Some of those are a bit greedy, because of the way Android's intent system works. Instead of asking for camera access, it can ask the OS to load the camera and return the resulting picture to the app. Same with making phone calls etc. It doesn't need to do this within the app; it can simply send the intent to the OS to make a call. Unless it's actually adding useful functionality that the OS's (or 3rd party) camera or phone app can't do, then this is all completely useless.
