After the most recent Verizon updated to the Note 5 (Jan 2018), I noticed blank photos and blurry images using the gallery app on the phone. In order to resolve, I did the following
Goto settings >apps> >application manager>gallery
Hit the 3 dots in top right corner
everthing back to normal.
This resolved the issue . Hope this helps because this was very frustrating with the blanks and blurries.
