Ok not saying that this will work,
But check the white balance setting on the camera (if you can) and reset it by pointing the camera at a white surface.
Failing that make sure that the camera is set to auto.
Just a logical thought
I already tried that and it just seems like nothing is working the worst thing is I cant even send it for repairs coz the note 5 wasn't released in UK. I reset my camera settings and it went back to normal for a few minutes and then went back to being white and blurry. I even took before and after pictures and u can even see the difference.
Apologies, I have no idea what the problem could be. I'm assuming that the both the lens & the light sensors are undamaged and not partially covered by a case or similar.
I came across the following thread when I googled looking for a solution
Though I'm sure you're tried the same route
