The flash feature is one of the most popular options in Xiaomi smartphones, which allows you to avoid missing an important call even in noisy environment. Owners of the Xiaomi Redmi 7 model often find that the standard settings menu is not always obvious, and some functions are hidden in the depths of the system partitions. In this article, we will discuss in detail how to activate flashing flashlights during an incoming call using the standard means of the MIUI shell.
It should be understood that LED-The flash in this model is not only a lighting fixture, but also an effective visual indicator, and the proper setting of this feature saves battery power compared to a constantly burning screen and provides better visibility in the dark. We will look at both basic activation methods and more advanced methods through the engineering menu and third-party software.
Before you make any changes, make sure your device is running correctly and has the latest firmware installed. Sometimes the lack of the right switches is due to software failures that can be easily fixed by restarting or updating the system. Next, we will move on to directly configuring notifications and calls.
Standard Call Settings in MIUI
You can start with the native Phone app, which is pre-installed on the Xiaomi Redmi 7. This is where the basic incoming connection processing options are hidden. Open the app and find the gear icon or three dots in the top right corner of the screen to get into the call settings menu.
In the list that opens, look for the section related to incoming calls. Depending on the version of the MIUI shell, this item can be called differently, for example, "Additional settings" or simply "Call settings." Inside this menu should be a switch responsible for the operation of the LED indicator.
If you don't find the right switch right away, try searching by settings, type the word "flash" or "light" into the search box, and the system will tell you where the desired option is, which greatly speeds up the process of configuring notifications.
In some cases, the standard function may be called “Blinking on a Call” or «LED-It is important to activate this particular parameter so that the camera or individual LED flashes when the signal arrives.

In the standard MIUI menu, the option can be hidden if Do Not Disturb or energy saving is enabled.
Use of the Engineering Menu to Activate
For more experienced users who do not find the right option in the regular menu, there is access to hidden settings through the engineering menu, this method allows you to control the hardware components directly, including LED control. Be careful when changing the settings in this section, as incorrect settings can affect the stability of the system.
To get into the engineering menu on Xiaomi Redmi 7, you need to open the Phone app and dial a special combination of numbers. Once you enter the code, the device will automatically go to testing mode, where various hardware checks are available.
Codes for entering the engineering menu
In the test menu, select the LED or LED option, where you can check the flash performance and, in some firmware versions, force the flash mode to be activated when you call. If there is no LED option, try looking for the Hardware Testing section.
Using an engineering menu is a powerful tool, but it requires caution: Don't change values that you're not sure about, especially those that concern a radio module or processor frequencies. Your goal is just to check and activate the light indicator.

Before entering the engineering menu, take a screenshot of the current settings to be able to return everything as it was in the event of an error.
Configuring through third-party applications
If the built-in MIUI tools don’t provide enough functionality or an option is missing from your firmware version, Google Play apps come to the rescue. There are many programs specifically designed to manage the flash when calling and notifications on Android.
One of the most popular solutions is Flash Alerts, which intercepts an incoming call signal and causes the flashlight to flash at a given frequency, and these programs often have more flexible settings than standard system tools.
| Annex | Functional | Resource consumption |
|---|---|---|
| Flash Alerts 2 | Blinking on call/SMS | Low. |
| Call Flashlight | Pattern adjustment | Average. |
| LED Flashlight Alerts | Working in the background | Low. |
When installing third-party software, pay attention to the permissions you request, the software needs access to the camera, contacts and phone to work properly, and without these permissions, the application will not be able to respond to incoming events.
Some apps may conflict with Xiaomi's energy-saving features. To avoid this, add the program to battery exclusions and allow it to auto-start. This ensures that the flashlight works even if the application has been unloaded from memory.

Solving Access and Permits Issues
A common cause of a broken flash when calling Xiaomi Redmi 7 is the strict security settings of the MIUI shell. The system can block the background work of applications that try to control the LED, considering them to be consuming the battery.
To fix this problem, go to your phone's settings and find the Apps section. Select the flash app you installed or the standard Phone and go to Permissions. Make sure that access to the camera and other necessary features is allowed.
⚠️ Attention: B MIUI There's a separate auto-start menu, and if a flash app isn't added to the list of auto-starts, it won't work when the phone is in sleep mode.
Also worth checking is the energy saving settings, select No Limits mode for the LED control application, which will prevent the system from forced closure when there is a shortage of free RAM.
If the function still doesn't work after all the settings, try clearing the phone app cache or reinstalling a third-party program. Sometimes it helps to simply reset the date and time settings to automatic ones, since desynchronization can affect the task scheduler.
Impact of energy saving regime on outbreak
Power saving mode is a dual tool in Xiaomi smartphones, on the one hand, it prolongs the life of the battery, on the other hand, it can turn off energy-intensive functions, which include the use of a battery. LED-flash.
When the Saving Energy mode is activated, the system limits the background activity and brightness of the screen, and in some configurations this restriction extends to the frequency of flashing the indicator or completely turns it off when an incoming call is made.
How the ultra-saving regime works
To check if this mode is affecting your problem, temporarily turn off the power saving and make a test call. If the flash is triggered, then you need to add exceptions for the call service to the battery settings.
Redmi 7 users are encouraged to use standard mode or Performance mode during important call expectations to be sure all visual notifications are working.
