Screen discoloration software bug on SAMSUNG GALAXY NOTE 9

It feels like my screen is having blue light filter on all of the time at full and low brightness and greenish screen coloration in mid level brightness.


I have searched for lots of solutions, but at the end the problem seem to arise from software rather than hardware. I am still using it and hurts my eye to use it all full brightness.  If my eyes proves to be damaged by this full brightness SAMSUNG its your responsibility call.


I have seen community post complaining of this since 2020 few got solved by activating AOD but not for many of us. Fix this bug.


NOTE: I have contacted samsung service and they said it's issue from software issue itself and they are unsure if it will be fixed after display replacement
