I just had mine replaced due to that issue, and the seams on the plastic, and the phone mic didn't work right, andd the screen had like 10 dead pixels lol.
Anyways got the new one back hoping for the camera to magically be better..it isn't. Still junk lol. Semi sharp and tons of noise in the picture. As soon as you zoom in for detail BAM noise. It is a phone camera and hey, at least it doesn't go purple anymore right? Oh my phone was in like new condition when it came, zero scratches (or it would have been sent right back to them).
