes. On MIUI 12 and 13, the settings are often in the “Advanced” section. In newer versions like MIUI 14 and HyperOS, the logic has changed towards grouping functions by purpose.
HyperOS has Light Effects, which combines flash management for calls and notifications, and it's more graphical, allowing you to choose not just the blinking, but the intensity of the blinking, which makes the setting more intuitive, but hides advanced options.
If you upgrade to a new version of the software and you lose your old settings, don't panic. They probably just moved. Use a setting search to type in the words flash, blink, or light. This is the fastest way to find the right switchboard in a confusing menu.
