I have loved my iPhone 6 camera. Today, all of a sudden, I can't get a clear vivid focus. I cleaned the lens, restarted, tried everything I can think of...it is not just the inherent app, though, as my Camera+ is doing the same thing (that's why I figured it was the lens). What in the world could be the problem? (Yes, I tried tapping on the screen in the area where I want a clear focus, still extremely blurred).
