In the modern pace of life, we often miss incoming calls due to loud music in the headphones, noise on the street, or simply because the phone is in the bag face down. A standard vibration or melody may not be enough to attract attention. It is in such situations that the function flashes when calling becomes an indispensable tool. It creates a visual signal that is impossible not to notice, even if the device is in silent mode.
Activation of this option on smartphones running Android may differ depending on the shell manufacturer and operating system version. Some models have this feature built into the basic settings, while others require the installation of third-party software or the use of special codes. Below we will analyze in detail all the ways to make your phone blink when a call comes in.
It is worth noting that using LED flashes as an event indicator not only helps not to miss an important conversation, but can also serve as a signal for people with hearing impairments. This is a universal solution that works on almost any device, from budget models to flagships. Let's move on to specific setup steps.
Standard settings in pure Android and Motorola
Owners of smartphones with a “clean” operating system, such as users Google Pixel, Moto or Nokia, more often All have access to this function directly from the settings menu. Google developers introduced the ability to use camera flash for notifications several years ago, making the process as simple as possible. You do not need superuser rights or complex manipulations.
To activate the option, you need to go to the Settings section of your device. Next, find the item Special. features (or Special features). Inside this menu, you should look for a subsection related to hearing or visual notifications. In different versions Android the name may differ slightly, but the logic remains the same.
Find the switch with the name Flash for notifications or Flash on alerts. Activate it by moving the slider to the “Enabled” position. After that, when you receive an incoming call or receive an SMS, the LED flash will fire rhythmically.
⚠️ Attention: On some models Moto the function may be called “Moto Actions” and is located in a separate application, and not in the general system settings. Check the list of installed apps.
If you do not find the item you need in the accessibility section, try using the settings search. Enter the word "flash" or "flash" into the search bar. The system itself will tell you where the required option is hidden. This saves time and eliminates the need to wander through numerous menus.
If the flash does not fire in silent mode, check if it is disabled in the Do Not Disturb profile. Sometimes system priorities block visual signals.
Activating the flash on Samsung Galaxy smartphones
The company Samsung uses its own shell One UIwhich has a unique menu structure. Here, setting the backlight during a call is placed in a separate section related to accessibility. This is done so that users with disabilities can quickly find the function they need. The activation process is quite simple and intuitive.
Open the menu Settings and scroll down the list to the item Accessibility. Inside, select a category Advanced settings. This is where the switch is hidden Camera flash. Some users mistakenly look for this feature in the "Notifications" section or in the settings of the camera itself, which is a common mistake.
After activation switch, the system may request confirmation of the action. Agree with the warning that the flash will be used for signaling. Now, when there is an incoming call, the back panel of your Samsung Galaxy will flash brightly. This is especially convenient if the phone is lying face down on the table.
- 📱 Go to Settings → Accessibility.
- 🔍 Select the "Advanced Settings" section.
- ⚡ Activate the "Camera Flash" toggle switch.
- 📞 Check the functionality of the function by calling your number from another phone.
It is worth considering that on older models Samsung with a physical Home button or without an LED flash, this function may not be available. In such cases, the system can use the screen to flash, but this is less effective. Always check the compatibility of your model with this function before setting it up.
Setting up notifications on Xiaomi, Redmi and POCO
Shell MIUI (and new HyperOS) from the company Xiaomi is famous for its deep customization, but sometimes hides useful functions in unobvious places. Turning on the backlight during a call is also possible here through standard means, however, the path to setting may vary depending on the firmware version. Users often encounter the fact that the standard switch does not work for third-party instant messengers.
The first method is through the app Phone. Open the dialer, click on the three dots or the settings icon in the corner of the screen. In the menu that appears, find the item Incoming calls. There should be a switch Flash on calls. If it is not there, we move on to a deeper level of settings.
The second method is through the general system settings. Go to Settings → Advanced settings → Special features. The tab Hearing contains the item Flash on notification. Activating this item will cause the flash to fire not only when making calls, but also when receiving messages from social networks, which can be both an advantage and a disadvantage.
| Model / Shell | Path to settings | Operating features |
|---|---|---|
| MIUI 12-13 | Settings → Advanced → Special features | Works for all notifications |
| HyperOS | Settings → Sound and vibration → Flash | Separate section in new versions |
| Redmi Note | Phone application → Settings | Only for incoming calls |
On some devices Xiaomi with AMOLED screens, the function Always On Display may conflict with flash operation if the battery is discharged below 15%. The system automatically turns off energy-consuming features to save battery. Take this nuance into account if the function suddenly stops working.
Secret code for verification
On some MIUI firmware, you can enter the code ##6484## in the dialer to enter the engineering menu and check the operation of the LEDs manually.
Use of third-party applications for flashes
If the built-in tools of your smartphone do not allow you to enable the desired function or do not work correctly, applications from the store Google Playcome to the rescue. There are many free utilities that intercept the incoming call signal and force the LED flash or screen to activate. This is a universal solution for any version Android.
