I noticed a white line on my Note 20 Ultra screen that doesn't appear on dark backgrounds. Mainly just on white and light backgrounds
When I dial Dial *#0*# into the Keypad > Select Red, Green and Blue from the series of grey tiles.
the line seems to appear only in the green screen but not in the blue and red. It's just like a hairline.

@Vetmom: If the line is visible in one of the screen tests, then you may wish to arrange for an engineer to inspect the device, as this issue is likely to be hardware related. To arrange an inspection, head to the Samsung Members app > Support > Repair service > Find a service centre, and follow the on-screen instructions. Alternatively, visit samsung.com > Scroll to the bottom of the page > Contact us, and reach out to our Support Team for further assistance.
