iPhone 5S Screen Quality (Serial DN vs F2)

F1 - No issues.

My third replacement which is a F2 has no problems. (flickering/interlacing.. etc.)
Replaced a C39 for due to touch ID and yellowing on screen.
Replaced a DN for the same problem with yellowing and the  genius said it was glue spots.
The replacement screen is more vivid than the first one I got.
Its a lottery with all builds.

What is the serial# correlation for the 5S? Are there any DN or C3 serial AT&T out there? Every single one I've ever seen has been F1 or F2. And at the Apple store, all the Verizon phones are DN.

My C39 screen has perfect colors etc, but a huge cluster of stuck/bright pixels. I'll have to swap it soon, but I was waiting until they'd gone through a couple of revisions on the production lines.

Mine is an AT&T C39 with no color issues nor interlacing. I cannot tell any difference from my 5.

C39 - no screen issues at all

This is mine and starts with DN

I have a DN and I'm in total love with it. Beautiful screen, no rattles or loose buttons, nada.

I'm still just upset it doesn't support band 7 cause I live in Spain now, but it is remarkably faster than my old phone, The 3G.
I got that 3G on the night of the release and it still works. I keep it as a backup phone for traveling to dangerous countries.

Had 2 x F2 - No interlacing issues but the screens were yellow and washed out.
Had 2 x F1 - First one had terrible interlacing issues. Gave me a headache. No lose buttons, beautiful, crisp white screen, vibrant colors. Interlacing made me take it back. My phone now, F1 number 2, minimal interlacing to the point where it's noticeably maybe once a week. Screen is beautiful, crisp white. Vibrant colors. Power button a bit lose but it's fine. Keeping it.

If you think a serial number guarantees a good or bad screen, you are in no uncertain terms, delusional, misinformed, and since it's been said many times but you refuse to listen, deaf.

Ditto.
I was at the 5th Ave store today and checked some of the phones. The phones manufactured at the same factories had both bad and good screens in terms of interlacing. So it is a lottery indeed.
