How the CHIGEE Display adjusts brightness
The CHIGEE Display uses its ambient light sensor to auto-adjust screen brightness (brighter in daylight, dimmer in the dark) for comfort and visibility.
How Android Auto handles Day/Night
Android Auto’s theme (light/dark) is independent of the CHIGEE Display’s auto-brightness. It does not switch based on ambient light from the display. You need to choose the theme in Android Auto settings.
You can select Light, Dark, or Automatic in Android Auto settings.
Even if CHIGEE auto-dims in a tunnel or at night, Android Auto won’t change theme unless you select your preferred option in its settings.
This is a design limitation of Android Auto, not an issue with CHIGEE hardware or firmware.
Set it up (Android)
Open the Android Auto app on your phone.
Go to Settings → Theme (wording may vary by Android/AA version).
Choose Light, Dark, or Automatic (follows Android/AA behavior—not CHIGEE’s light sensor).
FAQ
Will choosing “Automatic” make AA follow ambient light?
No. “Automatic” follows Android/AA’s own logic (e.g., system theme/time), not CHIGEE’s sensor.Why doesn’t AA change when the display dims?
Because AA theme is not driven by the display’s brightness; set your desired theme in Android Auto → Settings
