Samsung Galaxy K Zoom Camera Issue - Not Sure What it is.

[AC Question]

I bought a galaxy K zoom yesterday. I opened the seal and eagerly checked the camera clarity. The photos were pretty good. So good. BUT, while i turn on the camera, the objects moving infront of me (from the camera view) are seen in some kind of blurred way. But, when i take the photos and videos they are soooooo good. But, WHY I AM GETTING THIS BLURREDNESS ANYWAY? Is that a problem with the camera? THAT COULD BE THE REASON WHY I HAVE TO RETURN THE K ZOOM? Somebody please let me know what could be the issue......
