The virtual button will help you easily access your phone without the need to use its physical buttons. This is more convenient and quick access to all your phone settings and a quick toggle. It is also an ideal app to protect the physical buttons (home button and volume button) from being used regularly. It is very useful for a big-screen smartphone.

Other things that you can control using the virtual button is the home, back, menu and search key. You will just need to modify the option settings. This is also free of charge and you can use it right away after downloading.
