This flashlight will illuminate everything around you.
This flashlight turns on the camera flash and the device screen on maximum brightness, fully illuminating the environment.
If you do not have flash, or if your flash is not supported, only the screen is turned on maximum brightness.
Widgets can be added anywhere, even on the lock screen of the phone.
If your android is the 4.3, you do not need to unlock the phone to activate the flashlight.
