Looking at the picture, it does look as if the plastic housing surrounding the buttons and camera lens would come off with no difficulty. If you decide to proceed, try just loosening those two screws to see whether the plastic housing can then be moved a little. If it does move, you could unscrew fully and remove it, but take care that there are no springs inside which might fly out, and proceed carefully so that you can see the exact layout of parts underneath. Quite possibly, however, what is underneath will be fairly simple, but better safe than sorry.
I wish you every success!
