Xiaomi smartphone owners often face the need for visual notification of an incoming call, especially in noisy places or when the sound is turned off. the Redmi 6 model, equipped with a reliable MIUI shell, provides this opportunity, however, standard settings may not be obvious to the new user.
Android is connected to MIUI, and it has its own hardware features. Unlike some other manufacturers, there is no one universal button in the main menu that activates this feature for all scenarios at once. You need to consistently check several settings to make sure that the light indicator works correctly for phone calls, not just for instant messenger notifications.
In this article, we will discuss in detail all possible ways to activate this feature, we will look at the standard system tools, special access settings and possible reasons why the flash may not light up, and understanding these nuances will help you to customize the device as efficiently as possible for your needs.
Standard Activation through System Settings
The first and most obvious way to turn on the flash is to use the phone's basic settings. However, in MIUI, the path to this option may be different from the classic Android. You'll need to go to the settings menu and find the section that's responsible for the additional features of the device, which usually hides the switches associated with the hardware of the smartphone.
Find the option “Additional Settings” or “Advanced Settings” depending on the firmware version. Inside this section, you should look for a subsection related to special features or directly to notifications. This is where the flash button is located at notification, which is often turned off by default to save battery power.
It is worth noting that in some versions of the MIUI shell for the Redmi 6 model, this switch can only activate flashing for messages, ignoring incoming calls. So after turning on this option, be sure to check it by asking someone to call you. If the flash flash flash flashes, but only when the screen is locked, then the settings are correct, but have limitations.
⚠️ Warning: Activating a flash flash that flashes continuously can significantly increase your energy consumption.If you use your phone frequently in standby mode, monitor your battery level.
To make the settings more precise, you can search by settings, type the word "flash" or "indicator" into the main settings menu, and the system will suggest you go to the desired menu item, which will save you time searching in the confusing partition structure.
Use of the “Special Capabilities” section
If the standard path didn't work, you should go to the Features section, which is designed for people with disabilities, but is actively used by all users to expand the functionality, and this is where the deep hardware management settings, including the camera and flash, are located.
Go to Settings → Advanced Settings → Special Features. In the list that opens, look for the Hearings or Visuals tab. Depending on the regional version of the firmware, the desired switch may be called Flash at Notification or Mlight Notification. Activation of this slider force the camera LED to blink at any system event.
It's important to understand the difference between system notifications and calls. The feature section often takes precedence over the usual settings. If you've enabled the option here, it should work even when the phone is in Do Not Disturb mode, although this behavior may vary from the MIUI version.
☑️ Checking the settings of special capabilities
After the feature is enabled in the special features section, it is recommended to restart the device, which is necessary to ensure that the system services responsible for processing interrupts from the communication model correctly register the new status of the hardware indicator.
Configure via the "Phone" application
Special attention should be paid to the settings of the application itself for making calls. Xiaomi Redmi 6 uses a branded call from MIUI, which has its own rules for processing incoming connections, sometimes system settings are overlapped by local application parameters.
Open the Phone app and click on the gear icon or three dots in the corner of the screen to enter the menu. Select Settings or Additional. Here you should look for the Incoming Calls option. In some versions of the interface, this is the subsection where the switch is responsible for visual support of the call.
If you use a third-party app to make calls, like Google Phone, the path will be different, so you have to go to the settings of the Google app itself, select the Special Opportunities section already inside the app, and activate the feature, which is a common situation, as many users immediately change the standard call after purchase.
| Parameter | Standard MIUI call. | Google Phone |
|---|---|---|
| Location of the menu | Settings → Additional | Settings → Special Opportunities |
| Name of function | Flash on call | Flash on notification |
| Work in your pocket | Frequently blocked | Maybe it's working. |
| Dependence on the topic | Tall. | Low. |
Remember that using third-party themes may hide some menu items. If you can’t find the settings described above, try temporarily switching to a standard Classic or Default theme in the Themes app.
Problems with the operation of the flash in standby mode
Users often notice that the flash stops flashing when the smartphone screen is turned off and the device is in your pocket or bag.This is not always a system error.Redmi 6 has an approach sensor that can block camera and flash under certain conditions.
Energy saving also plays a major role: If the phone goes into deep sleep, it can turn off secondary functions, including LEDs, to extend battery life. Check battery settings: go to Settings → Battery and performance and make sure the phone app doesn't have a background activity limit.
⚠️ Warning: If the proximity sensor is contaminated or closed with a protective film, the system may mistakenly assume that the phone is near the ear and block the flash to avoid false positives.
There's a nuance to the screen modes, and if you have a "Rise to Wake" or "Double Touch to Turn on" feature on, it can conflict with flash blinking. Try turning off those functions temporarily to see if the indicator behavior changes.
Why does the flash flash flash but the screen doesn't light up?
Third-party applications for managing notifications
If Xiaomi's built-in tools fail to deliver the desired result, Google Play apps come to the rescue. There are many utilities, such as Flash Alerts or Call Flashlight, that take over the flash, run on top of the system and have more flexible settings.
When you install an app like this, you're going to have to give it a wide range of permissions, so it's going to ask for access to contacts, calls, and cameras, and without those permissions, it's not going to be able to track the incoming call and activate the LED, and be careful when you design it, so you don't want to install malware.
The advantage of third-party solutions is that you can set the flash modes, you can set the number of flashes, their duration and even color, if the phone model supports software color change of the LED (although Redmi 6 LED is usually single color), and such applications often know how to ignore calls from certain numbers.
💡
Use high-ranking apps with a lot of reviews. Avoid programs that require suspicious permissions, such as accessing an SMS or microphone without an explicit need.
But remember, third-party apps consume more resources, and they have to be constantly on the back of your memory, waiting for a call to be made, which can lead to a faster Redmi 6 discharge and extra ads if you use the free version of the software.
Diagnostics of hardware faults
In rare cases, the lack of flash response can indicate a physical breakdown. The LED in Redmi 6 is located next to the main camera. If it does not light up even when trying to take a photo with a flash, the problem lies deeper than the software settings.
For diagnosis, perform the following actions:
- 🔦 Open the Camera app and try to take a picture with the flash on.
- 📞 Use the engineering menu by entering the code ##6484## in the call and select the test. LED flashlight.
- 🔋 Make sure the battery is not critically low (less than 5%) as the system can block power-intensive functions.
If the test is successful in the engineering menu, and in normal mode the flash does not work when calling, then the hardware is working, and the problem is only in the software conflict or MIUI settings. In this case, resetting the phone to the factory settings can help, but this is an extreme measure.
⚠️ Warning: Before performing any tests in the engineering menu, make sure you understand the function function function. Changing unknown parameters can cause the device to function unstable.
It’s also worth checking if the phone has a magnetic cover or a case that covers the light sensor, and some accessories can cause interference that the system interprets as being in the dark or in your pocket, blocking the lights.
💡
If the test on the engineering menu shows the LED's performance, it's a software problem, and if the flash isn't burning anywhere, there's a possible hardware malfunction in the camera module or the plume.
