Unavoidable issue of modern cell phones is that they have a front and rear side camera covering almost a 360deg view. And that some applications like, say Facebook request access for everything. So basically a normal user has at least an app that has camera permissions, and even though they intend to use it rarely, there's no info about when it turns on.
My question is, is there a way to monitor when do apps that have those permissions actually turn on the camera?
(Let's narrow it down to Android)
