Is there stock or custom rom? At me with stock rom KitKat 4.4.2 (res 1920x1080), np with notif bar and full screen, bot work, ss from my phone bellow,
Try with these command lines, you can remove show_status_bar=1, and just use command lines bellow, on my KitKat 4.4.2 phone, no problems with notif bar with these comand lines,

in your case just change has_physical_home_button=0 to has_physical_home_button=1, in command lines above, cause S4 has physical home button, my phone is without physical home button, so in my case = 0, in your =1, rest of command lines leave as they are...
