Hi,

The brightness is way too high in the dark with auto brightness on.

I think the sensor isn't working as it should.

  • Maybe you can try and use nightlight? The problem with brightness level in the dark its highly subjective from person to person.

  • In the dark the brightness is like this.

    That's definitly wrong, should be at the minimum.

    @asusrg87 I agree, when I'm in a pitch black room in complete darkness the screen brightness only drops down to %42 and doesn't fall lower.

  • 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.

  • Same issue for me as well and it seems to stuck at 25% with complete darkness in the room
