Samsung is supposedly working towards delivering major camera updates for its latest Galaxy S23 series devices. A new One UI 5.1 update is slated to fine-tune the camera experience for even the Galaxy S23 Ultra and its 200 MP sensor. According to a reliable leaker, the update could arrive later this month in most markets.https://www.notebookcheck.net/Samsung-Galaxy-S23-Galaxy-S23-Plus-and-Galaxy-S23-Ultra-to-receive-new-major-camera-update-soon.700349.0.html
1300€ is way too much for 12MPix. I assume the 200MPix mode is locked for 3'rd party camera apps. Atleast give us AEB RAW bracketing. The bracketing should be just batch list compleatly customizable in WB, Shutter, ISO. With compleatly i mean the EV step is not fixed from 1 frame to another.
200 MP mode is easily accessible on S23 Ultra in stock camera app in default photo mode, you just have to select "4:3 200 MP" in aspect ratio option.
