LG G5 Camera Not Focusing

Bought the G5 six months ago and suddenly the auto focus is not functioning. The camera will focus and then un-focus in a repeated cycle, every half second.
Searching the internet does not come up with anything expect one person who took his phone into Sprint and they replaced his camera with a donor camera.
There are various complaints on this issue but no true fix.
