A vertical pink line appeared on my screen 2 days ago. I saw it appear as I was using my phone. I suspect that this is because of the new software update (Android 12, One UI 4.0). I updated my phone last Jan 19 and upon some research, many other users have been complaining about this issue—even a lot with the same model as me! To anyone saying that this is an issue with my display which is a hardware issue, I really doubt because I've had this same problem about 4 months ago but it's a faint vertical green line with the same position of the current pink line. It was resolved after I installed a software update, it just magically disappeared. I really hope that Samsung publicly addresses this issue with the new software and S20 phones. I'm really frustrated, it bothers me a lot. Hoping that a software update to fix this will be released as soon as possible.
As you can see, the pink vertical line is very bright and visible.
This one.
Hi @PasteR, the last update I got was still the Android 12 update. I guess the release of the Feb update varies for different devices. Here's a photo:
