On the Samsung Galaxy S7 there is a gallery app preinstalled. When you open it, the images within the albums are displayed in a fairly large preview.
However, if you want to display more previews at the same time as you have a better overview, you must proceed as follows on the Samsung Galaxy S7:
1. From the Home screen, first navigate to the App menu and then open the Gallery app.
2. If you are in the Gallery app, open any album
3. Now use your fingers to zoom out (as when zooming out from web pages, etc.)
4. The thumbnails are now reduced, which means that you will see more pictures at the same time on the display.
You now know how to increase the preview number of thumbnails on the Samsung Galaxy S7 within the gallery.
