Tested on Samsung Galaxy S2, Samsung Note 3, Nexus and Samsung Galaxy Ace and other mobile phones.
Simple torch application DOESN'T collect any personal information. Unfortunately it requires camera right as it is not possible to control camera light without it and there is no possible to ask only for right for camera light.
