Please send the headlight on/off status to navigation apps as TMAP, NAVER MAP, ATLAN.
It's night mode, as shown in the picture below. It automatically switches to night mode when the headlights turn on, especially when passing through the tunnels, but the navigation in the middle, music app on the right, is set to automatically switch, but it still looks like it's daytime.
As shown in the picture below, apps are converted to night mode as shown below when passing through the tunnel. Strangely, when driving in Android Auto Mode, it switches well day and night when the tunnel passes.
