Lately, in the Gallery app associated with the camera app of my Samsung phone (Android 8.0.0), I can see not only past pictures I've taken with the phone camera, but also pictures that people are sending me through whatsapp, viber and other messenger/social media apps.
I didn't see any options in the Gallery app itself to have those land not in the same place as my camera-taken pictures.
Is there any way to keep the two categories of pictures (whatsapp attachments; and camera pictures) separated?
