Guys I used a cover bought from amazon, origami style, and it scratched my voyage on the top left corner

How do you deal with those covers? Is there a way to avoid scrathing? I see that the edges are too sharp and the cover is really tight, so if you keep putting it on and taking it off like I do, I'm afraid you will get your kindle scratched..
P.S. it's the third Voyage in a row that has dead pixels.. See attached image
