Got these almost smudge like marks on my phone screen. They aren't scratches, but won't come off with a microfiber and distilled water. Never seen this on my S22 ultra.. The spots are smooth to the touch but definitely stand out. Maybe a coating on the screen thats causing an issue?
Maybe try cleaning your screen before going to Samsung support. Sorry but I do not buy that this just magically happened. I saw similar threads on the S24 and told them the same thing. I owned my S24 from two days before it released until about a month ago, I never put a screen protector on it, and never had any permanent smudges.
