Lifeproof iPhone 4S Case Screen Pillow?

When the case is on my phone there's a pillow of air that makes it so I have to press hard for the screen to respond at all. It's very frustrating and I've tried to reinstall the phone, push the air out and followed the directions from the website. Could this be a defect? The plastic looks slightly bubbled when the phone isn't in the case. Also, there are two thin strips of plastic that are on either side of the screen. Could they be bubbling it?

I have the same problem with my life proof case and i have always thought that it could have been a defect but its not it creates a small space between your screen and the case so when you drop case face first you will not shatter your screen cause the two little bumps in front do not provide much support and plus when you take the case of you may notice on where the front camera and earpiece is that its a bit raised thus for creating that space as well. Hope this answers your question
