not suitable protection

After trying several times in different ways, I find it impossible to match the protection WIKO CINK Peax - At no time I was able to focus the camera aperture without the protection starts cantilevered down resulting in a huge bubble that I could enlever.J'ai therefore tried to start from the bottom up towards the camera and then open the cover automatically rises partly on caméra.Alors cell that it is sufficient just to simplify the installation of larger a little hole in caméra.Au instead of putting the cover in the trash I'd rather return it to KINGHIGHTECH.
