navigate buttons? Multimedia for example when you watch film on browser and during the film there are these buttons?
I think officially in new Xperias you can't hide it with specific settings (htc, motorola etc have specific settings where can you choose in which app you want to close (hide) these buttons. I know when this xz p was with android 7 and 8 it automaticaly hide these buttons. Now in pie you can't hide it and there is no automatig hider
In g. playstore you can find some hiding apps, but you must pay for this sh.t (some apps have also free part of app, but you will have color line in this part of display. You can try for example this app : gmd immersive
