Thanks to various people forwarding messages all over, you might be getting a lot of the images and videos in your Gallery. If you don’t want incoming media on Whatsapp to show up in the Gallery, hide them using this simple trick.
Open File Manager and browse to Internal storage WhatsApp > Media and Rename “WhatsApp Images” and “WhatsApp Video” folders to “.WhatsApp Images” and “.WhatsApp Video” respectively (notice the dot in start).
Note: This trick is applicable only for Android, not for iOS platforms. And this will hide the images and videos from your phone’s gallery but you can see them in your WhatsApp as well as using a file manager.
