Help note 4 led flip cover

[Devulte]

Hi JUST GOT A QUESTION.

The case doesn't show properly when pressing the home key. Sometimes it just shows scrambled led lights and sometimes nothing at all. 10% of the times it works right and other 90 not so much.

Anyone have any ideas on why this is? I'm fairly certain this is an authentic case. And I think it's a software problem..

Thanks
