How to turn off flash flash flash when calling on Xiaomi Redmi Note 4

Xiaomi’s Redmi Note 4 lineup has long been popular for its value for money, but its MIUI software contains many features that are not useful to all users. One of these options is light-based incoming calls, where the camera flash flashes rhythmically when a call arrives. For many device owners, this feature becomes a source of irritation, especially in the dark or during meetings, when sharp lights can distract others or attract unwanted attention.

Disabling this feature does not require superuser rights or complex system file interventions, as the developers have a regular mechanism for managing this parameter. In most cases, the problem is solved by simply switching the switch to the settings menu, but sometimes users face situations where the standard path does not work or the function is activated again after updating the firmware. Understanding how the notification system interacts with the hardware of the phone will help you effectively manage this process and avoid unnecessary inconvenience in the future.

In this guide, we will discuss in detail all possible ways to deactivate light signals on your device. We will not only look at the standard settings of the MIUI interface, but also touch on situations where you need to reset settings or check third-party applications. If you want to return your gadget to a calm mode without unnecessary light effects, carefully follow the instructions below to fully customize your Redmi Note 4.

Standard settings of the MIUI interface

The first and most obvious step to solve the problem is to check the basic parameters of the system, since this is where the switch is most often hidden. The MIUI interface installed on the Redmi Note 4 has a logical menu structure, but in different versions of the firmware, the names of items can vary slightly, which sometimes confuses inexperienced users. You need to open the main menu and find the Settings icon, which usually looks like a gear to begin the configuration process.

Once you log in, you should scroll down to the section that handles the additional features of the system. Depending on the shell version, this item may be called "Advanced Settings" or "Advanced", and it is inside that that that you have the light display control. Find the Light display bar and click on it to see the available LED and flash control options.

In the window that opens, you'll see several switches that are responsible for different types of events, such as missed calls, message notifications, and actually incoming calls. You need to find the Flash when you call and move the slider to an inactive position, after which the blinking should stop immediately. If this item is missing or inactive, this may indicate the specifics of your version of the firmware or conflict with other settings.

⚠️ Note: In some versions MIUI The “Run on a Call” setting can be hidden inside the “Mode in your pocket” item or only work when the screen is off, so check all adjacent sections.

It’s also worth noting that some global firmware versions for Redmi Note 4 can be put into a separate Themes or Security app that adjusts visual effects. If you don’t find the right switch in the standard settings menu, try using keywords in the top row of your settings search by typing “flash” or “indication.”

Setup via the Phone and Contacts app

If the global settings fail, the next logical step is to check the settings of the application itself, which is responsible for making and receiving calls. In the MIUI shell, the Phone application has its own set of settings that can overlap system settings or supplement them with specific functions. Open the standard “ringer” and pay attention to the three dots or menu icon in the upper or lower right corner of the screen.

In the dropdown list, select Settings, which will open the list of available options for managing calls. Here you should be interested in the section related to incoming calls, which can be called Inbound Calls or Answer and End. This section often hides the option Flash on incoming call, which controls the behavior of the LED module specifically during the call.

• 📞 Open the Phone app and go to the settings menu through three points.
• 🔍 Find the Incoming Calls or Call Settings section in the options list.
• 💡 Turn off the “Flash on a Call” or “Flash on a Flash” switch».
• 🔄 Restart the device to apply changes if the switch has been active.

It is important to understand that Redmi Note 4 can be installed different versions of dialer (callers): stock from Google or branded from MIUI. If you use a third-party application for calls downloaded from the Play Market, you need to look for a setting already inside it, since Xiaomi system settings may not apply to third-party software. In this case, go to the settings of the caller application itself and find the appropriate item there.

💡

If you use a third-party call (like Truecaller or Google Phone), look for flash settings within that app, not in the general smartphone settings.

Use of the "Do Not Disturb" mode

For those situations where you need to temporarily turn off not only flash blinking, but also audio signals, the Do Not Disturb mode is ideal.This Redmi Note 4 mode is designed to block all distractions, including visual effects, and can be activated both permanently and on schedule, activating this mode is guaranteed to turn off flash blinking as the system goes into silent and visual rest mode.

