I think I'm a little late to the party here, but I recently noticed that on my iPhone 5C, the screen was coming out of the case in one corner. I dropped it on carpet the other day - not hard enough to do any damage - but I guess the case is flexible enough under pressure that the corner came off a little. Anyway, after reading the same problem on another forum, I put the phone face-down on my desk with a cloth under it to prevent scratching (I used a tshirt, but anything will do) and then applied pressure with my hand until it popped back in with a nice, loud pop. Worked great for me! Hope this helps you.
