As you can see the phone bar appear over the game when using the keyboard on a Galaxy Note 8. Maybe it not a bug but I'm submitting it anyway so maybe it could be improve in further update. It might be because of the setting auto hide the phone bar... So when the keyboard open in game he is positioned to leave space for the or something like that. It doesn't really affecte the game play or the usability of the keyboard... but it just annoying haha!
