Hi. Just got my brand new iPhone last week, it was a red stripe on the right-hand side of the screen and I gave it back. They were done replacing it, and got it back today. And now I see a yellow stripe on the left-hand side, not easy to notice but I see it on white background. What the hell is this? Googled it and some say it will disappear after some days of use, can anyone confirm this? Can't stand to wait anymore on this god damn phone.
