The navigation gestures are one of the new features in Android Q and introduced in Android Pie. Android Q is currently in the fifth Beta release. However, this version completely blocks gestures in third-party launchers.
This was discovered through the XDA Developers Forum. The following image shows a device running the Android Q Beta 5 along with the famous New Launcher.
As you can see, the gesture navigation option is unavailable. It only remains for the user to configure 2-button or 3-button navigation, as in classic Android.
In the forum, it is indicated that users can force the system to accept gestures even with the New Launcher. This requires using the command line and the result is stuffed with bugs and errors.
One more step for Android to look like iOS?
For now, it is not known whether this will be a permanent decision or something experimental. It is important to note that Beta versions of the new Android may contain options and features that do not reflect the final operating system.
However, if this change comes to fruition, it will not please many users who cherish Android for their customization. Certainly, comparisons will be made to iOS and its closed system, as already done in relation to the gestures.
