Strange graphical issues on iPhone 5

[Jamess9046]

Occasionally when using my iPhone I get coloured lines flicker across the screen. I've already had my phone replaced once and have experienced this on both. Anyone else?

I noticed it once on my keyboard while doing a text on the first day i had it...never again after that. If it becomes a problem, trade it...great thing about Apple is they'll do it with only minimal effort on your part.
