I went for a jog yesterday, it was pretty hot and humid but not terribly so. I had my ip5 in the armband that I've used for my 4s w/o any issues. But yesterday after a few hours I thought I'd snap a few photos of some things I was going to sell and noticed everything had a glow and was out of focus. Closer inspection I saw that there was a yellow condensation that formed inside the camera lens. This never happened w/ my 4s and I probably ran over 1k miles with it in rain, cold, heat, whatever. When I originally got this out of the box there was a nick on the edge where the camera was and I didn't really care but now I wonder if that caused a bad seal where the camera was. I'll probably just take this in for an exchange but wondering if anyone else experienced this.
