I recommend getting a rugged cover fits the phone such that the camera lens is recessed (i.e, not flush or nearly flush with the case). Some cases on Amazon are marked as "rugged" like the Spigen but do not adequately protect the camera cover/lens. I see a case on Amazon that demonstrates what I mean. Please note that I have no experience with the case I'm linking to. I am using the photo to demonstrate how I believe the camera should be protected.
