A camera flash that lights up in a pocket or in the dark when an incoming call comes in often becomes a source of irritation or awkward situations. This feature, while intended to be a useful indicator for hard-of-hearing users or noisy environments, may actually drain the battery and attract unnecessary attention. Fortunately, the operating system Android provides several ways to control this parameter, although the ways to activate them may vary significantly.
Before proceeding with the settings, it is worth noting that the location of icons and the names of menu items directly depend on the version of the operating system and the shell installed by the manufacturer. For example, on pure Android from Google the logic will be the same, but on OneUI from Samsung or MIUI from Xiaomi it will be completely different. Universal button it does not exist for all devices, so the user will most likely have to adapt general recommendations to their specific gadget.
In some cases, it will not be possible to turn off blinking using standard system tools if the manufacturer has hardcoded this function into the basic notification profile. Then third-party applications or deeper settings through the engineering menu come to the rescue, which we will also talk about. The main thing is not to panic if you don’t find the right switch on the first try, since the system for protecting against accidental changes often hides such options.
Standard Android system settings
The most logical place to find the right switch is the standard phone settings menu. In most modern models, the path to controlling the indicator lights is hidden in the accessibility or accessibility section. This is because flash flashing was originally created as an assistive function for people with hearing impairments. To find this section, you need to open Settings and use the menu search or manually scroll down the list.
After entering the menu Special features (or Accessibility), you should look for a subsection related to hearing or physical features. Depending on the model of your smartphone, the item may be called “Improving hearing”, “Hearing aids” or simply “Flash on notification”. This is where main software switchis located, which controls the blinking of the LED module when a call arrives. If the slider is active, the system will send a signal to the camera with each call.
It is worth considering that on different versions Android the menu structure may look different. In older versions, for example Android 8 or 9, this parameter is sometimes placed separately in the “Special” section. opportunities" without additional subcategories. In newer versions, such Android 12 and above, Google often changes the layout of elements, hiding them deeper in the menu to simplify the interface. If you don’t find the switch right away, try using the search bar at the top of the settings screen by typing in the query “flash.”
⚠️ Attention: On some budget smartphones, the manufacturer can programmatically restrict access to flash control in the system settings, leaving only the automatic operating mode.
After you find the desired toggle switch, it must be set to "Off." Changes are usually applied instantly, but to be on the safe side, it's best to reboot your device. This ensures that the system services responsible for processing incoming calls will correctly update their configuration files and stop sending a signal to the LED.
Disabling the flash on Samsung smartphones
Owners of devices from the South Korean Samsung corporation are faced with a shell OneUIthat has its own unique menu structure. Here, the control of light signals is placed in a separate, fairly easily accessible section. To begin, open the standard application Settings and scroll the list to the item Accessibility. This is the central hub for all functions that make it easier to interact with the device.
Inside the accessibility section, you need to find the “Improving Hearing” subsection (sometimes it may be called “Hearing”). This is where the desired “Flash on Notification” toggle is hidden. Unlike many other manufacturers, Samsung allows you to manage this setting very flexibly, separating settings for calls and general app notifications. Make sure that you disable the function that responds to calls if you want to keep flashing for messages from instant messenger.
If the standard path seems too long to you, you can use an alternative method through the “Phone” application. Open the dialer, click on the three dots in the corner of the screen to open the menu and select “Settings”. Next, go to the "Notifications during a call" or "Answer and end a call" section. There may also be an option to control the light indicator, although in the latest versions OneUI it is often duplicated or completely transferred to the general system settings.

Configuring Xiaomi, Redmi and POCO (MIUI/HyperOS)
Ecosystem users Xiaomi, including brands Redmi and POCO, work with shell MIUI or new HyperOS. The logic here is different from stock Android. Often, setting the flash during a call is not in the accessibility section, but directly in the application for making calls. Open the application Phone (green tube), click on the three horizontal stripes or dots in the upper right corner and select Settings.
In the list that opens, look for the item “Incoming call” or “Answer and end a call”. Inside this menu there should be a toggle for “Flash on incoming call”. If you are using an older firmware version, the path may be slightly different: Settings → Advanced settings → Accessibility → “Hearing” tab. In new versions HyperOS the company strives to unify the interface, so settings can migrate between the system menu and the menu of the application itself.
Particular attention should be paid to the “Pocket mode” or “In pocket." In some configurations MIUI the flash may be activated as part of this mode of protection against accidental clicks. If you turn off the main switch but the light is still flashing, check your lockout and pocket mode settings. Sometimes clearing the cache of the Phone application through the app management menu helps, since old configuration files may conflict with new settings.
⚠️ Attention: The MIUI and HyperOS shell interface is updated frequently. If you do not find the described item, use the settings search by entering the word “flash” or “flash.”
For advanced users, it is possible to use themes. Some third party themes may force you to enable or ignore system flash settings. If all else fails, try temporarily changing the theme to the standard one (“Classic” or “No Theme”) to eliminate the influence of third-party code on the operation of system indicators.
Control via the Camera application
Few people know, but on some smartphone models, especially from manufacturers like Meizu, ZTE or Lenovo, control of the flash during a call is tied to the settings of the camera module itself. It seems counterintuitive, but technically the camera is responsible for emitting light. Go to the application Camera and open its settings (usually this is a gear icon or three bars).
