I have Xolo A500S. I want to have navigation bars (soft-keys), but it does not work manually or by any app. Here is the build.prop.

  • If you have root, you can use Xposed framework and install one of the modules for soft-keys. BTW, build.prop doesn't have anything to do with having soft-key buttons.

You can add this line to the end to fix it

qemu.hw.mainkeys=0

It should enable it. I wouldn't understand why you would want soft keys, but there you go.

I would recommend you to use build prop editor in the play store. It backs up your build.prop before you do anything.
