The problem with the pop-out corner I had. This is probably due to tensions in the plastic. The solution has helped me the following (without Geäwhr !!!): warm cover on a wooden board in the oven at about 60-70 degrees, and then invert after slight cooling to the Nexus 7. Then it should as 'cast' sit and also the corner no longer pop out (works for me for 3 weeks!). Must course actually in such an expensive 'premium' Cover not be.
