However, this isn’t always the behavior in all cars out there, and this is why Google itself introduced a dedicated feature that allowed Android Auto to switch from the day to night mode and the other way around based on the settings of the phone. This means that the mobile device was the one to decide whether Android Auto switched to the dark mode or not, and for most users, this made perfect sense because they could therefore get more control over the UI of the app in the first place.
In some newer vehicles, Android Auto’s visual mode can track the settings of the head unit, which are based on the current status of the headlights. Android Auto can transition to dark mode automatically based on the phone’s settings. Auto-interface for Android Auto-interface for Android Auto-interface for Android Auto-interface for Android Android Auto has a user interface. In other words, when the headlights are switched off in your car, the head unit (and thus Android Auto) switches to day mode. When the headlights turn on, as they usually do when driving at night, the head unit, as well as Android Auto, go into dark mode.
Someone explains that some new cars with factory-installed DRL instruct Android Auto to use the dark mode. This means the app is much harder to use during the day because everything is barely visible, and manually switching to the day mode makes Android Auto a big mess at night. Right now, nobody seems to know what exactly to do, other than forcing Android Auto to use a specific mode for each instance of the app. The settings, however, are lost when the app closes.
However, many users are now complaining that the phone-controlled automatic day/night switching no longer works, and what’s more, it often switches to “car-controlled” when the app shuts down. A discussion thread here on Google’s forums indicates that the head unit is once again the one that’s providing the instructions on which mode to use, and more often than not, this isn’t the right way to go.
