I've noticed that lately, in the bottom right hand part of the screen, it may crack depending on how you tap on it. I found out when I was typing and tapped for the backspace. Usually I won't notice but if I tap just a hair more strongly than usual, then I'll hear/feel it. Doesn't occur anywhere else on the screen.

Is this some that I need to worry about? Wasn't sure if this happened to anyone else.
