I've noticed after 2 weeks with the Otterbox defender for the iphone 6 an issue with the rubber cover. Right beneath the finger ID, where the rubber cover meets that black plastic piece on the bottom front, it no linger sits flush and there is a slight gap where it should be completely flush. It only gets worse after I close the rubber door for the charger port. That makes the gap more noticeable. I believe it was completely flush when I first put it on, but after multiple charges and pressing the finger ID, the gap is starting to show. It's not bad or even that noticeable, but I figured it would be getting worse over time. Does anyone else know what I'm referring to? I was going to exchange the cover for a newer version, but I'm pretty happy with the case overall.
