According to a latest report, Google will remove the back button from the next version of Android – Android Q. Read this article for more details.
If you are an Android user, you must be familiar with the navigation buttons – back, home, and recent – that sit at the bottom of your device. However, with Android 9.0 Pie that was released last year in August, Google introduced navigation gestures. On Android Pie, you don’t get the recent button. You only get a pill and a back button. But, it looks like Google will ditch this back button with the next version of Android – Android Q.
