Bug Android Auto on Nubia X

When I use Android Auto everything works, but afterwards I unplug the USB Cable, the device is unusable. The display is flickering, and no input is possible. The only thing I can do is reboot by long press power button.

This can be replicated every time by using Android Auto and unplugging USB Cable.

Thanks for any tips in this case
