Even the replacement unit has the same problem.

That is odd. I had an issue long ago with an lg phone. I started having trouble with software. Got a replacement and the same thing. Have you looked at units that stores have in display ?

[jaafar98]

Yes

[patriciostarr]

Have you seen those lines too or just the units you received

[jaafar98]

Many users complain about the same problem, and even with the replacement of the phone under warranty, the problem appears with the new phone.

Hello, We understand how upsetting screen issues are. For issues with grainy lines or dead pixels, you can find some steps here that may help. First is to see if third-party apps are causing this behavior, using Safe Mode. If the display is better in Safe Mode, then uninstall apps until the display is not grainy: https://www.samsung.com/us/support/answer/ANS00062983/

After that, try a factory reset. Back up everything you can prior (https://www.samsung.com/us/support/answer/ANS00060517/) then perform the reset: https://www.samsung.com/us/support/answer/ANS00062029/
