Not only that, but with Back Button you can completely customize the button layout, and add other buttons as well as a back button. The bar is also easy to move: just long press on it to move it anywhere on the screen.
If, for whatever reason, you can't go back on your Android Device, the app Back Button can be hugely helpful. With this simple but effective app, you add virtual buttons anywhere on the screen and enjoy having a back button once again.
