After swapped 4 iphone5s, I just gave up

this is the first post that I'm writing on MacRumors because i think i have to share this with u guys.

Got my iphone 5 3 weeks ago, the first thing i have noticed is the yellower and darker area at the top of the screen, it didn't go away as time passes so its definitely not a glue issue.

Went to the store and changed another one, and this time there was a darker line on the right side edge of the screen, its very obvious and the genius noticed this at the first glance when i showed the problem to him.

the third one, yellow at the top

the fourth one which was also a new unopened one, darker line on the right side edge.

have given up now and applied refund, will wait a month or two to see if the situation improves and i think its because of the problem with certain batches of stock which generally will have quality issues.

For now, the iphone 5 screen is just a joke, u guys might want to check the darker line issue too as 2 out of 4, if its not because I have extremely bad lucks, it should be a very common issue.

The darker line will be most obvious on grey background, u might want to just open AirPort and see if you have it
