iPhone 6 corner of screen popped out
So, my iPhone 6's front top left corner of the screen appears to have "popped out" (Best way to phrase it)... I don't know whether I should go to the geniuses or try to pop it back myself... It appears to have popped out of the hook inside the phone, and if i jam it a little i can put it back in, but I'm afraid that it'll crack the screen. What should I do?
iPhone 6, iOS 8.1.3
