Tf are you on about? I AM looking for a foss camera option. But it is practically non existent. Besides 2, Open Camera and Libre Camera, both of which have a UI from 2012 and Libre Camera lacks a ton of features.
And despite that, GrapheneOS comes with its own open source camera, but there is a reason nobody uses it, it has no features just like the other very limited open source camera apps (Open Camera excluded)
