The traditional three-buttoned control gradually becomes part of the past. And if in iOS, gesture control appeared with the release of the iPhone X, then in Android the case for improving the usability of mobile devices has not yet been completed. But all this goes.
In Android Pie, management is entrusted only to one button - “Home”, the “Back” icon becomes active only at the moments provided by the operating system.
It became known that gestural navigation will be one of the main innovations of the future Android Q. Apparently, the “Back” button will completely replace the gesture, which is a wave to the left of the “Home” icon. From the innovations of Android Q, we can also mention a smoother switching between running programs and applications.
