Vertical green line on my screen

[Manila1206]

Out of nowhere, my Note 20 Ultra got a vertical green line in the middle of the screen. What is the solution? Can I use my phone for trade in?

I don't think resetting your phone fixes the problem when I asked my own samsung support they didn't bring that up

I found this answer https://eu.community.samsung.com/t5/galaxy-note-series/i-have-got-same-issue-in-samsung-galaxy-note-...

The samsung rep suggested following that support link. Wondering if anyone has tried the solution?
