I’m using a Galaxy S23 (purchased in October 2023), and recently I noticed a thin vertical green line appearing intermittently on my display. It doesn’t show up in screenshots, and I’ve confirmed it’s not app-specific.
What I’ve tried so far:
Restarted the phone (line disappeared briefly but came back)
Ran diagnostics (no issues found)
Took a screenshot — line not visible
I'm out of standard warranty now, but I’ve heard some users got free screen replacements under similar cases, even after warranty, due to known AMOLED defects.
Has anyone here faced the same issue with the S23? Did Samsung cover it for you under warranty or offer any support?
