7plus iphone camera not focusing

Q:

iPhone 7 - camera cannot focus/blurry on far objects

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. It is only focus on something that is very close to the camera. Not sure if this is a brand new issue...? Anyone else know how to fix this? Thanks.
