Johnathan_ybq32Mz7rX I went down that rabbit hole, and as far as I know no phone manufacturer allows full resolution images (with more than 12MP) in expert mode. That's why expert/pro modes are mostly confined to 12 MP. I think sonce pro modes often provide raw image support, this is to prevent people from flooding their phones with huge raw images, that look too noisy for most people, but i'm not sure.
I hope Nothing will allow users to take 50MP raw images in expert mode, or at least 50MP non-raw images or at the very least allow third party apps to capture full resolution images, but looking at common practices in the smartphone world, I am not expecting them to do that.
