Pictures and videos erased on Galaxy S6

[AC Question]

Hi all, my Samsung Galaxy S6 seems to erase on a regular basis some of my pictures / videos. The pictures are in the Gallerie or Quickpick Apps for a few days and then disappear.
Impossible to find them back (Not available in Google drive, nor in phone folders...)
Any clue about what is happening here?

Hi, do you have any apps installed that "clean" up your phone? this could be deleting them.

I would certainly dump Quicpic. It's operated by data harvesters Cheetah Mobile Popular Photo Gallery App QuickPic Has Been Bought By Cheetah Mobile, And Users Are Pissed
