Flashlight & LED Torch description

The icon for the app simply turns your LED flash on or off. That's it. It doesn't change colors or shape when the light is on or off. It's just a simple tap that makes light happen in the back of your device.
Torch Flashlight is another older flashlight app with a good pedigree. It also uses both the screen and/or the LED light on the back of the phone. Like most, it's a free app with some advertising.
