After a software update, my note 9 turns greenish and abit yellowish. Whatever i do cannot resolve this irritating issue and i am very disappointed to samsung brand as they did not solve this issue on their next software update. This note 9 is well working, just that the display was so awful. Samsung pls take this issue seriously, as I saw online majority of the note 9 users face this irritating issue.
I think u better make an appointment go and check ur screen, sometimes it could be software issues, but if it is hardware issues, better visit sercive center. Members app can do it.
