Change the buttons on the Android navigation bar that's usually at the bottom of the screen. To bring back the default buttons, run the action with all blank fields.
To use this setting, Tasker needs to be granted permission to change secure settings on your device
Please follow the instructions to learn how to grant the permission.
If for some reason System UI crashes while using this action, use the following adb command to reset the navigation bar:
adb shell settings delete secure sysui_nav_bar
This will make the navigation bar back to what it was and make it stop crashing.
If you can, re-configure the action and leave all the fields empty and run it. That should make it reset as well.
This action may not work on all devices. These are the ones that I've confirmed are not working correctly:
Other devices may also not be compatible
