Hi,
The brightness is way too high in the dark with auto brightness on.
I think the sensor isn't working as it should.

Hello everyone!
I am sending the issue to R&D as I was able to recreate this.

I got a reply from R&D and I would appreciate if you could follow these steps and tell me if this solves the issue.
1. Launch the calculator application and enter .12345+= to activate the SMMI test. Select Single Test > Light Sensor Test. To check if the Light sensor is normal。
2. Into Settings > Apps&notifications >See all apps>Click the menu in the upper right corner >Show system, And click the search icon in the upper right corner >search "Device Health Services" >Tap and enter App info page>Storage&cache>Mange space>Click "Reset adaptive brightness">OK.
This should clear out the cache memory of the Adaptive Brightness, if this is still an issue after doing this please tag me so I can go forward with the investigation.

HI Mattias,
I have done a reboot as well at the end of the steps, it does not solve the issue. The auto brightness is still at the same level as in post number 3 in a fully blacked out room. In my opinion it should be zero

My phone also behaves exactly like this.
