Can anyone tell me why such a basic feature is so hard to find or does not come by default in phones nowadays?
Edit : I meant app lock which uses fingerprint or pattern. I want to apply it to Gallery and other apps. I already have Shelter running on my phone and also have secure folder, but that’s not what I’m for. Sorry if my question wasn’t clear.
The correct way is work profile with separate unlock, use Shelter or Insular to activate and manage the profile, both apps are FOSS.
The other way is user profiles, GrapheneOS improves the UX of them a lot, stock Android is not really usable without reboots.

You would need file manager and gallery.
