SMS dissapeared?

[Chuckcell]

My Google SMS app screen has gone blank! Entirely white, no conversation displayed at all. WTF!?

Try a black background. The text is probably in white, so it doesn't show on a white background.

Well text was black (on white). And after a restart all my SMS conversations came back.
File under d---d if I know!
