The adhesive is not strong enough to withstand the force to move the cover back and forth if your screen is glass

But, the adhesive is horrible & it’s almost impossible to slide the circle to cover the camera.

I think it will work if I can just find some kind of glue that sticks to a screen protector (wouldn't want to stick it to my glass if I had to use a stronger adhesive)
