The most obvious and common way to find and turn on lighting is to use the quick settings panel, often called a “blind”. To access it, you need to unlock the smartphone screen and swipe your finger from top to bottom across the entire display area. In the menu that opens, you will see a grid with icons for various functions, among which there should be a button with an image of a flashlight.
If you do not find the icon you need right away, it may be hidden on the second page of the panel. Swipe horizontally left or right (depending on the version One UI) to see additional buttons. Often, users accidentally delete this icon when editing the list, so it is worth checking whether it is in the list of available but inactive elements.

In some firmware versions, holding the icon for a long time allows you to go to the detailed settings menu, where you can select the brightness level or color of the glow, if the device model supports such capabilities.
⚠️ Attention: Do not leave the flashlight on for a long time unless necessary. Intense operation of the LED leads to rapid heating of the smartphone body and significant battery consumption.
Add a flashlight icon to the top row of the quick settings panel through the editing mode to turn it on with one touch, without opening the full curtain.
Using gestures and buttons control
The company Samsung has introduced into the shell One UI many convenient functions for controlling the system without having to touch the screen. One of these features is to activate the flashlight by double pressing the lock button. This feature is especially useful when the phone is in a pocket or bag and you need to quickly find the lock or keys.
To use this method, make sure that the corresponding option is activated in the settings. It is usually enabled by default on new devices, but can be disabled by the user previously. The principle of operation is simple: when the screen is off, quickly press the side power button twice, and the camera flash will instantly light up.
In addition to the power button, some models support control through gestures on the display off or through the proximity sensor. For example, on some devices you can swipe down with two fingers on a black screen (feature Quick gesture) to launch the flashlight. However, this option is less common and depends on the specific modification of your Galaxy.
Adding a widget to the home screen
For those who prefer to have constant visual access to important functions, placing a widget on the desktop is an excellent solution. This allows you to turn on backlight right from the home screen, without opening the notification panel or using physical buttons. The widget can be made in the form of a large button or a compact shortcut.
The process of adding a control is intuitive and takes only a few seconds. You will need to hold down an empty space on the main screen until the settings menu appears, and then select the section with widgets. In the list of available tools, find the Settings application or a specialized flashlight widget, if installed.
After selecting the desired size of the widget, drag it to a free area of the screen. Now, when you click on this icon, the smartphone will instantly activate the LED. This is especially convenient for older people or in situations where maximum interface responsiveness is required.

|---|---|---|---|
| Button flashlight | 1x1 | On/Off | All models |
| Control panel | 4x2 | Many functions | One UI 4.0+ |
| Settings shortcut | 1x1 | Go to menu | Android standard |
| Third-party widget | Various | Timer, SOS | Depends on the application |
The widget on the home screen provides the fastest access to the function without the need to unlock phone or swipe across the screen.
Voice control and Bixby assistant
In the era of artificial intelligence, controlling a smartphone with your voice is becoming increasingly popular. Owners Samsung can use the built-in assistant Bixby or third-party solutions from Google to activate the flashlight without even touching the device. This is an ideal option when your hands are full or the phone is far from you.
For this function to work, you must first configure the voice assistant and make sure that it recognizes the “Turn on flashlight” or “Turn on flashlight” command. After activating the assistant, just say a trigger phrase (for example, “Hey, Bixby”), and then voice the command. The system will process the request and apply voltage to the camera LED.
It is worth noting that voice control requires an active Internet connection for cloud processing of some commands, although basic functions often work offline. It is also important to speak clearly and intelligibly, especially in noisy environments, so that speech recognition algorithms correctly interpret your request.
If the standard assistant does not respond, check the permission settings in the menu Applications → Bixby → Permissions. Make sure the app has access to the microphone and the ability to control system functions. Sometimes, after security updates, access rights may be reset.
Adjusting brightness and additional settings
Many users do not know that the built-in flashlight on smartphones Samsung often has adjustable settings. Depending on the model and software version, you can change the intensity of the glow, which is useful for saving energy or not dazzling your interlocutor in a dark room.
To access advanced settings, long press the flashlight icon in the quick settings panel. A pop-up window will open with an adjustment slider. By moving it, you can set the brightness from minimum to maximum. On some flagship models, the function of changing the color temperature or turning on the color signal is also available.
On the Galaxy S24 series and later, an adaptive flashlight brightness function is available, which automatically adjusts the light intensity to the ambient light. This prevents unnecessary power consumption in situations where full illumination of the LED is not required.
⚠️ Attention: The settings interface may differ on devices with custom firmware or on phones purchased in certain regions. Always check the official manual for your specific modification.
Secret strobe mode
In some versions of One UI, quickly pressing the flashlight button repeatedly in the settings may activate a strobe mode, useful for sending distress signals.
Problem solving: why the flashlight doesn’t work
A situation where the flashlight stops turning on or does not work correctly can arise for a number of reasons. Most often, the problem lies in a software glitch, an application conflict, or physical contamination of the camera module. Before contacting the service center, it is worth performing a number of independent checks.
First, check to see if the flash is being used by another application in the background. A camera, voice recorder, or QR code scanning apps may monopolize access to the LED. Close all recently opened apps through the multitasking menu and try turning on the flashlight again.
If software methods do not help, try soft rebooting the device. Press the power and volume down buttons simultaneously for 7-10 seconds until the logo Samsungappears. This action will clear the RAM and restart the system services responsible for managing the equipment.
In rare cases, the problem may be due to physical damage to the LED or camera cable. If your phone has recently been dropped or been in contact with moisture, there may be a hardware problem. It is also worth checking for system updates in the menu Settings → Software update, since manufacturers often release patches that correct such errors.
