This widget can be placed on your home or lock screen to activate your camera LED for use as a flashlight. Tap on the widget once to activate the light and again to deactivate. Only the camera access permission is required.
** This is purely a widget so there will not be any app icon added to your launcher. Instead, it will appear as a widget called "Flashlight" under your widget menu.
** Other applications which require camera access will not work while the LED is turned on. Remember to turn it off when not in use and do not stare into the LED light.
** Tested on the Nexus 4
