R-just gundam case for note 4 blocking gps signal.

[AC Question]

I just purchased an R-just gundam case for the galaxy note 4,beautiful case and very comfortable to use. But I noticed on a recent trip my gps would not hold signal making my navigation function almost unless (it also interferes with pokemon go!) I was wondering if there was a work around for this because I enjoy the case. But if I have to I'll part with it. Thank you
