If you're OK with immersive, use terminal with superuser, and type 'settings put global policy_control immersive.navigation=*', then reboot.
If you want to remove totally, decompile framework-res, go to /res/values/dimens.xml, and find 'navigation bar height' and change value to 0.0dip. You can also change 'navigation bar height landscape', to make sure it won't be there in landscape, but might be a good idea to leave it, in case you get stuck. Make sure you have a reliable navigation alternative...
Thanks for this information. First i have tried using a apktools app, but after all the process get boot looping in Sony's logo. After I tried to make from ADB, and I think I found the error. I cant recompile framework-res, after change values , can you help? I just change the values in dimens.xml, anything else. Dont need to sign, just recompile, right? It seens a easy process, idk what I did wrong...
