Hi @Bij

 

 

I've seen this before which is a hardware issue. 

 

In the interim if you turn up the screen brightness it should alleviate the issue. 

 

In in the long term you’ll need to either ask Samsung to arrange to send it to a repair centre or find your most local Samsung Experience Store or Samsung Service Centre.

 

The Manufacturing Warranty of 24 Months should cover this unless it’s got visible signs of an accidental drop or water damage.

Hey @Bij! Let's do some troubleshooting with you! Is your phone screen cracked or smashed? Is it still responsive? Let's run a service test. Type *#0*# into the dial pad and try the Green, Blue and Red tests. Are the lines still appearing during these tests?:robothappy:

If it’s something similar to this picture then your display needs replacing as it’s a hardware issue that’s known about by Samsung.
