Samsung’s Gallery app is more than just an image and video viewer. It lets you edit images and videos, turn images into collages and GIFs, and remove backgrounds and undesired objects from images. You can also enable Gallery Labs — a secret menu in Gallery — to unlock additional functionality like album-entry locks and the ability to save images as a PDF.
But that’s not all. Samsung offers a Good Lock module that extends Gallery’s functionality even further. It’s called Gallery Assistant, and it can be really handy if you need to carry out batch image and video operations/manipulations on your Galaxy phone.
