I have a mystery (to me anyway) Maybe someone here can help. I downloaded CoPilot and started using. Funny thing -- when I turn the Nexus to the landscape position the screen goes dark (maybe similar to going to sleep). If I turn it back to the portrait position the screen comes back on. Turn it to back to landscape position & again it goes dark.

I wanted to blame it on CoPilot but I signed out of it and it did the same thing. It even does it on the sign in screen. Any ideas?
