Good app, easy to operate, does what it says. The bad thing about it is no camera guard between 8 - 10 PM unless you buy the premium version, which sucks because it's cheap BS spam! Camera Blocker & Guard from Protectstar Inc. always unlocks itself leaving your security exposed, Camera Block always stays locked protecting your privacy unless it's between 8 - 10 PM and they try to extort £6.99 out of you.
