The Poetic Slimbook doesn't touch the screen protector.
I also have the Evecase Heavy Duty Hybrid Case with Stand. It causes the screen protector to bubble in the upper-left corner, but I've solved that by sliding my fingernail under the case's edge in that area so it comes down on top on the protector instead of butting up against it. This case comes in three pieces and really protects the phone, even if dropped screen down. This elaborate design also means you won't be taking the N4 out of the case on a daily basis, so once you've got the case and protector situated, it's good to go for quite a while.
