Camera photos show up black with an exclamation mark?

[AC Question]

So, today I noticed my internal phone storage was almost full, so I decided to move all of my photos to my SD card. After doing so, majority of my recent CAMERA photos were replaced with a black thumbnail, with a gray box and a grey exclamation mark. I tried moving them back to my internal phone storage, but they remained in the same condition. Please help!

This only happens to me when I take a screen shot and open it instantly. The files may be corrupt.

Is there any way to fix it?
