I bought one of those cheap TPU cases till my Ionic Guardian arrives. The volume rocker was covered over and difficult to press, so I used a knife to cut a whole in the case so I could get to the buttons. Problem is now though, I can only press the buttons using my nails. My fingers don't fit in the hole, and my nails occasionally slip off the volume key, but I can just about use the rocker. Just wondering if me pressing with my nails could do any damage to my phone, or isn't the phone as delicate as I'm thinking?
