Screen flashing when pressing home button

Hi,
I've been having screen issues with my phone. First green lines started showing on the screen, I turned auto brightness off, and it fixed the issue. But now when I want to wake my phone, it flashes white, but the screen stays off, and it does this for~3 more clicks, the fourth one turns the screen on though.
I'm on stock by the way. Not rooted.
Figured I'd ask before taking it to Samsung.
