my Android Screen is setup as 1920x1080 (in the Android profile). The player displays it as 1920x1008 when looking at the Status, there are black bars on the bottom and sides. All other apps show fullscreen.
If you leave the screen dimensions empty (as it is by default ie auto detect size), does the player status window reports it correctly as 1920x1080? (you might need to restart Xibo for Android after making this change in display profile).
