Light Blend Mode bug

Karlsome

I chose Light Blend Mode in the Display & Theme settings, However sometimes it works sometimes it doesn’t.

So imagine going in a tunnel, and the night theme won’t activate. The screen is blindingly super bright, unless I turn on my headlamp then it activates the night theme.

I know that the light sensor is fine because my heads up display detects it.

And at day time, sometimes it is still in night mode.

How to fix this?

You can compress the image to under 2MB to upload it.
You mean manually turning on the lights can switch themes, but the light sensor automatically turning on the lights won't switch themes, correct?
Is this issue persistent, or did it appear after an upgrade?

DUDU-Meng yes if I turn on the headlamp manually, it will switch themes instantly.

But if headlight is off, and it is during the day, my DUDU7 is sometimes still in night mode, or sometimes it is in day mode. It is at random.

For example, today morning I turned on the car, the dudu7 is in night mode. But when I drive, around 20 minutes later it automatically goes to day mode without me doing anything.

It was ok when I didnt connect my Canbus yet, but when I connected my canbus, it became this.

Is there any settings that I need to set up?

I am using prius 3rd gen 2014 with canbus Raize FT-RZ-01.

Currently I chose RAV4 on the canbus list, because it is acting the same even in Prius in the list

And for example if the dudu7 is in day mode, and I go to the tunnel, it will not turn to night mode unless I turn on the headlamp.

This car's ALL+ is original, and this issue isn't related to the CANBUS box (which doesn't interpret the light output). As you noted, it sometimes works and sometimes doesn't. This indicates the device has day/night switching functionality (no missing hardware) and the settings should be correct.
The problem may be with the ALL+ voltage. Measure the voltage at pin A10 to see if it's 12V when manually enabled and 0V when disabled. What's the voltage when the automatic headlights are on/off?
