Regarding the first issue: I understand that there is a permanent part of your display, that works using any application except for PUBG MOBILE, correct? If that is the case and the area on your display, that you've highlighted works fine in any other horizontally played game, then consider using the fox button, reinstall the game itself or move around the affected buttons to see if that helps.
