No device protection here. I have never damaged a phone in all the years I have owned them. Get a great case and a screen protector and you will be fine. My choices I have a Speck Presidio Grip (Black). Was hoping for a clear one like they make for many other phones. I didn't want a white one or a frosted one because of too much white. The black balances the white out nicely and the blue fingerprint sensor and cam lens show up pretty cool against the black.
For screen protectors I have an invisible shield Glass + It isn't the greatest fit in terms of completely covering everything, but the general consensus is that none of them fit properly. Got them both from Verizon where I purchased my phone. Phones only get damaged if you are not careful or careless with them. I never take the case off though unless I am cleaning the phone then it goes right back on
