My Iphone 5c screen came out a little?

I dropped my Iphone and although it didn't crack the corner is bumping out a little bit. I'm scared to push it back in

Well you should have gotten a Nokia Lumia 1020! Wouldn't have happened!

The screens are held in by glue, nothing else. The glass itself is connected to the phone via a small cord that is very sensitive. Don' force it in. But it can ruin the connection with the glass and the brain of the phone if the glass is pulled up to far. If it doesn't go in easily, go to your nearest apple store
