Everything works fine in the 2021 version, and everything works fine on PC.

The post-processing configuration uses the default settings, and URP turns on HDR.

@ brendanduncan_u3d
Regarding the dark UI and game issues: The screen shots taken by players are normal, but the actual color rendering in the game is darker.
Therefore, you usually need to use another phone to shoot in order to see the problem. Hope this helps you.

Do you have any info on the type of phones that are having problems?
Are you doing custom post processing, or the standard filters?
Do you have anything else that might help figure out how to reproduce the problem?

  1. Dark color problem model: Oppo A5
  2. Black screen problem: HONOR Pad 8、Huawei 70S
  3. I used the default post-processing settings, did not turn on anything, and did not adjust the parameters.
  4. I do not have these models, so it is more troublesome to find the error.

There is also a 100% reproducible dark color problem, which is to turn off HDR on the camera on some mobile phones.
My settings are enabled by default.

Thanks for the notes. I’ll see if I can uncover anything.

Is there any latest news?

Sorry, I haven’t been able to get to it yet, still trying to track down repo devices. It sounds to me like driver bugs with sRGB display surfaces on those devices.

A newly discovered device also has this problem: vivo X27

The UI also has noticeable dark edges, and the entire game becomes very dark.
This problem will also occur if URP HDR is not checked, but it will be alleviated if checked.

Have you filed a bug for this, with a repo?

11

How should I submit?

12

As a bug report would be great

13

So, should I create a new theme and choose the type as BUG?

You should be able to file a bug from the editor. Just add as much info as you can, and including a repo example will be invaluable for when it gets to me. I’ve never actually filed a bug myself, I just try to fix them, but googling Unity bug report it looked pretty straightforward.
