Soft Screen???

[MILH0U5E]

I started to notice that the bottom corners of my screen (where the soft keys are) depress in when I push them. For example, I want to send a text or email, when I hit send, the screen actually moves down with my press and even creaks a little.

Anyone else notice this? Or is this just regular wear of this type of screen?

And not sure if it matters, but the lower left of my screen is SLIGHTLY raised above the chrome sides.
