You can use Obscured/Unobscured events. But there are some limitations:

This event is raised when the lock screen is engaged or when some other action obscures the running application’s frame, such as an incoming phone call.

  • there is a delay. You got the Obscured event after screen locks. So, if you try to check the state and navigate to other page, your app may be killed by OS.

public App()  
{  
RootFrame.Obscured += Obscured;    
RootFrame.Unobscured += Unobscured;    
}
