Why did my brand new 5S just quit working?

[iMore Question]

The screen looks like, when visible, a super pixelated, magnified UFO image in the sky. The phone seemed to go on super high magnification and then I can't do anything with it. Siri tells me I need to put in my pass code for her to work. Screen does not respond to touch. Phone does not respond to total reboot. Going to ATT tomorrow. Phone is 5 weeks new & updated to latest IOS 8!

Try pressing and holding the home and power buttons at the same time until you see an Apple logo...then release the buttons and see what happens...

Go to Apple if you can. They'll take care of you
