According to a few user complaints posted on Samsung US community forums, the March 2020 security update released for the Galaxy Note 9 series may have broken the screen. It’s causing a lot of issues, ranging from screen discoloration (yellow screen tint) to decreased resolution and overheating.
Affected users have begun experiencing these issues after applying the March 2020 security patch to the Galaxy Note 9. They’ve reportedly attempted to fix the problems by clearing the cache, rebooting, and factory resetting the Galaxy Note 9, but none of these steps seem to have provided a permanent solution to the broken screen post-update.
i sent mine to Samsung and end up I have to pay for repairing the screen. They're denying it is related to software update issue and blaming the users of dropping the phone or applying pressure to the screen.
