My new iphone 5s is having issues with the screen. Exactly the bottom half of the screen shows a number of vertical bars. I did a restore and didn't help. Wondering if anyone else is seeing this. It is not permanent, sometimes the screen clears up and suddenly the bars come back. Hopefully you can see in the attached pic I took with my mac. The bars don't show up in pics I capture with the phone itself (screenshots) As I type this, the bottom half of the screen is actually flashing now. Looks like I got a bad phone.
