Torch

This is the simplest torch application you can get. It takes only one permission "android.permission.CAMERA" which is required for LED lighting. It will work on all Android device and will occupy minimal space of your memory. It also turns the light on when started so you don't have to click two irritating buttons before turning the light on. It will keep the light on when you lock your phone or press home screen button. To turn the light off simply click the off button or back button of your phone.
