Hey all....

Whenever I put a little bit of pressure (or press a key) in the middle area of the keyboard, (around the t y g h v b grid) the screen turns a purple-ish color. It almost looks like an inverse image but there is a purple hue to it. And it only happens in that area of the keyboard. Anybody have any ideas as what this may be?

The phone has never been wet (to my knowledge). Hasn't been dropped recently or suffered any physical harm at all since I've gotten it.
