Thanks! This is exactly what I need.
BUT the DUDUOS home screen keeps restarting the "Driving Mode Shortcut" app if it is used as the default navigation app. And it causes Google maps launched using the Driving mode shortcut app to freeze when a navigation destination is entered. The shortcut app works fine when launched manually (by selecting the app icon manually).
Is anyone else seeing this behavior? I am on the latest release build of DUDUOS 3.6. Seems like a bug.
