That's the thing, this was the very beginning of the smartphone era, 2007-2009. UX was not fleshed out yet. Conventions neither. Simple gallery apps were an Apple and iPhone thing.

There were cases where phones were not consistent. Pictures from the camera, or saved from MMS, or saved from the Web, or screenshots, did not all go in the same place. Just like you would have on a desktop :) I don't remember that well the pre-2010 android, but it had some issues too.

Even to this day, WhatsApp saves photos to the gallery, but in its own album. At least on iOS those are part of the regular gallery so you'll always find them (an album is just a "tag" on the photo). Android has a dedicated album too, but the picture set is distinct from the main picture gallery. So are screenshots. That's more control and power, but utterly confusing for older people. Younger relatives are fine, older fail to navigate around this and find "the picture your auntie sent to me through whatsapp". Yup, it's there, but not in the main camera roll.

This is what I mean by "you know where the pictures are going".

PS: Apple botched the UX of the gallery app in the last two iOS versions so much that even I, a young tech-inclined person, loses my way around. So do my relatives. They're sorta catching up /s
