Google is testing new swipe gestures in Android Q Beta 2
Google is currently adding new features to the Android Q Beta on time, and these new features can be experienced with the simulator provided by Google. The latest discovered features are mainly Google’s new swipe gestures, such as the corresponding arrow indication when sliding from the left or right side of the screen. However, according to the test, the above sliding operation gestures only show that the arrow does not have a practical effect, and it seems that it has not been developed yet, so it cannot be used temporarily.
Also, when you slide up from the bottom of the screen, the bottom of the screen also uses gesture control. For interested users, you can use the Google Android Studio to create an Android emulator to experience Android Q.
However, these swipe gesture operations currently need to be turned on by the ADB command. By default, these gestures are not yet turned on.
adb shell settings put global prototype_enabled 1
