Too tight and adhesive residue on the phone!

I've ordered my pocket for my Lumia 920. Unfortunately, even this bag, like many others before, too tight! When put on and take Adjust the side keys are pressed and therefore the display is activated! Something should not happen in such an expensive bag! I also had on my Lumia after the first par times try adhesive residue. I do not know where it comes from ... I returned the bag repays!
