A:Answer Mine pops out sometimes when I am moving the Ipad around. I found that if I take the time to carefuly set it up on a flat surface, it stays in place. But you are right, the corner clamps dont’ hold it tightly and of course they are only at the top, and there are none at the bottom. On the other hand, they are easy to release the IPAD. My last case required me to pry out the ipad and I was always concerned, I would break the glass, but flexing the frame too much.
