Samsung Galaxy Flip 4

[Flowry]

I have a green line across my screen where it folds How do I get rid of it?

[BandOfBrothers]

First try bring up the colour test panels by typing into your phone dialer pad *#0*#

If cycling through the colour test panels does not help, then a line of pixeks have possibly failed, and or the connection between the screen and internal motherboard has possibly failed. 

You'll need to let a Samsung Service Centre have hands on @Flowry 

If i can be of any further help please don't hesitate to ask  😎

That usually mean a pixel has been damaged or burnt

I sent my phone off to be repaired. I got a quote back for £249. It seems it is not covered by warranty because impact damage IMEI and it needs a new OLED screen.

Robbing swines tried to charge me £420 to repair mine after 5 months. No damage to it at all. Absolute scam artists.

If anyone has any contact details for me to escalate the problem I'd be very grateful.
