How to remove flashlight flicker when calling Xiaomi Redmi: a step-by-step solution

Xiaomi and Redmi smartphone owners often experience an intrusive visual effect, where a flash or indicator flashes randomly during a conversation or while waiting for a call. This phenomenon, known as flashlight flickering when calling, can be very annoying, especially in the dark or during a business meeting.

The reason for this behavior of the gadget lies in the features of the shell MIUI or HyperOS, where the functions of the call notification and flashlight sometimes conflict with each other. Most often, users confuse the work of the standard notification indicator (Notification Light) with the software management of the main flash. It is important to immediately understand what is flashing in your case, since the methods of elimination will differ.

In this guide, we’ll look at all possible scenarios, from call settings to firmware system bugs, how to deactivate notification flash, reconfigure the phone module, and what to do if a problem is caused by third-party software. Follow the instructions carefully to return the comfort of your Xiaomi Redmi.

Differences between Notification Indicator and Flash

Before you start settings, you need to clearly identify the light source. Modern smartphones Xiaomi and Redmi often lack a separate LED indicator, and its role is played by the screen or the main flash of the camera. If the top corner of the screen or the area of the speakers flashes, this is a software simulation of the indicator.

If a bright white or yellow light light is lit next to the camera, the flash function is activated when notifying. On Android, this feature can be duplicated: one setting is responsible for flashing in standby mode, another during an incoming call. Confusion occurs when a user turns off one option but forgets about the second.

It is also worth considering that some models of the budget segment use a screen flash (the screen lights up with a certain color) instead of a screen flash. LED-In these cases, the flickering looks like the pulsation of the backlight of the display, even when the phone is down, an important nuance for owners of the Redmi Note and Redmi A series.

Disabling the notification flash in the system settings

The most common way to remove flickering is through the system settings menu. In the MIUI shell, the path to this feature may vary slightly depending on the Android version, but the logic remains the same. You need to find the section responsible for special features or additional interface settings.

Go to the main menu and select Settings. Next, scroll down to Additional Features or Advanced Settings. This is where the switch lurks, which causes the flashlight to flash when a call or message arrives. Find the option "Flash at Notifications" and put the slider in an inactive position.

If you don't have a switch at that location, search by settings. Type the word "flash" or "notification" into the search box. The system will provide the right shortcut. On some versions of HyperOS, this feature has moved to the Sound and Vibration menu -> Additional.

When you change the settings, you should make a test call. Note that the changes are effective instantly, you don't need to restart the device. If the flicker stops, then the problem was the software setup of the interface.

Setup of the phone application and call mode

Sometimes the system settings don't override the settings of the Phone app itself. Xiaomi's built-in software has its own set of features that can activate flashlight flickering when you call, regardless of the system's global settings, and this is done to attract attention in noisy places.

Open the Phone app and click on the three dots in the top right corner (or menu button). Select Settings. In the settings list, look for Call Mode or Incoming Calls. This may be "Blink Flash" or "Visual Effects."

Newer versions of MIUI have introduced a Motion Response or Ear Raising feature that can also trigger sensors and flashes, and try temporarily disabling these features to eliminate their impact on the indicator, which is especially true for models with an IR port where sensors are located next to the flash.

⚠️ Note: If you use a third-party call (such as Google Phone or Truecaller), the settings of the built-in application will not work.

The Impact of Third-Party Applications and Conflicts

Often, the reason that the flashlight on Xiaomi begins to behave unpredictable, are third-party applications, such as smart flashlights, number-detection applications, memory cliners, or even games with permissions to access the camera. LED-module.

Analyze which app you found the problem with. If you've been running a Turbo flashlight or similar utility, delete it. Many of these programs have background services that conflict with system call management. Also check ringtone-making apps, some of which add visuals.

To diagnose, run your phone in Safe Mode, which is only system applications, and if you're missing a flicker in Safe Mode, it's one of the apps you've installed that's to blame, and delete them one by one, check the results after each deletion.

Reset network settings and special features

If simple switches didn't help, there may have been a software glitch in the communication module or in the special features profile. Android has hidden settings that can force a flash for people with hearing impairments.

Go to Settings -> Advanced Settings -> Special Options. Go through the Vision and Hearing tabs. Make sure that Flash At Notifications or Audiovisual Alarms are not activated anywhere. Even if the slider is off, try switching it back and forth.

Also effective is resetting network settings. This won't delete your personal data, but will return Bluetooth, Wi-Fi and mobile settings to factory values. Path to function: Settings -> Connection and Sharing -> Reset Wi-Fi, mobile networks and Bluetooth.

💡

Before resetting your network settings, write down passwords from important Wi-Fi networks, as they will have to be re-entered.

Hardware problems and short circuit

And if the flashlight flickers randomly, not only when the bells are ringing, but also when the upper body is heated, the problem may be iron, and a common cause is moisture entering the camera plume or contact oxidation.

Moisture can create microcircuiting, which the system perceives as a signal to turn on the flash. Even if the phone is supposedly waterproof, over time the leakage is broken, in such cases, the software methods are powerless - it requires disassembling and cleaning the board or replacing the plume.

It's also worth checking if the main camera plume has moved away, and if you fall, the contact may be disrupted, and the flash module will start to work incorrectly, receiving erroneous signals from the power controller, and if the phone has recently fallen, the likelihood of this cause increases.

⚠️ Note: If flickering is accompanied by a rapid battery discharge (for example, 20% per hour in standby mode), immediately contact the service.

Radical measures: complete reset and reflashing

When none of the methods worked, the last software option is a full reset to factory settings (Hard Reset), which will delete all data, so be sure to back up contacts, photos and documents to the Mi Cloud cloud or your computer.

To perform the reset, go to Settings -> About Phone -> Settings Reset -> Erase all data. Once the phone is rebooted, it will look like new. If the flicker is left even on a clean system with no installed applications, it is 99% hardware problem.

In rare cases, flashing the device through a computer using the Mi Flash Tool utility helps. However, if the problem is hardware in nature, flashing only temporarily hides the symptoms or does not give any effect. If after a complete reset, the flashlight continues to flash when calling without installed applications, a diagnosis is necessary at the service center.

💡

If after a complete reset the problem persists, further software manipulation is useless - hardware repair is required.
