The exact manifestation of the error seems to vary from situation to situation, but it is safe to assume that the problem is indeed related and most likely caused by the same potential failure. Although we will not call the affected Note 9 unit unusable, if you cannot see them after a few hours of screen discoloration, you will not be blamed.
Some photos shared by the affected users showed their plight, even painful for only a few seconds, let alone endure, until Samsung introduced some kind of repair method. To make matters worse, the company does not seem to be aware of the software-related root causes of these display problems, even though these problems seem to have begun to show up after the security update in March 2020.
For the time being, nothing seems to be able to restore the device to a normal state for more than a few minutes. Therefore, Samsung "product experts" recommend bringing the defective Note 9 device to the official repair center to check whether the defect is related to hardware. all. Again, due to the Corona Virus pandemic, this may not be possible in many places, which means that some people may be stuck waiting for software fixes … this will never happen.
