Agreed. FWIW, I saw a gent on Reddit say that he has a V30 and has no screen issues.
Now, a sampling of just one individual means very little. But it's a reminder that like all phone issues, it's not 100% widespread.
Heck, Samsung phones may not have uneven backlighting, but they have had all sorts of crazy color hues this year if I'm not mistaken. I think @GrumpyMom said that she experienced this.
Yeah, my first few S8's (and the S8+) I tried had really bad pink edges, even on the top and bottom. And no changing of the color temperature sliders in settings helped. It was so bad on a total of 3 models I tried that when I went to return them, they were met with shock on how bad the pink edge issue really was. But I did finally get a perfect S8 screen and I never even had to touch any of the color temperature sliders. I feel like my Note 8 screen is perfect albeit the edges may be ever so slightly green if I look at it long enough. But it's not so much so that it bothers me or that I can tell in everyday usage.
