What causes photos to look normal as a thumbnail, but then look glitchy when viewed in full?

[Android Central Question]

This has happened a few times; I'll take a photo and when I view it straight after, everything looks fine. Then I'll open my gallery to look at it again, and it'll have glitchy colours over it.
Why?!
