Though the main purpose of “Back Button” is to serve as an on-screen alternative to a defective back button on an Android-driven smartphone, the utility can actually function as an all-in-one alternative to the failing physical buttons or screen of a smartdevice.
Developed by ogapps, the utility can be configured to serve as an alternative notifications bar (for smartphones with defective top-portion screens) or simply function as an input/navigation alternative to the standard interface of an Android device.
