LG is bringing a bit of customization out of the box with customizable nav buttons on the G3. The standard nav button layout for the G3 is Back-Home-Recent, but you can change up the layout or change the buttons altogether if you like. You can add buttons for accessing notifications panel, quick memo, qslide, and dual window. You can even change the background color of the nav bar! There are options to make the nav bar transparent, and you can choose which apps to hide it in. To change the settings simply acces settings, display, home touch buttons. I would love to see these kinds of customizations make their way to other devices without root!
