When you or the device locks, the screen is blank, so there is nothing to display on the car’s screen. Its primary operating function with no magic or spells working in the background. Hence, keep the phone’s screen unlocked to keep Android Auto working. 

Furthermore, the phone screen must be unlocked when the car connects to Android Auto. If you lock the device’s screen while pairing, the device will connect to the vehicle via Bluetooth or cable, but the screen will only show on the phone rather than the car screen. Thus it is essential to keep the phone unlocked at all times.

Any other disconnection issues can be due to a screen saver in the phone. Make sure to turn off the screen saver before you pair up the Android Auto.
