Note 10 plus camera (but samsung camera in general) image processing is very poor.
You have the best hardware but you waste everything with software.
Promode only works with the main camera, which is also the only camera that complies with camera 2 api (at least on exynos and since ui2.5).
Please open up the other cameras to comply with camera 2 api, allowing them to be used in both other camera applications and in your own camera application pro mode.
Better camera pictures mean better sales.. it's like a no brain.
