Dash screen never turned off

This night I just realize the commander and dash seems never turned off, not like knob powered by the center control usb outlet.

this is causing following issues:

- dash screen never turned off(screen burn-in?)

- my phone is always connected to the carplay so never uses wifi(the signal is good so even i'm at second floor it's connected lol)

- potentially lead to intermediate disconnection between dash and commander
