This is really getting under my nerves. I've gone through at least 6 replacements that all had this issue. All the replacements were F2 serial manufactured in week 36...
Some of the geniuses tell me to wait for a software update. That's a ton of BS, an iOS update is not going to fix incorrectly set voltages from the factory!
We should really be making more noise, especially on the apple support forums, apple doesn't look at macrumors and the geniuses even dismissed me for referencing this thread. Make the issue known and if we can, let's all fire an email to Tim Cook or make sure we talk to managers directly.
Going back for a replacement on Friday, I'm still within the return period and if anything I should be entitled to a no questions asked refund since I am unsatisfied with the product at this point. But alas once you replace the phone and the serial doesn't match up with your receipt, you're out of luck and all you can do is keep replacing.
Some tips if you're going in for a replacement though:
Bring a magnifying glass, helps them see the issue more clearly
Reference an image that has been floating around in this thread comparing the 5 and 5s screen.
If they agree to a replacement put the phone into recovery mode (press and hold home button and plug in a powered lightning cable) the blue iTunes icon will show if the screen exhibits the poorly calibrated common electrode voltage.
At first boot, iOS 7 is completely white so it is difficult to see the pixel inversion, do not let them take your original phone right away, I've noticed that all my replacement phones that have the interlacing effect are noticeably warmer
Remember, remain polite but make sure that you're stern, don't hesitate to speak to a manager directly. All of us are still in our return periods so they should be doing all they can to ensure we are satisfied with our phones.
EDIT:
Here's the link for the Apple Support Forum:

Make some noise here and reference that thread instead when going to the apple store for replacements, that way they can't say that MacRumors is "a site dedicated to finding issues with apple products when there aren't any" (I swear one manager said that to me)
