I've noticed a common complaint about the S25 Ultra’s display and camera colour accuracy, with many saying the colours seem off—especially skin tones appearing unnatural. After some deeper research, I identified the root cause: by default, the S25 Ultra has a tint level of +40, which skews colours towards blue and results in an overly greenish tone in certain lighting conditions.
I confirmed this by using the Blackmagic Camera app, which exposed the default tint setting at +40. Reducing this to 0 immediately improved colour accuracy, making skin tones look more natural. Samsung should address this issue with a software update or, at the very least, provide users with better controls to adjust tint in the default camera app.
