📸 Favorite camera app for Android?

I've actually just been using Signal's built in camera app, which has been fine, but doesn't seem quite up to par today (or maybe I'm just in a mood). Does anyone know if there's a way to reset Signal's camera app settings? Otherwise I just use Graphene's camera, which might also be fine (maybe I need to get my eyes checked). Anyway, any camera apps that automatically take great pictures? I'm trying to photograph some old drawings for posterity.