In the list of options, look for the section related to “Shooting mode” or “General settings”. There may be a “Notification Flash” or “LED Indicator” item. If this option is enabled, the camera goes into standby mode when the screen is locked. Disabling this feature in the camera app can completely block the possibility of blinking, even if the phone's system settings have the permission set.
It's also worth checking if you have third-party camera apps installed that could intercept control of the LED. In such cases, the default application may not have access to full settings. In this situation, it is best to temporarily remove third-party software to check or reset the camera application settings to factory settings through the app management menu (Settings → Applications → Camera → Memory → Clear data).
Why do camera settings affect calls?
The Android system architecture allows applications request access to hardware resources. The Phone application sends a request to turn on the light, but the camera driver executes it. If the Camera application is set to prohibit the use of the flash in the background or for system events, the light will not light up, regardless of the dialer settings.
Using third-party applications
If the built-in means fail to turn off the flash, or if, on the contrary, it does not work where it is needed, applications from the store come to the rescue. Google Play. There are many utilities, such as “Flash Alerts”, “LED Blinker” or “Call Flash”, which take control of the indicator. They allow you to create more flexible profiles: for example, flash only for contacts from your favorites list or use different color schemes for different subscribers.
However, installing such applications has its own risks. They require constant permissions to run in the background, access contacts and phone status, which can negatively affect the autonomy of the device. In addition, having two apps trying to control the same LED (system and third-party) can lead to conflicts when the flash begins to blink erratically or stops responding to commands at all.
Before installing any application, carefully read reviews and check the list of permissions. If a simple “dialer” requires access to your geolocation or microphone without obvious need, this is an alarming signal. It is better to choose applications with open source code or from well-known developers who specialize in system utilities rather than data collection.
| Application name | Control type | Impact on battery | Presence of advertising |
|---|---|---|---|
| Flash Alerts 2 | Full control | Average | Yes (in) |
| LED Blinker Notifications | Flexible profiles | Low | No |
| Call Flash - Caller Screen | Replacing the call screen | High | Yes |
| System Default | Basic | Minimum | No |
If you use a third-party application to control the flash, be sure to give it autostart in the energy saving settings, otherwise the system will “kill” the process in sleep mode and the light will not light up.
Solving problems and software conflicts
There are situations when you have turned off all possible switches, but the flash continues to flash treacherously during a call. Often the cause is software conflicts. For example, you could install a theme that forces this effect, ignoring system settings. In this case, returning to the standard theme or removing recently installed visual add-ons will help.
Another common reason is cached data from the Phone or Contacts application. The system may have remembered the old user profile in which the flash was turned on and is applying it with priority. To solve the problem, you need to clear the cache and data of these applications. Go to Settings → Applications → Phone → Memory and click Clear data. Don’t worry, the contacts will not be deleted, they are stored in the cloud or on the SIM card, but the dialer settings will be reset to factory settings.
It is also worth checking if the “Not” mode is enabled disturb" with special exceptions. In some implementations Android when this mode is activated, the system can ignore the sound, but compensate for the lack of melody with visual effects, including a flash. Check your Do Not Disturb settings to make sure there are no settings that force the lights on for your favorite contacts.
⚠️ Warning: Resetting the Phone app may delete your call history if it's not synced with your Google Account. It is recommended to make a backup copy before clearing data.
If software methods do not help, there may be a hardware failure or an error in the firmware of a specific (batch) of devices. In such cases, the only help is to wait for a system update from the manufacturer or, as a last resort, to completely reset the device to factory settings (Hard Reset). However, before taking drastic measures, you should always try to find a forum dedicated to your specific model and look for information about bugs in the current version of the software.
In 90% of cases, the problem is solved either by disabling the function in "Accessibility" or resetting the settings of the "Phone" application.
Questions and answers (FAQ)
Why does the flash blink even when the phone is face down?
This is the default behavior of the feature as it is designed to attract attention when the phone is face down in a pocket or on a table and the user does not hear the vibration. If this annoys you, the only solution is to completely disable the function in the settings, since the proximity sensor in this case does not block the LED.
Does turning on the flash during a call affect the battery life?
Yes, it does, although not critically. The LED module consumes power, and if you take a lot of short calls throughout the day, the total consumption can be noticeable. In addition, frequently turning an LED on and off can theoretically reduce its life, although modern LED elements are designed for hundreds of thousands of cycles.
Is it possible to make the flash blink only for certain contacts?
This cannot be done using standard system tools - the function works globally for all incoming contacts. To implement the “mom only” scenario, you will need to install a third-party application to manage calls or create automation through applications like Tasker, which requires more in-depth knowledge.
The “Flash on notification” item has disappeared, where did it go?
Manufacturers often change the location of the settings or remove them depending on the version of Android. Try using the search in your phone settings. If the search does not produce results, it is possible that this feature was removed in your firmware version by the interface developer.
Will the flash work if the phone is turned off?
No, the flash is an active electronic component that requires power and processor operation to process the incoming call signal. If the phone is turned off, it cannot receive a call and, accordingly, cannot send a signal to the LED.
