I just thought I'd chime in my experience. My wife and I both have TMO HTC One's running 4.3 and neither of us had ever had camera issues before (except for me in the beginning when I had to get mine replaced by HTC because the camera couldn't focus.. That was a fun one too...). I used her phone on Christmas morning propped up by the Christmas tree to record what turned out to be a straight hour of video while we and our kids unwrapped gifts... During and since that video being recorded, her pictures and videos often (but not always.. maybe half the time or a little less - I am guessing...) turn out purple coated.... Draw your conclusions. My wife would rather live with it than go without her phone but I sure would like to get it fixed.
