I Heard My Samsung Galaxy S6 Phone Camera Turn On Randomly Earlier

My Samsung Galaxy S6 camera is quasi-broken and had been for a while. When you activate it, it makes a kind of "grinding" noise and takes a few seconds to focus.

Earlier today at work, my phone was on my desk and I heard it start making that sound. All my apps were closed, and the camera "viewfinder"/screen was not on. Everything looked normal.

Is is possible/probable this an app spying on me? Whom would you prime suspects be? If not, what could cause the camera to randomly turn on?

Thanks!
