Bulging camera -> broken glass. For two years I've been using a Galaxy S5 with bulging camera and twice I have broken the camera glass needing replacing, it's the first thing to hit the surface when i rest the phone on a table and takes a lot of stress. Of course I could be more careful. It has also scratched and so there's more lens flare, but I'm tired of replacing it. My wife's iPhone with flush camera is much less of a problem.
