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?

If you go into the phone dialer app
Dial *#0*#
You get three colour test cards at the top
If the line disappears in these tests
Then you will have an app or theme that's causing the screen issue
If the line is still there in the test cards. Its likely you need to book the phone in for a repair

Hi @Manila1206 

Unfortunately Samsung may not accept your phone for a Trade In due to it's current status with the green line. 

Check the Trade In faqs. 

The green line on my phone came about due to a faulty connection between the phone's display and motherboard. 

This can only be fixed by a replacement display and ribbon. 

Seel support from your most local Samsung Service Centre or call Samsung to arrange to ship the phone to them.

If I can be of any further help then please don't hesitate. Take care.  😎

Same issue with my note 20 ultra 5g. I was making video and the phone became very hot and suddenly the green vertical line appeared on the screen and can't be erased.

I won't be using Samsung for a long time. My experience with note 20 ultra 5g is very bad. The phone battery do not last and it's not adaptable with basic phone accessories like power banks and power cords. I'll like to try the iPhone.
