Many Samsung Galaxy S21 users say that green lines appeared on the display after they updated their phones.
The notorious green lines have returned to haunt some Samsung smartphone users and it looks like they cropped up for most people after they updated their phones.
As first noted by Android Authority, there has been a spike in complaints regarding green lines appearing on some Galaxy S21 models, including the Galaxy S21 Ultra and Galaxy S21 FE.
Some of the affected users say that vertical green lines popped up on the display after a software update. That’s not to say this is a software-side issue and can be fixed through an update. It’s possible that an underlying hardware defect was exacerbated by the update and manifested as green lines on the screen.
Though green lines are a fairly common issue with OLED screens and have been seen on phones manufactured by other companies, including Apple and OnePlus, as well, it’s still not clear what causes them.
