If you are worried enough to cover your PC camera all the time, why aren't you worried enough to cover your phone camera all the time anyway? And are you OK to connect your phone to your potentially compromised PC with a USB cable in non-camera mode? That seems just as bad or worse. I expect that on most phones you will have to select USB camera mode for it to work (and you'll have to tell it if you want the front or back camera), and it will probably tell you that it's working on the screen.
