I didn't see this exact issue posted and excuse me if it has already been. When I am working outside and I'm trying to take a quick picture with my black, Verizon, 128gb 7 Plus 10.0.2, it's very blurry for three to five seconds when I first click on the camera app? It doesn't do it every time, but it's annoying when it does because I have to wait to take the picture. I'm thinking that it might be fogged up, when I'm exiting out of my air conditioned truck to the 85 degree heat and high humidity. I have tried wiping it, but it usually clears up just as I'm getting my finger on the lens. I've never had this happen with any other iPhone cameras while outside in any temperature and I've had a bunch. Does anyone have any idea what it could be please?
