The camera uses two different technologies for focus. When you focus through the viewfinder, the camera uses phase detection for focus. When you activate live view, the camera uses contrast detection. Contrast detection is available only in the live view mode because it needs the camera's sensor.

Recently got my iPhone 7 two weeks ago when it was released. My camera was working fine but for the past two days when I try to focus on a person/object far away it remains blurry. It just doesn't sharpen or focus on the person/object. TYgL.
