Google has updated the navigation gesture with Android 10, completely eliminating the classic buttons. The 9to5Google site received a copy of the latest version of GMS (Google Mobile Services), discovering that smartphone manufacturers must to hide their customizations in the settings. Furthermore it is not possible to show the personalized gestures during the setup phase. The goal is to standardize operation between all devices.
With Android 9 Pie the button to access the open apps was deleted, while with Android 10 the Back button was also removed to leave room for a single small horizontal bar. During the Google I / O 2019, the Mountain View company had anticipated the future changes that will be included in the new version of the GMS. The producers will get the certification for new smartphones only if the Android 10 navigation system is the default one. The previous one to Android 9 Pie, or with i three buttons traditional, may be available as an option.
The consequences of this change are two. First of all, on the new smartphones with Android 10 there will be no Android 9 Pie two-button navigation system. The option will be selectable only on devices that will be upgraded to Android 10. The requirements of GMS also oblige the producers to hide their personalized navigation system. It may be present in the settings, but cannot be shown during initial configuration via pop-up or notification.
The navigation gestures of Android 10 are similar to those of iOS: swipe upwards to display the home screen, swipe & hold to display the open and swipe apps from the right or left side to go back. With a swipe from the lower corners you can activate Google Assistant. For swipe back, you can adjust the sensitivity to reduce conflicts with apps that use a side menu.
