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?
