Menu Button (No root)

The app Menu Button makes it possible to add buttons to the screen of your device and use them for all kinds of features: raise or lower the volume, return to the home screen, go to the options menu, open an app, control the rotation, and much more.

By default, Menu Button adds a menu with four items to the right side of the screen. That being said, you can customize each and every feature of your new menu from the app's options menu. From that menu, you can change the icon, size, and opacity of each button, as well as add or remove a background color.

Not only that, but Menu Button also allows you to set exceptions for your apps. Normally the menu is always visible, but this interesting feature means you can manually disable it. This allows you to disable the menu while playing games or watching videos, or only enable it for specific apps.

Menu Button is a very useful personalization app that you can use to create a custom menu bar for your Android device and do almost anything with just a tap.
