Virtual Navigation Bar for Touchwiz ROMs on Samsung Galaxy Devices topic

This thread will explain how you can get on-screen virtual navigation buttons on any Touchwiz ROM for Samsung Galaxy devices.



Note: The same can also work for any other Android device but results may vary. Supports all droids from Android 4.1 to 4.4.4. You may however experiment after taking a Nandroid backup. :p

Steps:
- Open your file explorer app with root permissions. (E.g. ES File Manager with Root explorer enabled)
- Go to /system
- Open build.prop file.
- Edit the file to add this at the bottom - qemu.hw.mainkeys=0
- Save and exit
- Reboot the device.

Note: Do not disable hardware keys using other mods as they are required in rare instances where an app cannot force immersive mode. Only turn off the 'Touch key light duration' under Display Settings.

How to force immersive mode for apps where navigation bar does not appears:
- Install Xposed
- Download App Settings mod.
- Activate and Reboot
- Open the App Settings and select the app you want to force immersive mode. E.g. Camera app and Select Immersive under Fullscreen option.
- Save settings and launch the app.

Additional goodie: To get Android L style nav bar, use the Xposed mod - 'Lollipop Navigation Bar'
