Disable flash when calling Xiaomi Redmi 9C

Many users of budget smartphones like the Redmi 9C experience unexpected device behavior during an incoming call. Instead of a standard display or vibration, the device starts flashing an LED flash aggressively. This can be annoying in the theater, at a meeting or at night, attracting unnecessary attention. Unfortunately, in the MIUI shell, this feature is often turned on by default and does not have an obvious off button in the standard call menu.

The problem is not hardware malfunction, but software availability settings. The system offers a notification flash option that activates for all incoming events, including calls. To stop using your phone as a strobe, you need to find a hidden switch in the depths of system settings. In this article, we will discuss the exact algorithm of actions that will help you restore calmness to your eyes and others.

It is worth noting that the menu layout may vary slightly depending on the firmware version installed on your Xiaomi Redmi 9C. However, the logic of the Android shell remains unchanged. We will look at the basic method through accessibility settings, which works in 99% of cases, and also touch on alternative options for specific versions of the software.

Reasons for the activation of the flash on the Redmi 9C

Before we start turning it off, it’s helpful to understand why it turned on at all. Xiaomi smartphones have a special section for people with hearing impairments, a feature called the notification flash, which is designed to visually signal an incoming event. However, system algorithms often treat any incoming call as a critical notification that requires attention.

Users often activate this option by accident, wandering through the settings menu to look for other features. Furthermore, after updating the MIUI firmware, availability settings can be reset to factory values, where this option is sometimes active, understanding the source of the problem helps not only eliminate it, but also prevent accidental activation in the future.

⚠️ Warning: A flash when ringing can significantly speed up battery discharge, as the LED consumes energy even in short pulses.

It is important to distinguish between system flash notifications and third-party app features. Some call programs downloaded from the Play Market may have their own display settings. If the system shutdown didn't work, it's worth checking the settings of the caller app itself that you use by default.

Step-by-step instruction through accessibility settings

The most reliable way to remove blinking is to use the built-in feature menu, which is standard and does not require additional software. You need to consistently follow the path that hides the desired switch. Be careful when switching toggles, so as not to activate other functions that change the behavior of the interface.

Follow the exact action algorithm below. Redmi 9C interface is logical, but item names can be written in fine print. Make sure the screen is unlocked and you're on the home screen.

To start, open the main settings menu of your device. Usually, the icon looks like a gear. Scroll down to the section called Additional Settings or simply Advanced, and that's where the tools to fine-tune the system are hidden.

In the list that opens, look for Special Opportunities. Some versions of MIUI may call it Accessibility. Inside this menu, you're interested in the tab at the top of the screen. Often the default tab is "Hearing," but we need the next one, Vision or Visual.

Once you switch to the visual settings tab, you'll see a list of options. Find the Notification Flash bar. Next to it will be an active switch. Click on it to turn gray (inactive). Now the camera will stop blinking when the call is in.

💡

If you can't find "Notification Flash," search inside the settings. Type the word "flash" into the search bar at the top of the settings menu, and the system will redirect you to the desired switch.

Adjusting the behavior of the application Phone

Sometimes the system availability setting is disabled, but the call still causes a light indication. This can happen if the settings are applied only to a particular Phone application. In the MIUI shell, each application can have its own permissions and behaviors.

Check the settings of the app itself, which you make and receive calls through. The standard app is called the Phone (green handset icon), and go to its settings by clicking on three dots or a gear inside the call interface.

Inside the menu, find Incoming Calls. You can have vibration and sound settings. Make sure there's no flash check box. If there's no flash check, go back to the general settings and check if the Phone app has permission to use the flashlight in the background.

Also worth paying attention to is the design theme: some MIUI themes downloaded from the official store may force flash as part of the visual style, and if the problem comes after the theme change, try to bring back the standard design.

Use of the "Do Not Disturb" mode

If you need to temporarily turn off all light and sound signals, such as during a sleep or an important meeting, the best way to use Do Not Disturb mode is to block not only calls, but also flash flashing, even if it is enabled in the availability settings.

You can activate this mode through the notification curtain. Swipe down from top to top to open the control center, and find the crescent icon. Pressing it will turn on silence mode. In this state, the Redmi 9C will not respond with light to incoming events.

You can set the schedule for this mode to turn on automatically at a given time. Go to Settings → Sound and vibration → Do not disturb. You can set the start and end times, and also choose which contacts can reach you even in silence.

Therefore, it is recommended to add selected contacts to the exclusion list, which will allow loved ones to contact you in an emergency situation without disrupting the general silence mode of the device.

Solving problems with third-party applications

It's not uncommon for the system to blink, but for the programs you installed. Messengers like WhatsApp, Viber, or Telegram can use the flash to notify you of messages that the user confuses with a call. There are also bell-ringing apps that replace the standard interface.

Check the notification settings in each of the messengers. Go to Settings → Notifications inside the application itself and find the item associated with the light indication or LED. Turn it off for all chats or only for important dialogues.

If you have installed a third-party caller from the Play Market, it may have its own access rights to the hardware phone. In the settings of such an application, look for the Call Flash or Caller ID sections. Often there is a Flash on call feature that you need to deactivate.

⚠️ Note: Third-party applications may request permission to use the camera and flashlight. Read the requests carefully when installing new software.

For diagnostics, try running your phone in safe mode, and if it doesn't flash when you call, it means that one of the apps installed is to blame, and delete the newly installed programs one by one, checking the result.

Resetting and system update

In rare cases, the problem can be caused by a software failure in the MIUI configuration files. If none of the above methods worked, you should try resetting special features. This will not delete your personal data, photos or contacts, but return the system switches to their original state.

To do this, go to Settings → Advanced Settings → Special Features. At the bottom of the screen or in the menu (three dots), find Reset. Confirm the action. Then check if the flash is gone. If it reappears immediately after the reset, then the problem is deeper.

Also make sure your Redmi 9C has the latest firmware installed. Xiaomi regularly releases updates to fix interface bugs. Go to Settings → About phone and click on the MIUI logo to check for updates.

💡

If nothing works, perform a full Factory Reset, saving a backup of the data beforehand, and this is guaranteed to eliminate software conflicts.
