video says it is private. I am unable to view. Anyways, I had this issue with my first infinity (which I had to return after 4 days of ownership because the screen was popping out where the dock connectors are.) At first I thought it had something to do with me having a micro sd card in. Weeks into my new one (with sd card in) and no issues with the notification panel randomly coming up!! So I definitely think it's a hardware issue. Check your infinity for the screen popping up anywhere.
My new one has been perfect!!
