Today I opened my gallery, every other section like screenshots, downloads etc is okay but except last 2 months, all my other data from "camera" section isn't there, I remember I never deleted it, it had 1000+ images and videos including all memories and even PICTURES OF MY BANK DETAILS, MASTERCARDS ETC I'd highly appreciate if anyone could guess, what happened, what to do next or any help would be HIGHLY HIGHLY APPRECIATED!
