Samsung Galaxy S4: How to Use It as a Flashlight in Android 4.4 Kitkat

I believe that most of you ever hear or know that some phones can act as a flashlight or torch light. In some conditions, this ability will be so helpful for instance when you want to search something in the dark or when you need a portable light for any purpose. Actually, Samsung Galaxy SIV has no default option to let you set the phone as the torch light, but you still can do so by using the assistive light widget. This widget will allow you to instantly turn on or off the camera flashlight with a single tap. It'll be easier than you have to open the Camera app and then turn on the flashlight from there.


How to add the assistive light widget to the Home screen?
Before using the phone as the torch light, you have to add the assistive light widget to the Home screen by using the following steps:
  1. Long tap on any free space in Home screen.
  2. On pop up menu select Apps and widgets.
  3. Tap Widgets tab.
  4. Swipe the screen to the right or to the left until you find Assistive Light 1x1 widget.
  5. Tap and hold the widget to move it to the Home screen.
  6. Release the widget to place it in the Home screen.

How to use the phone as a torch light?
If the assistive light widget has been added to the Home screen, then now you're ready to use the phone as a flashlight by using the following steps:
  1. Turning on the flashlight
    Tap the assistive light widget icon in the Home screen to turn on the camera flashlight. When the flashlight is on, the assistive light icon in Home screen will turn green and the white light icon will be displayed on the status bar.
  2. Turning off the flashlight
    Method #1: Through the Home screen
    • Tap the assistive light widget icon in Home screen to turn off the camera flashlight. The assistive light icon in Home screen will turn grey and the white light icon on the status bar will disappear as a sign that the flashlight is turned off.
    Method #2: Through the notification panel
    • When the screen is unlocked or locked, swipe down the top of the screen to open up the notification panel
    • Tap the assistive light notification to turn off the camera flashlight. The assistive light widget icon in Home screen will turn grey and the white light icon on the status bar will disappear as a sign that the flashlight is turned off.

FYI, since the widget can't be customized and can't be turned on or off automatically, therefore the flashlight will stay on even when the screen is off unless you turn it off manually through the Home screen or the notification panel.
