I noticed since the moment I unboxed my Cosmo that the camera glass isn't very well affixed, at least on one side. I've pressed it back down several times and it keeps coming back up on one side. I've been pondering sicking it under my microscope and very carefully getting a little bit of glue into that seam to hold the glass in place better.
Edit: I notice you are in Sweden. I'm in Finland, so assuming you have the local keyboard layout on yours, our Cosmos are quite possibly from the same batch.

Camera glass on my Cosmo is also asymmetrical, but just a little bit. Not so dangerous but anyway. Many parts of my Cosmo's case feel very chinese. Big gaps, wonky parts. I don't care too much about it but for $750 device it's ridiculous
