The Galaxy S20 was a big deal for Samsung as it ushered the series into a new era. Sure, there were some people that did not like it as much but if that phone proved anything, it was that Samsung is not messing around. However, a few months ago, years after the phone's launch, users started talking about how the device displays were doing, and in most cases, the phones were out of warranty which means that the users had to pay out of their pockets for the screen replacement.

However, it now seems like the issue is widespread as more users have started reporting that the screens of their Galaxy S20, S20+, and S20 Ultra are displaying a green or pink line that is running down the screen. For several users, this issue happened after a recent update, but many users have also reported that the issue has been showing up before the update. This only suggests that a software update is not something that is causing the issue.
