With Expert RAW, Samsung has created an app that offers plenty of features for budding photographers, including full manual controls and the ability to save in RAW. Initially restricted to flagship smartphones like the Galaxy S21 Ultra and Galaxy S22 Ultra, Expert RAW will soon be available other devices. Expert RAW will remain a Samsung Galaxy-exclusive feature though, unfortunately.
