I have used Nanobloc webcam cases on 2 devices. The product covers part of the screen on some devices, but I haven't seen one that doesn't cover it when the webcam is in such a small area so close to the screen. I believe that most new smartphones also cover part of your screen. The product works great once you know the tricks. Put a drop of water on your finger and touch the back of the Nanobloc webcam cover if it's not sticking. And if the camera isn't flush with the surrounding area, press firmly in the center to make the suction cups stick to the camera. I like that they are small and soft, I don't have to worry about damaging my laptop.
