Transparent protection screen very good, helpful but fragile pen, rigid protection blah

The rigid protection does not pose screen by folding a part of it (as shown on the photos to sell this article).
I also encounter the following problem: When the protection covers the objective of the camera that it is on the back of the tablet, this puts the tablet in standby (which does not happen with ELTD® high quality cover for Lenovo Tab A10-70). Unable to find an option that prevents this action in tablet options (which makes this unusable article). So I bought ELTD® high quality cover for Lenovo Tab A10-70 that much best. I do use that pen and transparent protection of this purchase :-(.
