Grey splotches spreading across screen

[mseidman]

Hi,

Yesterday splotches began to appear around the edges of the screen underneath text. It appears as if they are at the deepest layer of the screen against the light. I don't think moisture is the issue and it seems to be operating as it should. Check out the attached photo. The phone is about 2 and half years old.

Anyone know what may have caused this issue.

Thanks in advance.
