All the currently available Free Flash light Apps in the market, require permissions to your Contacts, Gallery, Messages, Location, Microphone, Storage, SMS, Wifi Info, Phone etc. Have you wondered why?
As an Android programmer I can confidently say these permissions are not needed at all except for the camera.
All other permissions ‘May’ have malicious intent.
Here is an App that only requires permission to the Camera (only because the Flash Light is a part of a Camera).
Install it without any fear!
