Default [Q] Fuzzy camera on some texts

Hi, I recently had to send back my HTC One because of the camera having problem with purple/reddish tint. Just recently my camera is now having problems focusing and is incredibly blurry to the point where I cannot read "small text".
I just took this recently from my text book, the text is incredibly blurry.
 



Here's another one that is clear.
 


I have tried refocusing, but it just gets blurier.
