You can command the screen with voice command, no need of smartphone, no need of a specific application on your phone... When you show your phone's screen on the Xpeng X9 back screen, you should not have to show an application to be able to adapt the TV screen! It iw much much better thaj wjat you say, abd this is a vehicle seetvicung you and all others human beings, not requesting you to manage it oartially, even by using your unsmart phone, which waits for your commands and which does kot anticipate them as the X9 does!
