I am having s20+ display issue. And i have seen in service center many s20+ software update broke. And this is not our issue. This problem is caused by an update that Samsung is giving. The solution should be done by Samsung
Go visit the service center and explain the issue properly, even I faced the same issue. They helped me with complete display and battery change FREE OF COST. They said there's some glitch from Google's software update and have caused this, all the other phones will also face this issue as it's from Google.
