When I close the cover, the screen doesn't change to the black&white lock. Instead, nothing happens. The strange thing is that sometimes it would start working all of a sudden, then it stays working until I remove the phone from the case and put it back in, after that it doesn't work again and who knows when it will suddenly start working again.
It's strange and a little annoying... I wonder what could be causing this?