To activate this feature, lower the swipe notification curtain from top to bottom and find the crescent icon, which will turn on a mode in which notifications and calls will not be accompanied by light or audible signals, unless you add certain contacts to the exclusion list, which is especially convenient at night or during important meetings, when any flashing of the screen or flash is unacceptable.

A more subtle setup is available through the Settings menu → Sound and Vibration → Don’t Disturb. Here you can set up automatic switching on schedule, for example, from 23:00 to 07:00, which will save you from having to turn it on every evening.

Using Do Not Disturb is the most radical but effective way of ensure calm, but it blocks other notifications, which is worth remembering. If your goal is to remove only the flash blinking by leaving sound signals, this method may be redundant, and it is better to go back to setting specific call parameters.

Resetting the settings of the phone application

In cases where a software failure prevents flashing through standard switches, or settings are constantly reset, it may be necessary to clean the cache and data of the Phone application. This procedure will return the call application to factory state, removing all user configurations, including erroneous light display settings. It is worth remembering that the call history will not suffer, since it is stored in a separate contact database, but resetting the call settings can help.

To perform this operation, go to Settings → Apps → All apps and find the Phone app (or Calls) in the list. Select Memory, then click Clear or Reset, confirming your actions in the pop-up window. After that, the phone can restart and you will need to reset your preferred way of answering the call, but the blinking problem should disappear.

⚠️ Note: Resetting the Phone app can remove the forwarding and call wait settings, so make sure you remember your carrier codes or settings. SIP-accounts.

If the problem persists after resetting, try to also clear the Contacts system application data, since the two components in MIUI are closely related. Sometimes the conflict arises at the contact database level, which misinterprets the flash command for certain numbers or groups. Comprehensive data cleanup of both applications often solves mysterious software glitches.

Impact of Third-Party Apps and Themes

Often, the flash flash on Redmi Note 4 is caused by third-party apps installed by the user to enhance functionality or decorate the interface. Various launchers, design themes from the MIUI Themes store or specialized applications for managing calls can have their own priorities and force the flash to turn on, ignoring system settings. If you recently installed a new theme or application for calls, the problem is likely to lie in them.

Check the list of newly installed apps and try to remove those that have access to the camera or control notifications, especially the number detector apps that use the flash as a way to draw attention to the screen when an incoming call, disable or remove suspicious software and check if the blinking has disappeared.

• 🎨 Design themes: Some themes have built-in scripts for blinking, change the theme to the standard one.
• 📱 Caller apps: Third-party dialers can ignore system settings MIUI.
• 🔔 Notification Managers: Management Applications LED-indicator may conflict.
• 🛡️ Antivirus: Some security systems use flash to signal events.

It’s also worth checking the system’s Accessibility settings, as some hearing-impaired apps use flash as their primary method of notifying. If you have an app installed, go to its settings and turn off the visual alarm if you don’t need it. In MIUI, these settings are in Advanced Settings → Special Features.

Hardware features and diagnostics

You can not exclude the possibility of hardware malfunction or features of the particular instance of Redmi Note 4. In some cases, the flash LED can flash due to a short circuit in the control circuit or a software failure of the power controller, which mistakenly sends a signal to the camera module. If software methods do not help, and the flash flash even when turned off (if there is a charge) or chaotic, this can indicate a physical problem.

For diagnosis, try turning off your smartphone completely and leaving it for a while. If the flash continues to blink when it is off, it is almost guaranteed a hardware defect that requires intervention in the service center. However, if the blinking is only observed when the system is running, but is not disabled by any settings, you may need to flash the device or reset to factory settings (Hard Reset).

A unique feature of the Redmi Note 4: In some revisions of this smartphone, the flash LED and notification LED (if it is in this modification) can be physically combined into one module, which causes confusion in the settings.

If you decide to perform a complete data reset, be sure to back up all important information, as this process will remove all files from the internal drive.Switching to factory settings is often the last effective software method to deal with inexorable system bugs that affect peripheral devices like flash.

⚠️ Warning: If the flash flash flash flashes when the phone is turned off or heats up in the area of the camera without activity, contact the service immediately, as this may cause the battery to ignite or bloat.