One of the most popular solutions is the application Flash on Call. It's lightweight, doesn't require complex permissions, and runs in the background. Once installed, you will need to provide permission to access your camera and phone. In the application settings, you can select the operating mode: only for calls, only for SMS, or for all notifications.
Another powerful tool is LED Blinker Notifications. This application allows you not only to turn on the flash, but also to configure the flashing color (if your phone has a multi-colored LED), frequency and duration of the signals. You can set a unique flashing pattern for calls from a specific contact, which will make caller identification even more convenient.
- ⬇️ Download an application from Google Play (for example, “Flash Alert”).
- 🔐 Grant the necessary permissions when you first launch.
- ⚙️ Configure sensitivity and blinking mode in the application menu.
- 🔋 Add the application to power saving exceptions so that the system does not “kill” its process.
It is important to understand that using third-party software increases battery consumption. Applications constantly monitor the state of the phone, which creates additional load on the processor. However, for most modern smartphones with capacious batteries, this impact will be minimal and unnoticeable in everyday use.
⚠️ Attention: When installing third-party applications, carefully read the permissions. If the flash app requires access to your contacts or microphone without obvious need, it is better not to install it for security reasons.
☑️ Checking the application operation
Adjusting color display and screen
Modern smartphones offer not only standard white flash, but also more advanced visual notification options. The function Edge Lighting (backlighting the edges of the screen), popular on devices Samsung and some custom firmware, allows you to color the display borders in different colors when a call arrives. It looks aesthetically pleasing and noticeable even during the day.
To customize the color scheme, go to the notifications section and find the item Notification style or Edge highlighting. Here you can choose a static color or a gradient that will light up when you call. Some models allow you to link the color to the wallpaper image or the color of the caller's avatar, which adds personalization.
It is also worth mentioning the function Screen flash. If your phone doesn't have an LED flash or it's too dim, the screen may flicker with a white or colored background. This setting is usually found in the same section Special featuresas the LED flash setting. The screen flashes several times, attracting attention, even if the phone is face down (on some models with a proximity sensor).
The use of color indication is especially useful in the dark. A sharp white flash can be blinding, while a soft colored glow from the edges of the screen or a pulsating notification light (if there is one) is less invasive. Experiment with settings to find a balance between visibility and comfort.
Edge Lighting is a great alternative to flash for smartphones with AMOLED displays, as it consumes less power and looks more stylish.
Possible problems and solutions
Despite the ease of setup, users may encounter a situation where the flash does not fire. The most common reason is an aggressive energy saving system. Android tries to extend the operating time of the device, so it automatically closes background processes, including notification services. To fix this, you need to add the Phone app or flash app to the exception list.
Another common problem is with Do Not Disturb (DND) mode. In this mode, the system blocks all audio and visual signals, except for calls from selected contacts. Check the settings of this mode: perhaps the visual notification option there is forcibly disabled. Also make sure that the flash brightness is not set to minimum in accessibility.
If the flash blinks, but very faintly, it may be a hardware issue. Over time, LEDs degrade, but most often the problem is a software brightness limitation in the accessibility settings. Try resetting your accessibility settings to factory defaults and setting them up again. In rare cases, clearing the application cache helps Settings.
⚠️ Attention: Excessive use of the flash during a call can lead to overheating of the camera module, especially in the summer. Take breaks or turn off the feature if your phone gets hot.
In case of software glitches after a system update, the feature may disappear. Then it is recommended to check for updates for the application Google Play Services or roll back application updates Phone to the factory version through the app management menu. This often restores lost functionality.
What to do if nothing helps?
Try installing a trick application from the manufacturer (for example, Good Lock for Samsung), which allows you to customize the system more deeply, including the lock screen and notifications.
Frequently asked questions (FAQ)
Does the flash during a call affect the service life of the LED?
Modern LEDs are designed for tens of thousands of hours of operation. Short flashes during a call will not have a significant impact on their resource. However, constant use of maximum brightness may slightly accelerate the degradation of the crystal after several years of active use.
Is it possible to set blinking only for certain contacts?
It is difficult to do this using standard means. Typically the setting is applied globally to all calls. For individual settings for a specific subscriber, it is better to use third-party applications, such as Android this is difficult to do. Typically the setting is applied globally to all calls. For individual settings for a specific subscriber, it is better to use third-party applications, such as LED Blinkerthat allow you to create notification profiles.
Why does the flash not work when the phone is unlocked?
By default, the system often turns off visual notifications when the screen is active and you are using the phone, believing that you already see a notification in the curtain. In the accessibility settings, look for the option “Flash even when the screen is unlocked” and activate it.
Does this feature drain the battery?
Yes, using the flash consumes energy. One call with flashing uses a small amount of battery, but if you have dozens of missed calls or active messaging in instant messengers with the flash on, by the end of the day you can lose 3-5% of the battery charge.
Does this feature work on Android tablets?
Most tablets are not equipped with an LED flash, so the visual function Alerts are provided through screen flashing. The setup is carried out similarly to smartphones in the “Special Features” section, if the manufacturer has not cut this option in the firmware.
