I have a rooted Galaxy A3 2017 (SM-A320F) running Android 8.0.0. I'm trying to capture raw photos, but neither the stock Camera app nor Open Camera show any relevant options (I have enabled Camera2 API). This option wasn't present before rooting too. On another phone, unrooted Galaxy Note8, the option is present at least in Open Camera.
So I suppose the option is somehow disabled in my A3. Can it be re-enabled without switching to a completely different firmware? How?
Note that another question proposed as a duplicate is 1) asking about very old version of Android — 4.2.2, which doesn't have Camera2 API, and 2) asks simply whether there exist any apps with such functionality, which today is of course yes. So this one is not a duplicate. This question is about how to re-enable the missing raw photo support instead.
