Why have my pictures disappeared off of my Samsung S5 phone? How can I get them back?

[AC Question]

The squares or shapes are till on the phone to show where a photo was They maybe on there for a couple of days then disappear.

Let's start with what mods or hacks have you done to the phone if any?
If your phone is all stock then we have too look at where the camera is sending the pictures, get a file explorer (i recommend es file explorer) and look for a folder named DCIM. Your pictures should be located in that folder.

Where does one find this file explorer? Is it something I have to purchase? Or is it on the phone presently?

Samsung's My Files is a file explorer and that's already on your phone
