I TOO have. Lifeproof. Awsome cases and waterproof. My old one did start to separate between the edge of the clear screen protecter where it met the rubber. But overall awsome cases. I got a came stick on Camo peice for the back of mine.
Waterproof, yes. iPhone replacement guarantee, good.
Had one, took it back and got an Outerbox. Being waterproof seals in the phone...and the sound(s). The ringer, call sounds, text sounds and voices of people that call are cut in half. I don't need that much protection, as opposed to being able to hear the functions of my phone.

I had the same issue.. It sounded like whoever I was talking to was in a box, and they said the same about me. As soon as I took the case off all was good..
