How to turn on a flashlight when calling on Android Xiaomi

Modern Xiaomi and Redmi smartphones have a huge number of hidden features that often go unnoticed by users, one of which is the flash of the camera during an incoming call. This feature is especially relevant for people with hearing impairments or those who are often in noisy places where you simply can not hear the melody of the call. MIUI.

Device owners often look for ways to personalize their gadget, making it more convenient in everyday use. Turning on a light signal is a simple step that can significantly improve the comfort of using a phone. In this article, we will take a detailed look at all available methods for activating a flash, look at the nuances of different versions of the operating system and answer frequently asked questions.

Why do you need a flash on an incoming call?

The light signal feature was introduced by Android developers for a reason, primarily to help hearing-impaired people by visually tracking incoming connections, but the range of applications is much wider than it seems, and many users find it useful in situations where the phone is lying down screen or in a bag where the sound can be muted.

In addition, in emergency situations, when the smartphone battery is discharged and the device goes into power saving mode, the audio signals can be turned off by the system to save charge, while the flash consumes minimal amount of energy and is able to notify the owner of an important call even at a critically low battery level, which makes the function not only convenient, but also practical.

⚠️ Attention, the constant use of flash when calling can cause the camera module to heat up in the area of the speaker.

It’s worth noting that implementations of this feature may vary depending on the firmware version. On global versions of MIUI, settings may be in one place, and on Chinese builds or HyperOS, in another. Understanding the logic of the system will help you find the right switch in the menu of your particular device faster.

Standard way to activate via phone settings

The easiest and most reliable way to turn on a light signal is to use a built-in call settings menu, which works on most current Xiaomi, Redmi and POCO models, and you need to unlock the device screen and go to the main application menu first.

Find the standard Phone app, which usually has a green or blue phone icon, and it controls all the parameters of incoming and outgoing calls. After you run the app, look at the interface: there should be a three-dot or gear button in the upper right or lower corner of the screen that indicates the menu.

When you click on this button, you'll see a drop-down list where you want to select Settings, and the menu that opens will show you a long list of options, like locking numbers, redirecting, and others, and you'll need to find a section called Incoming Calls or Call Settings, and inside that section, you'll find the switch you're looking for.

Look for an option called "Flash on a Call" or "Flash on a Flash." Activate the slider opposite this line. Once turned on, the system can request permission to use the camera for this feature -- be sure to agree with this request, otherwise the mechanism will not work. Now, when an incoming call arrives, the LED flash will rhythmically blink.

Configure through the menu of special features

If you don't find the right switch in the standard call menu, don't worry. In newer versions of the MIUI and HyperOS shell, developers often move accessibility-related features to a separate part of the system, a method that is universal for all Android smartphones 10 and higher.

To access these settings, open the main Settings menu of your smartphone. In the list of general options, find the Advanced Settings or Advanced. In some builds, this item may simply be called Special Opportunities. Going inside, you will be taken to a menu designed to adapt the interface to the user's needs.

You'll need to find a subsection called "Hearing" or "Hearing." This is where you find functions that replace or duplicate audio with visual signals. Find "Notification flash" or "Call flash." Unlike phone settings, you can more flexibly control the behavior of the indicator.

This menu often provides additional settings for different types of events, so you can choose whether the flash will only flash when you call, or whether it should respond to the flash as well. SMS-This allows you to create a single light alert system for all important events.

Use of third-party applications for customization

Xiaomi’s built-in functionality may seem limited to users who want to see not just flashing, but complex light effects or color indications for different contacts. The standard system allows you to only turn on or off the flash, without giving control over the frequency of blinking or pulse duration.

To expand the capabilities, you can use apps from the Google Play store. There are many programs, like Flash Alerts or Call Flashlight, that take control of the LED, and these apps run on top of the standard call system and intercept the incoming call event.

Once you install an app, you're going to have to give it a number of permissions, usually access to contacts, a phone, and of course a camera, and without those permissions, it won't be able to detect the time of the call and turn on the flashlight, and it's important to download those tools only from trusted developers to avoid leaking personal data.

⚠️ Attention! Third-party applications may conflict with the system flash function. If the standard flash stops working after installing the program, delete the application or disable it in the battery settings.

The advantage of third-party solutions is that you can create profiles, so you can set up a flash from close relatives to flash quickly and brightly, and from unknown numbers to flash slowly and dimly, which adds another layer of personalization to your device, making it truly unique.

Comparison of flash-inclusion methods

The choice of the method of activating the light signal depends on your goals and the model of the smartphone, so to make it easier for you to decide which method is suitable for your case, we have prepared a comparative table of the main characteristics.

As you can see from the table, embedded methods benefit in terms of optimization and power consumption. They are deeply integrated into the system and do not create unnecessary load on the processor. Third-party applications are only advisable if you really do not have enough standard functionality to implement specific use cases.

It is also worth noting that on some budget models Redmi without NFC-The flash module may be the only light indicator, in which case its operation when the bell is called becomes critical to navigating the status of the device. In flagship models, there is often a separate notification LED that can duplicate the flash function.

Possible problems and ways to solve them

Despite the ease of setting, users may encounter situations where the flash stops flashing or is not working properly, most often the problem lies in the aggressive MIUI energy saving system, which limits the background operation of processes, including controlling the camera during the call.

To solve this problem, you need to go to the battery settings and find the Phone or System Calls app. From the energy saving menu, select No Limits mode, which allows the system to freely use flash resources even when the screen is off or the phone is in your pocket.

Another common reason is the use of cases. Dense protective cases, especially those with metal edging or thick walls in the area of the camera, can block light or cause overheating. If you notice that the phone is very warm in the area of the camera module after the call, try removing the case and check the function again.

💡

Use Do Not Disturb mode with exceptions so that the flash only works for selected contacts, saving battery life the rest of the time.

In rare cases, you may need to reset your network settings or even completely reset your device to factory settings. However, before such drastic measures, it is recommended to simply restart your smartphone. Often a simple system restart eliminates temporary software failures that interfere with the correct operation of the camera drivers.
