Im looking for a case that will be mostly dust proof. I tired the lifeproof case and it was horrible. Had echo problems and screen protector didn't sit flush. Currently I have a Otterbox defender, surprisingly nice quality when comparing it to my old s3 one, but dust can slip in with the home button cut out and the ear piece. I know of the preserver made by Otterbox and from the comments I read i guess it works some what well with the zagg glass, and the call quality isn't too bad. the only other case would be the life proof nuud. Unfortunately it hasn't been released yet. So are there any other cases that offer dust protection
