In the past week or so my Note 9 has begun to exhibit exactly the same behaviour; the screen gradually turn a yellow/green colour, fades & becomes almost unreadable. Some times turning the screen off/on does the trick, sometimes I have to turn the phone off and on again.
My phone is only 6 months out of warranty so I'm rather dissapointed with Samsung; there are reports of this problem reported widely online, on various forums including Samsung & YouTube & other social media outlets. This is certainly a Samsung-specific problem otherwise there would not be so many identical reports of the same problem.
Some have suggested this was due to a software update but if so, I've not experienced this problem until recently.
Having paid hundreds of pounds for a flagship phone (on the basis that I've been very happy with previous Samsung products) I think Samsung must know there is an issue and should be prepared to either issue a software update to resolve (if possible) or failing that to offer free repairs to affected customers.
This is clearly a Samsung quality-control issue so I'd be glad to hear what solution Samsung are willing to offer (and not just saying "take it to a service centre"). Perhaps the should offer a mail-in service to repair customer phomes affected by this issue?
