Loose Screen On iPhone 5c

Ive had my iPhone 5c for a little over a month and I was taking the case off and the screen popped out in the corner and I dont want to force it back in? Does anyone know if this is covered by the one year warranty that came with the phone? I've never even dropped it before. Any info would be appreciated, when I called the apple support they just left me on hold for an hour, thanks.
