Damn, that's annoying. It's a bright, sunny day & I've been taking photos of interesting sheds on country roads with the iPhone. Back home, viewing them on the Mac, there's a blur/smear on the end of each pic. Why? Because the lens protector part of the Lifeproof case I keep the phone in has a smudge on it. All the photos will have to be done again. At least the iPhone has recorded the location of each one, so I can go back with the Nikon D5100 DSLR.
